The like terms are 23y & 2y and 7x & x because they have the same variables
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x ----> the number of days
y ----> the amount of money in her bank account
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or rate
b is the y-intercept or initial value
In this problem we have
The slope is equal to
----> is negative because is a decreasing function
----> initial amount in the account bank
substitute
see the attached figure to better understand the problem
Answer:
Three angles measuring 75, 45, and 60.
Step-by-step explanation:
Yes it is a Trapezoid. First, find Perimeter (P), since it's easiest. P = sum of all 4 sides, so:
P = 9.8 + 3.5 + 6.53 + 6.33 = 26.16 yds
Lastly, we need the Area (A) of a trap., which is the average of the parallel bases (usually top and bottom) multiplied by height (h). In our case a1 & a2, and average means add them then divide by 2, so our formula becomes:
A = [(a1+a2)/2]×h
A = [(9.8+3.5)/2]×5.6
A = 37.24 sq.yds.
