Answer:
y=9-7x
If x= -1, y=16
If x= 0, y=9
If x=2, y= -5
Step-by-step explanation:
Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.
y+7x=9
-7x -7x ---> y=9-7x
The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.
y=9-7(-1) ----> y=16
y=9-7(0) ----> y=9
y=9-7(2) ----> y=-5
3 possible solutions.
The reason is because of the degree, which is 3
Answer:
Step-by-step explanation:
The volume of a sphere is as follows: (4/3) * (pi) * (radius cubed)
To solve this problem, we can substitute the given value for the radius and for pi.
Volume = (4/3) * (3.14) * (2.197)
Volume = 9.1981...
Answer:
V = 825
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
The radius is 1/2 d = 1/2 (10) =5
Using 3 for pi
V = 3 ( 5)^2 * 11
V = 825
Answer:
see below
Step-by-step explanation:
7 x 13 (split 13 into 10 + 3)
= 7 x ( 10 + 3) (expand parentheses by distributive property)
= (7 x 10) + (7 x 3)
= 70 + 21
= 91
