Algebra help please!!!!!
attashe74 [19]
Y = 3x - 6....to find the x int, sub in 0 for y and solve for x
0 = 3x - 6
-3x = -6
x = -6/-3
x = 2......so the x int here is 2

y = 3x - 6...when the slope is decreased by 2...
y = x - 6...this is the slope decreased by 2
0 = x - 6
-x = -6
x = 6.....so the x int here is 6

so ur answer is : the x int increases

Explain why two obtuse angles cannot be supplementary to another.
Nuetrik [128]
It's impossible. Supplements need to add up to 180 degrees, and in order to be obtuse, the angles would both need to be larger than 90 degrees.

Point A is at (-5, -4) and point M is at (0, -3.5).
ludmilkaskok [199]

Answer:

The coordinates of point B are (5,-3)

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

In this problem

Point A is at (-5, -4) and point M is at (0, -3.5)

point\ A=(x_1,y_1)\\point\ B=(x_2,y_2)\\point\ M=(0,-3.5)

substitute in the formula

(0,-3.5)=(\frac{-5+x_2}{2},\frac{-4+y_2}{2})

so

Solve for x_2

0=\frac{-5+x2}{2}\\x_2=5

Solve for y_2

-3.5=\frac{-4+y_2}{2}\\-7=-4+y_2\\y_2=-3

therefore

The coordinates of point B are (5,-3)

While building a snowman, a large snowball is created so that the radius is changing at the rate of 5 inches per hour. How fast
diamong [38]

Answer:

2000π in³/s

or 6283.2 in³/s

Step-by-step explanation:

dr/dt = 5  

volume of sphere is given as

v = (4/3)(π)r³

differentitate wrt r

dv/dr = 3×4/3 ×π×r²

dv/dr = 4πr²

put r = 10

dv/dr = 4π(10)²

dv/dr = 400π

by chain rule

dv/dt = dv/dr ×dr/dt

dv/dt = 400π× 5

dv/dt = 2000π in³/s

or dv/dt =6283.2 in³/s
