Answer:
21 and 22
Step-by-step explanation:
let the 2 consecutive numbers be n and n + 1, then
(n + 1)² - n² = 43 ← expand (n + 1)² using FOIL
n² + 2n + 1 - n² = 43 ← collect like terms on left side
2n + 1 = 43 ( subtract 1 from both sides )
2n = 42 ( divide both sides by 2 )
n = 21
Thus the numbers are 21 and 22

Answer:
y = -x +3
Step-by-step explanation:
The point-slope form can be a useful place to start.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
You require the line ...
y -(-4) = -1(x -7)
y = -x +7 -4 . . . . . . . . eliminate parentheses, add -4
y = -x +3 . . . . . . . . . slope-intercept form
Answer:well for the first one I am not sure but I think that since four is over the x there should be 4/x + 3 so tragically I don’t know the answer but I think it should be 12 the x should be 12 because 4x3=12 so yea 12
Step-by-step explanation:and for the other one I don’t know but ima try it should be two because 2x2=4 and so y=1-2x2-4 that’s what I think sorry. I got it wrong and do good on your test for me please
