irakobra [83]3 years ago

Answer:

c. -17

Step-by-step explanation:

We have the function f(x) = -2t^2 + 1 and we need to solve for x if f(-3).

Substitute the x in the function with the x in the equation :

f(-3) = -2(-3)^2 + 1

Solve for the answer :

f(-3) = -2(9) + 1

f(-3) = -18 + 1

f(-3) = -17

Therefore, c. -17 is the answer.

Write the equation of the given line in slope-intercept form.​
gizmo_the_mogwai [7]

Answer:

y = 2x - 1

Step-by-step explanation:

Slope intercept form: y=mx+b

point a: (1, 1)

point b: (2, 3)

1. Find the slope of the equation

Equation for slope(mx): (y2- y1)/ (x2-x1)

(3-1)/(2-1)= 2

slope: 2

2. Pick any of the two point to find the "b" and plug in the coordinates of the point to find the y-intercept of the equation.

point a: y=1, x=1

y=mx+b

1=2(1) + b

b= -1

3. Plug the answers you found above into the slope-intercept form

Overall equation:

y=2x - 1
