I think it’s 3 because it’s just how I think it is I’m probably not correct but I think it’s 3
1. 6 units squared
2. 1 unit cubed
Step-by-step explanation:
In a cube, all the sides of all the squares have the same length.
Therefore, to find the surface area of the cube we will find the area of one square and multiply this with the number of squares in the cube (which is 6 sides)
(1*1) * 6 = 6
= 6 units squared
The formula for volume is Length * Width * Height
1 * 1 * 1 = 1
= 1 unit cubed

Answer + Step-by-step explanation:
case 1: x ≥ 6 → f(x) = 5x - 28
5(6) - 28 = 30 - 28 = 2
Then
the point A(6 ,2) lie on the graph (line) of f
5(7) - 28 = 35 - 28 = 7
Then
the point B(7 ,7) lie on the graph (line) of f
<u><em>Graphing : </em></u>
When x ≥ 6 ,the graph of f is the ray [AB) (just connect the points A and B)
case 2: x ≤ 6 → f(x) = -5x + 32
-5(6) +32 = -30 + 32 = 2
Then
the point A(6 ,2) lie on the graph (line) of f
-5(5) +32 = -25 + 32 = 7
Then
the point C(5 ,7) lie on the graph (line) of f
<u><em>Graphing : </em></u>
When x ≤ 6 ,the graph of f is the ray [AC) (just connect the points A and C)
Answer: y = 3x + 2
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
m = (y2 - y1)/(x2 - x1)
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The line passes through (3, 11) and (5, 17),
y2 = 17
y1 = 11
x2 = 5
x1 = 3
Slope,m = (17 - 11)/(5 - 3) = 6/2 = 3
To determine the y intercept, we would substitute x = 3, y = 11 and
m = 3 into y = mx + c. It becomes
11 = 3 × 3 + c
11 = 9 + c
c = 11 - 9
c = 2
The equation becomes
y = 3x + 2
