Answer:
A
Step-by-step explanation:
-4x-10≤2
-4x≤12 Add 10 on both sides
-x≤3 Divide by 4 on both sides
x≤-3 put a negative on both sides
Hope this helps :D Please mark brainliest if correct :D
Answer:
Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. The process entails collecting like terms, which implies adding or subtracting terms in an expression.

Answer:
3.5 (meters per second)
Step-by-step explanation:
To calculate the slope, we need two points. Let's see if we can select two points from the graph.
From the graph, we can pick out two possible points.
At the beginning, (0,2.5) is a valid candidate.
And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.
The slope formula is:

Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:

Simplify:

Thus, the slope is 3.5 meters per second.
Further notes:
And the entire equation will be:
