in this problem we have a vertical line
The equation of a vertical line is equal to the x-coordinate of the point that passes through it
so
in this case
the equation of the line is
x=-1
Answer: It is 2.
Step-by-step explanation:
Make both equation equal to each other and solve for x, as following:
- Add like terms.
- Factor the equation.
Substitute the value of x obtained into any of the original equations to obtain the y-coordinate.
Then, this is:
Answer:
5 erasers.
Step-by-step explanation:
0.35e + 0.15p = 2.80
e + p = 12
e = 12 - p
0.35(12 - p) + 0.15p = 2.80
4.2 - 0.35p + 0.15p = 2.80
4.2 - 0.2p = 2.80
-0.2p = -1.4
-0.2p/-0.2p = -1.4/-0.2
p = 7
e = 12 - 7
e = 5
26313.96
A=p(1+(r/n))^(nt)
40000=p(1+(.07/12))^72
Answer:
575 cm
Step-by-step explanation:
5 * 100 = 500
15*5=75
500+75 = 575
