If g(x) = -4x + 5, find g(-3x).
nignag [31]
Answer: 12x + 5

Explanation:

g(x) corresponds to x, so you plug -3x into x. That equals -4(-3x) + 5. Multiply to get 12x + 5. Because you can’t add a number with a variable to a whole number, that’s your answer. Hope this helps!

If y = 5x - 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?
anastassius [24]

Answer: B. {[-1,-8),0,-3),(3,12) if im wrong sowwy

Step-by-step explanation: One simple way to solve this is that 0 = B

The formula you use in order to solve this is y= mx+b

                                                                       y= 5x-3

As we know the -3 is b and 0 is always equal to -3 C is the only choice with 0 and -3 and in x is o and y is -3 the input is 0 and the ouput is -3

x is always and input while as y is always an output.

2(4x+3)=10x-2<br> Anyone know how to work this out? <br> Working out needed
Step2247 [10]

Answer:

x = 4

Step-by-step explanation:

1. expand.

8x + 6 = 10x - 2

2. Subtract 8x from both sides.

6 = 10x - 2 - 8x

3. simplify 10x - 2 - 8x to 2x - 2.

6 = 2x - 2

4. Add 2 to both sides.

6 + 2 = 2x

5. Simplify 6+2 to 8.

8 = 2x

6. Divide both sides by 2.

\frac{8}{2}  = x

7. Simplify 8/2 to 4.

4 = x

8. switch sides.

x = 4

Therefor, rhe answer is x=4
