8(1+5x) + 5 = 13 + 5x

Mathematics
2 answers:
Lapatulllka [165]3 years ago
5 0

8(1+5x) + 5 = 13 + 5x

multiply the bracket by 8

(8)(1)=8

(8)(5x)=40x

8+40x+5=13+5x

8+5+40x=13+5x

13+40x=13+5x

move 5x to the other side

sign changes from +5x to -5x

13+40x-5x=13+5x-5x ( combine like terms)

13+35x=13

move 13 to the right side

13-13+35x=13-13

35x=0

divide both sides by 35 to get x by itself

35x/35=0/35

Answer:

x=0

A 5–foot string of lights will be attached to the top of a 4–foot pole for a holiday display. How many feet from the base of the
wel

Answer:

3

Step-by-step explanation:

The lights and pole form a right triangle. The question gives the hypotenuse as 5 and one side length as 4.

Use the Pythagorean theorem: a^2+b^2=c^2.

Plug in what you are given: 4^2+b^2=5^2

16+b^2=25

b^2=9

b = 3

Or you could recognize that it was a pythagorean triple: 3, 4, 5

If we changed the –0.14 to a 2 in the equation, what would happen to the graph?
MatroZZZ [7]

If -0.14 is changed to 2, the graph would become a positive graph, or it would be steeper, because it has a positive slope

The equation of the graph is given as:

y = -0.14x + 3

The above equation is a linear equation, which is represented as:

y =mx + c

Where m represents the slope of the linear equation.

By comparison, we have:

m = -0.14

i.e. the slope of the equation y = -0.14x + 3 is -0.14

When -0.14 is replaced with 2, the equation becomes

y = 2x + 3

And the slope of the new equation y = 2x + 3 is

m =2

2 is greater than -0.14, and 2 is positive.

This means that the graph would become a positive graph, or it would be steeper, because it has a positive slope

This needs to be answered for a number line <br><br> -9=4x+3
Galina-37 [17]

Answer:

X=-3

Step-by-step explanation:

To find the unknown variable: X, we need to see how mich 4x equals to. to do this, we must first subtract 3 from both sides of the equation. The left side will be left with -12, and the right side will be left with 4x. This means:

-12=4x So...

x=-3

To check if this is right, you can subsitute this back into the equation.

4 times -3= -12. -12=3=-9
