Umm, surface area of a cube = 6e^2 (six edge square) which is 6(3)sqaure = 54
answer:
21 + 3x (you would not put the x again since it is already given)
step-by-step explanation:
- we have to distribute 3 to the expression in the parenthesis
3 (7 + x)
= 21 + 3x
- this will be the expression once we distribute
Use substitution
Plug in -5x for y in the second equation
x + 3(-5x) = 28
x - 15x = 28
-14x = 28, x = -2
Now plug in -2 for x in first equation
Y = -5(-2) = 10
Solution: D. (-2, 10)
Answer:
x=3
Step-by-step explanation:
A function assigns the values. The function of the given graph is y=3(4)ˣ, thus, the correct option is C.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
The complete question is:
If the parent function is y = 4ˣ, which is the function of the graph?
y = −2(4)ˣ
y = −3(4)ˣ
y = 3(4)ˣ
y = 2(4)ˣ
Since the graph intersect the y-axis at 3, and the parent function of the function is y=4ˣ, therefore, we can write,
y = A(4)ˣ
3 = A(4)⁰
3 = A × 1
A = 3
Hence, the function of the given graph is y=3(4)ˣ, thus, the correct option is C.
