Answer:
(3.5, 4.8)
Step-by-step explanation:
2.6 - 1.7 = 0.9, 2.6 + 0.9 = 3.5
3 - 1.2 = 1.8, 3 + 1.8 = 4.8
Answer: nickels = 14, dimes = 42, quarters = 18
<u>Step-by-step explanation:</u>
Let n represent nickels <em>which has a value of $0.05 </em>
Let d represent dimes <em>which has a value of $0.10</em>
Let q represent quarters <em>which has a value of $0.25</em>
It is given that:
n = n
d = 3n
q = n + 4
and their total value is $9.40 ⇒ n + d + q = $9.40
Use substitution to find the quantity of nickels:
.05(n) + .10(3n) + .25(n + 4) = 9.40
5n + 10(3n) + 25(n+4) = 940 <em>multiplied by 100 </em>
5n + 30n + 25n + 100 = 940 <em>distributed</em>
60n + 100 = 940 <em>added like terms</em>
60n = 840 <em>subtracted 100</em>
n = 14 <em>divided by 60</em>
n = 14
d = 3n
= 3(14)
= 42
q = n + 4
= (14) + 4
= 18
Answer: Y=2.50x+b
Step-by-step explanation:
Thats not the whole answer, you didnt attach the graph but what you need to do is find the y-intercept and put that into b and theres your equation. The y-intercept(B) represents the initial money that joe had in his savings the 2.50x part or the slope is the money that he states he can add each week.
<h2 />
We are given
equation of line as

we will check each options
option-A:
we can plug (3,1)
x=3 and y=1


we can see that
they are not equal
so, this is FALSE
option-B:
we can plug (-1,-2)
x=-1 and y=-2


we can see that
they are equal
so, this is TRUE
option-C:
we can plug (-3,4)
x=-3 and y=4


we can see that
they are not equal
so, this is FALSE
option-D:
we can plug (2,6)
x=2 and y=6


we can see that
they are not equal
so, this is FALSE
