Answer:
y = -¹/₂ x - 6Step-by-step explanation:
Two lines are perpendicular if the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 2x + 3 ⇒ m₁=2
2×m₂ = -1 ⇒ m₂ = -¹/₂
The y-intercept is b=-6 so the equation in slope-intercept form:
y = -¹/₂ x - 6
Find the values of x and y in the equation below.

What is the slope of the line that passes through the points (-9,8) and
(-21, 10)? Write your answer in simplest form.
Answer:
The slope is -1/6
Step-by-step explanation:
We simply use the slope formula here
Mathematically, we have this as;
m = (y2-y1)/(x2-x1)
thus;
m = (10-8)/(-21 + 9) = 2/-12 = -1/6

Factor completely 5x2 − 5x − 100.
Answer:
5(x - 5)(x + 4)
Step-by-step explanation:
Given
5x² - 5x - 100 ← factor out 5 from each term
= 5(x² - x - 20) ← factor the quadratic
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)
The factors are - 5 and + 4, since
- 5 × 4 = - 20 and - 5 + 4 = - 1, then
x² - x - 20 = (x - 5)(x + 4) and
5x² - 5x - 100 = 5(x - 5)(x + 4)

Thomas got a flat tire and had to walk 1/4 mile to the nearest gas station. How many feet did Thomas walk?
Answer:
[tex]1320\ \text{feet}[/tex]
Step-by-step explanation:
The distance Thomas walked to the nearest gas station is [tex]\dfrac{1}{4}\ \text{mile}[/tex].
The conversion factor for miles to feet is
[tex]1\ \text{mile}=5280\ \text{feet}[/tex]
So
[tex]\dfrac{1}{4}\ \text{mile}=\dfrac{1}{4}\times 5280[/tex]
[tex]=1320\ \text{feet}[/tex]
Hence, Thomas had to walk [tex]1320\ \text{feet}[/tex] to get to the nearest gas station.

A. y = 4x
B. 4x - y = -2
C. y = -4x + 6
D. 8x - 2y = 3
E. y = 4x + 9
•
(I think it’s either C, or D, please help I don’t understand)
Answer:
The answer is
[tex]y = - 4x + 6[/tex]
Step-by-step explanation:
Negative reciprocal for the slope.
The equation of the perpendicular line will be y = -4x + d. Then the correct option is C.
What is the equation of a perpendicular line?Let the equation of the line be y = mx + c. Then the equation of the perpendicular line that is perpendicular to the line y = mx + c is given as y = -(1/m) + d. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.
The equation of the line is given as,
y = (1/4)x - 3
The slope of the line is 1/4. Then the slope of the perpendicular line will be - 4. Then the equation of the line is given as,
y = -4x + d
The equation of the perpendicular line will be y = -4x + d. Then the correct option is C.

A shoe store uses a 38% markup to price their items. The store buys the
shoes from the wholesaler for $52. By how much will they mark up the price?
Answer:
They will Markup the price by $19.76.
Step-by-step explanation:
Markup percent = 38%
Wholesale Price = $52
Markup price can be calculated by simply multiplying the wholesale price by 38% or 0.38.
so
Markup price = 38% of 52
= 38/100 × 52
= 0.38 × 52
= $19.76
Therefore, they will Markup the price by $19.76.

Convert factored form to standard form
Answer:
[tex]y - 7x = 21[/tex]
Step-by-step explanation:
Given
[tex]y = (x + 4)7 - 7[/tex]
Required
Convert to standard form
[tex]y = (x + 4)7 - 7[/tex]
Start by opening the bracket
[tex]y = x*7 + 4*7 - 7[/tex]
[tex]y = 7x + 4*7 - 7[/tex]
[tex]y = 7x + 28 - 7[/tex]
[tex]y = 7x + 21[/tex]
Subtract 7x from both sides
[tex]y - 7x = 7x - 7x + 21[/tex]
[tex]y - 7x = 21[/tex]
Hence:
The standard form is: [tex]y - 7x = 21[/tex]

Ms. Gregg spent $14 buying fruit
• Apples cost $2 per pound
• Bananas cost $1 per pound.
• What are some possible amounts of pounds of apples and
bananas that Ms. Gregg could have bought?
Answer:
Ms. Gregg could buy 4 apples and 6 bananas
Step-by-step explanation:
You can split the money and try to get even on each fruit by, getting 4 apples which would be 8 dollars on 4 apples then the extra money would be left over for the bananas which would be six dollars and since the bananas are only 1 dollar you can buy 6 with the leftover money.

How can you use the coordinates of two points on a line to determine the slope of the line?
Answer:
you can use the slope intercept formula!
y2-y1/x2-x1
Step-by-step explanation:
lets take an example!
the coordinates of 1 point are (2,4) and the other point is (4,6)
so lets plug in (x1,y1) (y1,y2)y2 is the y intercept of second point so it is 6 minus y1 which is 4.
6-4/x2-x1
lets do same for x!
6-4/4-2
lets solve
2/2
=1
the slope is 1
You can rent a car via two options. Option A charges $20 per day plus $0.10 per mile. Option B charges $0 per day, but $0.50 per mile. How many miles must you drive in one day for option A to be cheaper?
Answer:
50 miles
Step-by-step explanation:
Step one
given data
let the total charge be y and the number of miles be x
Option A charges $20 per day
plus $0.10 per mile.
y= 20+0.1x---------------1
Option B charges $0 per day,
but $0.50 per mile
y= 0.5x---------------2
equate 1 and 2 we have
20+0.1x=0.5x
20=0.5x-0.1x
20=0.4x
divide both sides by 0.4
x= 20/0.4
x=50 miles
Find AB
D
A
5x B 4x + 3 C
AB
Answer:
15 units
Step-by-step explanation:
ΔADC is an isosceles triangle because it has 2 equal sides
AB = BC (DB is median so cuts AC into 2 equal parts)
AB = 5x, BC = 4x + 3
5x = 4x + 3
5x - 4x = 4x - 4x + 3 (subtracting 4 from both sides)
x = 3
AB = 5x
= 5(3)
= 15 units
