Answer:
Step-by-step explanation:
x = days, y = minutes
first day, she walked for 10 minutes......(1,10)
2nd day, she walked for 15 minutes.....(2,15)
now, we find the slope...
(1,10) , (2,15)
slope = (y2 - y1) / (x2 - x1) = (15 - 10) / (2 - 1) = 5/1 = 5
now we use y = mx + b.....we are looking for b, the y int
y = mx + b
slope(m) = 5
u can use either set of points...(1,10)...x = 1 and y = 10
now we sub and find b
10 = 5(1) + b
10 = 5 + b
10 - 5 = b
5 = b
so this equation is y = 5x + 5
so to calculate the number of minutes she walked on day 20, sub in 20 for x and solve for y
y = 5x + 5
y = 5(20) + 5
y = 100 + 5
y = 105 <=== she walked for 105 minutes
<h2>C is the correct answer!</h2><h3></h3><h3>2/5</h3><h3>9/?</h3><h3></h3><h3>2 x ? = 9</h3><h3>9 ÷ 2 = 4.5</h3><h3>2 x 4.5 = 9</h3><h3></h3><h3>5 x 4.5 = <u>22.5</u></h3>
The area is 28.26
to find the radius you have to divide the diameter by 2 which you’ll get 3
then plug it into the equation
A=3.14•3^2
Answer:
Here is a graph I created.
For Miguel to spend the least amount of money, he would have to buy 2 gallons for $5.98 and two 1/2 gallons for $4.20. The total is $10.18.
I'm stuck on the next question though.
