Answer:
6.6 cm.
Step-by-step explanation:
The area of a trapezium A = (h/2)(a + b) where h = the height, a and b are the length of the parallel sides.
So substituting the given values in this formula:
34 = (4/2)(10.4 + b)
34 = 2(10.4 + b
34 = 20.8 + 2b
2b = 34 - 20.8 = 13.2
b = 6.6 cm.

Step-by-step explanation:
C (third graph, the parabola); To find if it is a function or not draw a vertical line on the graph. If the vertical line could never intercept the figure more than once anywhere on the graph then it is a function.
Answer: See explanation
Step-by-step explanation:
Let the number of callories that are in one cheeseburger be = x
Let the number of calories that are in one medium frys be = y
Therefore, the question can be formed into an expression as:
Jerry = 1x + 1y = 1200
Joe = 2x + 1y = 1260
x + y = 1200 ....... i
2x + y = 1260 ....... ok
Subtract equation i from ii
x = 60
Therefore, number of callories that are in one cheeseburger is 60 calories
Since x + y = 1200
60 + y = 1200
y = 1200 - 60
y = 1140 calories
The number of calories that are in one medium frys is 1140 calories
Y=5x
Y is the slope
When multiplying a variable, you don’t use a multiplication sign, it’s just 5x
