45x+27y=-243
-45x+10y= 95
37y= -148
y= -4
5x-12= -27
5x=-15
x=-3
This is what I got as the answer
Answer:
Slope intercept form is y = 2x-4
Step-by-step explanation:
Given equation: 2y + 2 = 4x - 6
The general form of slope intercept form is y = mx+c
2y + 2 = 4x - 6
2y = 4x - 6 -2
2y = 4x -8
dividing throughout by 2
y = 2x -4
Hence the slope intercept form is y = 2x -4
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
