Answer:
21
Step-by-step explanation:
You add up the two people until u get the number 259
Answer:
x = 10
Step-by-step explanation:
50 = (6x - 10) rewrite it
50 = 6x - 10
+ 10 + 10 add 10 to both sides
60 = 6x you're left with 60 and 6x
60/6 = 6x/6 divide both sides by 6 to get x by itself
10 = x the answer is whatever you're left with after dividing
Answer: 5 • (2x2 - 17x - 2)
———————————————————
x - 8
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
Step 2 :
10x2 - 85x - 10
Simplify ———————————————
x - 8
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
10x2 - 85x - 10 = 5 • (2x2 - 17x - 2)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 - 17x - 2
The first term is, 2x2 its coefficient is 2 .
The middle term is, -17x its coefficient is -17 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -17 .
-4 + 1 = -3
-2 + 2 = 0
-1 + 4 = 3
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
F(x) = k*x^2
You can find k using only the first point.
28 = k*2^2
7 = k
The constant of variation is 7.
I think it’s the one in the top right? cuz the negative would cancel out the 3x then u would have the 7x • 7x aka 7x to the second power
