Answer: 2/3

Step-by-step explanation: To identify the slope of this line, we first need to convert this equation to slope-intercept form.

In slope-intercept or y = mx + b form, the y

is by itself on the left side of the equation.

So our first task in this problem is to get y by itself

on the left side of the equation and we do that by

first adding 2x to both sides to get 3y = 2x + 6.

Notice that I put the x term first on the right side of the equation and then the number because in y = mx + b form, the x term comes first on the right side of the equation.

Continuing on, to get y by itself we would

divide both sides by 3 to get y = 2/3x + 2.

Now in y = mx + b form, the slope is coefficient of the x term.

So we can see that the slope of this line is 2/3.

Is the area of this 36 (2, 8), (2, 2), (–4, 2), and (–4, 8).

almond37 [142]

Answer:

yes

Step-by-step explanation:

side 1

(2,8) to (2,2)

8-2 = 6 (length of this side)

side 2

(2,2) to (-4,2)

2-(-4) = 6

side 3

(-4,2) to (-4,8)

8-2 = 6

side 4

(-4,8) to (2,8)

2- (-4) = 6

* note: it doesn't matter the order of subtraction because length can't be negative (so just make sure your answer is positive) , also don't subtract the side that is constant, you will get 0, a side can not be 0 cm

to find the area of a square multiply length by width

6 x 6 = 36

Which number completes the square? x^2-4x?

ruslelena [56]

X^2-4x=0 Let x=0 0^2=4(0)=0 0=0 [checks out] and x^2-4x=0 (4)^2-4(4)x=0 16-16=0 0=0 [also checks out]

4.Multiply both numbers on the second fraction by the bottom number of the first fraction.
5.Line both fractions up side by side with their new numbers.
6.Add together the numerators of the two fractions.
7.Take the common denominator that you figured out in Step 2 and add it on the bottom of your new numerator.
8.Put the new numerator on top and the new denominator on bottom.
9.Simplify and reduce.

Choose yes or no to tell if the fraction 2/9 will make each equation true

zmey [24]

Answer:

yes

Step-by-step explanation:

to see if 2/9 will make each equation true, you replace 'x' with 2/9, so let us do just that-

81*2/9=18

900*2/9=200

72*2/9=16

450*2/9=100

now, seeing as how every answer we've gotten matches the answers of the algebraic equations, the answer is yes 2/9 does make each equation true

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!
