Answer: 16 feet is the width and 25 is length
Step-by-step explanation:
x*(2x-7)=400
Word problem written in numerical form^^^^
Solve for x to get 16
length = 2(16)-7= 25
Check our work
16*25=400 yay
Answer:
a) Yes, i think it does represent a proportional relationship because the prices all go up by 12$.
b) The constant of proportionality is 12.
c) The equation would be 12(t) t= tickets idrk how else to put the equation feel free to correct me if im wrong.
D) the graph would look like : on the x axis would go up by 1,2,3,4,5,6 and so on, and on the y axis, count by 12's. (ex. 12,24,36,48)
E) The cost of 7 tickets would be 84$
Step-by-step explanation:
I explained above.
Answer:
-2
Step-by-step explanation:
2x + y = 7 is the equation of the given straight line.
Let us arrange the above equation in slope-intercept form as
2x + y = 7
⇒ y = - 2x + 7 ...... (1)
The slope-intercept form of a straight line is given as y = mx + c, where, m is the slope and c is the y-axis intercept of the straight line.
Therefore, - 2 is the slope of the given straight line (1).
Hence, the slope of the line that is parallel to (1), is -2. (Answer)
{Slope of two parallel straight lines are of same value}
Value of x is 5. I remember doing this last year..
35a+45b=80
then we would do 99-80, and that gives us the value of c, 19
Answer:
The answer is E.
Step-by-step explanation:
The firm minimizing the cost of production when the input value x is 5 time bigger than y. At the point firm is making maximum profit, then firm need to preserve this ratio. Therefore when the ratio of x/y=5 is the closest ratio that the firm can minimize the cost of the production.
