Answer: y=−4/5x−4
Step-by-step explanation:
5y+4x=−20
Step 1: Add -4x to both sides. 4x+5y+−4x=−20+−4x 5y=−4x−20
Step 2: Divide both sides by 5.
y=−4/5x−4

Consider the following pair of equations:
y = −2x + 8
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
y+2x=8.....(1)
y-x=-1.......(2)
in equation (2) make x the subject of the formula x=y+1
substitute y+1 for x in equation (1)
y+2(y+1)=8
y+2y+2=8
3y=8-2
y=2
substitute 2 for y in equation 2
y-x=-1
2-x=-1
x=2+1
x=3
y=2 x=3
So I need help with 1 over x minus 8 so like 1/x-8 this is a negative exponent
Answer and Step-by-step explanation:
one divided by (in parentheses) x minus eight should look like this:
[tex]\frac{1}{x-8}[/tex]
This is a graph of this expression.

Ralph has $10 in his wallet he wants to buy 5 pencils, 3 pens, 2 notebooks from the school store how much more money dose he need
Answer:
The correct answer is 1.75
Step-by-step explanation:
5 x 0.50 = 2.5
3 x 1.25 = 3.75
2 x 2.75 = 5.5
Then we want to add
2.5 + 3.75 + 5.5 = 11.75
Now, Subtract.
11.75 - 10.00 = 1.75
The total amount spent will be equal to $12, so the money added by Ralph will be equal to $2.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data given in the question,
The total money Ralph has is $10.
Price of each pencil = $0.50
Then, price of 5 pencil will be = 5 × 0.50 = $2.5
Price of each pen = $1.25
Then, the price of 3 pens will be = 3 × 1.25 = 3.75
Price of each notebook = $2.75
Then, the price of 2 notebooks will be = 2 × 2.75 = 5.5
Then, the total money spent by Ralph = 5.5 + 3.75 + 2.75 = 12
The money that he should have to add will be,
$12 - $10 = $2

Cindy has -$40 in her bank account. She earns $100 babysitting so she deposited it into her account. She then withdrew $50. How much does her bank account have now?
Answer:
$10
Step-by-step explanation:
Let's take this step by step. First, we know that Cindy has -$40 in her bank account. She then adds the $100 she earned, so we add -40 and 100:
-40 + 100 is the same as 100 - 40, which is 60. So, Cindy now has $60 in her bank account. Next, she took out $50. We must subtract that from what she has from her bank account:
60 - 50 = 10
Therefore, Cindy has $10 in her bank account now.

Find the slope of (-8.-4) and (-4,-9
Answer: -5/4
Step-by-step explanation:
Answer:
= -5/4
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -9 - -4)/( -4 - -8)
= ( -9 +4)/( -4 +8)
= -5/4
Which of the following is a solution to the inequality below?
4 - V > 12
V-8
V="12
V-6
Submit
Answer:
V>-8
Step-by-step explanation:
The given inequality is :
4-V>12
Subtracting 4 from both sides.
4-V-4 > 12-4
-V>8
or
V>-8
So, the value of V is more than -8.

A
15 feet below the surface
B
18 feet below the surface
33 feet below the surface
D
48 feet below the surface
(0) А.
OB
OC
OD
Answer: 48 feet below the surface
Step-by-step explanation:
From the question, we are informed that two divers are underwater. Nick is 33 feet below the surface while Tristan is 15 feet above him.
Tristan's depth will be represented as x.
Therefore, x - 33 = 15
x = 15 + 33
x = 48
Therefore, the answer is 48 feet below the surface.
Answer:
B 18 feet below
Step-by-step explanation:
So subtract 33-15 bechas depth means below and since tristan has less of a depth to go rather than Nick you would subtrac.

What is the volume of this rectangular prism?
Answer:
1cm³
Step-by-step explanation:
You do not need a calculator for this.
The formula for the volume of a rectangular prism is:
Length × Width × Height = Volume
If we substitute our numbers in:
5/4 × 4/3 × 3/5 = 1cm³
All you need to do is multiply across.
5 × 4 × 3 = 60
4 × 3 × 5 = 60
The numerator and denominator both equal 60. So the fraction would look like this if you were to keep it as a fraction.
60/60
The grade of a hill is its steepness represented as a percent. Jin tracks his walking speed up different hills. What does the rate of change, or slope,
represent in this situation?
Answer: The rate represents a decrease in speed for each 1% grade increases.
Step-by-step explanation:
You can use the fact that normal slope is measurement of how much the height changes as we walk on the ground for a unit distance forward. And that percent calculates everything compared to 100 parts.
The rate of change or slope, in this situation tells that if we walk 100 units horizontally, then the slope percent gives us the amount of height increased compared to height before walking 100 units.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
How to measure the rate of change of something as some other value changes?Suppose that we have to measure the rate of change of y as x changes, then we have:
[tex]Rate = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where we have
[tex]\rm when \: x=x_1, y = y_1\\when\: x = x_2, y= y_2[/tex]
Remember that, we divide by the change in independent variable so that we get some idea of how much the dependent quantity changes as we change the independent quantity by 1 unit.
(5 change per 3 unit can be rewritten as 5/3 change per 1 unit)
Converting rate of change or slope to percentage(where dependent variable is height and the independent variable is the distance walked horizontally)
Slope percent = [tex]Slope \times 100[/tex] = [tex]\dfrac{y_2 - y_1}{x_2 - x_1} \times 100[/tex]
This, shows that, if we walk 100 units horizontally, then the slope percent gives us the amount of height increased.

Answer:
Increasing
Step-by-step explanation:
Let us take a look, at these fractions in decimal forms.
1/7 = 0.14
2/7 = 0.28
3/7 = 0.42

factorise x^12 y^4 - x^4 y^12
PLEASE PLEASE explain in step by step Pleasseeeeee
Answer:
Step-by-step explanation:
First, look at your terms. You have two terms and two variables in each. So they can be factored out because you can distribute them back in easily.
Focus one variable first, x. You cant factor an x^12 out of an x^4. You can, but you really don't want to, it'll turn your problem into a mess. So the only thing you can do is factor out the lower exponent, x^4.
[tex]x^4(x^8y^4-y^1^2)[/tex]
We arent done yet because the terms still share the y variable. You cant factor a y^12 from a y^4. This is the same problem with the x variable. So take out the lower one, y^4.
[tex]x^4y^4(x^8-y^8)[/tex]
