The average is found by adding all the temperatures together, then dividing by the number of days.

Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.

The total for the first four days was : 56 + 60 + 79 + 70 = 265

The fifth day is 315 - 265 = 50 degrees.

What equation can be written for this graph? <br> Pls help!!!

defon

Answer:

y = 25x

Step-by-step explanation:

This is a straight line, so the formula is:

y = ax + b

a is the slope and b is the y-intercept.

Slope formula:

a = (y2 - y1)/(x2 - x1)

Select two random points from the line:

Point 1: x=2 and y=50
Point 2: x=4 and y=100

Slope a = (100 - 50)/(4 - 2) = 50/2 = 25

=> y = 25x + b

Use one of the points to find b:

50 = 25*2 + b

=> b= 0

So the equation is y=25x

anygoal [31]

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> number of tennis balls

y ----> number of tennis rackets

we know that

To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets

In this problem we have

$\frac{x}{y}=\frac{5}{3}$

see the model in the attached figure N 1

$y=\frac{3}{5}x$

$y=0.60x$

This is the equation of a linear direct variation

The relationship between the variables x and y is proportional

see the model in the attached figure N 2
