A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.
b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.
c) f(x) = 2.69 + 0.48(x-1)
d) domain is the x values; range is the y values
So first you would simplify 3/4(5x-3) to 3(5x-3)/4
So it would be 3(5x-3)/4+8=17
2. Subtract 8 from both sides
3(5x-3)/4=17-8
3. Then simplify 17-8 to 9
3(5x-3)/4=9
4. Multiply both sides by 4
3(5x-3)=9x4
5. Simplify 9x4 to 36
3(5x-3)=36
6. Divide both sides by 3
5x-3=36/3
Simplify 36/3 to 12
5x-3=12
8. Add 3 to both sides
5x=12+3
9. Simplify 12+3 to 15
5x=15
10. Divide both sides by 5
X=15/5
Simplify 15/5 to 3
X=3
So your answer is x=3
Answer:
0, 8
Step-by-step explanation:
To find out a distance of these numbers, you shall find out how far each number is, preferably you can use a number line for this.
The number is x
product of 3 and the x = 3x
four more = 3x + 4
