Answer:
1
Step-by-step explanation:
By gradient, if you mean the "slope" of the linear function, then you have to find two points of the graph and use the "rise over run strategy". Given two coordinates, (x1, y1) and (x2, y2) of a linear function in the form y=mx+b, the slope of the line is (y2-y1)/(x2-x1). This shows the amount of "rise", or the vertical change, and the amount of "run", which is the horizontal change. Rise/Run gives the steepness of the line. The slope can also be modeled by Δy/Δx, which is the change in y over the change in x
Plugging in the given points (0,5) and (-5,0):
(y2-y1)/(x2-x1)= (5-0)/(0-(-5)) = 5/5 = 1
Answer: You need to calculate the area of two polygonal bases, i.e., the top face and bottom face.

Answer:
Step-by-step explanation:
Then
So
Therefore
2 < x < 12,
4 < x < 21,
-1 < x < 9
0 < x < 8
x<6
From above: 4 < x < 6 --> x = 5.
Answer: B.
Answer:
4th option
Step-by-step explanation:
The points R', S', T', U' are obtained by a reflection in the line y = - 3
This is a horizontal line passing through all points with a y- coordinate of - 3
RSTU and R'S'T'U' are equidistant from this line
