Answer:
See below
Step-by-step explanation:
From the table we see there is a relation between x and y values
Every step change of x = 0.5, every step change of y = 2
<u>This relation is linear. The formula for linear function is:</u>
<u>Using to pairs of points to get the slope and y-intercept</u>
<u>Calculating the slope:</u>
- m = (64 - 60)/(1 - 0) = 4/1 = 4
- y - intercept is 60 as per point (0, 60)
<u>So the function is</u>
<h3>Part A</h3>
<h3>Part B</h3>
<h3>Part C</h3>
- Slope is the steepness of the line.
- y -intercept is the lowest score with no time spent studying
Answer: (fg)(x) = 6x^2 + 11x - 7
Explanation:
(2x - 1)(3x + 7)
= 6x^2 + 14x -3x -7
= 6x^2 + 11x - 7
Answer:
the answer is 22 common value
Answer:
Step-by-step explanation:
Please consider the complete question.
Wyatt is working two summer jobs, washing cars and tutoring. He must work no less than 12 hours altogether between both jobs in a given week. Write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours tutoring, t, that Wyatt can work in a given week.
The number of hours altogether between both jobs would be 
.
Since Wyatt must work no less than 12 hours altogether between both jobs in a given week, so hours in both jobs should be greater than or equal to 12. We can represent this information in an inequality as:
Therefore, our required inequality would be .
Answer: x=11 111.11 USD - investments at 6% interest
25000-11 111.11= 13 888.89 USD investments at 15 % interest
Step-by-step explanation:
Paul wants to have 11% from 25000 USD that is 0.11*25000=2750 USD
Let Paul invests x USD at 6% interest (which makes him 0.06*x USD yearly) and the residual amount, i.e.
25000-x at 15% interest. (Which makes 0.15*(25000-x)= 3750-0.15*x ).
So the total return per year:
0.06*x+3750-0.15*x=2750
3750-0.09*x-2750=0
1000-0.09*x=0
x=1000/0.09
x=11 111.11 USD - investments at 6% interest
25000-11 111.11= 13 888.89 USD investments at 15 % interest
