y=4x+0 I hope that's what you were looking for
Step-by-step explanation:
Answer:
The answer is A. You just have to plug in.
Step-by-step explanation:
5x - y/3= 13
(2,-9) and (3,-6)
5(2) - -9/3 = 13
10 + 3 = 13
13 = 13 (true)
5(3) - -6/3= 13
15+ 2 = 13
17 = 13 (wrong)
Answer:
$220
Step-by-step explanation:
Make a proportion
We know that 99 over some number (x) must equal 45%
99/x=45/100
Cross multiply
45x=9,900
Divide by 45 on both sides
x=220
So, the tablet costs $220
Hope this helps! :)
Answer:
Step-by-step explanation:
I(x)=P(13x) = 2(13x)²+3(13x) +4
I(x)=P(13x).= 338x²+39x+4
Answer:
The temperature in degrees after 9 hours is -1.25 degrees Fahrenheit
Step-by-step explanation:
Here, we want to know the temperature after 9 hours
Per hour rise each hour is 3/4 degree = 0.75 degree
In 6 hours that will be 0.75 * 6 = 4.5 degrees
Or hour drop is 1/4 = 0.25 degree
In 3 hours, that will be 0.25 * 3 = 0.75 degree
Since it is a drop, we have -0.75 degree
Temperature after 9 hours will be;
-5 + 4.5 -0.75
= -5.75 + 4.5 = -1.25 degrees fahrenheit
