Answer:
a. Yes
b. Yes
c. Yes
d. No
Step-by-step explanation:
a. Because -10x+4x=6x
b. 2(12-3x)=2*12-2*3x=24-6x
c. 24 and -6x just switched places.
d. 24x-6x=18x not 24-6x
1. The range of a function is the set of all values that f can produce for all the x-es in the domain.
2. If we are given the graph, in order to find the range, we project the graph into the y axis. Informally, we draw the "shadow" of the graph into the y axis as in the FIGURE atached.
3. The range is <span>D || {y | −5 ≤ y ≤ −1}</span>
Ans
c=9
Step-by-step explanation:
2 x 9 = 18 +9 = 27
0.48 miles
Step-by-step explanation:
Step 1
It is given that the grade(slope) is 4%. This means that for every 100 miles traveled, the elevation changes by 4 miles.
Step 2
Hence for a distance of 12 miles , the elevation changes by 12*4/100 = 48/100 = 0.48 miles. [Using direct proportion]
From cm to km you divide the number by 100000
So 35,000/100000 = 0.35km
