Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio langu
kodGreya [7K]

The dependent and the independent variable in the relationship y=60x are y and x respectively.

<h3>
What are Independent and dependent variables?</h3>

The Independent variables are variables whose value does not depend on any other variable. And it causes the change in other variables.

The dependent variable is those variables whose value is not independent and change in this variable is dependent on the change of the independent variable.

Given that you did 60 brush strokes in 1 minute. Therefore, the rate can be written as,

Rate = 60 strokes per minute

Now, the number of stokes in x minutes can be written as,

y = 60x

where y is the number of stokes,

x is the number of minutes

In the above relation, y is the dependent variable because its numerical value depends on time, while x is the independent variable.

Hence, The dependent and the independent variable in the relationship y=60x are y and x respectively.

-.At a fair hamburgers sell for $3.00 each and hot dogs sell for $1.50 each. The equation 3x + 1.5y = 30 describes the number of
NikAS [45]

Answer:

Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)

The graph in the attached figure

Part b) See the procedure

Step-by-step explanation:

<u><em>The questions are</em></u>

Part a) Find the intercepts and graph the function

Part b) What does each intercept represent?

Part a) Find the intercepts and graph the function

Let

x-----> the number of hamburgers

y ----> the number of hot dogs

we have

3x+1.5y=30

Remember that

The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero

so

For x=0

3(0)+1.5y=30

1.5y=30

y=20\ hot\ dogs

The y-intercept is the point (0,20)

The <u><em>x-intercept</em></u> is the value of x when the value of y is equal to zero

so

For y=0

3x+1.5(0)=30

3x=30

x=10\ hamburgers

The x-intercept is the point (10,0)

Plot the intercepts and graph the line

see the attached figure

Part b) What does each intercept represent?

The x-intercept is the number of hamburgers they can buy if they buy no hot dogs

The y-intercept is the number of hot dogs they can buy if they buy no hamburgers

What's the value of x ?
Helen [10]

the formula for the Pythagorean theorem is a squared plus b squared is equals to c squared we don't have our a so it will be 8 * 8 =64which is 64 is equals to 10 * 10 which is 100 - 64 is equals to 36 then you square root do square roots the 36 which is 6
