If the parent graph f(x) = x² is changed to f(x) = 2x², the vertex of the parabola will still remain (0, 0) because whenever the equation of a parabola is in the form y = ax², the vertex will always be (0, 0).

Now if <em>a</em> is a big number, the parabola will become narrower.

So it will stretch vertically and become narrower.

Determine the intercepts of the line. − 6 x + 3 y = − 7
egoroff_w [7]

Answer:

Step-by-step explanation:

-6x + 3y = -7

to find the x intercept, sub in 0 for y and solve for x

-6x + 3y = -7

-6x + 3(0) = -7

-6x = -7

x = 7/6 <=== ur x intercept is (7/6,0)

to find the y intercept, sub in 0 for x and solve for y

-6x + 3y = -7

-6(0) + 3y = -7

3y = -7

y = -7/3 <=== ur y intercept is (0,-7/3)

Can someone please help!
romanna [79]

Answer:

The value of x is 49 and the value of AB is 90

Step-by-step explanation:

You know that AB and DE are congruent. That information is given to you.

You set the equations equal to each other and then solve.


2x - 8 = x + 38


Subtract x


x - 8 = 38


Add 8.


x = 49


Plug back into 2x - 8 to find the value of AB


2 times 49 - 8


98 - 8


90
