Answer:
y=3x +25
Step-by-step explanation:
First calculate the slope:
m = (y1 - y2)/(x1-x2)
m = (49 - 13)/(8-(-4))
m= 36/12 = 3
so we have
y = 3x + b
subtitute a point:
49=3(8) + b
b=25
the equation is y=3x +25
Answer:
I believe it is 32
Step-by-step explanation:
I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32
Answer:
The volume of the hemisphere is 496741.6 m³
Step-by-step explanation:
The volume of an sphere is given by:
In which and r is the radius.
An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So
In this question:
. So
The volume of the hemisphere is 496741.6 m³
Answer:
g=-6, x=-1
Step-by-step explanation:
23=−4g−1
Step 1: Flip the equation.
−4g−1=23
Step 2: Add 1 to both sides
−4g−1+1=23+1
−4g=24
Step 3: Divide both sides by -4
−4/-4g
=24/-4
g=-6
--------------------------------------------------------------------------------------------------------------
13=−4x+9
Step 1: Flip the equation
−4x+9=13
Step 2: Subtract 9 from both sides
−4x+9−9=13−9
−4x=4
Step 3: Divide both sides by -4
−4x/-4=
4/-4
x=−1
