The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
5x - y = 8 ( subtract 5x from both sides )
- y = - 5x + 8 ( multiply through by - 1 )
y = 5x - 8 ← in slope- intercept form
with slope m = 5 and y- intercept c = - 8

find the equation of the line that passes through the point (1,4) and is parallel to y=3x+11
Answers
Answer:
y = 3x + 1
Step-by-step explanation:
Since we know the Graph is Parallel to y = 3x + 11, we know that the "mx" portion of the equation is 3x since only the "b" would be different.
Then we just substitute in the point and to find b.
4 = 3(1) + b
b = 1
y = 3x + 1 is the answer

Answer:
Given Below
Step-by-step explanation:
using the formula :
y = mx + c ....where m is the slope and c is the y intercept
(a) if Slope = -3; y-intercept = 2
y = -3x + 2
(b) if Slope = -1; y intercept = 8
y = -1x + 8
y = -x + 8
(c) if Slope = 1/4; y-intercept= 0
y = x/4 + 0
y = x/4

The perimeter of a rectangular painting is 326 centimeters. If the length of the painting is 88 centimeters, what is its width?
Answers
Answer:
The width is 75 cm
Step-by-step explanation:
Perimeter is L+L+W+W aka 2L+2W
L=length W=width
326=2(88)+2W
Solve for W
326=176+2w
150=2w
w=75
Answer:
Width = 75 cm
Step-by-step explanation:
l = 88 cm
Perimeter = 326 cm
2l +2w = 326
2*88 + 2w = 326
176 + 2w = 326
Subtract 176 from both sides
2w = 326 - 176
2w = 150
Divide both sides by 2
w = 150/2
w = 75

an account is with an initial deposit of $1500 earns 7 percent interest for 1.5 years what is the ending balance enter your answer in the box
Answers
Answer:
$ 1,657.50
Step-by-step explanation:
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation
A = 1500(1 + (0.07 × 1.5)) = 1657.5
A = $ 1,657.50
The total amount accrued, principal plus interest,
from simple interest on a principal of $ 1,500.00
at a rate of 7% per year
for 1.5 years is $ 1,657.50.

The simple interest is $ 157.50 and amount after 1.5 years is $ 1657.50
What is Simple Interest?
Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) 100
Given data ,
Let the deposit amount be Principal P = $ 1500
Let the rate of interest be R = 7 %
Let the number of years be T = 1.5 years
Now , the simple interest is calculated by the formula ,
Simple Interest I = ( Principal x Rate x Time ) / 100
Substituting the values in the equation , we get
Simple Interest I = ( 1500 x 7 x 1.5 ) / 100
Simple Interest I = 15 x 10.5
Simple Interest I = $ 157.50
Therefore , the amount after 1.5 years is given as
Amount A = Principal P + Simple Interest
Amount A = 1500 + 157.50
Amount A = $ 1657.50
Therefore , the value of A is $ 1657.50
Hence , The amount after 1.5 years is $ 1657.50

Stefan sells jin a bicycle for $114 and a helmet for $18. The toltal cost for jin is 110% of what stefan spent originally to buy the bike and helmet. How much did stefan spend originally? How much money did he make by selling the bicycle and helmet to jin?
Answers
Answer:
$ 12
Step-by-step explanation:
First, we'll find out how much, in total Jin spent.
114 (bicycle) + 18 (helmet) = $ 132
Now, we know she spent 110% of what Stefan did.
132 = 110% of x (the value stefan spent)
So, we want to get x, the cost, by itself. We will divide 110.
132/110(%) = x
Remember, percent is a decimal that's been moved (2 places to the right), so... (we move it 2 places to the left for a decimal)
132/1.10 = 120
Stafen originally spent $120 on the equipment. Now we subtract this amount from what Jin spent:
132 - 120 = 12
Stefan made $12 off of Jin's purchase.

Chase is making a cake for his daughter's birthday. The normal recipe
calls for 8 ounces of butter and 16 ounces of sugar. Chase then
decides to make a slightly smaller cake and only use 6 ounces of
butter. How many ourses of sugar will he need in his smaller cake?
Answers
Answer:
12 ounces of sugar
Step-by-step explanation:
According to the original recipe whatever the ounces of butter is, you multiply it by 2 to get the ounces of sugar. Therefore, 6 x 2 = 12. 12 ounces of sugar.
I would say since
6÷8 is 0.25 we are removing 25% of butter
So logically you would remove 25% of the ounces of sugar, so 16*0.25 is 4
so 16-4
12
I'd say 12 ounces of sugar
