Answer:
sarah is incorrect.
Step-by-step explanation:
She is incorrect because a fraction of a fraction is never going to lead to a whole number. For example, 1/3 times 1/3, you will get 1/6. The fraction will always get smaller, not bigger.
Answer:
f(-1)=3
Step-by-step explanation:
f(x)=x^2-6x+3x-1
f(x)=x^2-3x-1
f(-1)=(-1)^2-3(-1)-1
f(-1)=1+3-1
f(-1)=4-1
f(-1)=3
Answer:In the following diagram, two parallel lines are cut by a transversal. What is the value of x x? Solution: The two angles 3x −15 3 x − 15 and 2x +7 2 x + 7 are equivalent. That is: 3x −15 = 2x +7 3 x − 15 = 2 x + 7

Answer:
3
Step-by-step explanation:
= ( divide numerator/ denominator by LCM of 25 )
= ( cross- multiply )
3t = 720 ( divide both sides by 3 )
t = 240
(Short) Answer:
Because the absolute value of a number is the distance between the number and the origin of the line.
Step-by-step explanation:
Mrs. Shen writes the expression |-5| + |3| on the board. Show or explain why the sum |-5| + |3| is the distance between -5 and 3 on a number line.
The definition of absolute value:
For x = 0 or x > 0, | x | = x
For x < 0, | x | = - x
Because the absolute value of a number is the distance between the number and the origin of the line. (0, 0) -5's distance to the line is 5 and 3's distance to the origin of the line is 3. The sum of 5 and 3 is 8. Same with solving the absolute value, |-5| + |3| we get 5 + 3 which is 8 too.
