Answer:

$\frac{3}{7}$

Step-by-step explanation:

Simplify: $\frac{5}{14} - (-\frac{1}{14}) = \frac{5}{14} + \frac{1}{14}$
$\frac{5}{14} + \frac{1}{14} = \frac{6}{14}$
$\frac{6}{14} = \frac{3}{7}$

Select the equation of the line that passes through the point (-2,3) and is perpendicular to the line on the graph. (There is a

mario62 [17]

Well your line travels parallel to the y axis. What's perpindicular to the y axis? The x axis. So all lines perpindicular to the line traveling vertically through (4, 0) are parallel to the x axis. Now we need to find the intercept of this line, which they give you as (-2, 3).

A horizontal line that passes through -2, 3? We can put this into an equation and see what happens.

y - y1 = m(x - x1)
y - 3 = 0(x - (-2))
y - 3 = 0
y = 3

At a math competition 2 students can answer 40 questions in 1 hour. At the same rate, how many questions could 5 students answer

const2013 [10]

Answer:

25 questions

Step-by-step explanation:

At a math competition 2 students can answer 40 questions in 1 hour.

Therefore, 1 student can answer in 1 hour = $\frac{40}{2}$

= 20 questions

5 students can answer in 1 hour = 20 × 5 = 100 questions

60 minutes = 1 hour

15 minutes = $\frac{15}{60}$ = 0.25 hours

5 students can answer in 0.25 hours = 100 × 0.25

= 25 questions

5 students could answer 25 questions in 15 minutes.
