Answer:
Slope (m) = 0.2 and y-intercept (b) = 3.5.
<h3>
Slope represents here the increase in snow 0.2 inches per hour and </h3><h3>y-intercept represents here the initially 3.5 inches snow was there.</h3>
Step-by-step explanation:
We are given weather equation y=0.2x +3.5 for finding the amount of accumulated snow y in inches x hours after 5 P.M. on a certain day.
We need to identify the slope and y- intercept of the graph of the equation .
Let us compare given equation y=0.2x +3.5 by slope-intercept form y=mx+b, we get
Slope (m) = 0.2 and y-intercept (b) = 3.5.

Answer:
Step-by-step explanation:
- Given quadratic equation is:
- Comparing it with , we find:
- It is given that: are roots of the given quadratic equation. So, we find the sum and the products of the roots.
- Since, one of the factors of is . Therefore, now we will find the value of which can be obtained by the following formula.
Answer:
4
Step-by-step explanation:
-3(4x +3)+4(6x +1)=43
-12x-9 +24x +4 =43
12x - 5=43
12x=43 +5
12x=48
x=48 :12
x=4
Answer:
x =11.17741935 gallons
Step-by-step explanation:
We can use a ratio to solve
62 miles 231 miles
--------- = -----------
3 gallons x gallons
Using cross products
62x = 231 *3
62x =693
Divide each side by 62
62x/62 = 693/62
x =11.17741935 gallons
Answer:
12
Step-by-step explanation:
square root of 8 = 2.82842712475
square root of 18 = 4.24264068712
4.24264068712 × 2.82842712475 = 12
