Is x=4 a solution to the equation 6=x+2? Is it a solution to the inequality 2x≥9?
jek_recluse [69]

Answer:

Is x = 4 a solution to the equation 6 = x + 2? YES

Is x = 4 a solution to the inequality 2x ≥ 9? NO

Step-by-step explanation:

Is x = 4 a solution to the equation 6 = x + 2? YES

we cans solve the equation 6=x+2 by clearing for x:

6 = x + 2

we move the +2 on the right as a -2 to the left:

6 - 2 = x

4 = x

this way we find that indeed x = 4 is a solution to 6 = x + 2.

Is x = 4 a solution to the inequality 2x ≥ 9? NO

Let's solve the inequality by clearing for x:

2x ≥ 9

we move the 2 that is multiplying on the left to divide on the right side:

x ≥ 9/2

x ≥ 4.5   ⇒ <u>x must be greater than or equal to 4.5</u>

thus, <u>4 is not a solution to the inequality</u> because 4 is less than 4.5

Mr Thomas wants to protect his garage by installing a flood barrier. He connects 2 barriers side by side. Each barrier is 9 feet
bezimeni [28]

Answer:

36 square feet,

Step-by-step explanation:

Given:

Mr Thomas wants to protect his garage by installing a flood barrier.

He connects 2 barriers side by side

Each barrier is 9 feet long by 2 feet high ( breadth)

Question asked:

What is the combined area of the barriers ?

Solution:

Length of each barrier = 9 feet

As he connects 2 barriers side by side, the length will be doubled but height (breadth) will be unchanged.

Total length of two barriers = 9 + 9 = 18 feet

Height (breadth) of the barriers = 2 feet

By using, Area of rectangle = length \times breadth

                                              = 18 feet \times 2feet = 36 square feet

Therefore, combined area of the barriers is 36 square feet,
