write the equation of the line in slope-intercept form; The line is parallel to y=.5x+3 and passes through the point (-9, 12)

1 answer:

4 0

Y = 0.5x + 16.5

parallel so y = 0.5x + c
12 = 0.5 * -9 + c
12 = -4.5 + c
c = 16.5
y = 0.5x + 16.5

zmey [24]

It's asking you to work out how many minutes it will take to drive to a school if you're driving at a speed of 35 miles per hour (mph).

But there's a problem with the question because it doesn't tell you how far away the school is.

But this is how you are supposed to do it:

Distance ÷ 35 = answer (in hours)
Answer (in hours) × 60 = Final answer (in minutes).

It's like this because time = distance ÷ speed, and the question asks for the answer in minutes, but the unit is in miles per hour, so you multiply by 60 to get the answer in minutes.

Hope I helped :)

An orange grower find that she gets an average yield of 40 bushels per tree when she plants 20 trees on an acre of ground. Each

sdas [7]

Answer:

30 trees/acre

Step-by-step explanation:

Let n = the number of trees added to 1 acre

Let Y(n) = the yield in bushels/acre

Yield in bushels/acre = [bushels/tree] x [trees/acre]

Y(n) = (40-n)*(20+n)

= 800 - 20n + 40n - n^2

= n^2 + 20n + 800 ---------------------(1)

The n-value of the vertex ( which is a peak ) is given by the formula:

n(max) = -b/2a

Putting values from equation (1) gives us

n(max) = 10

The grower started with 20 tree/acre and adds 10 more for max yield, so she should plant: 30 trees/acre

and

Maximum yield is 900 bushels/acre.

The speedometer in Henry's car is broken. The function y = |x - 8| represents the difference y between the car's actual speed x

Alekssandra [29.7K]

The interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8

<h3>How to describe the translation. </h3>

The function is given as:

y = |x - 8|

The above function is an absolute function.

And the parent function of an absolute function is

y = |x|

When a function is translated right by h units, the new function is y = |x - h|

This means that the translation is a translation to the right by 8 units

See attachment for the graph the function.

<h3>Interpret the function and the translation in terms of the context of the situation.</h3>

The function is given as:

y = |x - 8|

This represents the difference y between the car's actual speed x and the displayed speed.

So, the interpretation of the function is that the difference y between the car's actual speed x and the displayed speed is 8

sara making punch for her party her punch bowl holds 600 ounces for 80 servings of punch write and solve an equation to find how

nlexa [21]

There are 7.5 ounces in each serving

<em><u>Solution:</u></em>

Given that, Sara making punch for her party her punch bowl holds 600 ounces for 80 servings of punch

<em><u>To find: Ounces of punch in each serving</u></em>

From given,

Number of servings = 80

Ounces in bowl = 600 ounces

Then, Ounces of punch in each serving is found by dividing the ounces in bowl by number of servings

<em><u>The formula used is:</u></em>

$\text{ Ounces of punch in each serving } = \frac{\text{Ounces in bowl}}{\text{Number of servings}}$

<em><u>Substituting the values we get,</u></em>

$\text{ Ounces of punch in each serving } = \frac{600}{80}\\\\\text{ Ounces of punch in each serving } = 7.5$

Thus there are 7.5 ounces in each serving
