Answer:
1st: 4
2nd: -16
Step-by-step explanation:
Trust the process
The required equation of the parallel line is 4x + y = 16.
Given that,
On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5), what is the equation of the line parallel to the given line with an x-intercept of 4 is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The slope of the parallel line,
m = 5 + 3 / -3 + 1
m = 8 / -2
m = -4
Now,
The line has the x-intercept at x = 4,
so the ordered pair will be (4,0)
Point-slope of the equation of the line is given by,
y - y₁ = m(x - x₁)
y - 0 = -4 (x - 4)
y = -4x + 16
4x + y = 16
Thus, the required equation of the parallel line is 4x + y = 16.

Answer:
x = 2, y = 4
Step-by-step explanation:
We can solve the system of equations using substitution. (We can't use elimination for a problem like this because there's no addition or subtraction in the first equation, and besides, it would make it longer.)
Replace the y value in [x = -y + 6] with "2x", because y = 2x.
x = -2x + 6
From there, we can solve the linear equation.
x = -2x + 6
add 2x to both sides
3x = 6
divide by 3
x = 2
From x, we can also figure out what y equals.
Replace the x value in [y = 2x] with "2", because x = 2.
y = 2*2
y = 4
x = 2 and y = 4

Answer:
20cm^3
Step-by-step explanation:
The figure is composed by two parallelepipeds
first one
base area = 2 x 1 = 2 cm^2
height = 3 + 2 = 5 cm
V = base area x height
V = 2 x 5 = 10cm^3
second one
base area = 2 x 1 = 2 cm^2
height = 7-2 = 5 cm
V = 2 x 5 = 10 cm^3
total volume = 10 x 2 = 20 cm^3

18.Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix and y bottles of water. They bought a total of 11 items. The system of equations can be used to determine how many of each item they bought.
Answer:
bags of snack = x = 6
bottles of water = y = 5
Step-by-step explanation:
The system of equations can be used to determine how many of each item they bought.
20.00=2.50x+1.00y
11=x+y
how many bags of snack mix did they buy?
Let
bags of snack = x
bottles of water = y
20.00 = 2.50x + 1.00y (1)
11 = x + y (2)
From (2)
x = 11 - y
Substitute x = 11 - y into (1)
20.00 = 2.50x + 1.00y
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = -2.50y + 1.00y
-7.5 = -1.5y
y = -7.5/-1.5
y = 5
Substitute y = 5 into (2)
11 = x + y
11 = x + 5
11 - 5 = x
x = 6
bags of snack = x = 6
bottles of water = y = 5

I have the answer I just have this one question. Will all the paint fit into the bucket?
There are 4 pints of green paint in a gallon bucket. The paint is made from equal amounts of yellow paint and blue paint. To create a different shade of green, the mixture needs to be 80% yellow. How many pints of yellow paint need to be added to the bucket to make the mixture 80% yellow?
Brandon says to get that shade of green, 6 pints of yellow paint need to be added to the bucket. Bianca says that won't work. In two or more complete sentences, explain who is correct and why. In your explanation, include the calculations to support the correct answer.
Answer:
brandon
Step-by-step explanation:
Initially, there id 4 pints of green paint in the bucket.
As the green paint is made from equal amounts of yellow paint and blue paint, so, the initial amount of yellow and blue paint in the bucket is 2 pint each.
Let x pints of yellow paint to be added to the bucket to make the desired shade.
Total amount of the paint in the bucket, after addition of pints of yellow color become pint, in which the ampunt of yellow color is pints.
As, the ampunt of yellow color is 80% of the total amount of the mixture, so
So, 6 pints of yellow paint to be added to the bucket to make the desired shade.
Hence, Brandon is correct.

2, 7, 12
2, 10, 50
5, 7, 9
5, 10, 20
Answer:
2nd option
Step-by-step explanation:
Using [tex]a_{n}[/tex] = 5[tex]a_{n-1}[/tex] and a₁ = 2 then
a₂ = 5 × a₁ = 5 × 2 = 10
a₃ = 5 × a₂ = 5 × 10 = 50
the first 3 terms are 2, 10, 50
The first three terms of the given sequence are 2, 10, 50
What is sequence?A sequence in which every term is obtained by multiplying or dividing a definite number with the preceding number is known as a geometric sequence.
Given that, a sequence can be generated by using aₙ₋₁ = 5 and a₁ = 2,
We need to find the first three terms of the sequence,
Therefore, aₙ₋₁ = 5 and a₁ = 2 then
a₂ = 5 × a₁ = 5 × 2 = 10
a₃ = 5 × a₂ = 5 × 10 = 50
Therefore,
The first 3 terms are 2, 10, 50
Hence, the first three terms of the given sequence are 2, 10, 50

Natalie is a salon owner. Yesterday, she did 3 haircuts and colored the hair of 1 client,
charging a total of $239. Today, she did 2 haircuts and colored the hair of 1 client, charging a
total of $192. How much does Natalie charge for her services?
Natalie charges $___
for a haircut and $__
for a coloring
Answer:
1 haircut = 47 dollars
1 colouring = 98 dollars
Step-by-step explanation:
Let [tex]x[/tex] be equal to the cost of 1 haircut.
Let [tex]y[/tex] be equal to the cost of 1 colouring treatment.
1) Form equations
Equation 1: 3 haircuts + 1 colour = 239 dollars
⇒ [tex]3x+y=239[/tex]
Equation 2: 2 haircuts + 1 colour = 192 dollars
⇒ [tex]2x+y=192[/tex]
2) Solve the system of equations
Subtract equation 2 from equation 1 to cancel out y (elimination)
- [tex]3x+y=239\\2x+y=192[/tex]
⇒ [tex]3x-2x+y-y=239-192\\x=47[/tex]
Therefore, Natalie charges 47 dollars for 1 haircut.
Plug x back into one of the equations to solve for y
[tex]2(47)+y=192\\94+y=192[/tex]
Subtract both sides by 94
[tex]94+y-94=192-94\\y=98[/tex]
Therefore, Natalie charges 98 dollars for 1 colouring treatment.

Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
What is the solution to the equation = 25?
x = 5
x = 10
x = 25
x = 125
Answer:
x=125
Step-by-step explanation:
To solve we must find a number that when divided by 5 equals 25.
To do this we can either...
Take each answer choice and plug in the value into the x spot and see if it works...
5/5=25 WRONG
10/5=25 WRONG
25/5=25 WRONG
125/5=25 CORRECT!
ORRR... we can set the equation so that the x is alone on one side.
To do this we can multiply both sides by 5
[tex]\frac{x}{5}[/tex]=25 ---> x=25×5
x=125

(( Ignore the first answer, I didnt mean to put true-)
Answer:
1) False
2) True
3) True
4) False
Step-by-step explanation:
For the first statement, we can look at a graph with the line of y = 3.69x plotted. If we check the points (7.38, 2) and (11.07,3), they do not intersect with the line. So, the first statement is false.
For the second statement, we can check the equation for the line to find the slope. The equation, y = 3.69x, is in slope-intercept form, or [tex]y = mx + b[/tex]. In this form, [tex]m[/tex] is the slope of the line. [tex]b[/tex] is the y-intercept. In this line, there is no y-intercept specified, so we can take this to mean the y-intercept is 0. The slope, we can see, is 3.69. The slope, multiplied by x, shows us any point of the line. The second statement, then, is true.
The next statement can be verified by finding just how much 16 gallons will cost. Like we've seen before, the slope can be multiplied by x, the number of gallons, to see where that point will be plotted. So, we can multiply the slope by 16.
3.69 · 16 = 59.04
The (x) value, we already know, is 16. The (y) value, we've found, is 59.04. So 16 gallons will be plotted at (16, 59.04). The third statement is true.
The last statement says that if the price increases by $0.05, the slope will be 3.64. We can tell this is false by adding 0.05 to the original slope, 3.69.
3.69 + 0.05 = 3.74
3.74 ≠ 3.64, so the last statement is false.
I hope this was helpful to you ^^
