Answer:
7
Step-by-step explanation:
3x – 4(x - 4) + 4 = 13
=> 3x - 4x + 16 + 4 = 13
=> - x + 20 = 13
=> - x = 13 - 20
=> - x = - 7
=> x = 7
Answer:
84cm^2
Step-by-step explanation:
P=2l+2w
We are given,
P=40cm
l=2w+2
Plug these into the first formula and solve for the dimensions,
length and width, of the rectangle:
40=2(2w+2)+2w Simplify
40=4w+4+2w
40=6w+4
36=6w
6=w OR the width is 6cm, therefore,
the length is
l=2(6)+2
l=14cm
To calculate the area of a rectangle, A=lw,
plug the length,14cm, and the width, 6cm, into this formula
A=(14)(6)
A=84cm2 OR the area of the rectangle is 84cm^2
It is the one second from the top. the line is straight (y=-3) until it hits x=-1 then it starts increasing significantly
Answer:
$6
Step-by-step explanation:
We have: The cost of a taxi ride is represented by the function c(m)=2m+4
Plug 1 mile into "m" of the function c(m)=2m+4
So, we have c (1) = 2 ˣ 1 + 4 = 6
Thus, The cost per mile of the cab is $6.
Answer:mean
Step-by-step explanation:
I would assume it’s the mean since that averages the 7 test scores it represents the data set well. Outlier and mode don’t describe a data set since they are quite unique within it.
