Answer:
Graph A
Step-by-step explanation:
The y-intercept is -3, which is the y-value when the graph hits the y-axis.
Graph A and B both hit the y-intercept of -3.
The slope is 3/4, which means the line rises 3 units as it runs 4.
This time, only Graph A has the correct slope.
The correct answer is [tex]\boxed{\text{Graph A}}[/tex]
-Chetan K
Answer:
Graph A
Step-by-step explanation:
The formula is in the form y=mx+c, where m is the gradient and m is the y-intercept, this means that the y-intercept is (0,-3) which rules out Graph B.
To find the gradient we use [tex]\frac{rise}{run}[/tex], this means that the vertical value has to be 3 and the horizontal distance 4 and this rules out Graph C as its gradient is 3/2. That means that graph A matches the equation the best.

f(g(x)) = f(4x² - 4) = 3(4x² - 4) + 1 = 12x² - 12 + 1 = 12x² - 11the area of a trapezoid is 42 square feet and its height is 4 feet. the length of one base of the trapezoid is 9 feet. what is the lenght of its other base
Answers
Answer:
12
Step-by-step explanation:
area of a trapezoid :
[tex]A = \frac{a+b}{2} h[/tex]
where a and b = length of bases and h = height
here, we are given the area, the length of one base and the height
we want to find the other base length
we can do this by plugging in what we are given and then solving for the unknown variable
first lets define our known variables
Area (A) = 42 , height (h) = 4 and length of one of the bases (a) = 9
we then plug this into the formula and solve for b, the other base length
recall formula : [tex]A = \frac{a+b}{2} h[/tex]
A = 42 , h = 4 , a = 9
[tex]42 = \frac{9+b}{2} 4[/tex]
now solve for b
divide both sides by 4
[tex]10.5=\frac{9+b}{2}[/tex]
multiply both sides by 2
21 = 9 + b
subtract 9 from both sides
12 = b
the other base length is 12

Answer:
f(3x) - 2g(x+1) = 12x - 5
Step-by-step explanation:
You've got f[g(x)] and g[f(x)] correct
However, f(3x) means substitute 3x for x in f(x):
f(3x) = 2(3x) - 3
⇒ f(3x) = 6x - 3
2g(x+1) = 2[4 - 3(x + 1)]
⇒ 2g(x+1) = 2[4 - 3x -3]
⇒ 2g(x+1) = 2[1 - 3x]
⇒ 2g(x+1) = 2 - 6x
f(3x) - 2g(x+1) = (6x - 3) - (2 - 6x)
⇒ f(3x) - 2g(x+1) = 12x - 5

Write an explicit equation for the sequence based on the graph at right.
Answers
Answer:
[tex]t(n)=12 \cdot 3^{n-1}[/tex]
Step-by-step explanation:
From inspection, the points on the graph are:
(1, 12)(2, 36)(3, 108)Therefore, as terms of a sequence:
[tex]t_1=12\\\\t_2=36\\\\t_3=108[/tex]
The difference between the y-coordinates is not equal, therefore the sequence is geometric.
Geometric sequence formula: [tex]t_n=t_1r^{n-1}[/tex]
As [tex]t_1=12 \implies t_n=12r^{n-1}[/tex]
To find r, divide one term by the previous term:
[tex]r=\dfrac{t_3}{t_2}=\dfrac{108}{36}=3[/tex]
Therefore, geometric sequence formula: [tex]t_n=12 \cdot 3^{n-1}[/tex]

Answers
Answer:
A.
C.
Step-by-step explanation:
A. When adding a negative number to a positive, you subtract. 2.3 - 2.3 will equal 0.
B. When adding two negative numbers, you get an even smaller negative number. (-3.7) + (-4.1) = -7.8
C. When subtracting a negative number, the two negative signs become a positive. -12/4 is equal to 3. -2.6 + 3 is 0.4, which is positive.
D. 5/2 is the same as 2.5. If you subtract 2.5 from 2.5, you will get 0, which is not negative.
E. Two negative signs make a positive, so 72 + 100 is positive, not negative.

Rationalise the denominator
Answers
Answer:
30+12(square root of 5)
Step-by-step explanation:
Answer:
30 + 12[tex]\sqrt{5}[/tex]
Step-by-step explanation:
To rationalise the denominator, multiply the numerator and denominator by the conjugate of the denominator.
The conjugate of 2[tex]\sqrt{5}[/tex] - 4 is 2[tex]\sqrt{5}[/tex] + 4 , then
[tex]\frac{12\sqrt{5}(2\sqrt{5}+4) }{(2\sqrt{5}-4)(2\sqrt{5}+4) }[/tex] ← expand denominator using FOIL
= [tex]\frac{120+48\sqrt{5} }{20-16}[/tex]
= [tex]\frac{120+48\sqrt{5} }{4}[/tex] ( divide each term on numerator by 4 )
= 30 + 12[tex]\sqrt{5}[/tex]

TBH, i am not sure what im doing. Here is a pic of the question.
Answers
Answer:
7
Step-by-step explanation:
The order of operations tells you to start any evaluation by looking at the innermost set of parentheses first.
Here, that means your first step is to find the value of h(-3). You do that by finding the input (x) value -3 in the table for h(x), and locating the corresponding output, h(x), which is 2.
Now, the problem becomes evaluating g(2).
You do the same thing for that function: locate the input x=2 in the table for g(x) and find the corresponding output: 7.
Now, you know ...
g(h(-3)) = g(2) = 7
