Answer:

(−2, 3), because both lines pass through this point

Step-by-step explanation:

The meaning of "solution to the system of equations" is that both lines intersect at the solution point. That is, they both pass through that point.

Answer:

(−2, 3), because both lines pass through this point

Step-by-step explanation:

Line C: y = x + 5  

Line D: y = −2x − 1

Substitute x+5 for y in second equation

x + 5 = -2x -1

add 2x on both sides

3x + 5= -1

subtract 5 from both sides'

3x = -6

divide both sides by 3

x= -2

Now plug in -2 for x in y=x+5

y=-2+5= 3

so x= -2, y= 3

both lines satisfies the point (-2,3) (intersection point)

(−2, 3), because both lines pass through this point

There are 165 laptops and desktop computers in a lab. There are 9 more laptops than desktop computers. What is the total number
Alina [70]

Answer:

87

Step-by-step explanation:

Let d = number of desktops.

Let a = number of laptops.

a + d = 165

a = d + 9

d = a - 9

a + d = 165

a + a - 9 = 165

2a - 9 = 165

2a = 174

a = 87

Answer: 87

Solve 6x^2 - 42 = 0 for the exact values of x
GREYUIT [131]

Answer:

The values of x are

x=-\sqrt{7} , x=\sqrt{7}

Step-by-step explanation:

we have

6x^{2}-42=0

Solve for x

Adds 42 both sides

6x^{2}-42+42=0+42

6x^{2}=42

Divide by 6 both sides

6x^{2}/6=42/6

simplify

x^2=7

square root both sides

x=\pm\sqrt{7}

therefore

The values of x are

x=-\sqrt{7} , x=\sqrt{7}
