I think it's , true , false , false . the last one is kinda tricky
Answer:
q = 6
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer: 13.74
Step-by-step explanation:
to find out the total cost we will:
13.09*(5/100)=0.65
13.06+0.65(tax)=13.74
Once you have it in that form, you just read off the values of h and k
For instance, if you had y = 2(x-3)^2 + 5, then h = 3 and k = 5. So the vertex is (h,k) = (3,5)<span />
Answer:
x = 12, sides = 23
Step-by-step explanation:
Since 
is equilateral, all three sides are equal. Therefore:
![\left[\begin{array}{l}y=2x-1\\y=5x-37\\y=x+11\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bl%7Dy%3D2x-1%5C%5Cy%3D5x-37%5C%5Cy%3Dx%2B11%5Cend%7Barray%7D%5Cright%5D)
Substituting y = x + 11:
![\left[\begin{array}{l}x+11=2x-1\\x+11=5x-37\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bl%7Dx%2B11%3D2x-1%5C%5Cx%2B11%3D5x-37%5Cend%7Barray%7D%5Cright%5D)
Solving for x:
Substituting x = 12:
Thus, <em>x</em> = 12 and the length of each side is 23.
