Line c has an equation of y=-3/4x-3. Line d is parallel to line c and passes through the points (-2, -2). What is the equation o

blagie [28]

Answer:

y = $\frac{3}{4}$ x - $\frac{7}{2}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{3}{4}$ x - 3 ← is in slope- intercept form

with slope m = - $\frac{3}{4}$

Parallel lines have equal slopes , then

y = - $\frac{3}{4}$ x + c ← is the partial equation of line d

to find c substitute (- 2, - 2 ) into the partial equation

- 2 = $\frac{3}{2}$ + c ⇒ c = - 2 - $\frac{3}{2}$ = - $\frac{7}{2}$

y = - $\frac{3}{4}$ x - $\frac{7}{2}$ ← equation of line d

In a class of all girls, 22 of the 28 students have brown hair. What is the

Verdich [7]

Answer:

$\frac{3}{14}$

Step-by-step explanation:

Total Students = 28

Brown Hair = 22

NOT Brown Hair = 28 - 22 = 6

The probability of an event is the number of that event divided by total number.

So, let denote probability of without brown hair be P(NOT BROWN). So, we can say:

P(NOT BROWN) = 6/28

Reducing, we get:

P(NOT BROWN) = 3/14

Emily bikes 18 miles in 2 hours. Ella bikes 22 miles in 2.5 hours. Which rate is better?

DaniilM [7]

By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.
