What is the constant rate of change od y=4x +13

1 answer:

8 0

The rate of change (ROC) is the same as the slope of a line, which would be formed from the equation y = 4x + 13, written in slope-intercept form--y=mx+b. The <em>m</em> is your slope.

<em>m</em> = 4

DiKsa [7]

First, multiply 50*3 to get the answer in feet which is 150 ft.

Then, divide 150 ft by 60 which would be 2.5 ft per second.

Peter leaves Mitchell's house traveling 30 mph. Mitchell leaves 15 min later, trying to catch up to peter, going 40 mph, if they

Kruka [31]

Given :

Peter velocity , P = 30 mph .

Mitchell velocity , M = 40 mph .

Mitchell leaves 15 min later .

To Find :

If they drive along the same route how long will it take Mitchell to catch Peter.

Solution :

Distance covered by Peter in 15 min .

$D = 30\times \dfrac{15}{60}=7.5\ miles$

Let , time taken is x .

So , distance covered b them is equal :

$7.5+30\times x=40\times x\\\\x=\dfrac{7.5}{10}=0.75\ hours\\\\x=0.75\times 60\ min\\\\x=45\ min$

Therefore , time taken by them is 45 minutes .

Hence , this is the required solution .

The temple at the top of pyramid is approximately 24 meters above the ground, and there are 91 steps leading up the temple. How

slamgirl [31]

Answer:

13.187 meters

Step-by-step explanation:

Basically, there are 24 meters for every 91 steps: $\frac{24}{91}$

There are x meters for every 50 steps: $\frac{x}{50}$

$\frac{24}{91} =\frac{x}{50}$

Cross multiply

91x = 1200

Divide both sides by 91 to isolate the variable, x

91x/91 = 1200/91

x = 13.186813

At a hardware store a bag holds up to 1 pound of nails. Each penny nail (x) weighs 0.05 pounds and each wood nail (y) weighs 0.1

posledela

For this answer, you multiply the weight of each penny nail by x and the weight of each wood nail by y. If the bag holds one pound of nails, you would use the inequality ≤.

.05x + 0.1y ≤ 1
