Answer:
Call the line (d): y = ax + b
(d) intersects the vertical axis at the point where the intersection is 3 ⇒x = 0, y = 3 Instead of (d) we have: b = 3
(d) intersects the horizontal axis at the point where the coordinate is -1 ⇒x = −1, y = 0 Instead of (d) we have: −a + b = 0
Replace into b = 3 into -a + b = 0 we have: −a + 3 = 0⇔a = 3
So the equation for the line is y = 3x + 3

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]
[tex] - 10 = 2x + 6[/tex]

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.

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.
Please help explain how to do this
Answer:
Any number that isn't 3.
Step-by-step explanation:
Any other number should work, so I'll just show you what happens if you use 3.
2(3x - 2) = 6x + 5
6x - 4 = 6x + 5
-4 ≠ 5
As you are aware, that would make it no solution hence why it can't be used.

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

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
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

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
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 zoo keeper wants to fence a rectangular habitat for goats. The length of the habitat should be at least 80 feet and the perimeter of the habitat should be no more than 300 feet
Write a system of linear inequality:___________
Please help!! It’s due within 20 minutes!! Please..
Answer:
Step-by-step explanation:
Let x ft be the length of the fence and y ft be the width of the fence.
1. The length of the habitat should be at least 80 feet, then
2. The perimeter of the habitat should be no more than 300 feet. The perimeter of the fences 2x+2y ft, then
3. The system of inequalities that represent the model is
The graph of these inequalities is attached.
Two possible solutions are
1. x=100 ft, y=20 ft (100≥80 and 2·100+2·20=240≤300);
2. x=110 ft, y=30 ft (110≥80 and 2·110+2·30=280≤300).
