Answer: x=-5
2x-20=-30
x-10=-15
+10 +10
x=-5
Explanation: first, you need to divide by 2 to both sides. then, add 10 to both sides.
You should get, x=-5.
It is an irrational number. A number is rational if it can be expressed as a quotient of 2 integer numbers. Number π2 cannot be expressed as a quotient of integers, so it is an irrational number.
If the equation of the absolute value function is f(x) = |x + 1| + 7, then the range of the function is -∞ < y ≤ 7
<h3>How to determine the range of the absolute value function?</h3>
<em>The question is incomplete, so I will provide a general explanation</em>
Assume that the absolute value function is given as:
f(x) = |x + 1| + 7
Set the absolute value to 0
f(x) ≥ 0 + 7
Evaluate
f(x) ≥ 7
This means that the smallest value of the function is 7
Hence, the range of the absolute value function is -∞ < y ≤ 7

Answer:
B.76
Step-by-step explanation:
4 quarts = 1 gallon
so 4 * 19=76
Question 1
-1 / 2 = y - 1
-1 / 2 + 1 = y
y = 1 / 2
Question 2
-3π + w = 2π
w = 2π + 3π
w = 5π
Question 3
1.2m = 0.6
m = 0.6 / 1.2
m = -0.2
Question 4
q + 2.7 + -0.9
q + 2.7 = 0.9
q = 0.9 - 2.7
q = -1.8<span> </span>
