Answer: T(x) = 18x + 65

Step-by-step explanation:

T(x) = A(x) + B(x)

T(x) = 10x + 50 + 8x + 15             [Plug in the number for A(x) and B(x)]

T(x) = 10x + 8x+ 50 + 15

T(x) = 18x + 65

What is the equation of a circle with center (-3,-5) and radius 4?
kobusy [5.1K]

Answer:   D) (x + 3)² + (y + 5)²  = 16

<u>Step-by-step explanation:</u>

The equation of a circle is: (x - h)² + (y - k)² = r²    

where (h, k) = center   and    r = radius

Given: (h, k) = (-3, -5)  r = 4

Equation: (x - (-3))² + (y - (-5))² = 4²

                 (x + 3)²  +  (y + 5)²  = 16

What is the output, or y-value, when you input x = 1 into the function:
Aleksandr [31]

Answer: y=-6

Step-by-step explanation:

By definition, a relation is a function if and only if each input value has one and only one output value.

For this exercise it is important to remember that thw "Input values"  are the values of the variable "x"and the "Output values"  are the values of the variable"y".

In this case you have the following function provided in the exercise:

y = x^4 - 2x^3 + x^2 + 4x - 10

Then, to solve this exercise, you need to follow these steps:

Step 1. You have to substitute x=1 into the function given.

Step 2. Finally, you must evaluate in order to find the corresponding output value (or the value of the variable "y")

You get that this is:

y = (1)^4 - 2(1)^3 + (1)^2 + 4(1) - 10\\\\y=-6

24-4x=2x<br> show your work, will mark brainliest
vladimir2022 [97]

Answer:

x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

24−4x=2x

24+−4x=2x

−4x+24=2x

Step 2: Subtract 2x from both sides.

−4x+24−2x=2x−2x

−6x+24=0

Step 3: Subtract 24 from both sides.

−6x+24−24=0−24

−6x=−24

Step 4: Divide both sides by -6.

−6x /−6  = −24 /−6

x=4
