C.) 2 is the right answer
Step-by-step explanation:
Given
-15(x-__)=25
We can see in the next step
We can check by substituting each option one by one
So,
A.) -30
We can see that by putting -30 we don't get the expression given in the picture so it is not the right answer.
B.) -2
We can see that by putting -2 we don't get the expression given in the picture so it is not the right answer.
C.) 2
We get the same expression by putting 2 in the blank so it is the right answer.
Hence,
C.) 2 is the right answer

We know that
[the area of the root]=4*[area of one lateral triangle side]
area of one lateral triangle side=b*h/2
b=10 ft
h=9.4 ft
area of one lateral triangle side=10*9.4/2-----> 47 ft²
[the area of the root]=4*[47]-------> 188 ft²
the answer is
the area of the root is 188 ft²
Answer:
Therefore the y-intercept of f(x) is equal to the y-intercept of g(x) ....
Step-by-step explanation:
For the given function f(x) = −3(1.02)^x
The y-intercept can be determined when x = 0
f(0)= -3(1.02)^0
f(0)= -3(1)
f(x)= -3
f(x) has a y-intercept at (0,-3)
g(x) has a y intercept at (0, -3)
Therefore the y-intercept of f(x) is equal to the y-intercept of g(x) ....
Answer:
x = - 2 ±
Step-by-step explanation:
To solve the equation using the method of completing the square.
Given
x² + 4x - 7 = 0 ( add 7 to both sides )
x² + 4x = 7
add ( half the coefficient of the x- term )² to both sides
x² + 2(2) x + 4 = 7 + 4
(x + 2)² = 11 ( take the square root of both sides )
x + 2 = ± ( subtract 2 from both sides )
x = - 2 ± ← exact solution
