Yes. Two different x's can have the same y value but two different y's cannot have the same x value.
Answer:
x=2;DE,EF=9,DF=5
Step-by-step explanation:
Since DEF is isoceles, you can set the equations
x+7 and 2x+5 equal to each other
x+7=2x+5, now solve for x
-x=-2,
x=2, now plug in for each side
DE,EF=9
DF=3(2)-1=5
For example 1ft = 12in so 12 is the number that you are going to multiply so just multiply 25×12 and that is your answer
Answer:
4 1/12
Step-by-step explanation:
2 9/12 + 1 4/12 = 4 1/12
2(0.5c-1.5)-6=-2
Move all terms to the left
2(0.5c-1.5-6-(-2)=0
Add all the numbers together, and all the variables
2(0.5c-1.5)-4=0
Multiple parentheses
0c-3-4=0
Add all the numbers together, and all the variables
c-7=0
Move all terms containing c to the left, all other terms to the right
c=7
