Answer:
65 cm
Step-by-step explanation:
A= 1/2 bh
A= 1/2 (13 cm) (4 cm)
A= 65 cm
Answer:
Linear would be fine as it doesn't decrease to under zero
and a curve graph would represent this data fine at 10818 turning point.
Step-by-step explanation:
If "a" and "b" are two values of x-coordinate, and "m" is the midpoint between them, it means the distance from one end to the midpoint is the same as the distance from the midpoint to the other end
... a-m = m-b
When we add m+b to this equation, we get
... a+b = 2m
Solving for m gives
... m = (a+b)/2
This applies to y-coordinates as well. So ...
... The midpoint between (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2)

Jennifer had (x1, y1) = (-4, 10) and (x2, y2) = (-2, 6). So her calculation would be
... midpoint = ((-4-2)/2, (10+6)/2) = (-6/2, 16/2) = (-3, 8)
Brandon had (x1, y1) = (9, -4) and (x2, y2) = (-12, 8). So his calculation would be
... midpoint = ((9-12)/2, (-4+8)/2) = (-3/2, 4/2) = (-1.5, 2)
Answer:
6.75 round to 7
Step-by-step explanation:
Answer:
12.5
Step-by-step explanation:
Step 1:
0.4 ( 3b + 10 ) = 19 Equation
Step 2:
1.2b + 4 = 19 Multiply
Step 3:
1.2b = 15 Subtract 4 on both sides
Step 4:
15 ÷ 1.2 Divide
Answer:
b = 12.5
