What Does C equal in
[tex]\sqrt{8c+4}[/tex]
Along with the answer, please provide an explanation on how to do the +4
Answers
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.

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.
Answers
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]

Answers
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

heolp ASAPPPPPPP!!!! Suppose three riders rode a total of 182 miles.
If they used a total of 13 horses, and rode each horse the same number of miles, how many miles did they ride before replacing each horse?
HELP NOW
They rode
__________miles before replacing each horse.
Answers
Answer:
14 miles
Step-by-step explanation:
You divide. 132/13
Which gives you 14. Every 14 miles, the riders replaced a horse.
So, They rode 14 miles before replacing each horse.
Hope this helps:)
Answer:
14 miles
Step-by-step explanation:
182/13 = 14 miles
Assuming each horse was only ridden once
then a total of 16 horses were ridden for a total of 182 miles
182 miles /13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.

What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The trinomial is given below.
⇒ 4x² + 12x + 9
Then the factor of the trinomial will be
⇒ 4x² + 12x + 9
⇒ 4x² + 6x + 6x + 9
⇒ 2x(2x + 3) + 3(2x + 3)
⇒ (2x + 3)(2x + 3)
⇒ (2x + 3)²
Then the correct option is D.

Answer ASAP!
Answers
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
