Step-by-step explanation:
<h2>=>7-2x≤0</h2><h2>=>-2x+7≤0</h2><h2>=>-2x≤-7 divide 2 by 2 and by 7</h2><h2>=>x≤3.5</h2>
Answer:
6
Step-by-step explanation:
The average rate of change is the same as the slope. Since the slope is the same no matter what interval you choose, the answer is 6.
Answer:
16 4/5
Step-by-step explanation:
1. Divide 5 3/5 by 2 (2 4/5)
2. Multiply 2 4/5 by 2 and multiply 5 3/5 by 2 (5 3/5) (11 1/5)
3. Add them together (16 4/5)
Given:
m/n-3(m+n)
m=-10 and n=-2
Solving:
-10/-2-3(-10-2) Since m=-10 and n=-2, we substitute them in for the values since they have an equal relationship.
Now, follow Orders of Operations: PEMDAS
-10/-2-3(-12) Simplify parentheses (P)
There are no Exponents (E)
Multiplication (M) and Division (D) are =, so we do whatever operation comes from the left to right.
-10/-2=5 Division comes first on the left.
therefore:
5-3(-12)
-3(12)=-36, Multiplication is last on the right.
therefore:
5-36
5-36=-31 After M/D, we do Addition and Subtraction, which are also =, so we do them left to right.
Therefore -10/-2-3(-10-2)=-31
Answer:
x = -6
Step-by-step explanation:
The value of x never changes, no matter what the value of y is, so x = -6 describes every point on the line.
