Point A: 60
Point B: 60
Point C: 50
Point D: 50
The distance a point is from the y axis is the absolute value of the x-coordinate, because the x-coordinate is how far (and the direction) to go from the y axis. However, because it also takes into account the direction, we have to find the absolute value of it (so it is positive), since distance has to be positive.
D(x) = 32x......ur range will be ur d(x) values and the domain will be ur x values.....where d(x) = total distance and x = gallons.
So we already know that ur car's fuel tank holds 17 gallons....therefore, ur domain has to be 17 gallons or less...but it cant be negative.
so ur domain is : 0 < = x < = 17
now for ur range....since the car only holds 17 gallons....d(x) = 32(17) = 544 miles....thats the farthest it can go...therefore it can go from 0 to 544 miles....so ur range is : 0 < = d(x) < = 544
or u could write it as : domain = (0,17) with 0 representing an empty tank and 17 representing a full tank.....and ur range = (0,544) with 0 representing 0 miles driven and 544 representing 544 miles driven
Answer:
x=-1
Step-by-step explanation:
x+1=0(squared).
x+1=0 (anything raise to the power 0 is 0
collect like terms =x=-1
therefore x=-1
B is 5, you can solve this by first finding the value of a, which is 2, and then plug it into the other equation. 8+2=10 so we must also make the other side 10. We then do 10-5=5, 5 is the value of b
