−2(2x+3)≤26 - 2 2 x + 3 ≤ 26 ?

SashulF [63]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

$- 2 ( 2 x + 3 ) \leq 26.$

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$- 2 ( 2 x + 3 ) \leq 26$

Divide both sides by -2. We know that since 2 is negative, it'll be < (less than) 0. So, the direction of inequality will change.

$2x+3\geq \frac{26}{-2} \\$

Divide 26 by -2..we'll get the answer as -13.

$2x+3\geq -13$

Now, subtract 3 from both the sides.

$2x\geq -13-3$

Subtracting -13 by 3..we'll get the answer as -16.

$2x\geq -16$

Divide both sides by 2. We know that since 2 is positive, the direction of inequality will remain the same.

$x\geq \frac{-16}{2} \\$

Divide -16 by 2..we'll get the answer as -8.

$\huge \boxed{ \boxed{ \bf \: x\geq -8 }}$

The correct answer is ⇨ x greater than or equal to -8.

What is the greatest common factor of 20 and 30???

Ugo [173]

The greatest common factor of 20 and 30 is 10. This is because 10 is the largest number that when it is used to divide 20 or 30, it equals a whole number.

The simple way for us to solve is to write down the factors of both numbers, find the factors that match for both numbers, and see which is the largest out of those that match.

20: 1,2,4,5,10,20
30: 1,2,3,5,6,10,15,30

Using that logic, we can see that 10 is the greatest factor that the numbers share.

Find the area of a parallelogram whose base is 12cm and altitude is 8cm. Also find the other base of its corresponding altitude

lukranit [14]

Answer:

Step-by-step explanation:

Area of parallelogram = base * height

= 12 * 8

= 96 cm²

Area of parallelogram = 96

base * height = 96

base = 96/height

base = 96/16

base = 6 cm

Can x=9.4 be written in y=mx+b form?

Westkost [7]

Answer:

The given equation cannot be written in slope intercept form

Step-by-step explanation:

we know that

$y=mx+b$

Is the equation of the line in slope intercept form

where

m is the slope

b is the y-intercept

In this problem we have

$x=9.4$

This is a vertical line (parallel to the y-axis)

The slope is undefined

therefore

The given equation cannot be written in slope intercept form
