Answer:

x=1, x=-6

Step-by-step explanation:

x^2+5x-6=0 can be reduced to (x+6)(x-1)=0

we now have x+6=0 and x-1=0

solve by subtracting 6 from each side in the first equation and adding 1 to each side in the second.

x=1, x=-6

Answer: option C is the correct answer

Step-by-step explanation:

The system of linear equations is

10x + 7y = 12 - - - - - - - 1

8x + 7y = 18 - - - - - - - 2

Since the coefficient of y is the same in equation 1 and equation 2, we will eliminate y by subtracting equation 2 from equation 1, it becomes

10x - 8x + 7y - 7y = 12 - 18

2x = -6

x = - 6/2 = - 3

Substituting x = - 3 into equation 1, it becomes

10×-3 + 7y = 12

-30 + 7y = 12

Let the constants be on the right hand side and the term containing y be on the left hand side. It becomes

7y = 12 + 30

7y = 42

y = 42/7

y = 6

Please help hard math
Korvikt [17]

The correct answer is a.

Inside the function it says x+2, and a +2 means it is to the left (direction is opposite of the sign)

The 3 on the outside of the function shows how the steepness, or slope will change. The first is correct because slope is rise over run, and if you go from one point to another, you'll see that it is up 3 and over 1, or 3/1, or 3.

Solve for z. z−49−13=59 Enter your answer in the box. z=
REY [17]

Hello there!

Solve for z.

z-49-13=59

Explanation

↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by the numbers.

-49-13=-62

z-62=59

Then you add by 62 from both sides of the equation.

z-62+62=59+62

Simplify it should be the correct answer.

z=121

Answer⇒⇒⇒⇒z=121

Hope this helps!
