We know that the commercial plane travels 570 miles/hour. To find out how many miles does the plane travel, we do:
570 × 7 = 3990 miles.
Therefore, the plane travel 3990 miles.

Write each equation in slope-intercept form. underline the slope and circle the y-intercept in each equation 5x+3y=30
faust18 [17]

Answer:

The slope is

5

3

.

The y-intercept is

−

10

.

Explanation:

5

x

−

3

y

=

30

is the standard form for a linear equation. The slope-intercept form is

y

=

m

x

+

b

, where

m

is the slope, and

b

is the y-intercept. To convert from standard form to slope-intercept form, solve the standard form for

y

.

5

x

−

3

y

=

30

Subtract

5

x

from both sides of the equation.

−

3

y

=

30

−

5

x

Divide both sides by

−

If a ∝ b and a = 18 when b = 3, then find a when b = 5.
Elden [556K]

"a ∝ b" means "a is proportional to b", which in turn means there is some constant k such that

a = kb

We're given that a = 18 and b = 3, so that

18 = 3k   ⇒   k = 6

Then when b = 5, we would have

a = 6 × 5 = 30
