Answer: B. No
Step-by-step explanation: Let's think of the variable x as apples. If there are 7 apples and then you added 1 other something, that would be different than having 1 apple and adding 7 other somethings. The equations would have a different amount of somethings and apples.
Answer:
x = 9 ft
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is x
4069.44 = pi x^2 16
Divide each side by 16 pi
4069.44 / 16 pi = x^2
Using 3.14 for pi
81 = x^2
Take the square root of each side
sqrt(81) = sqrt(x^2)
x = 9
Answer:
yes!!!
Step-by-step explanation:
Short explanation. The same y value can be true for many "exs". But the same x value can only have ONE y value to define a function. So if you draw y = 0.5 across that graph that you have given us, you get many x values that have 0.5 as a y value.
If on the other hand, you draw a line of x = 1, there is only 1 value that y has and that is zero.
This is a function.
Answer:
30
Step-by-step explanation:
7/5 = 42/x
You get 42 by doing 7x6 and then 5x6 to get 30.
Answer:
y = -2/3x - 3
Step-by-step explanation:
y = mx + b
m = slope
(-3,-1) = (x,y)
<em>Plus in the coordinates</em>
-1 = -2/3(-3) + b
<em>negative times negative = positive</em>
-2/3 * -3 = 2
-1 = 2 +b
<em>Use inverse operations</em>
-2 --2
-3 = b
y = -2/3x - 3
