Answer:
I don't know what the question is but...
Step-by-step explanation:
-2t+5-13= -2t-8
-2t+5+13=-2t+18
-2t+5*13= -2t+65
-2t+5/13= -26t-5/13
Answer:
{0, 10, 42}
Step-by-step explanation:
<em>Domain is set of input values and range is set output values.</em>
For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}
<u>Range is:</u>
- f(-2) = 2(-2)² - 8 = 0
- f(3) = 2*3² - 8 = 10
- f(5) = 2*5² - 8 = 42
<u>Range:</u> {0, 10, 42}

Answer:
Fixed rate is $60.
Step-by-step explanation:
Let us consider per student charge be 'x'.
Let us consider fixed rate be 'b'
Given:
I rent a gym for $150 for 30 students.
So we can say that;
Total amount is equal to sum of number of students multiplied by per student charge and fixed rate.
framing in equation form we get;

Also Given:
another time I rent the gym for $270 for 70 students.
So we can say that;
Total amount is equal to sum of number of students multiplied by per student charge and fixed rate.
framing in equation form we get;

Now we will subtract equation 1 from equation 2 we get;

Dividing both side by 40 we get;

Now we will substitute the value of x in equation 1 we get;

So we can say that the equation can be written as;

Hence we can say that fixed rate is $60 and per student charge is $3.
