9. Determine whether (-3,2) is a solution of Y = 2x +8 Y= -X+1

1 answer:

4 0

2 = 2(-3) + 8
2 = -6 + 8
2 = 2

true.

2 = 3 + 1
2 = 4

false.

this is not a solution because both equations have to be true.

The length of flag is 760 feet and width of flag is 320 feet

Solution:

A seed company planted a floral mosaic of a national flag

Since, the flag is generally of shape rectangle, we can use the formula of rectangle

Let "a" be the length of rectangle

Let "b" be the width of rectangle

The length is 440 ft greater than the width

Length = 440 + width

a = 440 + b ----- eqn 1

The perimeter of the flag is 2,160 ft

The perimeter of rectangle is given as:

Perimeter = 2(length + width)

Substituting the given values, we get

2160 = 2(440 + b + b)

2160 = 880 + 4b

4b = 2160 - 880

4b = 1280

b = 320

Substitute b = 320 in eqn 1

a = 440 + 320

a = 760

Thus the length of flag is 760 feet and width of flag is 320 feet

Write the equation of the line that passes through the points (2 , -1) and has a slope of - 3

svetlana [45]

Answer:

y=-3x+5

Step-by-step explanation:

y=mx+b

m=slope or gradient (=-3)

y=-3x+b

Add your points

(2, -1)

-1=(-3 x 2)+b

-1= -6+b

-1+6=b

b=5

y=-3x+5

The last one is a function. A rule for functions is that there can only be one x value or coordinate but there can be multiple y values or coordinates.

PLEASE HELP PLEASE I AM BEGGING YOU!!! AHHHHH!!!!!!!

Leya [2.2K]

I don't know what the "act it out" strategy is but I will try to help based on my knowledge.

Try this: Write down the numbers 1-4. Then make number combinations with 3 of those 4 numbers. See how many you can make with out repeating a combination. Even it is in a different order. How ever many combinations you can mane is your answer.

This is how I would do it.
Let me know if this helps or not.

Good Luck
