Answer:
no it doesn't because if the number in the first column increase then the number in the second column shouldn't be decreasing also the constant between 85 and 5 was 17 but the constant between 10 and 79 wasn't the same
Answer:
x=3, y=4
Step-by-step explanation:
Speed = distance / time
Speed = 182.4 / 3
Speed = 60.8 miles per hour.
Answer:
5. I agree with your answer choice.
6. 13.3
Step-by-step explanation:
5. You have m∠1 = 90° = m∠2, so it is reasonable to invoke the transitive property. (Step 4 would use "angles with the same measure are congruent" to complete the proof.)
6. The difference in x-coordinates is (4-1) = 3. The difference in y-coordinates is (22-9) = 13. By the Pythagorean theorem, the distance between the points is ...
... √(3² +13²) = √178 ≈ 13.342 ≈ 13.3
If you want the x-coordinate of the solution of the system of lineare equations
<span>y - x = 9
10 + 2x = -2y
then you must eliminate y from this sytem. Rewrite the first equation: y - x = 9 becomes y = x + 9. Substitute this (x + 9) for y in </span><span>10 + 2x = -2y. y will now be gone. Solve the resulting equation for x and you'll be done.</span>
