Sub y+2 for x into second equaton

(y+2)^2+y^2+(y+2)y=49
y^2+4y+4+y^2+y^2+2y=49
3y^2+6y+4=49
minus 49 both sides
3y^2+6y-45=0
factor
3(y^2+2y-15)=0
3(y-3)(y+5)=0
set to zero
y-3=0
y=3
y+5=0
y=-5

y=3 and -5

sub back

x=y+2
x=3+2
x=5

x=y+2
x=-5+2
x=-3

the points are
(-3,-5) and (5,3)

PLEASE HELP! I WILL MARK TOU AS BRAINLEIST!
san4es73 [151]

Answer:

a.Z(-2,1)

b.Z(1,1)

c.Z(-3,2)

Step-by-step explanation:

z(-2,3)

Imagine this point on a graph.

Translate it down two units :

the x stays -2, by going down the y decreases 2 so 3-2=1

Z(-2,1)

Translate Right three units : I'm assuming that we use the answer from the first translation

Z(-2,1)

The y doesn't change this time the x increases 3 since we're moving to the right.

Z(1,1)

Translate up 1 and left 4:

Z(1,1)

by moving up one we have Z(1,2) then by moving 4 to the left we get Z(-3,2)

Hope this helps :)

Y’all what’s this I’m so confused help
Snowcat [4.5K]

Answer:

x = 66

Step-by-step explanation:

√(x - 2) + 3 = 11

Subtract 3 from both sides:  √(x - 2) = 8

Square both sides:                   x - 2 = 64

Add 2 to both sides:                      x = 66
