Answer:

the x-coordinate

Step-by-step explanation:

The slope intercept form is: y = mx + c

where m⇒ slope

c ⇒ y-intercept

(x,y) is a point on the graph the satisfy the equation representing that graph.

∴ x is the x-coordinate of a point on the line.

What is the x-value at which the graphs of y = x2 – 2x + 1 and y = x2 + 2x – 7 inter-<br> sect?

Kitty [74]

Answer:

x = 2

Step-by-step explanation:

Both equations are equal to y, so they're also equal to each other. We then set them equal to each other:

x^2 - 2x + 1 = x^2 + 2x - 7

We now do algebra to isolate x. Subtract 1 from both sides.

x^2 - 2x = x^2 + 2x - 8

Subtract 2x from both sides.

x^2 - 4x = x^2 - 8

Subtract x^2 from both sides.

-4x = -8

Divide both sides by -4.

x = 2

Erika calculated that she would spend $115 on school supplies this year. She actually spent $82.50 on school supplies. What is E

DerKrebs [107]

Answer:

Step-by-step explanation:

Percentage error is calculated by

Percentage error = (estimate-real)/real*100%=(115-82.5)/82.5*100%=28.26%

An over-estimate gives a positive error percent, and an underestimate gives a negative error.

Also, dividing by the real value makes it possible to have more than 100% error.

For example, if real cost is $50, and estimated cost is $150, then error percent is (150-50)/50*100%=200%!

C: 39.4%

Step-by-step explanation:

The formula to calculate the percent error is given by :-

Given: The estimated amount = $115

The actual amount = $ 82.50

Now, the percent of error will be given by :-

Paha777 [63]

Answer:

There are 1344 pound of sand will it take to fill the sand box

Step-by-step explanation:

* Lets explain how to solve the problem

- A bag of a certain type of sand weighs 42 pounds

- The volume of the bag is 0.5 cubic feet

- The volume of a sand box is 16 cubic feet

- We need to know how many pounds of sand will it take from the

bags to fill the sand box

- To know that we must to calculate the number of sand bags will

used to fill the sand box with sand

- The number of bags = volume of the box ÷ volume of a bag

∵ The volume of a bag is 0.5 feet³

∵ The volume of the box is 16 feet³

∵ The number of bags = volume box ÷ volume bag

∴ The number of bags = 16 ÷ 0.5 = 32

∴ The number of the bags of sand is 32

- To fill the sand box with sand we need 32 bags of sand

∵ The weight of each bag is 42 bounds

∵ The number of bags that will fill the sand box is 32

∴ The number of pounds = 32 × 42 = 1344 pounds of sand

* There are 1344 pound of sand will it take to fill the sand box

What is the slope and y-intercept in the equation y = 5x - 7?

grin007 [14]

Answer:

Slope: 5

y-intercept: -7

Step-by-step explanation:

Slope-intercept form is written as ' $y=mx+b$ ', $(x,y)$ being any point on the line, $m$ its slope, and $b$ the line's y-intercept.

$y=mx+b$

$y=5x-7$

In this equation, $m=5$ , and $b=-7$ .
