I need help ASAP please

(2,0)

(-3,-5)

x = 2,-3

Step-by-step explanation:

y = 4-x^2

x-y =2

Substitute the first equation into the second for y

x - (4-x^2) =2

Distribute

x - 4 +x^2 =2

Subtract 2 from each side

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

x^2 +x -6 = 0

Factor

(x-2) (x+3) =0

Using the zero product property

x-2=0     x+3=0

x=2         x=-3

Now find y for each x

x=2

y =4-x^2 = 4 -2^2 =4-4=0

(2,0)

x=-3

y = 4 - (-3)^2 =4 -9 = -5

(-3,-5)

D. x = 2, -3

Step-by-step explanation:

y = 4 - x²

x - y = 2

x - 4 + x² = 2

x² + x - 6 = 0

x² + 3x - 2x - 6 = 0

x(x + 3) - 2(x + 3) = 0

(x - 2)(x + 3) = 0

x = 2, -3

x = 2, y = 4 - 2² = 0

x = -3, y = 4 - (-3)² = -5

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
