Answer:
[tex]4 - 2y = -2x [/tex]
subtract the 4 from one side
[tex] - 2y = - 2x - 4[/tex]
divide the -2 from the y and the-2x and 4
[tex]y = - x + 2[/tex]
-y + 6 = x
subtract the 6 and add -6 after the x
[tex] - y = x - 6[/tex]
6x - y - 3 = 0
add the y so it cancels out
y = 6x - 3
3y + 15x = -15
subtract the 15x
3y = -15x - 15
divide the 3
y = -5x -5

Natasha is making curtains. Each set of curtains uses 8 yards of fabric. She has 61 yards of fabric. How much fabric will be left over after she makes as many sets of curtains as she can?
Answer: 5 yards will be left over.
Step-by-step explanation:
8 * 7 = 56
so then you would minus 56 from 61 which equals 5. Sorry if that's a weird way to get it but...

As shown on the diagram below ABC ~ DEF, AB=7x, BC=4, DE=7 and EF=x what is the length of AB?
==========================================================
Explanation:
We're told that [tex]\triangle ABC \sim \triangle DE F[/tex] which means triangle ABC is similar to triangle DEF. The order of the letters is important as you'll see in the next two paragraphs.
AB and DE are the first two letters of ABC and DEF respectively. These two sides pair up as one corresponding pair. This forms the fraction AB/DE.
Through similar logic, we get the fraction BC/EF. We have BC and EF as the last two letters of ABC and DEF respectively. This fraction is equal to the previous fraction we set up (due to similar triangles having equal proportions).
Once again, the order of the letters matters to tell us how the sides and angles pair up together.
-----------------
In short, the key takeaway from that last section is that we can form this equation:
AB/DE = BC/EF
From here, we apply substitution and solve for x
So,
AB/DE = BC/EF
7x/7 = 4/x
7x*x = 7*4 .... cross multiplication
7x^2 = 28
x^2 = 28/7
x^2 = 4
x = sqrt(4)
x = 2
We only consider the positive square root because x is some side length. Negative x values are not allowed.
To wrap things up, use that x value to find AB
AB = 7x = 7*2 = 14

Your answer is :
A rotation Turns a shape. Shapes may be rotated clockwise or Counter-clockwise. Whenever we do a rotation, the figure must stay the same size and the same Shape. It is only turned. Figures always rotate around a Point that does not move. If a figure is rotated all the way around back to where it started, this is called a Full Rotation. Half-way around is 180°.

Answer:
43°
Step-by-step explanation:
Equation:m∠ABD = m∠1 + m∠2
Substitute:
68° = m∠1 + (m∠1 + 18°)
Solve:68° = m∠1 + (m∠1 + 18°)
68° = 2(m∠1) + 18°
50° = 2(m∠1)
25 = m∠1
Solution:Know that we know that m∠1 is, we can add 18* to find m∠2
25° + 18° = 43°

HELP PLSSS THIS IS HARD SOMEONEEE
Answer:
Chase is correct. the first one
Step-by-step explanation:
You can substitute a number for a variable and then find the value of the expression. This is called _________________ the expression.
A variable is a letter, for example x, y or z, that represents an unspecified number.
6+x=12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.Step-by-step explanation:

In a regular deck of cards, there are 52 total cards, 26 red, 26 black, and 13 of each of the four suits (hearts, clubs, spades, and diamonds). What is the probability, if you draw a card randomly, that the card will be a heart?
Answer:
13/52 (25%)
Step-by-step explanation:
There are 13 hearts in the deck, and 52 cards in the deck. This means that the probability is 13/52.
What’s does 120$ plus 40% mean
Answer:
ur suppose to find how much it is after the discount so for example in question 1 the discount is 40% so subtract that from 100% to get 60% then multiply this 60% by the origanial vaule which is 120 so for the answer for question 1 would be 72. Also when multiplying 60% u dont multiply by 60 u multiply it by 0.6

A box of cereal states that there are 87 calories in a 3/4 cup serving. What is the unit rate for calories per cup? How many calories are in 2 cups of cereal?
Answer: for 2 cups, There are 232 Calories.
Step-by-step explanation:
Step 1
Let the calories in one cup be represented as C
Therefore
3/4 x C = 87 calories
C = 87 X 4 / 3 = 116
unit rate is 116 calories per cup.
Step 2- Solving the number of calories in 2 cups
1 cup serving = 116 calories
2 cups servings = 116 x 2= 232 calories

Josiah skateboards from his house to school 3 miles away. It takes him 36 minutes.
How many minutes will it take Josiah to skateboard to his friend Sebastian’s house, which is 2 1/2
miles from school, if he travels at the same rate that he did from his house to school?
In the box below, type the number that goes in the blank.
Using the speed - distance relationship, the number of minutes it will take Josiah to cover a distance of 2.5 miles is 30 minutes.
Calculating Josiah's speed :
Speed = (distance ÷ time)Speed = (3 ÷ 36) = 0.08333 miles per minute.
Time taken to cover a distance of 2.5 miles :
Time taken = (Distance ÷ Speed)Time taken = (2.5 ÷ 0.08333) = 30 minutes
Therefore, it will take 30 minutes for Josiah to cover a distance of 2.5 Miles

write linear equatuon relating x and y for each table x (2,4,6,8). y (5,8,11,14)
Step-by-step explanation:
x increases continuously in steps of 2, y increases continuously in steps of 3.
so the slope of the line is y difference / x difference = 3/2. and the slope is siesta the factor of x in the equation
the line equating looks so far like
y = (3/2)×x + b
to get b we use one of the x and y pairs like (2, 5) and put these values in :
5 = (3/2)×2 + b = 3 + b
b = 2
so, the full equation is
y = (3/2)×x + 2
why are 4^0 and (-4)^0 is equal to 1,while -4^0 is equal to -1
Step-by-step explanation:
According to the zero property of exponents, any number (other than 0) raised to the power of zero is always equal to 1.
The problem with this question is the simple fact that in this format it is confusing.
So, -(4^0) = -1 × (4^0) = -1x1 = -1
and, (-4)^0 =1
