On a road trip,drove at a speed of 60 miles per hour for the first two hours. She then increased her speed by 25%. How fast was

love history [14]

This can either be done by multiplying with 125% (1.25) or, by dividing by dividing on 4 and adding a part.

This is the easiest way, tho.

60*1.25=75

The correct answer is 75 mph.

Hey can you please help me posted picture of question

MAXImum [283]

The correct answer is option B

(5 + 3i)(4+ 2i)

= 5(4+2i) + 3i(4+2i)

= 20 +10i + 12i +6i²

= 20 +22i +6(-1)

= 20 + 22i - 6

= 14 + 22i

Find the equation in standard form of the line passing through the points (2,-3) and (4,2)

mario62 [17]

The line passes through (2,-3) and (4,2).

Calculate the slope of the line.
m = (2+3)/(4-2) = 5/2

The equation of the line is therefore
$\frac{y-2}{x-4} = \frac{5}{2}$

Cross multiply.
2(y-2) = 5(x-4)
2y - 4 = 5x - 20
2y = 5x - 16
Rewrite as
5x - 2y = 16

Answer: C. 5x - 2y = 16
