Answer:
You spilt up the shapes into triangles, rectangles, squares, etc
The equation for rectangles and squares is
A=l•w
(Area equals length times width)
The equation for triangles is
A=(1/2)b•h
(Area equals one half times bass times height)
Answer:
The answer is 
.
Step-by-step explanation:
Given:
X/4 + 3/5x.
Now, to find the sum of the rational expressions.
So, to solve it by adding:
Therefore, the answer is .
Answer: The function that models the distance they drive is
f(x) = 50x + 20 where x is the time in hours
reasonable domain: 0 ≤ x ≤ 3
Step-by-step explanation:
examples:
95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.
120 = 50(2) + 20 This means that after 2 more hours they will reach their destination.
There is a little ambiguity in the question. The function could be written as if they are starting out. f(x) = 50t
20 = 50(.4) At 50 mph it took .4 hours to go 20 miles.
120 = 5(2.4) The whole trip took 2.4 hours.
Answer: x ≥ -1
<u>Step-by-step explanation:</u>
4(2x - 3) ≥ 4(x - 4)
8x - 12 ≥ 4x - 16 <em>distributed 4 into 2x - 3</em>
4x - 12 ≥ -16 <em>subtracted 4x from both sides</em>
4x ≥ -4 <em>added 12 to both sides</em>
x ≥ -1 <em>divided both sides by 4</em>
Graph: -1 -------------→
Interval Notation: [ -1, ∞ )
You need to solve for x (get x by itself)
x - 18 = -5 Add 18 on both sides
x - 18 + 18 = -5 + 18
x = 13
