That comes out to 3x^2 + 4x - 6 Answer
90+70= 160
Then 180-160=20
So angle A is 20
Answer:
So, how do we check to see if two functions are inverses of each other? Well, we learned before that we can look at the graphs.
Step-by-step explanation:
Remember, if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
This is basically the same as the other question you posted, just with different variables!! make another proportion
252 dollars/18 hours = x dollars/7 hours
252/18 is 14, so
14 = x dollars/7 hours
multiply both sides by 7 to isolate x
98 dollars = x
so john will make $98 for 7 hours of work
Answer:
Last option; x = 1 or x = -5
Step-by-step explanation:
1. Simplify the equation.
Step 1: Add 7 to both sides.
Step 2: Divide both sides by 4.
2. Now that we simplified the equation to this, we have to solve for absolute value. We know either
or
.
3. (Solving for 1st possibility)
Step 1: Subtract 4 from both sides.
Step 2: Divide both sides by 2.
4. (Solving for 2nd possibility)
Step 1: Subtract 4 from both sides.
Step 2: Divide both sides by 2.
5. Now that we have the outcomes of both of our possibilities as x = 1 or x = -5, the last option matches with what we got.
