Answer:
Step-by-step explanation: Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis.
You need to make a series of equations from what you are given first. I am going to use the first letter of each of the names to represent the length of that persons wire.
1/2s=2/5d
3c=s
s+d+c=6 ft
Okay. Now you can combine the first two equations knowing what s equals:
1/2(3c)=2/5d
d=15c/4
Now you have d=15c/4 and s=3c, so you can replace d and s in the third equation.
3c+15c/4+c=6
Then solve for c and plug it into the equation 3c=s to find the length of sarah's wire.
Answer:
the answer is -30
Step-by-step explanation:
| 2 4 |
| 3 -9| = ( 2 * (-9) ) - ( 4 * 3)
= - 18 - 12
= -30
Answer:
C. 3.2
If GF = 3.2 a possible measure of TS is 3.2
Answer:



This might not be correct though. I'm only in middle school lol. I am sure about the last one.
