What is the slope and y-intercept of y+3= -1/3

bazaltina [42]

Assuming this is written correctly, with no x in the equation, we just solve for y:

y = -3 - 1/3 = -10/3 = 0 x - 10/3

That's slope-intercept form.

Answer: Slope 0, y-intercept -10/3

guajiro [1.7K]

Answer:

932.58 in^3

Step-by-step explanation:

radius = 9 inches

height = 11 inches

Volume = ?

$V= \frac{1}{3} \pi r^2 h\\\\V= \frac{1}{3} \times 3.14\times 9^2\times 11\\\\V = \frac{1}{3} \times 3.14\times 81\times 11\\\\V= \frac{2797.74}{3} \\\\V = 932.58\:in^3$

Ray Of Light [21]

Answer:

π =14 cm

Step-by-step explanation:

Given:

circumference of a circle =616 cm

pie(π)=22/7

circumference of a circle=πr^2

616=22/7 *r^2

616*7/22 =r^2

4312/22 =r^2

196=r^2

$\sqrt{196}$ =r
