Jamar bought new headphones. The original price was $170, but Jamar bought the headphones when they were on sale for 30% off. What did Jamar pay for the new headphones?

Answer:

14. y = x - 6

15. [tex]y = -\frac{1}{2}x-5[/tex]

Step-by-step explanation:

Slope-intercept form is y = mx + b where:

"m" is the slope

"b" is the y-intercept

"x" and "y" are points on the graph.

For each question,

14.

Slope:

Two points are (6, 0) and (7, 1).

[tex]m= \frac{rise}{run} \\=\frac{1}{1}\\= 1[/tex]

Y-intercept:

b = -6

y = 1x - 6

We don't need to write the 1.

∴ The equation is y = x - 6

15.

Slope:

Two points are (-2, -4) and (0, -5).

[tex]m = \frac{rise}{run}\\=\frac{-1}{2}[/tex]

Y-intercept:

b = -5

∴ The equation is [tex]y = -\frac{1}{2}x - 5[/tex]

This loan of $160,000 costs Emily $26400 more than Frank.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

As given in the question,
Frank and Emily each take out a $160,000 loan for a new house. Each has to repay the loan in 20 years.
Frank's monthly payments will be $885.
Emily's monthly payments will be $995.
Difference of the total loan payment,
= 20×12[995  - 885]
= 240 × [110]
= $26400

Thus, this loan of $160,000 costs Emily $26400 more than Frank.

Answer:

Infinite solutions

Step-by-step explanation:

If we subtract 3 from both sides we get:

x = x

If we subtract x from both sides of that, we get:

0 = 0.

Well... 0 is ALWAYS equal to 0, so there is no answer that can make that statement invalid, meaning that all numbers are solutions.

Answer:

x>20

Step-by-step explanation:

given that

Marta has $500 in her bank account

Marta deposits $75

the total amount in the account after x weeks is

y=500+75x----------1

Guadalupe deposits $95 into her account each week for x weeks.

the total amount in the account after x weeks is

y=95x-----------2

equating 1 and 2 we have

500+75x=95x

solving for x we have

500=95x-75x

500=25x

x=500/25

x=20

the inequality is

x>20

Answer:

A^2+B^2=C^2

Step-by-step explanation:

You plug in the sides to A and B not C,Becuse you are trying to get C.C is called the Hypotenuse,That is what you are trying to figure out

Hope that helps

The equation correctly applies the Pythagorean Theorem is x² + 16² = 20 ².

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

Let's recall the Pythagorean theorem formula:

a² + b² = c²

Replacing by the values we have;

x² + 16² = 20 ²

Therefore, the correct answer is B.

The equation correctly applies the Pythagorean Theorem is x² + 16² = 20 ².

Answer:

a. 50x ≤ 1400 boxes

b. 25 boxes

Step-by-step explanation:

A forklift has a maximum carrying capacity of 1,400 pounds.

a. Each box at the warehouse weighs 50 pounds. Write an inequality to show the number of boxes that the forklift can hold.

Let the weight of this box be represented as x

Hence, the inequality to show the number of boxes the forklift can hold us

50 pound × x ≤ 1400 pounds

50x ≤ 1400

b. A 150-pound crate is used to hold the boxes on the forklift. What is the maximum number of boxes that the forklift can carry in the crate?.

We know already the maximum load the forky can carry is 1400

Hence, our equation is:

150 + 50x ≤ 1400

50x ≤ 1400 - 150

50x ≤ 1250

x ≤ 1250/50

x ≤ 25

The maximum number of boxes the forklift can carry in the crate is 25 boxes

Answer:

x=−12

Step-by-step explanation:

−6x+5(−2x−11)=137

Step 1: Simplify both sides of the equation.

−6x+5(−2x−11)=137

−6x+(5)(−2x)+(5)(−11)=137(Distribute)

−6x+−10x+−55=137

(−6x+−10x)+(−55)=137(Combine Like Terms)

−16x+−55=137

−16x−55=137

Step 2: Add 55 to both sides.

−16x−55+55=137+55

−16x=192

Step 3: Divide both sides by -16.

−16x/−16=192/−16

Answer:

-6x-10x-55=137

-16x-55=137

-16x=137+55

-16x=192
