What Does C equal in
[tex]\sqrt{8c+4}[/tex]
Along with the answer, please provide an explanation on how to do the +4
Answer:
See below.
Step-by-step explanation:
We have the expression:
[tex]\sqrt{8c+4}[/tex]
And we want to determine the domain restrictions of the expression.
Remember that the radicand (expression under the square root) must always be positive or 0. This is because we can't take the square root of a negative (and the square root of 0 is just 0). So, to find the domain restrictions, we can write and solve for the following inequality:
[tex]8c+4\geq0[/tex]
This is saying (8c+4) must be greater than or equal to 0. In other words, it's positive or 0.
So, solve for c. Subtract 4 from both sides:
[tex]8c\geq-4[/tex]
Now, divide both sides by 8. This yields:
[tex]c\geq4/8\\c\geq -1/2[/tex]
So, our c must be greater than or equal to -1/2. If it is less than -1/2, we won't have a solution.

For a data set of weights? (pounds) and highway fuel consumption amounts? (mpg) of eight types of? automobile, the linear correlation coefficient is found and the? P-value is 0.001. Write a statement that interprets the? P-value and includes a conclusion about linear correlation.The? P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is nothing?%, which is ? low, high, so there ? is not is sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles
Answer:
The correct option is;
Low
Step-by-step explanation:
Given that the P-value of the linear correlation = 0.001, we have that the P-value is a demonstration that a linear correlation that has a value in the range of the given correlation is ,most arguably very low
From the z-table, a P-value of 0.001 corresponds to a z-value of -3.09, we have that in a normal distribution since 95% of the scores have a z-score of between -2 and 2, the z-score of -3.09 is very distant from the mean and having a low value, whereby the P-value shows that the likelihood of finding another linear correlation that is as far from the mean as the given correlation is very low.
At her birthday party, Ms. Willow would not give her age directly. She said, 'If you add the year of my birth to this year, subtract the year of my 25th birthday and the year of my 55th birthday, and then add my present age, the result is 58.
Answer:
69 years
Step-by-step explanation:
Given that:
Let year of birth = x
This year = 2020
Year of 25th birthday = x + 25
Year of 55th birthday = x + 55
Present age = 2020 - x
Hence,
x + 2020 - (x + 25 + x + 55) + (2020 - x) = 58
x + 2020 - (2x + 80) + (2020 - x) = 58
x + 2020 - 2x - 80 + 2020 - x = 58
-2x + 4040 - 80 = 58
-2x + 3960 = 58
-2x = 58 - 3960
-2x = - 3902
x = 1951
Birth year = 1951
,
Hence, age =
2020 - 1951 = 69 years

Solve by factoring:
x² – 5x - 14=0
O A. x = 7,X = -2
B. x = -7, x = 2
O C. x = -1, x = 14
O D. x=-14, x = 1
Answer ASAP!
Answer:
A
Step-by-step explanation:
Given
x² - 5x - 14 = 0
Consider the factors of the constant term (- 14) which sum to give the coefficient of the x- term (- 5)
The factors are - 7 and + 2, since
- 7 × 2 = - 14 and - 7 + 2 = - 5, thus
(x - 7)(x + 2) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 2 = 0 ⇒ x = - 2
Answer:
A. x=-7, x=2

Write an equation of the line passing through the points (3,8) and (-2,-22)
Answer:
y=6x+8 or y=6x-22
Step-by-step explanation:
use the equation y=mx+b
m is the slope and b is the y-intercept
to find the slope use the equation m = y2-y1 over x2-x1
-22 - 8 / -2 - 3 = -30 / -5 = 6
6 is your slope and for the y-intercept you can choose whichever y-intercept to put into the equation.

A scale drawing of a school bus has a scale of 12 inch to 5 feet. If the length of the school bus is 412 inches on the scale drawing, what is the actual length of the bus? Explain or show your reasoning. A scale drawing of a lake has a scale of 1 cm to 80 m. If the actual width of the lake is 1,000 m, what is the width of the lake on the scale drawing? Explain or show your reasoning.
Answer: Actual length of the bus = 171.67 feet
Width of the lake on the scale drawing = 12.5 inches
Step-by-step explanation:
Given : A scale drawing of a school bus has a scale of 12 inch to 5 feet.
i.e. 12 inch = 5 feet
[tex]\Rightarrow \text{ 1 inch}=\dfrac{5}{12}\text{ feet}[/tex]
If length of school bus on scale drawing = 412 inches
Then, Actual length of bus = [tex]\dfrac{5}{12}\times412=171.67\ \text{feet}[/tex]
A scale drawing of a lake has a scale of 1 cm to 80 m.
If the actual width of the lake is 1,000 m
then, the width of the lake on the scale drawing = [tex]\dfrac{1000}{80}=12.5\text{ inches}[/tex]

0.4 = -9.8 -y + 2.8y
Answer: [tex]y=5.666667[/tex] or [tex]y=5 \frac{6}{9}[/tex] in fraction
Step-by-step explanation:
1. Simplify -9.8-y+2.8y to -9.8+1.8y
0.4=-9.8+1.8y0.4=−9.8+1.8y
2. Regroup terms
0.4=1.8y-9.8
3. Add 9.8 to both sides.
0.4+9.8=1.8y
4. Simplify 0.4+9.8 to 10.2
10.2=1.8y
5. Divide both sides by 1.8
[tex]\frac{10.2}{1.8} =y\\[/tex]
6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667
5.666667 = [tex]y[/tex]
7. Switch sides.
[tex]y=5.666667[/tex]
