Answer:
To find the x -intercept, set y=0 .
Therefore, the x -intercept is (−4,0) . To find the y -intercept, set x=0 .
−3x+2y↓−3(0)+2y2yy=12=12=12=6Tofindthey−intercept,setx=0.
Step-by-step explanation:
To find the x - and y -intercepts algebraically, use the fact that all x -intercepts have a y -value of zero and all y -intercepts have an x -value of zero. To find the y -intercept, set x=0 and determine the corresponding y -value. Similarly, to find the x -intercept, set y=0 and determine the corresponding x -value.
Answer:
more than 200 calls
Suppose number of calls = x
According to plan 1: Total monthly charge is $24
According to plan 2: Fix charge is $16 and $0.04 per call
cost of x's call = $0.04x
and monthly charge according to plan 2 = 0.04x + 16
a) Plan 1 is more economical than plan 2.
0.04x + 16 > 24
solve it for x
.04x > 8
x > 200
b) So, if more than 200 calls are made then Plan 1 is more economical.

Step-by-step explanation:
i took the test
Answer:
Present afe of Payal = x yrs.
Therefore, according to question,
Present age of Arav = x/3 yrs.
After 12 yrs.,
Age of Payal = (x+12) yrs.
Hence, we have,
Age of Aarav = [(x/3)+12] yrs.
If the problem says "space", that usually means that they are talking about volume. The maximum length the box can be is 8.4 inches. To find volume, you do length * width * height. You know the length and height, as well as the volume. You can replace the width with "x". Your equation should be:
11.5 * 8.4 * x = 272.8
Then you can just solve for x by dividing both sides by (11.5 * 8.4). The answer should be about 2.82 inches.
