<h3>
Answer: C. y = 4x-1</h3>
=================================================
Explanation:
Each time x goes up by 1, the y value goes up by 4. The slope must be 4/1 = 4.
You can use the slope formula, picking any two points from the table, to get the same result. Let's say we used the first two rows
m = (y2 - y1)/(x2 - x1)
m = (7-3)/(2-1)
m = 4/1
m = 4
So the answer must be y = 4x-1 as its the only equation with a slope of 4.
To find the y intercept, we plug m = 4 and (x,y) = (1,3) into y = mx+b to solve for b. You can use any (x,y) pair from the table. I picked the first row
y = mx+b
3 = 4(1)+b
3 = 4+b
3-4 = b
-1 = b
b = -1
Since m = 4 and b = -1, we go from y = mx+b to y = 4x+(-1) or y = 4x-1

Answer:
Annike's bike trip started at 7:00, if she and Celia both start at the same time you would multiply Annike's average speed by Celia's average speed to find where they would have completed the same number of miles
equation: 11×14=154 14×11=154
Step-by-step explanation:
counting by 11:
11 22 33 44 55 66 77 88 99 110 121 132 143 <em><u>154</u></em>
11 × 14 = 154
counting by 14:
14 28 42 56 70 84 98 112 126 140 <em><u>154</u></em>
14 × 11 = 154
Answer:
a. √64=8
b. ∛1000=10
Step-by-step explanation:
64=8^2 Therefore, √64=8
1000=10^3 As a result, ∛1000=10
64=4^3 but each number can only be used once, so this is not possible answer.
