Answer:

1. Calculate the slope from 2 points.

2. Substitute either point into the equation.

3.Solve for b, which is the y-intercept of the line.

4. Substitute b, -1, into the equation from step 2.

Step-by-step explanation:

I gave you one extra than what you expected, if thats ok.

Hope this helps : )

$|\Omega|=(\text{the area of the triangle})=\dfrac{a^2\sqrt3}{4}=\dfrac{3^2\sqrt3}{4}=\dfrac{9\sqrt3}{4}\\|A|=(\text{the area of the sector})=\dfrac{\alpha\pi r^2}{360}=\dfrac{60\pi \cdot 1^2}{360}=\dfrac{\pi}{6}\\\\\\P(A)=\dfrac{\dfrac{\pi}{6}}{\dfrac{9\sqrt3}{4}}\\\\P(A)=\dfrac{\pi}{6}\cdot\dfrac{4}{9\sqrt3}\\\\P(A)=\dfrac{2\pi}{27\sqrt3}\\\\P(A)=\dfrac{2\pi\sqrt3}{27\cdot3}\\\\P(A)=\dfrac{2\pi\sqrt3}{81}\approx13.4\%$

Find the slope of the line 8x – 4y = 8\ (hint: find 2 points; then use the slope formula)

Vera_Pavlovna [14]

8x - 4y = 8

-4y = -8x + 8

y = -8x/-4 + 8/-4

y = 2x - 2, comparing to y = mx + c, slope m = 2

Slope = 2.

G(x) = 6x^2-7<br> Find g(x+2)

Ahat [919]

Answer:

= 6x² + 24x + 17

Step-by-step explanation:

g(x+2) = 6(x+2)² -7

= 6(x² + 4x + 4) - 7

= 6x² + 24x + 24 - 7

= 6x² + 24x + 17

Evaluate g(3) if g(x) = 2x + 1.<br> 0 1<br> 07<br> 24

evablogger [386]

Answer:

g(3) = 7

Step-by-step explanation:

g(3) means to substitute "x" for 3.

Change any "x" in the function to 3. Then solve.

Take the function

g(x) = 2x + 1

Substitute x = 3

g(3) = 2(3) + 1

Solve with BEDMAS order (brackets, exponents, division, multiplication, addition, subtraction).

g(3) = 2(3) + 1 Multiply first

g(3) = 6 + 1 Add

g(3) = 7 Answer
