U need to draw the orthonormal system to indicate
You can drive 28 miles per gallon.
462 / 16.5 = 28
28 x 16.5 = 462
Answer: x<4
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
x+3<7
Step 2: Subtract 3 from both sides.
x+3−3<7−3
x<4
Explanation: This rate means for every 1 hour she worked, she earned 12 dollars.
To find how long it took for her to earn 228 dollars, you have to:
1. Divide 228 by 12
2. Answer - 19
Julie worked 19 hours and earned $228.
Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:
5 = 2⁄7[8] + b
2 2⁄7
If you want it in <em>Standard Form</em>:
y = 2⁄7x + 2 5⁄7
- 2⁄7x - 2⁄7x
________________
−2⁄7x + y = 2 5⁄7 [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]
−7[−2⁄7x + y = 2 5⁄7]
__________________________________________________________
3 = 2⁄7 + b
y = 2⁄7x + 2 5⁄7
- 2⁄7x - 2⁄7x
_______________
−2⁄7x + y = 2 5⁄7 [We do not want fractions in our Standard Equation, so multiply by the denominator to get rid of it.]
−7[−2⁄7x + y = 2 5⁄7]
** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.
