Answer:

x=1

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's solve the question

5(2x-8)+15=-15

Bracket first

10x-40+15=-15

We will have to solve the question further

10x-25=-15

Add 25 to both sides

10x=10

Let's make x the subject of formula by dividing both sides by 10

x=1

Therefore x is 1

Answer:

x = 1

Step-by-step explanation:

5(2x - 8) + 15 = -15

Subtract 15 both sides

5(2x - 8) = -30

Divide both sides by 5

2x - 8 = -6

Add 8 both sides

2x = 2

Divide both sides by 2

x = 1

Does anyone know how to do this? please help me
Elis [28]
On the x column, you would write 1, 2, 3, 4, and so on. Then, in the y box, you plug in that number into the equation. Write your answer in the y column. 

For example, if x = 1, then 1^2 + 2 - 8 = - 5. 
If x = 1, y= -5

A line is perpendicular to y = - x - 2 and intersects the point (-5, 10)
Lady_Fox [76]

Answer:

y = x + 15

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = - x - 2. Its slope is -1. A line perpendicular to this will have a slope of 1.

Plug this value (1) into your standard point-slope equation of y = mx + b.

y = 1x + b or y = x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-5, 10). Plug in the x and y values into the x and y of the standard equation.

10 = (-5) + b

Simplify.

10 = -5 + b

Now, add 5 to both sides to isolate b.

15 = b

Plug this into your standard equation.

y = x + 15

This equation is perpendicular to your given equation (y = -x - 2) and contains point (-5, 10)

Hope this helps!
