Answer:
(7, 10.5)
Step-by-step explanation:
just going to use substitution here.
so you would substitute the y value in the equation x-2y=-14 with 2x-3.5.
it should look like: x-2(2x-3.5)=-14
solve the equation and you get x=7.
plug in 7 for x in either equation and you get y= 10.5.

Answer:
Correct choice is 4.
Step-by-step explanation:
Tyrone determines it takes him 58.2 minutes to travel 30 miles to work, then he travels with speed
If 1 mile = 5,280 feet, then his speed is
Since 1 minute = 60 seconds, then his speed is
The total change from the beginning of the day to the end of the day is 4 29/ 122
<h3>What is rate of change?</h3>
A rate of change is simply a rate that describes how one quantity changes in relation to another quantity.
If a is the independent variable and b is the dependent variable, then:
Rate of change = change in b/change in a
We have that;
- Beginning of the day = 30 1/ 2 = 61/ 2 points
- End of the day = 129 1/4 = 517/ 4 points
Total rate of change = 517/ 4 ÷ 61/ 2
= 517/ 4 × 2/ 61
= 517/ 2 × 1/ 61
= 517/ 122
= 4 29/ 122
Thus, the total change from the beginning of the day to the end of the day is 4 29/ 122
