Answer:
the possible line of best fit equation is;
y = 10x + 24
Step-by-step explanation:
Here, we want to get the approximate line of best fit
Mathematically, we have the general line of best fit as
y = mx + b
where m is the slope and b is the y-intercept
By joining the given lines, we can see that the y-intercept values fall a little below 30
This means that the possible y-intercept value is 24
Now, to get the slope value, we select any two points and use the slope equation
We can have (3,50) and (6,80)
Using the slope equation;
m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10
The equation is thus;
y = 10x + 24

Answer:
It is the letter A
Step-by-step explanation:
To find the perimeter you need to add all the sides. Since the width of the rectangle is 2 feet, you need to add it to another 2 since they have two equal sides. DO the same with 18 inches which is the length.
1 7/8 = 15/8
half of
(15/8) / 2 = 15/8 x 1/2 = 15/16
25.
The area is b * h, so
(2x + 7) * 4
which is greater than 100 units, so
(2x + 7) * 4 ≥ (don't look at =; only major) 100
8x + 28 ≥ 100
8x ≥ 100 - 28
8x ≥ 72
x ≥ 9
26.
The perimeter is 2 * (b + h), so
2 * (2x + 7 +4) = 2 * (2x + 11)= 4x + 22
which is greater than 50 units, so
4x + 22 ≥ (don't look at =; only major) 50
4x ≥ 50 - 22
4x ≥ 28
x ≥ 7
