What is an equation of the line that passes through the point (−2,−2) and is parallel to the line 5x−y=4?
Answer:
It is -5
Step-by-step explanation:
Answer: y=5x+8
Step-by-step explanation:
first you solve for y:
5x - y = 4
-5x -5x
↓
[tex]\frac{-y}{-1}[/tex] = [tex]\frac{-5x+4}{-1}[/tex]
↓
y = 5x - 4
slope of given line: 5
slope of a parallel line: 5
plug in slope:
y = 5x + b
find b, which is 8 :)
plug it in!
y = 5x + 8

8 cubed in standard form and exponential form
Answer:
so 8 cubed (8 × 8 × 8) in standard form is: 512so 8 cubed (8 × 8 × 8) in exponential form is: 8³Step-by-step explanation:
As we know that
The cube of any given number is that number times itself.
For example, 8 cubed, denoted by 8³ is equal to 8 × 8 × 8.
An exponent basically indicates the number of times we must multiply the base number. For example, to compute 8³, we multiply 3 three times (8×8×8).
so 8 cubed (8 × 8 × 8) in standard form is: 512so 8 cubed (8 × 8 × 8) in exponential form is: 8³Rewrite

6.432 X 105
6.432 X 106
64.32 x 105
64.32 X 106

the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.
Which are the values equivalent to the given expression?Here we start with the expression:
(9.6*10³)*(6.7*10)
Where both numbers are in scientific notation, notice that we can write that product as:
(9.6*10³)*(6.7*10) = (9.6*6.7)*(10³*10) = 64.32*10⁴
Now, remember that in scientific notation, we only can have a single digit in the left of the decimal point, so we can rewrite:
64.32*10⁴ = 6.432*10⁵
So the equivalent expressions are:
(9.6*6.7)*(10³*10) 64.32*10⁴ 6.432*10⁵And the expression in scientific notation is the last one in the bullet points.

Trevor deposited $8,000 into a savings account that earns 4% compound interest. How much interest did he earn after three years?
Answer:
$8998.91
Step-by-step explanation:
8000*1.04^3
it is to the power of 3 because this is the number of years
it is multiplied by 1.04 because there is 4% interest and it is 1.something because you want to add tp the 8000 so you have to multiply it by more than 1
it is 04 because this is where the units go (if it was 40% then the multiplier would be 1.4

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
For 3/4 cup flour = 1/2 cup of milk needed.
So, if the recipe is doubled then flour needed
= 3/4 x 2
= 3/2 cups

Step-by-step explanation:
Arthur sits in the park reading a newspaper, then starts walking home at a constant pace. He stops for bagels, then walks the rest of the way home.
Use the graph to answer questions about this scenario.
1. What does the x-axis represent in this situation?
Write your answer in the space below.
2. What does the y-axis represent?
Write your answer in the space below.
3. During which parts of the graph does Arthur's distance from home decrease?
Write your answer in the space below.
4. When is Arthur waiting for bagels? Explain how you know.
Write your answer in the space below.
5. If Arthur's pace had not been constant after leaving the bagel shop, which part of the graph would change? Explain how that part of the graph would change.
Write your answer in the space below.
6. If Arthur had spent less time reading his newspaper, which part of the graph would change? How would that part change?
Write your answer in the space below.
Answer:
1. The x-axis represents the time duration Arthur spends on the different activities
2. The y-axis represents Arthur's distance from a reference location (home)
3. During parts 2 and 4 Arthur's distance from home decreases
4. Arthur is waiting for bagels in part 3
5. i) The part of the graph that would change if Arthur's pace had not been constant after leaving the bagel shop is part 4
ii) Where by the Arthur's pace is not constant in part 4, there would be more than one different slopes along part 4 and part 4 will not be straight
6) i) If Arthur had spent less time reading his newspaper, the part that would change is part 1
ii) The horizontal length of each part is related directly to the duration of time spent in that part
For a reduction of time in part 1, the length of part 1 will be reduced proportionately to allow for the reduction of time spent in the part
Step-by-step explanation:
Answer:
1. What does the x-axis represent in this situation?
The x-axis represents time.
2. What does the y-axis represent?
The y-axis represents distance.
3. During which parts of the graph does Arthur's distance from home decrease?
Sections 2 and 4.
4. When is Arthur waiting for bagels? Explain how you know.
Section 3. The flat areas represent times when Arthur is not moving. We know that the first flat area shows Arthur reading his newspaper, and the third is when he reaches home; so the second flat area represents the time in which Arthur is waiting for bagels.
5. If Arthur's pace had not been constant after leaving the bagel shop, which part of the graph
would change? Explain how that part of the graph would change.
The part of the graph that would change is part 4. If his pace was not constant, section 4 would not be uniform, and would have many abnormalities. Essentially, Arthur would be randomly speeding up and slowing down.
6. If Arthur had spent less time reading his newspaper, which part of the graph would change? How would that part change?
If Arthur had spent less time reading his newspaper, the whole graph would change. Section one would be shorter, and the entire line would also be shorter. The distance on the graph from the beginning of section 1 to the end of section 5 would be reduced.

Several paint mixtures are made by mixing blue paint and white paint. Paint Colors Blue Paint White Paint Mixture A 5 cups 12 cups Mixture B 6 cups 6 cups Mixture C 4 cups 12 cups Mixture D 5 cups 6 cups Which mixture has the lowest ratio of blue paint to white paint? mixture A mixture B mixture C mixture D
Answer:
The mixture C is the correct option
Step-by-step explanation:
According to the given scenario, the calculation is as follows:
For Mixture A
Blue Paint - 5 cups
White Paint - 12 cups
The ratio between them is 5:12
For Mixture B
Blue Paint - 6 cups
White Paint - 6 cups
The ratio between them is 6:6 = 12:12
It came by multiply the numerator and denominator by 12
For Mixture C
Blue Paint - 4 cups
White Paint - 12 cups
The ratio between them is 4:12
For Mixture D
Blue Paint - 5 cups
White Paint - 6 cups
The ratio between them is 5:6 = 10:12
It came by multiply the numerator and denominator by 12
As it can be seen that in all four mixtures the denominator is the same so for calculating the lowest ratio we have to see the small value in the numerator
As it can be seen that there is a small value of 4
hence, the mixture C is the correct option
Answer:
C mixture
