Answer:
x = 16° z = 67°
Step-by-step explanation:
9x - 77 + 7x + 1 = 180
16x = 256
x = 16°
z = 16 x 9 - 77
z = 67°
20/5=4 (to find a fifth of 20 apples)
4x2=8 (to find what 2 fifths is)
He used 8 apples
the correct options are:
- The function has a domain of all real numbers.
- The function has a range of {y|–Infinity < y < Infinity} (this is the same as saying that the range is the set of all real numbers.
<h3>
Which statements are true about the function?</h3>
Here we have the function:
First, this is a cubic root, so its domain is the set of all real numbers (same for the range). And we know that the cubic root is an increasing function, so if we put a negative sign before it, we will have a decreasing function.
Then the correct options are:
- The function has a domain of all real numbers.
- The function has a range of {y|–Infinity < y < Infinity} (this is the same as saying that the range is the set of all real numbers.
The fourth option is incomplete, so we can't conclude if it is true or not, it would be true if it said:
"The function is a reflection over the x-axis of y = ∛x"

A unit rate is a quantity per one unit. For example, miles per hour (mi/h). The "one unit" is 1 hour.
However, 10 miles per 2 hours (10 mi/2h) would not be a unit rate because it is per 2 hours, not 1. The unit rate for 10 mi/2h would be 5 mi/h.
You can find the unit rate by simply dividing the numerator by the denominator. (The fraction bar is a division bar!)
In simplifying 10 mi/2h, I divided the numerator (10mi) by the denominator (2h).
<span>10 divided by 2 is 5, so the unit rate is 5 mi/h.</span>
Answer with Step-by-step explanation:
We are given that a function
Assign each whole number to its largest place value digit.
We have to find the value of x that makes the equation 7 a true statement.
When f(x)=7
Then, the possible values of x are 7,127,27,257,... .
Because f(7)=7
f(127)=7
f(27)=7
f(257)=7
Therefore, the value of x =7,127,257,27,..
