Let w = the walking time
the total time is given as 1 hr, therefore (1-w) = running time
Walking dist and running dist is the same
Write a distance equation: dist = speed * time
3w = 9 (1-w)
3w = 9 - 9w
3w + 9w = 9
12w = 9
w = 9/12 = 3/4 hrs walking back
The common endpoint is Q. The angle is: angle RQP, angle PQR, or just angle Q
You can look at the graph and see where the point crosses the y - axis for the y-int and for the x-int you look to see where the point crosses the x-axis. The coordinate with always have a coordinate of zero.
Answer:
The equation can be expressed as;
x+y=71 where,
Lengths of two equal sides=x=22 m
Lengths of longer side=y=27 m
Step-by-step explanation:
The total perimeter can be expressed as;
Total perimeter=Total length of the equal sides+total length of the longer side
where;
Total perimeter=71 m
Total length of each of the equal sides=x m
Total length of longer side=y=(x+5) m
replacing;
x+y=71...equation 1
71=(2×x)+(x+5)
2 x+x=71-5
3 x=66
x=66/3
x=22 m
y=x+5=22+5=27 m
Lengths of two equal sides=22 m
Lengths of longer side=27 m
Equation;
x+y=71
Answer:
Part a) The linear model that shows the salesperson’s total income is equal to
Part b) The total income is 
Step-by-step explanation:
Part a)
Let
k-------> the total sales for the year
y-----> the total income for the year
we know that
The linear equation that represent the situation is
Part b) we have
substitute the value of k in the linear model to find the total income
