Answer:
9 girls
Step-by-step explanation
3x+5x=24
8x=24
x=3
Now go back and replace x with 3
3(3)+5(3)=24
9+15= 24

The function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.
<h3>What is a linear function?</h3>
The term linear function refers to a function that yields a straight line graph when it is plotted. Now we know that a linear function would not contain an exponent that is greater than one.
In this case, we know that the question states that she charges a base fee of $25 and $7 for every hour she mows thus the function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.

Step-by-step explanation:
Answer:
A)Predicted value = 103.5
B)Actual value = 102
C)So, these are not same
Step-by-step explanation:
The researcher used the line to model the data.
A)When the researcher substituted the value of x = 65 into this equation, what is the resulting y value?
Substitute value x=65 in equation :
y = -0.1 x +110
y=-0.1(65)+110
y=103.5
Predicted value = 103.5
B)Based on the coordinates of the given data points, what is the actual actual vision score when x=65?
Use the given graph
When x = 65
y = 102
So, The actual actual vision score when x=65 is 102
C)When the researcher substituted x = 65 into the line of equation, is the resulting y value the predicted value or the exit value for the vision score of a 65-year-old? Use your results for parts a and b to answer this question.
Predicted value = 103.5
Actual value = 102
So, these are not same
