Answer:
I'm guessing it would be 48⁰ since it looks like I was 90⁰ so 90⁰ minus 42⁰ is 48⁰ sorry if its wrong brain is having a brain fart
Answer:
(x,y)=-(1,1)
Step-by-step explanation:
-2x=8-6y (divide by -2)
=> x=-4+3y
-15x=21-6y (divide by -3 for simplicity)
=>5x=-7+2y
We know that x=-4+3y, insert this into expression "5x=-7+2y"
5(-4+3y)=-7+2y
-20+15y=-7+2y
15y-2y=20-7
13y=13
y=1
Since x=-4+3y we can find x by using y=-1
x=-4+3(1)
x=-1
Answer: y = (x +2)² + 5
<u>Step-by-step explanation:</u>
y = a(x - h)² + k <em>where "a" is the leading coefficient and (h, k) is the vertex</em>
Since we don't know "a", we need to plug in the point (x, y) and the vertex (h, k) to solve for "a": (x, y) = (0, 9) and (h, k) = (-2, 5)
y = a(x - h)² + k
9 = a(0 - (-2))² + 5
9 = a(0 + 2)² + 5
9 = a(2)² + 5
<u>-5 </u> <u> -5 </u>
4 = a(4)
<u>÷4 </u> <u> ÷4 </u>
1 = a
Next, plug in "a" and the vertex (h, k):
y = a(x - h)² + k
y = 1(x +2)² + 5
y = (x +2)² + 5
