Write the equation of the line in slope-intercept form that passes through the given points.
(-1, 8) and (5,-2)

Answers

Answer 1

Answer:

y = -5/3x + 19/3

Step-by-step explanation:

y2 - y1 / x2 - x1

-2 - 8 / 5 - (-1)

-10/6

= -5/3

y = -5/3x + b

8 = -5/3(-1) + b

8 = 5/3 + b

19/3

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

answer: $35

Answer:

yes i think u are correct

Step-by-step explanation:

Answer:

some are correct but some are not.

Step-by-step explanation:

You got to pay attention to all the negatives in the equations. Number 3 is incorrect. The reason is  you started the plot at positive 6 not negative 6

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!

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

Recall that [tex]0.\overline{1}=1/9[/tex].

So, we want [tex]42/100+1/9*1/1000[/tex].

This simplifies to [tex]21/50+1/9000[/tex].

We know that [tex]21/50=(21*180)/(50*180)=3780/9000[/tex].

Step-by-step explanation:

Supplementary angles add up to 180 degrees to make a straight line.

The red square in one of them indicates that it is 90 degrees on their side which means that it is 90 degrees on the other where (6x+2) and 40 degrees are.

(6x+2) + 40 = 90

6x + 42 = 90

Recall that the perimeter of a rectangle is P=2(W+L), where W is the width and L is the length. The length of a rectangle is 23 feet more than the width. If the perimeter is 70 feet, then what is the length of the rectangle, in feet?

Answers

Answer:

Length = 6 + 23 = 29 feet

Step-by-step explanation:

Width = x

Length = x + 23

2x + 2(x+23) = 70

2x + 2x + 46 = 70

4x = 70-46

x = 24/4

x = 6

one number is 15 more than a second number.The sum of the number 115. What are the numbers?

Answers

The first number is 65
The second number is 50

X= first number
Y= second number

X+Y= 115 > or 2y+15= 115 > subtract 15 from both side

2y= 100> divide by 2 on each side> y=50

There you have solved for y, now solve x

X= 50+15 > which is 65

So therefore, the first number is 65 and the second is 50.
