i'm really getting tired of the questions like these lol
Step-by-step explanation:
(3x+3)(x+2)=
3x^2+6x+3x+6
=3x^2+9x+6
we get quadratic equation
find discriminant:
D=b^2-4ac=81-72=9
x=(-b±√D)/2a
x1=-6/6=-1
x2=-12/6=-2
one of the x values should be correct.
but why when I try to put values I get zero

The histogram to the right represents the weights (in pounds) of members of a certain high-school mathmath team. How many team members are included in the histogram?
Answer:
13 team members are included in the histogram.
Step-by-step explanation:
Consider the provided information.
The required histogram is shown in the figure.
We need to find the team members included in the histogram.
For this, we will add the frequency or the height of each bar.
2+1+1+5+1+3=13
Hence, 13 team members are included in the histogram.

4/3=-6e-5/3
solve for "E" plz
Answer:
e=-1/2
Step-by-step explanation:
4/3=-6e-5/3
Multiply both sides by 3:
4=-18e-5
Add 18e to both sides:
18e+4=-5
Subtract 4 from both sides:
18e=-9
Divide both sides by 18:
e=-1/2

Answer:
The line test is the third graph that shows a vertical line with two points plotted.
Step-by-step explanation:
A line test is used to determine if a graph is a function. Every input should only have one output. Since when she inputs 1.5 she gets two different answers it is not a function.

Which angle must also measure 85°?
22
0_5
_11
Answer:
angle 11 they are vertically opposite.
∠11 must also be 85 degrees.
What are vertically opposite angles?Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal. They are referred to as vertical angles at times.
As per the given data:
∠9 = 85°
From the diagram, ∠9 and ∠11 are vertically opposite angles.
∴ ∠9 = ∠11
∠11 must also measure 85°.

Write an equation in slope-intercept form perpendicular to the given equation through the given point
Y = -3x + 4
(6,-2)
Answer:
The equation in slope-intercept form perpendicular to the given equation [tex]y = -3x + 4[/tex] through the given point (6,-2) is [tex]\mathbf{y=\frac{1}{3}x}[/tex]
Step-by-step explanation:
We need to write an equation in slope-intercept form perpendicular to the given equation through the given point
y = -3x + 4
(6,-2)
The general equation in slope intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding slope:
The given line is perpendicular to required line, so there slopes are opposite
The slope of given line [tex]y = -3x + 4[/tex] is m = -3, (By comparing it with general equation y=mx+b, we get m = -3)
The slope of required line is: [tex]m = \frac{1}{3}[/tex]
Finding y-intercept:
y-intercept can be found by using slope [tex]m = \frac{1}{3}[/tex] and the point(6,-2)
[tex]y=mx+b\\-2=\frac{1}{3}(-6)+b\\-2=-2+b\\b=-2+2\\b=0[/tex]
So, we get y-intercept b =0
Equation of required line:
So, the equation of required line having slope [tex]m = \frac{1}{3}[/tex] and y-intercept b =0 is:
[tex]y=mx+b\\y=\frac{1}{3}x+0\\y=\frac{1}{3}x[/tex]
So, the equation in slope-intercept form perpendicular to the given equation [tex]y = -3x + 4[/tex] through the given point (6,-2) is [tex]\mathbf{y=\frac{1}{3}x}[/tex]
Determine the intercepts of the line.
y=8x - 18
y-intercept:
x-intercept:
Answer:
y-intercept: -18
x-intercept: 9/4
Step-by-step explanation:
Substitute x = 0, we find that y = -18 i.e. the y-intercept is -18.
Substitute y = 0, we find that x = 9/4 i.e. the x-intercept is 9/4.
ABCD shows the original location of a shape. FGHI shows the shape reflected across a
vertical line. If the length of side AB is 5.8 units, and the length of side CD is 8.1 units,
what is the length of side FG?
B
D
O A 5.8 units
OB. 8.1 units
OC. 11.3 units
OD
13.9 units
Answer:
A. 5.8
Step-by-step explanation:
if ABCD was reflected to FGHI means that A became F and B became G so AB became (was mapped to ) FG after reflection.
the length ( or distance) after reflection is is preserved ( does not change) so
if AB = 5.8 units then FG =5.8 units.
You were in the car with a family member. You started with 7/10 of a tank of gas, and when you got home you had ⅓. How much gas did you use?
9514 1404 393
Answer:
11/30 of a tank
Step-by-step explanation:
The amount used is the difference between the starting amount and the ending amount:
7/10 -1/3 = 21/30 -10/30 = 11/30 . . . . of the tank

Work out the area of the circle.
Answer:
perimeter of circle=2πr
16=2πr
r=16/2π=8/πcm
now.
area of circle=πr²=π(8/π)²=π×64/π²=64/(22/7)=64×7/22=20.36cm²

what is the missing term of ..9, __ , 19
Answer:
The answer could be anything, but if it's an arithmetical sequence, then it's 14.
Step-by-step explanation:
I'm assuming that the added numbers always stay the same, meaning it's linear. If you add 5 to 9, you get 14. If you add 5 again, you get 19. Another way of doing this is (19-9)/2 = 5, then 9+5=14.
