Answer:
x = 12
Step-by-step explanation:
Given
4(x - 5) = 8x + 4 - 6x ← distribute left side and simplify right side
4x - 20 = 2x + 4 ( subtract 2x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
The value of x is -2 when f(x) = 0
Step-by-step explanation:
In any function f(x) = y
- x is the input
- y is the output
- If f(x) = 2 x + 3, then f(a) = b means when you substitute x by a the value of y = b
∵ f(x) = x³ + 8
To find value of x when f(x) = 0, substitute f(x) in the equation by
0 and solve the equation to find the value of x
∵ f(x) = 0
∴ 0 = x³ + 8
- Subtract 8 from both sides
∴ -8 = x³
- Take ∛ for both sides
∵ ![\sqrt[3]{x}=x](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%3Dx)
∵ ![\sqrt[3]{-8}=-2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-8%7D%3D-2)
∴ x = -2
The value of x is -2 when f(x) = 0

Answer:
It is an exponential function.
Initial value is - 1.8 and the base is 6.
Step-by-step explanation:
The function is given by
and it is an exponential function as the general form of an exponential function is
.
Here, if we put x = 0, the function becomes
.
Therefore, the initial value of the function is - 1.8.
In the general equation of exponential function
, b is called the base and x is the exponent.
Therefore, in our case the base of the function
is 6. (Answer)

you will need 1 more truck to hold 160 dogs
Answer:
152 degrees
Step-by-step explanation:
CF is a straight line, which means it equals 180 degrees. But FXE is an angle of 28 degrees so you subtract 180 from 28 to get 152 degrees.
