Yeah that’s the correct answer
Answer:
13. A
14. C.
Step-by-step explanation:
A relation is a function if there is only one y assigned to each x.
That is if you have a set of points, there should be no repeated x value.
So looking at {(0,0),(-2,4),(-2,-4),(-3,7)} this is not a function because you have two x's that are the same. A.
The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.
The y-intercept is where the graph goes through the y-axis at. It goes through at -1 so b=-1.
The slope is rise/run. So starting from the y-intercept (0,-1) we need to find another point to count the rise & run to... How about (3,1)? That works. You can do the counting if you want. You could also use the slope formula.
To use the slope formula, I just like to line the points up vertically and subtract vertically then put 2nd difference over the 1st difference.
(0,-1)
-(3,1)
--------
-3 -2
So the slope is -2/-3 or just 2/3.
So the equation is y=2/3 x-1
C.
Answer:
35 square inches
Step-by-step explanation:
The formula is bh
b being base and h being height. In this, the width is height and length is base.
5 times 7 is 35

Answer:
actual rate of interest is 2.08 %
Step-by-step explanation:
Given data
borrowed = $2100
time = 15 months
rate = 2.6%
to find out
interest and receive from the bank and actual rate of interest
solution
we know bank discounted the loan at 2.6%
so interest will be 2.6% of $2100
that is = 2.6/100 × 2100
interest = $54.60
so receive from the bank is borrowed money - interest
receive = 2100 - 54.60
receive from the bank is $2045.40
and we can say that interest is directly proportional to time
so interest of 12 months / interest of 15 month = 12 month time/ 15 month time
here interest of 12 months = 12/15 × interest of 15 month
interest of 12 months = 12/15 × 54.60
interest of 12 months is $43.68 (annually)
now we can calculate actual rate of interest
that is = interest / borrowed money × 100
actual rate of interest = 43.68/2100 × 100
actual rate of interest is 2.08 %
