Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1

15:X
Cross multiply:15x12
Answer:180
The answer you get divided by 20.
180/20=9.
Answer:
B
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when x = 20, y = 12, then
12 = 20k ( divide both sides by 20 )
k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]
y = [tex]\frac{3}{5}[/tex] x ← equation of variation
When x = 15, then
y = [tex]\frac{3}{5}[/tex] × 15 = 9

Answer:
A. 40.7%
Step-by-step explanation:
The selling price for a $5 profit will be ...
$12.75 +5.00 = $17.75
From $29.95, this represents a change of ...
(17.75 -29.95)/29.95 × 100%
= -12.20/29.95 × 100% ≈ -40.7346%
The bookstore can offer a maximum discount of about 40.7%.

A store is having a sale on walnuts and chocolate chips. For 4 pounds of walnuts and 8 pounds of chocolate chips, the total cost is $25. For 2 pounds of walnuts and 3 pounds of chocolate chips, the total cost is $10. Find the cost for each pound of walnuts and each pound of chocolate chips.
Answers
Answer:
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
Step-by-step explanation:
Let,
x be the price per pound of walnuts
y be the price per pound of chocolate chips
According to given statement,
4x+8y=25 Eqn 1
2x+3y=10 Eqn 2
Multiplying Eqn 2 by 2
2(2x+3y=10)
4x+6y=20 Eqn 3
Subtracting Eqn 3 from Eqn 1
(4x+8y)-(4x+6y)=25-20
4x+8y-4x-6y=5
2y=5
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{5}{2}\\y=2.50[/tex]
Putting y=2.50 in Eqn 2
2x+3(2.50)=10
2x+7.50=10
2x=10-7.50
2x=2.50
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2.50}{2}\\x=1.25[/tex]
Hence,
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

find a number that is exactly halfway between 1 and 27
Answers
Answer:
14
Step-by-step explanation:
A number that is exactly halfway between 1 and 27 is the middle number
In other words, we want to find the median between 1 and 27
Median = (x + y) / 2
Let
x = 1
y = 27
Median = (x + y) / 2
= (1 + 27) / 2
= 28/2
= 14
Therefore, the number between 1 and 27 is 14

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
1. Change the equation to slope intercept form. Identify the slope and y- intercept of the equation. Be sure to show all your work.
2x + 3y= 1470
2x + 3y -2 = 1470 subtract 2x from both sides
3y= 1470 -2x simplify
3y/3= 1470/3 -2x/3 divide both sides by 3
y= -2/3x +490 simplify
-⅔ is the slope and 490 is the y- intercept
2. Describe how you would graph this line using the slope- intercept method. Be sure to write in full sentences.
Start at 490 on the y axis. After that you would use rise over run, down 2 units and right three. Do this until you reach the end of the graph, then go oppisite; up 2 left 3
3. Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.
I CANNOT figure out how to make the equation into notation form. Can someone please help?
