suppose there are three consecutive intergers.if two times the first is added to twice the middle, the results is 69 minus the l
argest number. what is the largest number?
1 answer:
3 consecutive means
x, x+1, x+2
OR
x, x-1, x-2
the equation based on givens and first equation is:
2(x) + 2(x+1) = 69 - (x+2)
4x + 2 = 67 - x
5x = 65
x = 13
so the largest would be x+2 or 15

-4 < x _< 9
Step-by-step explanation:
Answer: y - 9 = 2(x - 5)
Step-by-step explanation:
Point slope form: y - y1 = m(x - x1)
substitute 5 for x1 and 9 for y1 and 2 for m
x1 = 5
y1 = 9
m = 2
you get y - 9 = 2(x - 5)
Hi Walker
d=a+b+c
Flip
a+b+c=d
Add -a to both sides
a+b+c-a=d-a
b+c=-a+d
Now add -c to both sides
b+c-c=-a+d-c
b= -a-c+d

Answer:
Step-by-step explanation:
y = 3.25x + 1.25
1.25 is y-intercept
3.25 is the slope of a graph.
If x = 0, then y = 1.25
(0, 1.25)
If x = 3, then y = 3.25(3) + 1.25 = 11
(3, 11)
