Write linear equation m=3 and runs through the point (9,2)

1 answer:

7 0

To solve the question, use the equation y=mx+b. Since you already know the slope (m), all you need is to find the b. Plug in the x and y from the point (9,2) and m:

2=3(9)+b
2=27+b (subtract 27 on both sides)
b=-25

The equation is y=3x-25

Answer:

AE = 60 units

Step-by-step explanation:

GE is one third the length of AE so...

GE = 1/3(AE)

20 = 1/3x

3(20) = (1/3x)3/1

60 = x

x = 60

AE = 60 units

Hi! I'm Jenny and I'm a mathematician! I'd love to help you with this problem! :)

Lets get started...

I'll write the equation out for you!

x + x(xx)

Put the value of x = 2 in the above expression we get,

2 + 2(22)

= 2 + 2(2 × 2)

= 2 + 2(4)

= 2 + 8

= 10

Answer:

C. 3x² +24

Step-by-step explanation:

Use the given function definitions and simplify.

$g(f(x))=g\left(\dfrac{1}{3}x^2+4\right)\\\\=9\left(\dfrac{1}{3}x^2+4\right)-12\\\\=3x^2+36-12\\\\\boxed{g(f(x))=3x^2+24}\qquad\textbf{matches C}$
