Answer from: andrewalas88

we know that

If a point is a solution of the inequality

then

The point must satisfy the inequality

we have

y-3x+2

The solution of the inequality is the shaded area above the dotted blue line

see the attached figure to better understand the problem

Step 1

Point A(0,2)

Substitute the value of x and the value of y in the inequality

$x=0\ y=2$

y-3x+2

2-3*0+2

-------> is not true

therefore

The point A is not a solution for the inequality

See the attached figure------> the point A is not on the shaded area

Step 2

Point B(2,0)

Substitute the value of x and the value of y in the inequality

$x=2\ y=0$

y-3x+2

0-3*2+2

0-4 -------> is true

therefore

The point B is a solution for the inequality

See the attached figure------> the point B is on the shaded area

Step 3

Point C(1,-2)

Substitute the value of x and the value of y in the inequality

$x=1\ y=-2$

y-3x+2

-2-3*1+2

-2-1 -------> is not true

therefore

The point C is not a solution for the inequality

See the attached figure------> the point C is not on the shaded area

Step 4

Point D(-2,1)

Substitute the value of x and the value of y in the inequality

$x=-2\ y=1$

y-3x+2

1 -3*-2+2

1 8 -------> is not true

therefore

The point D is not a solution for the inequality

See the attached figure------> the point D is not on the shaded area

the answer is

B(2,0)

Answer from: Quest

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

Answer from: Quest

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
