Answer:

D. The y-intercept of the new graph would shift down 2 units.

Step-by-step explanation:

y = -9x + 3 has a y-intercept of 3 (0, 3).

y = -9x + 1 has a y-intercept of 1 (0, 1).

3 - 1 = 2

So, down two units.

Answer:

1. Equation is x - 5 = 8

x = 13

2. Equation is 4x - 4 = 10

x = 3.5

3. Equation is x/4 = 8

x = 32

4. Equation is 5x = 10

x = 2

5. Equation is x - 5 / 2 = 14

x = 33

6. Equation is 4x / 5 = 10

x = 12.5

7. Equation is 2x - 10 = 8

x = 9

8. Equation is 3x + 6 / 3 = 10

x = 8

9. Equation x + 8 / 4 = 14

x = 48

Need help ASAP. i forgot all the steps after the Area is solved with 5. or if 25pi is the right answer.

maxonik [38]

Answer:

$42.5\:\mathrm{m^2}$

Step-by-step explanation:

The area of a sector with measure $\theta$ in degrees is given by $r^2\pi\cdot\frac{\theta}{360}$ , where $r$ is the radius of the sector.

What we're given:

$r$ of 5
$\theta$ of $195^{\circ}$

Solving, we get:

$A_{sector}=5^2\pi\cdot \frac{195}{360}=13.5416666667\pi=42.5424005174\approx \boxed{42.5\:\mathrm{m^2}}$

*Notes:

units should be in square meters (area)
the problem does not say whether to round or leave answers in term of pi, so you may need to adjust the answer depending on what your teacher specifically wants
