By rearranging x = 7y - 5 to make y the subject, we get
x + 5 = 7y ( By transposition method )
or, [tex] \huge \purple {\tt {\frac{x + 5}{7} = y}} [/tex]
Answer:[tex] \huge \pink {\tt {y = \frac{x + 5}{7}}} [/tex]
The equation x = 7y - 5 can be rearranged as y = x/7 + 1/7 after making the subject as y.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The equation is:
x = 7y - 5
To make the subject as y:
x + 5 = 7y
Or
7y = x + 5
y = 1/7[x + 5]
y = x/7 + 1/7
Thus, the equation x = 7y - 5 can be rearranged as y = x/7 + 1/7 after making the subject as y.

Which describes the correlation shown in the scatterplot?
On a graph, points are grouped together and decrease.
A. There is a positive correlation in the data set.
B. There is a negative correlation in the data set.
C. There is no correlation in the data set.
D. More points are needed to determine the correlation.
It can be said that the "there is a negative correlation in the data set". Option B is correct.
The graph shows points that are grouped together and are decreasing.
The gathered data shows that there is a possibility to get correlation between them.
The group of data is decreasing. So, the correlation of the data will be negative in nature.
Therefore, it can be said that the "there is a negative correlation in the data set". Option B is correct.

Statistics and probability: If the glucose level is above 160mg per dl one hour after a sugary drink, Sheila's measured glucose level one hour after the sugary drink varies according to the normal distribution with the mean being 145mg/dl and a standard deviation of 11mg/dl. If a single glucose measurement is made, what is the probability that Sheila is diagnosed with gestational diabetes?
Answer:
0.0863
Step-by-step explanation:
Given that:
The mean =145
The standard deviation = 11
To find P(X ≥ 160) :
Z = (x - μ)/σ
Z = 160 - 145/ 11
Z = 1.364
From the standard normal z table
Thus;
P(X ≥ 160) = 1- P(Z < 1.364)
P(X ≥ 160) = 1 - 0.9137
P(X ≥ 160) = 0.0863

Answer:
y = -1
Step-by-step explanation:
Any ordinate pair (x, y) represents the input output values of a function to be graphed.
For any input value of x, there will be an output value (y).
If input value for the graph attached is x = 0,
Output value will be represented by the y-value along y-axis as, y = -1
Therefore, y = -1 will be the answer.

Answer:
20. AB = 42
21. BC = 28
22. AC = 70
23. BC = 20.4
24. FH = 48
25. DE = 10, EF = 10, DF = 20
Step-by-step explanation:
✍️Given:
AB = 2x + 7
BC = 28
AC = 4x,
20. Assuming B is between A and C, thus:
AB + BC = AC (Segment Addition Postulate)
2x + 7 + 28 = 4x (substitution)
Collect like terms
2x + 35 = 4x
35 = 4x - 2x
35 = 2x
Divide both side by 2
17.5 = x
AB = 2x + 7
Plug in the value of x
AB = 2(17.5) + 7 = 42
21. BC = 28 (given)
22. AC = 4x
Plug in the value of x
AC = 4(17.5) = 70
✍️Given:
AC = 35 and AB = 14.6.
Assuming B is between A and C, thus:
23. AB + BC = AC (Segment Addition Postulate)
14.6 + BC = 35 (Substitution)
Subtract 14.6 from each side
BC = 35 - 14.6
BC = 20.4
24. FH = 7x + 6
FG = 4x
GH = 24
FG + GH = FH (Segment Addition Postulate)
[tex] 4x + 24 = 7x + 6 [/tex] (substitution)
Collect like terms
[tex] 4x - 7x = -24 + 6 [/tex]
[tex] -3x = - 18 [/tex]
Divide both sides by -3
[tex] x = 6 [/tex]
FH = 7x + 6
Plug in the value of x
FH = 7(6) + 6 = 48
25. DE = 5x, EF = 3x + 4
Given that E bisects DF, therefore,
DE = EF
5x = 3x + 4 (substitution)
Subtract 3x from each side
5x - 3x = 4
2x = 4
Divide both sides by 2
x = 2
DE = 5x
Plug in the value of x
DE = 5(2) = 10
EF = 3x + 4
Plug in the value of x
EF = 3(2) + 4 = 10
DF = DE + EF
DE = 10 + 10 (substitution)
DE = 20

Which of the following statements correctly describes the temperature? A. It was -2°F when the temperature was first measured, and it is rising by 43 degrees per hour. B. It was 43°F after four hours, and it is dropping by 2 degrees per hour C. It was -2°F after four hours, and it is rising by 43 degrees per hour D. It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour
Answer:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 8 is an equation.
We have,
y = -2x + 43
Where y is the temperature after x hours.
Now,
At x = 0,
y = 43
This means the temperature is 43 when it first started to measure.
At x = 1,
y = 41
This means,
The temperature decreases by 2 degrees per hour
Thus,
It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.
Option D is the correct answer.

Nathan is opening a savings account that has a 10% simple interest rate. He deposits $75 in the account. After 5 years, he will have $112.50 in his account. How many more dollars would Nathan earn after 5 years with a 10% compounded interest rate?
Answer:
Dollars earned after 5 years = $45.79
Step-by-step explanation:
Given that:
Initial money deposited in account = $75
Time for which the money is deposited = 5 years
Interest rate = 10%
Nature of interest = Simple Interest
Amount after 5 years = $112.50
To find:
Total money earned after 5 years if the interest is compounded ?
Solution:
Formula for amount if the interest is compounded annually:
[tex]A =P(1+\frac{R}{100})^T[/tex]
Where P is the principal amount (initial money)
R is the rate of interest
T is the time
Putting all the values:
[tex]A =75\times (1+\frac{10}{100})^5\\\Rightarrow \bold{A = \$120.79}[/tex]
Total more money earned or the interest after the compounding nature =
[tex]A - P[/tex] = $120.79 - $75 = $45.79
On Tuesday, the mailman delivers three checks for $5 each and two bills for $2 each. If you had a starting bank account balance of $25, what is the ending balance?
Answer:
The ending balance is $36.
Step-by-step explanation:
With the information given, in order to find the ending balance, you have to take the starting bank account balance and add the three checks that is money you receive and subtract the two bills that is money you need to pay and comes out of your account:
25+(3*5)-(2*2)=25+15-4=36
According to this, the answer is that the ending balance is $36.
The Probabilty of rolling a 1 on a 6 sided biased dice is 0.85
Answer:
false
Step-by-step explanation:
This statement is false. There are a total of 6 sides on a six-sided die therefore, every roll is a one in six chance of getting a single number since only one number can be obtained per roll. So that would mean that the probability is
[tex]\frac{1}{6}[/tex] or 0.16666 or 16.66%
That would be the actual probability of rolling a 1 on a single roll of a six-sided die, not 0.85
