Answer:
Range: {-1, 0, 1}
General Formulas and Concepts:
<u>Math</u>
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
- {Set Builder Notation}
Step-by-step explanation:
<u>Step 1: Define</u>
[Relation] {(-4, 1), (-2, 0), (8, -1)}
<u>Step 2: Identify</u>
According to the relation, our y-values are 1, 0, and -1. These values would encompass our range.
Solve the question and go on from there like you were already doing.
3.33=333%
and
3/5=.6=60%
to find a percent find a decimal and move the decimal point two spaces right
<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs
distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:
Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles
Hope this helped :)</span>
200*0.75=150
250-150=100
100/1.25=80
g is greater than or equal to 80
