Answer:
2x+8/x^2-x-6
Step-by-step explanation:
=x^2+4x-1x-4
=(x-1)(x+4)
=x^2+2x+2x+4
=(x+2)(x+2)
=x^2-3x-1x+3
=(x-1)(x-3)
= (x-1)(x+4)/(x+2)(x+2) x 2x (x+2)/(x-1)(x-3)
= (x+4)(2)/(x+2)(x-3)

The antitoxin was heated to 90ºF before it was given to patients. It was 58º colder when it arrived in Nome. What temperature was that?
Answers
Answer:
32°F
Step-by-step explanation:
Temp. = 90°F
Original was 58° less.
90 - 58
= 32°F
Original temperature = x
But the original temperature was 58 °F colder meaning it was 58 °F less than the new one
Hence x = 90 - 58 = 32 °F
Answer = 32 °F

Kirsten is trying to find height using the volume of a cylinder formula, V=πr2⋅h . Which of the following would be a good first step in re-arranging the formula to isolate the height? A) divide both sides of the equation by h B) multiply both sides of the equation by r C) divide both sides of the equation by π D) multiply both sides of the equation by h
Answers
Answer:
C
Step-by-step explanation:
we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.
so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.
therefore, dividing both sides by pi is a good first step.
explain the steps in finding the midpoint of the points (-1,2) and (3,-6). The state the midpoint
Answers
Answer:
(1, -2)
Step-by-step explanation:
midpoint x = (x₁ + x₂) / 2
midpoint y = (y₁ + y₂) / 2
[tex](\frac{-1 + 3}{2} , \frac{2 + -(6)}{2} )[/tex]
= (1, -2)
The midpoint of the points (-1,2) and (3,-6) is (1, -2).
What is Midpoint?
To find the midpoint of numbers, add two numbers and divide by 2.
Given that;
Two points are (-1,2) and (3,-6).
Now,
Let midpoint of the points (-1,2) and (3,-6) is (x, y)
The value of x = (-1 + 3)/2
= 2/2
= 1
And, The value of y = (2 + (-6))/2
= -4/2
= -2.
Thus, The midpoint of the points (-1,2) and (3,-6) is (1, -2).

Select the correct answer. Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(7) = -1 B. g(0) = 2 C. g(-4) = -11 D. g(-13) = 20
Answers
Answer:
The correct option is;
D. g(-13) = 20
Step-by-step explanation:
The given information are;
The domain of the function, g is given as -20 ≤ x ≤ 5
The range of the function, g(x), is given as -5 ≤ g(x) ≤ 45
g(0) =-2 and g(-9) = 6
Therefore, given that the function increases from -2, to 6 as the input variable decreases from 0 to -9
Therefore, if the variable, x, decrease further, to -13, the function will likely increase further, to about 20, while in the variable, x, increases further, to 7, the function may likely decrease to about -1
Therefore, we can get either;
g(-13) = 20 or g(7) = -1
However, the domain of the function is -20 ≤ x ≤ 5, therefore, 7 is outside the domain, giving g(-13) = 20 as the only statement that could be true

Water is flowing into an inverted cone, of diameter and height 30 cm at a rate of 4 litres per minute. How long, in seconds,
will it take to fill the cone?
Answers
1st question : volume to be filled in liter ?
V cone = 1/3 x base area x h
= 1/3 x pi x r² x h
= 1/3 x 3,14 x (30:2)² x 30
= 1/3 x 3,14 x 15² x 30
V cone = 7,065 cm3 ≈ 7 dm3 ≈ 7 liters
then
we know 4 liters .............1 minute
we are looking for 7 liters............. n minute
4 x n = 7 x 1
n = 7/4
n = 1,75 min => = 1 min + 0,75x60 = 1 min and 45 sec

Chris drove his car to the movie theater. The graph below represents Chris's speed over time, from when he left his house to when he arrived at the theater. At which times did Chris most likely stop at a stoplight? A. time = 3 min, time = 10.5 min, time = 12 min B. time = 2 min, time = 11 min C. time = 0 min, time = 21 min D. time = 1.5 min, time = 6 min, time = 14 min
Answers
Answer:
B
Step-by-step explanation:
Stopping at a stoplight means that Chris's speed would be zero on the graph. The times that his speed is zero are times t = 0, t = 2 min, t = 11 min, and t = 21 min. Because the graph shows his speed from the time he left his house (at t = 0) to the time he arrived at the theater (at t = 21 min), the most likely times he stopped at stoplights are times t = 2 min and t = 11 min.

How do you use the GCF to write equivalent fractions?
Answers
Answer:
Step-by-step explanation:
To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.Oct 4, 2021
