SO I HAVE A WHOLE LOT OF HOME WORK AND NEED HELP REALLY FAST. I WOULD APPRECIATE THE HELP BECAUSE I HAVE NO IDEA WHAT TO DO!
State whether each equation or function is linear. Write yes or no. If no, explain your reasoning.
1.h(x)=23
2.y=2/3x
3.y=5/x
4.9-5xy=2
write each equation in standard form. Identify A, B, and C.
5.y=7x-5
6.y=3/8x+5
7.3y-5=0
8.x=-2/7y+3/4
find the x-intercept and the y-intercept of the graph of each equation. Then graph the equation.
9.y=2x+4
10.2x+7y=14
11.y=-2x-4
12.6x+2y=6
13. The equation y=2.54x gives the length in centimeters corresponding to a length x in inches. What is the length in centimeters of a 1-foot ruler?
for meg's long distance calling plan, the monthly cost C in dollars is given by the linear function C(t)=6+0.05t, where t is the number of minutes talked.
14.What is the total cost of tslking 8 hours? of talking 20 hours?
15.What is the effective cost per minute(the total cost divided by the number of minutes talked) of talking 8 hours? of talking 20 hours?
