A quadrilateral is a four-sided two-dimensional shape. The following 2D shapes are all quadrilaterals: square, rectangle, rhombus, trapezium, parallelogram and kite.
Answer:
Standard form you can leave it as y=-6x-14
________ or. y=3x+7
-2
X) = 3 ln(x)
g(x=2) = 3 ln(2)
g(x=4) = 3 ln(4) = 3 ln(22) = 6 ln2
We have two ordered pairs:
(x,3 ln(2)) and (4,6 ln(2))
The average rate of change is the slope (m) of the secant line connecting the two points:
m = (6 ln2 - 3 ln2)/(4-2) = 3ln(2)/2 ≅ 1.04
a.
The unit can be found by doing $740/50 students. That gives us 14.8.
Hence the unit rate would be $14.80 per student.
b.
Now we use the rate to find how much money the seventh graders raised.
The rate is $14.80 per student so we do $14.80 x 60 students. That gives us 888. The seventh-grade class raised $888.
Set the number as x
x/5=1.21
Multiply by 5 on each side to cancel the 5 in the denominator.
x=6.05
Check your answer:
6.05/5=1.21
1.21=1.21
