Let GG represent the amount of money Grayson has saved tt weeks after the beginning of the year and let JJ represent the amount of money Jacob has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the who has more money saved after 18 weeks.

Answers

Answer:

The will have the same amount $ 387

Step-by-step explanation:

Grayson: y = 19x + 45

Jacob: y = 16x + 90

Grayson: y = 19(18) + 45

342 + 45 = $387

Jacob: y = 16(18) + 90

288 + 90 = $378

What is the length of the line segment with endpoints (10.8, −5.3) and (−15.6, −5.3) ?

Answers

Step-by-step explanation:

since both points are on the same horizontal line (same y coordinate), we can save the detour via the Pythagoras approach. we only need to look at the difference of the x coordinates to get the distance :

10.8 - -15.6 = 10.8 + 15.6 = 26.4

going up and down changes the y (second number in parentheses)

going to the left by 9 means all the first numbers are going in the negative direction (-9)

going up by 12 means the second numbers are going in the positive direction (+12)

take all x values and add -9, take all y values and add 12

Given: 2PQ = PR

Statement: 2PQ = PQ + QR
Reason: ???

Answers

Answer:

Given: 2PQ = PR

Prove: Q is the midpoint of line PR

Statement: 2PQ = PQ + QR

Step-by-step explanation:

If Q is the midpoint of PR then

PR = PQ + QR [by segment addition postulate]

2PQ = PR [given]

2PQ = PQ + QR

2PQ-PQ = PQ + QR-PQ [by subtracting PQ from both sides]

PQ = QR

[tex] \because[/tex] Q lies on PR and PQ = QR

[tex] \therefore[/tex] Q is the midpoint of PR
