Which graph best represents -2y =4x - 8 ? ASAP like RIGHT NEOW
Answers
The equation - 2y = 4x - 8 in slope intercept is y = - 2x + 4.
Consider the function,
- 2y = 4x - 8
The equation of a line in slope intercept form is y = mx + b where m is the slope and b is the y-intercept.
So,
- 2y = 4x - 8
y = - 2x + 4
Now,
When x = 0
y = - 2(0) + 4 = 4
When x = 1,
y = - 2(1) + 4 = 2
When x = 2,
y = - 2(2) + 4 = 0
When x = - 1,
y = - 2( - 1 ) + 4 = 6
When x = - 2,
y = - 2( - 2 ) + 4 = 8
When x = 3,
y = - 2( 3 ) + 4 = - 2
So, the point on the graph are ( 0, 4 ), ( 1, 2 ), ( 2, 0 ), ( 3, - 2), ( - 1, 6 ), ( - 2, 8 ).
Therefore, the graph of the function is:

This shape is made up of one half-circle attached to a square with side lengths 11 inches. You can use 3.14 as an approximation for π. help i don't know it
Answers
The approximate perimeter of the entire shape is 50.27 inches.
How to find the perimeter of a figure?The perimeter of a figure is the sum of the whole sides of the figure.
Therefore, the perimeter of the entire shape can be calculated as follows:
The shape is made of three sides of a square and half a circle.
Therefore,
circumference of the semi circle = πr
r = 11 / 2 = 5.5 inches
circumference of the semi circle = 5.5π
Hence,
perimeter of the shape = 11 + 11 + 11 + 5.5π
perimeter of the shape = 33 + 5.5(3.14)
perimeter of the shape = 33 + 17.27

A side of the triangle below has been extended to form an exterior angle of 156°. Find

Answers
The value of x of angle ∠C is 66°.
What are angles?An angle is a figure formed by two rays or lines that have the same endpoint in plane geometry. The Latin word "angulus," which means "corner," is where the word "angle" originates. The common endpoint of the two rays—known as the vertex—is referred to as an angle's sides. Depending on the measurement, there are various angles in geometry. Basic angles are identified by their names: acute, obtuse, right, straight, reflex, and full rotation.So, the value of x:
As we can see that A is a straight angle. Then ∠BAC will be:
156 + ∠BAC = 180∠BAC = 180 - 156∠BAC = 24°Now, we know that in △ABC, ∠A = 24° and ∠B = 90° (Given), then ∠C will be:
x + ∠A + ∠B = 180x + 24 + 90 = 180x + 114 = 180x = 180 - 114x = 66Therefore, the value of x of angle ∠C is 66°.

how much will Yoona charge to walk 8 dogs
Answers
Yoona will charge $20.75 to walk 8 dogs based on the trend of Yoona charges to walk dogs.
How to find the amount to be charged?First, find the pattern in the amount that Yoona charges to walk each additional dog.
Additional cost to walk 2 dogs:
= 40 - 37.25
= $2.75
Additional cost to walk 3 dogs:
= 37.25 - 34.50
= $2.75
Additional cost to walk 4 dogs:
= 34.50 - 31.75
= $2.75
Every extra dog therefore leads to a fall in price by $2.75. For eight dogs, Yoona would charge:
= 40 - (7 x 2.75)
= 40 - 19.25
= $20.75

A contractor purchases 7 dozen pairs of padded work gloves for $99.96 . She incorrectly calculates the unit price as $14.28
per pair for the expense report. What is the correct unit price? What is the error?
Answers
The cost or unit price for purchasing each pair of work gloves is $1.19.
The cost of 7 dozen pairs of padded work gloves purchased by the contractor is $99.96.
The incorrect unit price calculated by the contractor is $14.28 per pair.
Now, we know 1 dozen is equal to 12 units.
Therefore,
The number of pairs of gloves purchased = 7 × 12 = 84
As the total cost is $99.96, the cost of each pair will be:
= $99.96 ÷ 84
= $1.19
The error by the contractor was that she didn't consider the word dozen in his calculation. She simply divided the total cost by 7 to calculate the price per pair.
The unit price of purchasing each pair of work gloves is $1.19.

Find the perimeter of ALMN. Round your answer to the nearest tenth if necessary.
Answers
Answer:
148
Step-by-step explanation:
The triangle are similar because the angle measurements are the same.
180-51-34 = 95
180-95-51 = 34
If we match up the corresponding sides we see that the side with 45 corresponds to the side with 36. Now we need to find the scale factor.
Let s = the scale factor
45s = 36 Divide both sides by 45
s = .8
This means that the corresponding length of the triangle on the right is .8 of the triangle on the left.
The corresponding side to x is 79, so 79 x .8 = 63.2. Now that we know the three sides we can add them together to find the perimeter.
63.2 + 36 + 48.8 = 148

The correlation coefficient (r) between the number of volunteers x and the number of bags of trash collected y is 0.964.
What percent of the variation in the number of bags of trash collected can be explained by differences in the number of volunteers?
Answers
The correlation coefficient between the number of volunteers x and the number of bags of trash collected y, so the percentage of variation in the number of bags of trash collected is 92.92 %.
What is the Correlation coefficient?You may gauge how closely two variables are related by looking at their correlation coefficients. Pearson's correlation coefficient is the most often used of the several correlation coefficient types. Often employed in linear regression, Pearson's correlation (also known as Pearson's R) is a correlation coefficient. It's likely that you'll learn about Pearson's R first if you're just getting started in statistics. Actually, Pearson's is typically mentioned when someone mentions the correlation coefficient.
According to the question,
The correlation coefficient i.e., r between x and y is 0.964.
r = 0.964
Squaring on both sides :
r² = 0.964²
r² = 0.9292
Now, convert this into percentage form by multiplying it will 100.
⇒0.9292 × 100
= 92.92 %.
Hence, the percentage of the variation will be 92.92 %.

number sentence 1:
number sentence 2:
Answers
At the unit rate of reading 93.5 books in 8.5 months, Annarose expects to read 132 books annually.
What is the unit rate?The unit rate is the ratio or speed that Annarose reads books.
From her established unit reading rate, she reads 11 books in a month.
The unit rate is computed by ensuring that the denominator becomes 1 after the division operation.
The number of books she read in 8.5 months = 93.5 books.
The number of books she can read in 1 month = 11 books (93.5/8.5).
The number of books she can read in 12 months = 132 books (11 x 12).

(round your answers to the nearest cent.)
Answers
The balance in the account at the end of two years is $864.
The interest earned by Suki during that time is $64.
The initial principal amount "P" is $800.
The interest rate "R" is 4%.
The interest is compounded quarterly.
This means the value of "n" is 4.
The time period for which the interest is earned is 2 years.
The formula for compound interest is :
A = P*[1 + (R/n)]^(n*t)
A = 800*[1 + (0.04/4)]^(4*2)
A = 800*[1 + 0.01]^(4*2)
A = 800*[1.01]^(8)
A = 800*1.08
A = 864
The total interest earned is the final amount minus the principal amount.
The total interest earned is $864 - $800.

Answers
The interest earned by Ryan is $131.44 and the interest earned by Brian is $32.86 .
In the question,
it is given that
amount deposited by Ryan = $775
time for which the amount is deposited = 4 years
rate at which the amount is deposited = 4.24%
So the simple interest = (p*r*t)/100
= (775 * 4.24*4 ) /100
= 13144/100
= 131.44
amount deposited by Brian = $775
time for which the amount is deposited = 1 years
rate at which the amount is deposited = 4.24%
So the simple interest = (p*r*t)/100
= (775 * 4.24 * 1 ) /100
= 3286/100
