Answer:
The cost of ride of tax per minute is $3 per minute
Step-by-step explanation:
We are given
where
C(x) is cost for a taxi ride
x is the number of minutes
we know that
slope is the rate of change of function
we can compare with linear equation formula and find slope
we get
slope =3
so,
The cost of ride of tax per minute is $3 per minute
Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
( - 4, 4) ; ( -4 , -2 ); ( 2 , - 2) would be the answer:)
Answer:
To find the area of this right triangle, Diego and Jada used different strategies. Diego drew a line through the midpoints of the two longer sides, which decomposes the triangle into a trapezoid and a smaller triangle. He then rearranged the two shapes into a parallelogram.
