Your answer is D){28, 42, 56, 70, 84}

To answer this question you just have to make sure the amount he pays is a multiple of 7.If you know you times table then this should be easy

Times table of 7:

7,14,21,28,35,42,49,55,63,70,77,84.

Now you just need to find an answer choice who has these numbers.Lets check it out!

A) 11 isn't a multiple of 7

B) 56 isn't a multiple of 7

C) None of these are multiples of 7 except 7 so this is also incorrect

D) This is correct because they are all multiples of 7

Hope this makes sense.

Which lines are perpendicular to the line y –1=1/3(x+2)?

check all that apply

y + 2 = –3(x – 4)

y − 5 = 3(x + 11)

y = -3x – Five-thirds

y = One-thirdx – 2

3x + y = 7

Answers

Perpendicular lines have negative reciprocal slopes (in which the product of those two slopes = -1). The negative reciprocal of 1/3 is -3.

Therefore, the following choices are perpendicular to y — 1 = 1/3(x + 2):


You’ll have to transform option 1 into its slope-intercept form to see whether its slope is a negative reciprocal to 1/3:

OPTION 1:

y + 2 = -3(x - 4)
Distribute -3 into the parenthesis, and subtract 2 from both sides:
y + 2 - 2 = -3x + 12 - 2
y = -3x + 10

OPTION 5:
You’ll also have to transform option 5 into its slope-intercept form:

3x + y = 7
Subtract 3x from both sides to isolate y:
3x - 3x + y = - 3x + 7
y = -3x + 7


OPTION 3:
Option 3 also has a negative reciprocal slope of -3:

y = -3x - 5/3

Therefore, the following options are the correct answers:

Option 1: y + 2 = -3(x —4)
Option 3: y = -3x - Five-thirds or y = -3x - 5/3
Option 5: 3x + y = 7

At the garage sale, each book is priced the same. You purchased 3 fiction books, 5 picture books, 2 non fiction books.and 4 puzzel books. write an expression in simplest form that represents the total amount of money the order will cost

Answers

14x = the total cost of the order


explanation:
since every book is priced the same, you can add them together to get 14. x = the cost of one book, but since we don’t know the cost of one book, we use the variable x. so, 14x is equal to the total cost of the order. hope this helped!

The graph shows the function f(x) = x^2 in blue and another function g(x) in red. which of the following could the equation for g(x)?

Answers

you didn’t post the picture buddy boi

g(x)=1/5x² is the equation for blue graph.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The equation of the red quadratic graph is f(x)=x²

This is the parent quadratic function or the base of the quadratic functions.

This red quadratic graph has been dilated by a certain scale factor  to obtain the blue graph.

Recall that, when the scale factor is a fraction, such that 0<k<1 the graph is stretched horizontally.

The dilated graph then becomes wider than the parent function.

From the given function equations, the possible value of k can only be k=1/5

Therefore the blue graph has equation g(x)=1/5x²

Hence, g(x)=1/5x² is the equation for blue graph.

Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20. The items she bought cost a total of $160 before tax was added. What was the cost of each sweat?

Answers

Answer:

$35

Step-by-step explanation:

first we need to find the amount of money the sweaters cost alone.

so we first subtract the total (160) - the skirt price (20) which is 140

now we divide it by 4 to find the price of each seater, as they all cost the same.

so 140 divided by 4 = 35
