Answer:
y = 5.18
Step-by-step explanation:
replace x in the equation with 3.5
y = -0.72x + 7.7
y = -0.72(3.5) + 7.7
y = -2.52 + 7.7
y = 5.18
X=-1
-1x2 + 5x-1 +7 = 0
-7+7 =0
0=0
Your answer: 2/3/2/9 = 0.037037037037037
Answer:
78 79 80
Step-by-step explanation:
Let the smallest number = x
Let the next number = x + 1
Let the largest number = x + 2
x + x + 1 + x + 2 = 237 Add together to get the equation
3x + 3 = 237 Subtract 3 from both sides.
3x + 3 - 3 = 237 - 3 Combine the right
3x = 234 Divide by 3
x = 234/3
x = 78
The smallest number is 78
The next number 79
The highest number is 80
