Write an equation of the line that passes through (2,−5) and is parallel to the line 2y=3x+10
LenaWriter [7]

Step-by-step explanation:

Divide two on both sides to get rid of it and the make the equation in the form y = mx + c

\frac{2}{2} y = \frac{3}{2} x +  \frac{10}{2}

y = 3/2x + 5

since both lines are parallel they must have the same gradient which is 3/2

y = 3/2x + c

All you have to do now is to replace x and y with (2, -5) to find c

x = 2

y = -5

-5 = 3/2 × 2 + c

-5 = 3 + c

c = -5-3

c = -8

y  = \frac{3}{2} x  - 8

Maria wants to know what time it is, but after looking at her analog clock, notices that the numbers are all missing! She notice
VMariaS [17]

Answer:

3:00

Step-by-step explanation:

If the minute hand is pointing straight up, it means that the time is at an exact hour (ex. 1:00, 2:00, not 1:30, etc.).

If the angle between the hour and the minute hand is 90 degrees, then we know that the time is either 3:00 or 9:00.

However, because the time must be between 1:00 and 5:30, it must be 3:00.

I hope this helps!
