Answer:

x = - 10, x = 6

Step-by-step explanation:

Given

(x + 2)² = 64 ( take the square root of both sides )

x + 2 = ± \sqrt{64} = ± 8 ( subtract 2 from both sides )

x = - 2 ± 8

Thus

x = - 2 - 8 = - 10

x = - 2 + 8 = 6

Write the points (-3,5) and (1,1) in slope-intercept form
Jobisdone [24]
Y=mx+b
m=slope
b=yint

find slope
slope between (x1,y1) and (x2,y2) is (y1-y2)/(x1-x2)

given
(-3,5) and (1,1)
slope=(5-1)/(-3-1)=4/-4=-1

y=-1x+b
find b
when x=1, then y=1
1=-1(1)+b
1=-1+b
add 1
2=b

Tony is trying to find the solution of the system 2x - 4y +12 using elimination 3x + 4y = 48 He wrote these steps to solve the p
kobusy [5.1K]

Answer: Solution: (12, 3)

Step-by-step explanation:

2x - 4y = 12

3x + 4y = 48

Add both equations

5x = 60

Divide both sides by 5

x = 12

We can use the value of x to find y

3x + 4y = 48

3 (12) + 4y = 48

36 + 4y = 48

Subtract 36 from both sides

4y = 12

Divide both sides by 4

y = 3

Solution: (12, 3)
