Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
[tex]=-5+\frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Let's compare both the procedures now:
Mariah:
[tex](-5) + 1 - \frac{3}{4}[/tex]
[tex]=(-5) - \frac{1}{4}[/tex]
[tex]=\frac{-21}{4}[/tex]
Therefore, Mariah did not start the problem correctly.
Shane:
[tex](-5) + 1 + \frac{3}{4}[/tex]
[tex]= -5 + \frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Therefore, Shane started the problem correctly.
The table represents some points on the graph of a linear function. What is the slope of the line?
Answer:
-9/2!
Step-by-step explanation:
For this one, It's a bit hard! But, using the process of elimination, you can tell, that since the Y's are going down, this is a negative slope. Since there was only two answers, and only one was negative, it's -9/2!
I really hope this helped... I know it wasn't the best, but I graphed it for you!

which of the following pairs of functions are inverses of each other
Answer:
c would be the answer you are looking for and please mark brainliest
Step-by-step explanation:
Options A and D have functions that are inverses of each other.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To check whether two functions are inverses of each other, we need to check if the composition of the functions in both orders results in the input value.
Here, we need to check if f(g(x))=x and g(f(x))=x for all values of x in their domains.
A. f(x) = 7/(x-9) and g(x) = (x+9)/7
f(g(x)) = f((x+9)/7) = 7/((x+9)/7 - 9) = 7/(x/7) = x, so f and g are inverses of each other.
B. f(x) = x/6 + 8 and g(x) = 6x - 8
f(g(x)) = f(6x-8) = (6x-8)/6 + 8 = x/6 + 8/6 = x/6 + 4/3, which is not equal to x. Therefore, f and g are not inverses of each other.
C. f(x) = 2 + ∛x and g(x) = 2 - x³
f(g(x)) = f(2 - x³) = 2 + ∛(2 - x³) ≠ x, so f and g are not inverses of each other.
D. f(x) = 5x - 11 and g(x) = (x+11)/5
f(g(x)) = f((x+11)/5) = 5((x+11)/5) - 11 = x, and g(f(x)) = g(5x-11) = (5x-11+11)/5 = x/5, so f and g are inverses of each other.
Therefore, only options A and D have functions that are inverses of each other.

Answer:
13,500
Step-by-step explanation:
Answer: 13,500
Step-by-step explanation:
So the 4 is in the hundred place than u look to the right where the next digit is which is 8. If its 5 or more u round up but if its 5 or less it stays the same. So 8 is 5 or more than u round up the 4 to 5 and leave the rest of the digit 0's. but u leave the 13 the same. If that makes sense.

Answer:
The first answer = t ≥-7
Step-by-step explanation:
If one side of an inequality is multiplied by a negative number, to find an equivalent inequality the “direction” of the inequality has to change (for example, ≥ has to change to ≤ ). Find a so that y > x is equivalent to − 3 y < a x.

Answer:
strawberries are 24/42 apples are 2/42 and oranges are 16/42
Step-by-step explanation:
Trust me i did these same exact problems!!!
Also mark me brainly if this helped!!! :)
The fraction for strawberries is 12/21, the fraction for apples is 1/21, and the fraction for oranges is 8/21.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
A platter holds 24 strawberries, 2 apples, and 16 are oranges.
The total number of fruits = 24 + 2 + 16
The total number of fruits = 42
The fraction for strawberries = 24/42 = 12/21
The fraction for apples = 2/42 = 1/21
The fraction for oranges = 16/42 = 8/21
Thus, the fraction for strawberries is 12/21, the fraction for apples is 1/21, and the fraction for oranges is 8/21.
