y-4= }(x-7)
y-7= (x - 4)
y+7= (x+4)

Answer:

a

The sale was for a 43% decrease.

Step-by-step explanation:

The computation of the percent off of the coat during the sale is shown below:

Regular price is $35.25

And, in the sale the price is $19.99

So, the percent off would be

= ($35.25 - $19.99) ÷ ($19.99)

= 43% decrease

hence, the percent off of the coat during the sale is 43% decrease

Therefore the correct option is a.

And, all the other options are incorrect

Answer:

4(3^2)

3^2=9

4(9)= 36

Answer:

4(3•3)

4(9)

36

Step-by-step explanation:

3 to the second power is equal to 3•3, which is equal to 9

Then you do 4 times 9, equals to 36

Answer:

(y2 - y1)/(x2-x1)

Step-by-step explanation:

if you have 2 points (x1,x2) and (y1,y2), just plug it in the formula for slope m

m = (y2 - y1)/(x2-x1)

Answer:

13 dollars

Step-by-step explanation

30 percent - 0.3

0.3 times 19 = 13

Answer:

$13.30

Step-by-step explanation:

This problem is asking you to find thirty percent of nineteen. So, after setting up the proportion and doing the cross multiplying, I found that the amount of the discount is five dollars and seventy cents.

Now that I have the discount price, I just needed to subtract that from the regular price. Nineteen dollars minus five dollars and seventy cents is thirteen dollars and thirty cents. The cost of the shirt on sale is thirteen dollars and thirty cents.

What is 30% of 19? ?/ 19 = 30/100  19 x 30 = 570 ÷100= 5.7. The discount is $5.70 $19.00-$5.70= $13.30. so the sale price is $13.30

Answer:

The radius of the clock is 7.72 meters

Step-by-step explanation:

Here, we want to calculate the radius of a clock which has a circumference of 48.5 m

Mathematically;

Circumference C = 2 * pi * r

48.5 = 2 * 22/7 * r

7 * 48.5 = 44r

r = (7 * 48.5)/44

r = 7.72 meters

Answer:

B is correct

Step-by-step explanation: an infinite number of solutions means a coincident line...it is the same line

3y = 2x - 9...divide by 3

y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions

Answer:

the answer is B).

Step-by-step explanation:

Slope is x2-y2/ x1-y1

So, its 6-10/1-2

or, -4/-1

Or 4.

Hope this helps you!

#Team Rainbows.

Answer:

4.

Step-by-step explanation:

The slope = (difference in y coordinates) / (corresponding difference in the x coordinates)

= (10-6)/ (2-1)

= 4 / 1

= 4.

sorry i forgot to add a couple numbers i was in a rush

Explanation:

Choice A combines to 11x since the 8+3 simplifies to 11.

Choice D is a very similar story. Think of having 8 boxes, which we denote in shorthand as 8x. Then adding on 3 more boxes leads to adding on 3x. Having 8 boxes plus another 3 boxes gives 8+3 = 11 boxes total. So that's why 8x+3x = 11x. Alternatively, we can factor out the x to say 8x+3x = (8+3)x.

This shows choices A,C, and D are equivalent expressions. Choice B is the odd one out.

Answer:

Hey, ill do like 2 and you can do the rest

percent decrease or change is

new-old over old

So like #1

1) 60 is old, 48 is new

so 48-60=-12

now over old which is 60

-12/60

-1/5

20 percent decrease

2) 180 is old, 108 is new

108-180=-72

-72/180

40 percent decrease

Answer:

6,371.15

Step-by-step explanation:

3.14 times 13^2 times 12

Answer:

Volume equals pi times radius to the power of 2 times height

that will be pi times 13^2 times 12= 6,367.92

radius is the 13 and you have to put it to the power of 2 and multiply it by 3.14 which is pi and multiply it by 12 and the answer is 6,367.92

Answer:

16/5 or 3 1/5 i think

Step-by-step explanation:

Answer:

x = 16/5.

As a decimal this would be x = 3.2.

Step-by-step explanation:

On the right, distribute the -1/4 to the (x - 8). Do this by multiplying -1/4 to each term in the parenthesis. Then, solve for x by combining like terms.

Answer: 1/4

Step-by-step explanation:

Answer:

x > 2

y ≥ 2

x + y ≤ 8

Step-by-step explanation:

Here, we want to write a system of equations according to the given variables

More than means, greater than

since x is the variable we want to use;

x > 2

At least 2 hours means greater than or equal to 2

That is mathematically represented as;

y ≥ 2

At most means less than or equal to

So;

x + y ≤ 8

Answer:

a(217)=638

Step-by-step explanation:

a(n) = a +(n-1)d

a=-1

d=-7+10=-4+7=3

a(n) = -10 +(n-1)3

a(217) = -10 +(217-1)3

         = -10+648

         =638

Answer:

84

Step-by-step explanation:

they are all equal sides so what you'd do is 28+28+28= 84

Answer: 56

Step-by-step explanation: It's an equilateral shape so all sides are equal, so then both angle UVS and UTS are congruent to each other. But since it's asking for the whole angle T you can just do 28+28=56 and that's your answer. Hope I'm right

Answer:

The cost of one daylily is $10 and the cost of one pot of ivy is $11

Step-by-step explanation:

To solve the question we will form a system of equations

Assume that the cost of 1 daylily is x and the cost of 1 pot of ivy is y

∵ Sumalee spent $93 on 6 daylilies and 3 pots of ivy

→ Multiply x by 6, y by 3, then add the products and equate the sum by 93

∴ 6x + 3y = 93 ⇒ (1)

∵ Scott spent $196 on 13 daylilies and 6 pots of ivy

→ Multiply x by 13, y by 6, then add the products and equate the sum by 196

∴ 13x + 6y = 196 ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (1) by -2

∵ -2(6x) + -2(3y) = -2(93)

∴ -12x - 6y = -186 ⇒ (3)

→ Add equations (2) and (3)

∵ (13x + -12x) + (6y + -6y) = (196 + - 186)

∴ x + 0 = 10

∴ x = 10

→ Substitute the value of x in equation (1) to find the value of y

∵ 6(10) + 3y = 93

∴ 60 + 3y = 93

→ Subtract 60 from both sides

∵ 60 - 60 + 3y = 93 - 60

∴ 3y = 33

→ Divide both sides by 3

∴ y = 11

∴ The cost of one daylily is $10 and the cost of one pot of ivy is $11
