x^2=400

substitute for y, 2y/y=(2*x/2)/(x/2)=x/(x/2)=x*(2/x)=2

400-2=398

for this problem you just multiply the 20 by 2=40
and then you add 40+3=43
which will equal
\frac{43}{20}


35.G
if you divide
58 \div 25 = 2.32
so G
\frac{58}{25}

36. C
\frac{5}{5}  = 1
so if you subtract
\frac{6}{5}  -  \frac{5}{5}
will equal

\frac{1}{5}
1 \frac{1}{5}

A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months
ddd [48]

Answer:

Difference in cash and plan = $155 - $149.50 = $5.50

Interest Rate = 3.68%

Step-by-step explanation:

Given:A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months

A food processor by cash = $149.50

Payment plan =  Down payment + $10*15 months

= $5 + $10*15

= $5 + $150

Payment plan = $155

Difference in cash and plan = $155 - $149.50 = $5.50

Now we have to find the interest rate

= (difference/original)*100

= (5.50/149.50)*100

Interest Rate = 3.68%

Part (a)

<h3>Answer: y1 and y3 are perpendicular</h3>

This is because the two slopes 2 and -1/2 multiply to -1. Perpendicular slopes multiply to -1 assuming neither line is vertical or horizontal.

=====================================================

Part (b)

Graph each line to see where they cross. The three points of intersection are

(0,4)

(2,-2)

(4,2)

The order of the points doesn't matter.

You could also form three systems of equations pairing up the equations, and solving each system. That way you can find the points of intersection. Graphing may be a better and faster route in my opinion. See the diagram below.
