Answer:
y = (9/4)x + 2, given that I've assume the correct meaning of "-5x4."
Step-by-step explanation:
A parallel line has the same slope as the reference line,
The reference line is 9x-4y = -5x4, as written. I'm not sure the 4 belongs, but I'll assume it is written correctly. I'm not sure if the term -5x4 is meant to mean -5x^4, -20x or -20. I'll assume -20:
9x-4y = -20
Put the equation into standard slope-intercept form: Y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).
-4y = -9x - 20
y = (9/4)x + 5
This line has a slope of (9/4). The parallel line will have the same slope.
y = (9/4)x + b
We can find a value of b that would shift this line to include (4,7) by using this point in the equation:
y = (9/4)x + b
7 = (9/4)(4) + b
7 = 9 + b
b = 2
The equation of a line parallel to the reference line is y = (9/4)x + 2
The number (answer) is 2592.
Check your answer:
(substitute the numbers to see if they will equal 2592: <span>2^5 is 32 and 9^2 is 81)</span><span>
Now subsitute it into A^B*C^D: 32*81 is 2592.</span>
If the value is 5 and the equation is
I = 48t
then
I = 48*5 = 240
option B

Let
x--------> the number of minutes
y-------> the total liters of water sold
we know that
y=150x
Divide 7,500 by 150
=(7,500/150)=50 minutes
<u>Check</u>
For x=50 minutes
Find the value of y
y=150*(50)=7,500 liters of water sold------> is ok
<u>Find the domain</u>
The domain will be the interval------> [0,50] minutes
<u>Find the range</u>
The range will be the interval------> [0,7,500] liters of water sold
