Consecutive integers are 1 apart
they are
x,x+1,x+2
they have a sum of 51
x+x+1+x+2=51
3x+3=51
minus 3 both sides
3x=48
divide both sides by 3
x=16
16+1=17
16+2=18
the numbers are 16,17,18
1: Solve for either x or y in one of the equations. So x + y = -1 is y = -x -1
2: substitute the new equation in the opposite equation. So x - (-x - 1) = 7
3: distribute the negative. X + x + 1 = 7
4: combine like terms. 2x + 1 = 7
5: solve for x. Subtract 1 on both sides. 2x = 6
6: divide by 2 to get x by itself. X = 3
7: plug the new value of x into one of the ORIGINAL equations. 3 + y = -1
8: solve for y. Subtract 3 on both sides.
Y = -4
9: the solution is written as (x,y) so the solution would be (3, -4)
Answer:
f(3) = - 9
Step-by-step explanation:
To evaluate f(3) , substitute x = 3 into f(x) , that is
f(3) = - (3)² = - 9
