One way to estimate your maximum heart rate is to subtract your age from 220. Enter a function to describe the relationship betw

een maximum heart rate y and age x.
Mathematics

Irina-Kira [14]3 years ago
6 0

Answer:

Maximum heart rate can be represented into a function as follows

let

x = age

y = Maximum heart rate

equation will be

y =220-x

for example if we take a person who is 50 years old then the maximum heart rate that person will have will be

y= 220 - 50

y = 170

This means that this is the average maximum number of times your heart should beat per minute while exercising.

How would I graph this?
elena55 [62]

y\leq 2x-5

↝ x-intercept

2x-5=0\\2x=5\\x=\frac{5}{2}

↝ y-intercept

y = -5

↝ y\leq 2x-5 means that the shade/area is below the graph as shown in the first picture.

y\leq -\frac{1}{2}x-3

↝ x-intercept

-\frac{1}{2}x-3=0\\-x-6=0\\-x=6\\x=-6

↝ y-intercept

y = -3

↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.

First picture is first inequality

Second picture is second inequality.

A small garden measures 8 ft by 7 ft. A uniform border around the garden increases the total area to 110 ft 2. What is the width
Alik [6]

Answer: 3

Step-by-step explanation:

You can answer this question by using the equation

(8+x)(7+x)=110

The x represents the width, as we do not know the area. If you simplify the equation, it becomes 56+15x+x2=110.

If you move all the terms to the left side, and rearrange it, it can become x^2+15x-54=0

This can be simplified into (x-3)(x+18)=0

This equation makes it so that x is either 3 or -18. It is not possible for a width to be -18, so the width must be 3.
