Answer:
x = 19
Step-by-step explanation:
To solve for x, set f(x) equal to the output value, hence
-
x + 7 = 
Multiply all terms by 3 to eliminate the fractions
- x + 21 = 2 ( subtract 21 from both sides )
- x = - 19 ( multiply both sides by - 1 )
x = 19
Answer:
(a) 30,000 + 14,000x (b) 350y (c) 350y - (30,000 + 14,000x) (d) Yes
Step-by-step explanation:
(a) Total cost = 30,000 + 3,000x + 11,000x = 30,000 + 14,000x
(b) Total revenue = 350y
(c) Total profit = Total revenue - total cost = 350y - (30,000 + 14,000x)
(d) To break even, the total profit of the school should be $0 or more. If they decide to use 5 cars with 4 students assigned to each car, 16 times a year (eight times with two sessions each) then we have a total of 20 students. Using our formula total profit is equal to 350(320) - (30,000 + 14000(5)) = $112,000 - $100,000 = $12,000 profit
Answer:
I think it's mean, range, median, and outlier

<h3><u>Given :-</u></h3>
- Here, we have given one quadrilateral that is quadrilateral ABCD
- We also have given the angles of quadrilateral that is ( 6x + 5)° , ( 9x - 10)° , 80° and a right angle
<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>
Here, we have to find the value of x
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u><u> </u></h3>
We have given quadrilateral ABCD here , whose angles are as follows
- Angle A = ( 6x + 5)°
- Angle B = ( 9x - 10)°
- Angle C = 80°
- Angle D = A right angled triangle
[ The measure of right angled triangle is 90° ]
<u>We </u><u>know </u><u>that</u><u>, </u>
- Sum of the angles of quadrilateral is equal to 360°
<u>That </u><u>is </u>

<u>Subsitute </u><u>the </u><u>required </u><u>values </u>









Hence, The value of x is 13 .

Measure of Angle A




Measure of Angle D




<u>Now</u><u>, </u><u> </u><u>we </u><u>know </u><u>that</u><u>, </u>
- Sum of angles of triangles is equal to 360°
<u>That </u><u>is</u><u>, </u>





Hence, Proved.
