If AB=AC then It is an isocoles triangle. Because of this, Angle ABC=ACB, meaning they are both 60°. This means that Angle BAC is also 60°. Becasue of circle theorms, the angle BOC=2BAC so angle BOC=120°

Find the equation of the line through the points (-2,5) and (3,-10). Give your answer in slope-intercept form.

Brilliant_brown [7]

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-10 - 5}{3 - (-2)} = \frac{-15}{3 + 2} = \frac{-15}{5} = -3$

y - y₁ = m(x - x₁)
y - 5 = -3(x - (-2))
y - 5 = -3(x + 2)
y - 5 = -3(x) - 3(2)
y - 5 = -3x - 6
+ 5 + 5
y = -3x - 1

Answer:

a. 405

b. -2

c. 5

d. 43

Step-by-step explanation:

I don't like doing arithmetic any more than you do, so I let a calculator do it for me. A spreadsheet works well for this, too. The function values are shown in the attachment.

Put the function argument where the variable is and do the arithmetic.

a. h(4) = 5·3^4 = 405

b. d(2) = 7 -9(2 -1) = -2

c. h(0) = 5·3^0 = 5

d. d(-3) = 7 -9(-3 -1) = 43
