I think it is A, it could be A or D for sure not B or C. But when you think about it it’s probably A.

Answer: B

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

 2x - 3y =  -7   →   2(2x - 3y = -7)   →   4x - 6y = -14

-4x + 6y = -10  →   1(-4x + 6y = -10) → <u>-4x + 6y</u> = <u>-10 </u>

                                                                    0  = -24

                                                                     FALSE

Since this makes a false statement, there are no solutions

Help me plss, number 2.​
Gnesinka [82]

Answer:

At (-2,0) gradient is -4 ; At (2,0) gradient is 4

Step-by-step explanation:

For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).

y = x^2 - 4

y' = 2x

The function y = x^2 - 4 cross the x-axis when:

y = x^2 - 4

0 = x^2 - 4

4 = x^2

2 +/- = x

Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).

The gradient at these points are as follows:

y' = 2(-2) = -4

y' = 2(2) = 4

Cheers.

swat32

Answer:

x = 25

Step-by-step explanation:

Given

4x + 50 = 150 ( subtract 50 from both sides )

4x = 100 ( divide both sides by 4 )

x = 25
