Answer:

B) (2,-8) : ) this was on usatestprep

Step-by-step explanation:

2, -8)

y = 4 - 6x

-8 = 4 - 6(2)

-8 = 4 - 12

-8 = -8

The point (2, -8) satisfy the equation.

In this equation y= -8 and x=2. So c would be the correct answer
y=4-6x
y=4-12
y= -8

What is -4/3 on this? Say all that apply (5 stars and brainliest for best answer)

Aleks04 [339]

Answer:

Rational Numbers

Step-by-step explanation:

- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.

- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.

- -4/3 is not a natural number as it is both a decimal and negative.

- -4/3 is not irrational because it repeats when in decimal form.

- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.

Therefore, it would apply to the first square.

Thanks!

You are building a dining room table for family dinners. The table has a length of 3x + 1 feet and a width of 3x - 1 feet. If th

igor_vitrenko [27]

Answer:

Length 7 feet and Width 5 feet

Step-by-step explanation:

we know that

The area of the rectangle ( a dining room table) is equal to

$A=LW$

where

$L=(3x+1)\ ft$

$W=(3x-1)\ ft$

$A=35\ ft^2$

substitute

$35=(3x+1)(3x-1)$

Apply difference of squares right side

$35=9x^2-1$

$9x^2=36\\x^2=4\\x=\pm2$

Remember that the length cannot be a negative number

x=2

Find the length

$L=(3(2)+1)=7\ ft$

Find the width

$W=(3(2)-1)=5\ ft$

Nico, Aditi, Erick, Raj, and Sandra are solving the equation.

Alex777 [14]

Answer:

Nico, Raj and Sandra are correct

Step-by-step explanation:

we have

$\frac{2}{5}(5+x)=8$

Method 1

Solve for x

That means ----> isolate the variable x

we have

$\frac{2}{5}(5+x)=8$

Multiply by 5/2 both sides

$(\frac{5}{2})\frac{2}{5}(5+x)=(\frac{5}{2})8$

$5+x=20$

subtract 6 both sides

$5+x-5=20-5$

$x=15$

Method 2

Solve for x

That means ----> isolate the variable x

we have

$\frac{2}{5}(5+x)=8$

Multiply by 1/2 both sides

$(\frac{1}{2})\frac{2}{5}(5+x)=(\frac{1}{2})8$

$\frac{1}{5}(5+x)=4$

Multiply by 5 both sides

$(5)\frac{1}{5}(5+x)=(5)4$

$5+x=20$

subtract 6 both sides

$5+x-5=20-5$

$x=15$

Method 3

Solve for x

That means ----> isolate the variable x

we have

$\frac{2}{5}(5+x)=8$

Apply distributive property left side

$\frac{2}{5}(5)+\frac{2}{5}(x)=8$

$2+\frac{2}{5}(x)=8$

subtract 2 both sides

$2+\frac{2}{5}(x)-2=8-2$

$\frac{2}{5}(x)=6$

Multiply by 5/2 both sides

$(\frac{5}{2})\frac{2}{5}(x)=(\frac{5}{2})6$

$x=15$

therefore

Nico, Raj and Sandra are correct

Sum of all exterior angles = 360°.

Number of sides = 360 ÷ 40 = 9

Each interior angle = 180 - 40 = 140°.

Answer: The regular polygon has 9 sides and each of its interior angles 140°
