These two lines are parallel Write an equation for each line
The equation of the parallel lines will be y = 0.8x and y = 0.8x - 3.2.
What is the equation of a parallel line?Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.
The intercepts of the line are (0, -3.2) and (4, 0). Then the equation of the line is given as,
y + 3.2 = [(0 + 3.2) / (4 - 0)](x - 0)
y = 0.8x - 3.2
The equation of the other parallel line that passes through the origin will be given as,
y = 0.8x
The equation of the parallel lines will be y = 0.8x and y = 0.8x - 3.2.

B. 25x-2x=-13

Answer:
D
Step-by-step explanation:
Solve the system of linear equations below by substitution.
y = -2x + 6
-4x - 6y = 4
Group of answer choices
(-2, 10)
(5, -4)
(3, 0)
(0, 6)
Answer:
(5, -4)
Step-by-step explanation:
Substitute y from the first equation into the second equation:
-4x - 6(-2x + 6) = 4
Simplify:
-4x + 12x - 36 = 4
8x = 40
x = 5
The only answer choice where x = 5 is (5, -4).
Answer:
[tex]\boxed {\boxed {\sf (5, -4)}}[/tex]
Step-by-step explanation:
We are given the two equations:
[tex]y= -2x+6 \\-4x-6y=4[/tex]
We are asked to solve by substitution. Since we know that y is equal to -2x+6, so we can substitute the expression in for y in the second equation.
[tex]-4x-6y=4[/tex]
[tex]-4x-6(-2x+6)=4[/tex]
Now, solve for x by isolating the variable on one side of the equation.
First, distribute the -6 into the expression. Multiply each term in the parentheses by -6.
[tex]-4x+ (-6*-2x)+(-6*6)=4[/tex]
[tex]-4x+12x+(-6*6)=4[/tex]
[tex]-4x+12x-36=4[/tex]
Combine like terms. There are 2 x terms that can be added.
[tex](-4x+12x)-36=4[/tex]
[tex]8x-36=4[/tex]
36 is being subtracted from 8x. The inverse of subtraction is addition, so add 36 to both sides of the equation.
[tex]8x-36+36=4+36[/tex]
[tex]8x=40[/tex]
x is being multiplied by 8. The inverse of multiplication is division, so divide both sides by 8.
[tex]\frac{8x}{8} =\frac{40}{8}[/tex]
[tex]x=5[/tex]
x is known, so we can find y using the first equation.
[tex]y=-2x+6[/tex]
x is equal to 5, so substitute the value in.
[tex]y=-2(5)+6[/tex]
Multiply first.
[tex]y=-10+6[/tex]
Add.
[tex]y=-4[/tex]

Bright Blocks toy company sells sets of building blocks. The Beginner Builder set has 40 large blocks and 25 small blocks. The Mega Maker set has the same ratio of large blocks to small blocks, but it comes with 100 small blocks.
How many large blocks are in the Mega Maker set? HELPPPPPPPP
The required number of large blocks in the Mega maker set is 160.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
here,
The Beginner Builder set has 40 large blocks and 25 small blocks.
Ratio of large to small blocks = 40 / 25 = 8/5
The Mega Maker set has the same ratio of large blocks to small blocks, but it comes with 100 small blocks.
Let the number of large blocks in the Mega maker set be x,
The ratio of large to small blocks = x / 100
Comparing the ratios,
8 / 5 = x / 100
x = 160
Thus, the required number of large blocks in the Mega maker set is 160.

A salesman's commission is directly proportional to his total sales. If the commission is $100 for $1000 in sales, find the commission for $1750 in sales.
The commission of the salesmen with the given ratio will be $175.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
The commission is $100 for $1000 in sales.
Ratio of commission to sales = 100/1000 = 0.1
With the same ratio,
Commission/1750 = 0.1
Commission = 1750 x 0.1 = $175
Hence "The commission of the salesmen with the given ratio will be $175".

1. A water wheel rung’s height as a function of time can be modeled by the equation:
h - 8 = -9 sin6t
(b) Determine the maximum height above the water for a rung.
Answer:
-1
Step-by-step explanation:
1. A water wheel rung’s height as a function of time can be modeled by the equation:
h - 8 = -9 sin6t
(b) Determine the maximum height above the water for a rung.
Given the rung's height modeled by the equation;
h - 8 = -9 sin6t
h(t) = -9sin6t + 8
At maximum height, the velocity of the rung is zero;
dh/dt = 0
dh/dt = -54cos6t
-54cos6t = 0
cos6t = 0/-54
cos6t = 0
6t = cos^-1(0)
6t = 90
t = 90/6
t= 15
Substitute t = 15 into the expression to get the maximum height;
Recall:
h(t) = -9sin6t + 8
h(15) = -9sin6(15) + 8
h(15) = -9sin90 + 8
h(15) = -9(1)+8
h(15) = -9+8
h(15) = -1
hence the maximum height above the water is -1

Anna has $430. She wants to buy a phone that costs $275. Anna will also have to pay a sales tax of 7%.
How much tax will Anna pay?
What the total price including sales tax?
How much money will Anna have left after her purchase?
Answer:
TOTAL TAX IS: $19.25
TOTAL PRICE IS: $294.25
MONEY LEFT IS: $135.75
Step-by-step explanation:
First, you do a proportion:
?/275 = 7/100
the ?/275 represents how much money in $275
the 7/100 represents 7% (7 hundredths)
then you cross multiply:
275 x 7 = 1925
then you divide:
1925 divided by 100 = 19.25
So $19.25 is the tax amount.
To get the total price, you add:
Tax ($19.25) + Cost($275) = $294.25
$294.25 is the total amount that Anna has to pay.
To get what Anna has left over, you subtract:
Has($430) - Spend($294.25) = $135.75
Anna has $135.75 left.
