Which system of linear equations has exactly one solution? 2y = 10x + 4

y = 5x - 2

y = 2x - 3

2y = x - 12

y = 8x + 3

y = 8x + 7

15y = 30x + 90

y = 2x + 6

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

$450 i think. hope this ☺

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

sweetheart, there isn't a cube below.
