Step-by-step explanation:
I'll assume the equation is:
f(x) =x^2− 9 [assumes the "x2 is meant to be x^2]
f(x) =x^2− 9
f(24) = (24)^2 - 9
f(24) = 576 - 9

What is the value of y in the equation 3(3y - 9) = 0?
a - 1
b - 3
c - 4
Step-by-step explanation:
Use the Distributive Property in order to solve.
Distributive Example:[tex]a(b+c)=ab+ac[/tex]
Using the property into the equation:
[tex]3(3y-9)=3(3y)-3(9)=9y-27[/tex]
[tex]9y-27=0[/tex]
Add 27 to both sides:
[tex]9y=27[/tex]
Divide each side by 9:
[tex]y=3[/tex]
b is correct.

Write an equation in slope-intercept form for the line with slope 2 and y-intercept 5. Then graph the line.
Answer:
y = 2x + 5
Step-by-step explanation:
Slope-intercept form: y = mx + b
where:
m is the slopeb is the y-intercept (when x = 0)Given: a line with a slope of 2, and y-intercept of 5
Equation: y = 2x + 5
y-intercept: (0, 5)Randomly select y-values that will help you graph the equation:
when y = -9:
-9 = 2x + 5 [subtract 5 from both sides]
-9 - 5 = 2x
-14 = 2x [divide both sides by 2]
-14 ÷ 2 = 2x ÷ 2
-7 = x
coordinate: (-7, -9)
when y = -5:
-5 = 2x + 5 [subtract 5 from both sides]
-5 - 5 = 2x
-10 = 2x [divide both sides by 2]
-10 ÷ 2 = 2x ÷ 2
-5 = x
coordinate: (-5, -5)
when y = -1:
-1 = 2x + 5 [subtract 5 from both sides]
-1 - 5 = 2x
-6 = 2x [divide both sides by 2]
-6 ÷ 2 = 2x ÷ 2
-3 = x
coordinate: (-3, -1)
when y = 3:
3 = 2x + 5 [subtract 5 from both sides]
3 - 5 = 2x
-2 = 2x [divide both sides by 2]
-2 ÷ 2 = 2x ÷ 2
-1 = x
coordinate: (-1, 3)
With these coordinates, graph them on a coordinate plane and draw a straight line through them. That should be the graph of the equation.

Mario collects seashells and sells them to tourists. The function s(t) approximates how many seashells Mario collects per hour. The function W(h) represents the number of hours per week Mario spends collecting seashells. What are the units of measurement for the composite function s(W(h))? seashells over hour seashells over week hours over week weeks over seashell.
Composite functions are function of functions. The unit of measurement for the composite function s(W(h)) is number of seashells collected per hour.
What are composite functions?Functions which are formed by composing two or more functions in a way that one's input is another's output unless its the last and first function is called composite functions.
Since we're given that:
s(t) = function approximating number of seashells collected per hour
W(h) = number of hours per week spent by Mario
Thus, W(h) outputs number of hour (the time t) and when we do s(W(h)), we give s the time t.
The function s then outputs the speed (the rate of number of seashell collected per hour)
Thus, output of s(W(h)) is the rate of number of seashells collected per hour.
Thus,
The unit of measurement for the composite function s(W(h)) is number of seashells collected per hour.

https://brainly.com/question/24780056
Answer:
the answer is seashells/week
Step-by-step explanation:
because you are trying to find s(W(h)) it starts with S right? so seashells would be on top, then what is the second one? it is W so then because W represents week and H represents hour. So the answer is seashells/week

What is the quotient of 840 divided by 28 with a remainder?
Answer:
30
Step-by-step explanation:
There is no remainder. You can do 84/28, which is 3, but since it is tens place, 30. You can not divide 0 to 28, so it is 0. 30+0=30
Answer:
840 28 = 30
30 = 300 to the nearest tenth
30 = 30 to the nearest hundredth
30 = 30 to the nearest thousandth
= 0 to the nearest tenth

OB) P(-4,-4) and Q'(-1, -2)
OC) P (4, -4) and Q'(1, -2)
OD) P(-4,0) and Q'(-1, -2)
Will mark brainliest
Answer:
B) P' (-4, -4) and Q' (-1, -2)
Step-by-step explanation:
From inspection of the graph:
P = (-4, 4)
Q = (-1 ,2)
If the line PQ is reflected across the x-axis, then the x-coordinates of the points do not change, and the y-coordinates of the points become negative.
Therefore,
P' = (-4, -4)
Q' = (-1, -2)
Reflected over x axis so x co-ordinates remains constant.
The line is present in Quadrant 2 so it will be shifted to quadrant 3.
y co-ordinates will be negative.(In Q3 y<0)So the rule is (x,-y)

Answer:
(a) 1232 m²
Step-by-step explanation:
The surface area is the total of the areas of the two triangular ends and the three rectangular faces.
Each triangle area is ...
A = 1/2bh
A = 1/2(24 m)(7 m) = 84 m²
The sum of the areas of the rectangular faces is ...
A = LW . . . for each of the 3 faces
A = (19 m)(24 m) +(19 m)(7 m) +(19 m)(25 m) = (19 m)(24 +7 +25 m)
A = (19 m)(56 m) = 1064 m²
Then the total surface area is ...
A = lateral area + base area
A = 1064 m² + 2(84 m²) = 1232 m² . . . . total surface area

A triangle with sides of 5, 12, and 13 has both an inscribed and a circumscribed circle. What is the distance between the centers of those circles
Answer:
about 4.03 units
Step-by-step explanation:
The incircle of a triangle is tangent to each of the sides. The points of tangency from a given vertex are the same lengths. In a right triangle, the points of tangency from the right angle are equal in length to the radius of the incircle. These facts let us write an equation for the perimeter of the triangle in terms of the incircle radius and the side lengths:
2(r) +2(a -r) +2(b-r) = a +b +c
2a +2b -2r = a +b +c . . . . . simplify
a +b -c = 2r . . . . . . . . . . . add 2r -a -b -c
r = (a +b -c)/2 . . . . . radius of the incircle
For our triangle, with a=5, b=12, c=13, the radius is ...
r = (5 +12 -13)/2 = 2
In our diagram, if point C is the origin, the coordinates of the incenter (D) are (2, 2). The circumcenter (E) is the midpoint of the hypotenuse, so will have coordinates (b/2, a/2) = (6, 2.5).
The distance formula can be used to find the distance between D and E:
d = (√((6 -2)² +(2.5 -2)²) = √16.25
The distance between the incenter and circumcenter is √16.25 ≈ 4.0311.

Additional comment
In the attached diagram, we used angle bisectors to locate the incenter. This was done before we realized how simple it was to calculate its location.

Solve the 5 questions. I beg you T_T (90 points!!!)
Answer:
8) Consistent and Dependent
[tex]\boxed{\begin{aligned}3x-3y&=6\\-x+y&=-2\end{aligned}}[/tex]
9) Consistent and Independent
[tex]\boxed{\begin{aligned}x+y&=0\\-x+y&=-8\end{aligned}}[/tex]
10) Inconsistent
[tex]\boxed{\begin{aligned}4x&+2y=6\\4y&=-8x+4\end{aligned}}[/tex]
11) Solution: (3, 0)
12) Solution: (-2, 1)
Step-by-step explanation:
System of equationsA consistent and dependent system has infinitely many solutions. When graphed, the equations will result in overlapping lines, forming a single line.A consistent and independent system has a unique solution. When graphed, the equations will result in two lines that intersect at a single point.An inconsistent system has no solution. When graphed, the equations will result in two parallel lines that never intersect.[tex]\hrulefill[/tex]
Question 8The graph shows a single line, so the system is consistent and dependent.
Find the equation of the line by calculating its slope (m) and y-intercept (b), and then inputting these into the slope-intercept formula, y = mx + b.
The line passes through the points (0, -2) and (2, 0).
Input these points into the slope formula to calculate the slope of the line:
[tex]\textsf{Slope ($m$)}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-(-2)}{2-0}=\dfrac{2}{2}=1[/tex]
The y-intercept is b = -2.
Therefore, the slope-intercept equation of the line is:
[tex]y=x-2[/tex]
Rearrange this by subtracting x from both sides:
[tex]-x+y=-2[/tex]
Therefore, the correct set of equations for the given system is:
[tex]\boxed{\begin{aligned}3x-3y&=6\\-x+y&=-2\end{aligned}}[/tex]
[tex]\hrulefill[/tex]
Question 9The graph shows two lines that intersect at a single point, so the system is consistent and independent.
One of the lines passes through the origin (0, 0).
The only set of equations where y = 0 when x = 0 is the set with the equation x + y = 0.
Therefore, the correct set of equations for the given system is:
[tex]\boxed{\begin{aligned}x+y&=0\\-x+y&=-8\end{aligned}}[/tex]
[tex]\hrulefill[/tex]
Question 10The graph shows two parallel lines, so the system is inconsistent .
Find the equation of one of the lines by calculating its slope (m) and y-intercept (b), and then inputting these into the slope-intercept formula, y = mx + b.
The first line passes through the points (0, 1) and (0.5, 0).
Input these points into the slope formula to calculate the slope of the line:
[tex]\textsf{Slope ($m$)}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-0}{0-0.5}=-2[/tex]
The y-intercept is b = 1.
Therefore, the slope-intercept equation of the line is:
[tex]y=-2x+1[/tex]
Multiply all terms by 4:
[tex]4y=-8x+4[/tex]
Therefore, the correct set of equations for the given system is:
[tex]\boxed{\begin{aligned}4x&+2y=6\\4y&=-8x+4\end{aligned}}[/tex]
[tex]\hrulefill[/tex]
Question 11The solution to the graphed consistent and independent system is the point where the two lines intersect.
From observation of the given graph, the point of intersection of the two lines is (3, 0).
[tex]\hrulefill[/tex]
Question 12The solution to the graphed consistent and independent system is the point where the two lines intersect.
From observation of the given graph, the point of intersection of the two lines is (-2, 1).
