6x - 3x + 1 = -2
3x = -3
x = -1
y = -3*-1 + 1
y = 3 + 1
y = 4
Answer:
<h2>10 </h2><h2 />
Step-by-step explanation:
Given both expression
2x+2 and
2x+2=10
the difference inlvosves basically the subtraction of one expression from the other expression.
now before we perform the subtraction operation, let us do some preprocessing.
let us equate the first and second expression to zero
2x+2=0 and
2x+2-10=0
we can now subtract
(2x+2)-(2x+2-10)=0
open bracket
2x+2-2x-2+10=0
collect like terms
2x-2x+2-2+10=0
0+0+10=0
the answer is 10
The correct answer is square root 20 units or 4.8
Hope this helped :)
<span>A. 40. The formula </span><span>y = kx² is the problem being presented y = 1,000 and x = 5. Plug in the values to solve
1000 = k * 5^2 (square 5 to get)
1000 = k*25
divide both sides by 25
1000/25 = 40
40 = k</span>
