Mathematics

1 answer:

Rashid [163]3 years ago

3 0

Answer:

Step-by-step explanation:

Given

y = x + 7

To determine if (7, 0) is a solution of the equation

Substitute x = 7 into the equation and if the result is 0 then it is a solution

y = 7 + 7 = 14 ≠ 0

Hence (7, 0) is not a solution

Simplify 5x + 2(x - 3) = -2(x - 1)

Kruka [31]

Answer:

x=8/9

Step-by-step explanation:

5x+2(x-3)=-2(x-1)

1) Distribute 2 to x and -3:

5x+2x-6=-2(x-1)

2) Distribute -2 to x and -1:

5x+2x-6=-2x+2

3) Combine alike terms:

7x-6=-2x+2

4) Add 2x to both sides:

9x-6=2

5) Add 6 to both sides:

9x=8

6) Divide both sides by 9:

x=8/9

The difference between the squares of two consecutive numbers is 23. what are the two numbers?

Ksju [112]

(x+1)^2-x^2=23

x^2+2x+1-x^2=23

2x+1=23

2x=22

x=11

11^2 = 121

x+1 =12

12^2=144

144-121 = 23
