Answer:

1) $361.25

2) $280

Step-by-step explanation:

1) $425 * 0.85 = $361.25

If you purchase something that is 25% off then you would only be paying 85% of the cost. 85% in decimal form is 0.85

2) $350 * 0.80 = $280

Similarly, 20% off means you pay 80% of the cost. 80% in decimal form is 0.80

The equation of the line CD is (y-3)=-2(x-4). what is the scope of the line perpendicular to line CD

Delicious77 [7]

Answer:

y=-1/2x-5

Step-by-step explanation:

First we need to put (y-3)=2(x-4) in slope intercept form.

we need to do order of operations....

so we need to first do the parenthesis

x*2= 2x

2*-4= -8

y-3=2x-8

add 3 on both sides to isolate y

y= 2x-5

so now we know the y=mx+b form

this is one line...

now we need to find out what line is perpendicular.

Perpendicular lines have opposite reciprocals slopes.

y=-1/2x-5

Jacob and Sarah are saving money to go on a trip. They need at least $2000 in order to go. Jacob mows lawns and Sarah walks dogs

Paladinen [302]

Answer:

$20x+10y\ge 2000$

Step-by-step explanation:

Let x represent the number of lawns Jacob mowed and y represent the number of dogs Sarah walked.

Jacob charges $20 each time he mows a lawn, then he earns $20x for x lawns mowed.

Sarah charges $10 each time she walks a dog, then she earns $10y for y dogs walked.

In total, they will earn $(20x + 10y). They need at least $2000 in order to go on a trip, then

$20x+10y\ge 2000$

Note that $x\ge 0,\ y\ge 0.$
