I need help with this question

1 answer:

7 0

28 laps/hour

You divide 35 by 1.25, and you get 28.

Another way is to look at it as 5/4. So 35 divided by 5 gives you 7 laps per 1/4 hour. Then 7 times 4 gives you 28 laps per hour.

Find the equation of the linear function h that has h(12)=-7 and that is perpendicular to q(a)=1/2a+38.. I don’t understand how

Effectus [21]

Step-by-step explanation:

q(a) = ½a + 38

The slope of q is ½. So the perpendicular slope is -1/½ = -2.

Write h(x) in point-slope form:

h − (-7) = -2 (x − 12)

h + 7 = -2 (x − 12)

Simplify to get slope-intercept form.

h + 7 = -2x + 24

h = -2x + 17

-2x + 8 < -4x - 8

-2x < -4x - 16

2x < -16

x < -8

Find the equation of a line that passes through the point (3,5) and has a gradient of 2.

Karolina [17]

Answer:

y = 2x - 1

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 )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 6 + c ⇒ c = 5 - 6 = - 1

y = 2x - 1 ← equation of line
