Answer:

- 22.5

Step-by-step explanation:

Substitute x = 3 into f(x) and x = 16 into h(x) , then

$\frac{1}{2}$ g(3) - h(16)

= $\frac{1}{2}$ × - 3(3)² - (2 $\sqrt{16}$ + 1)

= $\frac{1}{2}$ × - 3(9) - (2(4) + 1)

= $\frac{1}{2}$ × - 27 - (8 + 1)

= - 13.5 - 9

= - 22.5

Answer:

y = 5/4x + 1

Step-by-step explanation:

4x + 5y = 5

5y = -4x + 5

y = -4/5x + 1

Perpendicular slope: 5/4

(-4, -4)

Slope-intercept:

y - y1 = m(x - x1)

y + 4 = 5/4(x + 4)

y + 4 = 5/4x + 5

y = 5/4x + 1

What is a coefficient

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression. In the latter case, the variables appearing in the coefficients are often called parameters, and must be clearly distinguished from the other variables
