Answer:

A. (0,2) and (7,23)

Step-by-step explanation:

To solve, we set both equations equal to each other (because both equations equal y).

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

x^2 - 7x = 0

x(x-7)

so the x values are 7 and 0.

Plugging x back into the linear equation (because it’s easier)

3(7) + 2 = 23

3(0) + 2 = 2

so the answers are (7, 23) and (0,2)

Can someone help me with these 4 questions asap
Anit [1.1K]

Answer:

4a.)

so the equation for this can be:

3/4 divided by 1/8

also, how many times can 1/8 go into 3/4

3/4=6/8

1/8 goes into 6/8 6 times, so 6 cupcakes out of the 8 cupcakes(or however many cupcakes there are - the problem doesn't specify that)

4b.)

3/4 ÷ 1/8

10.)

each square is 2 units wide(or long-whatever you wanna call it)

i don't really know how to explain this one, but i can just give you my answer (you can jut count up the squares along the outside of the polygon-the meaning of perimeter)

76 units

the bottom left one (i cant read the question number sorry)

1/10 of 237=

1/10*237=

237/10=

23.7

19.)

reflection pretty much means mirroring, so if you add the distance from E to the y axis and M to the y axis, you will get 10 (|-5|+|5|)

point m is in the 1st quadrant (sorry i don't really know how to explain this one either)

hope this helped!!

7 - 7(-8 + x) = -14 + 4x How do you solve for x
Lelu [443]
First thing you need to do is distributive property and that will give you
 7-56-7x=-14+4x then combine like terms which will then give you
-49-7x=-14+4x Next get your letters on the left do that by subtracting 4x which will give you -49-11x=-14. After that you will add 49 to both sides which will give you
-11x= 35. Divide by -11 to get x=3.18
