Answer:
a. y=x+1
b. x=-3
Step-by-step explanation:
a. slope= (6-4)/(5-3)=1
substitute (5,6) to y=1x+b; b=1
therefore, y=x+1
b. x=-3
Answer:
the repayment amount would be $1,800.
he pays 300 dollars more than he borrowed.

Answer:</h3>
7.8%
<h3>
Step-by-step explanation:</h3>
In 5 days' time, the amount remaining is 0.6^5 = 0.07776 times the original amount. Since both people start with the same amount the amount remaining in Noelle's body will be this fraction of that in Karey's body after 5 days have passed.
0.07776 ≈ 7.8%
A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
Equation Of Line means A straight line on the coordinate plane can be described by the equation. y = mx+b. where m is the slope of the line and b is the intercept.
N+d=21
5n+10d=170
so
multiply first equation by -5 and add to other one
-5n-5d=-105
<u>5n+10d=170 +</u>
0n+5d=65
5d=65
divide both sides by 5
d=13
sub back
n+d=21
n+13=21
minus 13 both sides
n=8
