The answer is 53 because if you think about it
Which ordered pair is a solution of the equation y=x-2?
Simply plug in the numbers. We'll start with the first one (3,1). Y = 1, and X = 3, so 1 = 3 - 2.
3 - 2 = 1, which makes the ordered pair (3,1) a solution to the equation.
For the next one, do the same thing, just plug in your options.
y = 4x
We will do (-4,-1) first. So plug those in to the equation y = -1 and x will = -4
-1 = 4*-4, which would be -1 = -16, which isn't a solution to the ordered pair. Let's try (-1,-4).
y = -4, x = -1
-4 = 4*-1, which would = -4. Which is the solution to our equation! So the answer would be (-1,-4).
For the last one, do the SAME thing again.
y = -7x + 2
Plug in (8,-54) into the equation
-54 = -7*8 + 2
-7 * 8 = -56
-56 + 2 = -54
Which would make the solution (8,-54) the solution to the equation.
1. Balance after 1 year with simple interest= 600 + (2.5 x 12) = 600 + 30 = $630
2. Balance after 1 year with compounded interest = P ( 1 +
= 600 ( 1 + = 600 (1.0511) = $630.66 = approx. $630
Answer:
g = ( x - 2 ) / 3
Step-by-step explanation:
x = 3g + 2
subtract 2 from each side
x - 2 = 3g + 2 - 2
simplify
x - 2 = 3g
Divide each side by 3
(x - 2)/3 = 3g/3
Simplify
( x - 2 ) / 3 = g
Flip equation
g = ( x - 2 ) / 3
And we are done!
Answer:
x=7
y=-1
Step-by-step explanation:
x=-9y-2--------(1)
4x-3y=31
4x=31+3y
x=31/4+3/4y-------(2)
x=-9y-2=31/4+3/4y
-9y-3/4y=31/4+2
-39/4y=39/4
y=-1
substitute in 1
(-9*(-1))-2=x
x=7
