Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.
Answer:
8 years old
Step-by-step explanation:
46 - 14 = 32 inches of growth
32 inches / 4 inches = 8 years
Answer:
200 miles
Step-by-step explanation:
80 = 40% of the trip
Divide 40% and 80 by 10
40% / 10 = 4
80 / 10 = 8
8 = 4% of the trip
100 / 4 = 25
8 x 25 = 200
The trip is 200 miles.
If you would like to know how many solutions does the system of two equations have, you can calculate this using the following steps:
x = -4y + 4 ... x + 4y = 4 /*(2)
2x + 8y = 8
____________
2x + 8y = 8
<span>2x + 8y = 8
</span>____________
0 = 0
The correct result would be infinitely many solutions.
Answer:
Step-by-step explanation:
i believe it is 4.
assuming feburary it snowed about 8.5 inches and in november it is at about the 3 in line you would subtract to get about 5.5 inches
