Answer:

9. 225

10. 14

Step-by-step explanation:

9.

Divide the coefficient of x by 2 and square it.

30/2 = 15

15^2 = 225

Answer: 225

10.

When you divide the middle coefficient by 2 and square it, you get the constant term (the third term). Here, the constant term is 49. 49 is the square of 7. Double 7 to get 14.

Answer: 14

This is the third time I have asked this question. Someone please answer! Brainlist IF possible. Use the graph to write a linear
Likurg_2 [28]

Answer:

Use the graph to write a linear function that relates y to x. The points lie on a line. Find the slope and y-intercept of the line. Because the line crosses the y-axis at (0, −3), the y-intercept is −3.w

Step-by-step explanation:

There are three standard forms for linear functions y = f(x):

f(x) = mx + b (The "slope-intercept" form),

y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.

Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.
