10 weeks, 10 times 2 is 20, and 5 times 10 is 50, divided by 2 is 25, add 20 to 25 which is 45
Answer:
x ≥ 7
Step-by-step explanation:
|x - 7| = x - 7
A. For each absolute, find the intervals
x - 7 ≥ 0 x - 7 < 0
x ≥ 7 x < 7
If x ≥ 7, |x - 7| = x - 7 > 0.
If x < 7, |x - 7| = x - 7 < 0. No solution.
B. Solve for x < 7
Rewrite |x - 7| = x - 7 as
+(x - 7) = x - 7
x - 7 = x - 7
-x + 14 = x
14 = 2x
x = 7
7 ≮7. No solution
C. Solve for x ≥ 7
Rewrite |x - 7| = x - 7 as
+(x - 7) = x - 7
x - 7 = x - 7
True for all x.
D. Merge overlapping intervals
No solution or x ≥ 7
⇒ x ≥ 7
The diagram below shows that the graphs of y = |x - 7| (blue) and of y = x - 7 (dashed red) coincide only when x ≥ 7.
Answer:
<em>567 miles</em>
Step-by-step explanation:
<em>(315 miles)/(5 hours) = 63 miles/hour </em>
<em>
</em>
<em>9 hours × 63 miles/hour = 567 miles</em>
Answer:
Angle 7 and angle 15
Step-by-step explanation:
- <em>Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.</em>
Alternate interior angles with angle 9 are:
<u>Transversal s, parallel lines are t and u,</u>
- Angle 9 is in pair with angle 7
<u>Transversal u, parallel lines are s and r,</u>
- Angle 9 is in pair with angle 15
