Answer:

<h2>x= -3</h2>

Step-by-step explanation:

- 2x + 3 = 9 \\  - 2x = 9 - 3 \\  - 2x = 6 \\  \frac{ - 2x}{ - 2}  =  \frac{6}{ - 2}

x =  - 3

Answer: x = -3

Step-by-step explanation: To solve for x, we must first isolate the term containing <em>x</em> which in this problem is -2x.

Since 3 is being added to -2x, we subtract 3 from

both sides of the equation to isolate the -2x.

On the left, the +3 and -3 cancel out and on the right, 9 - 3 is 6.

So we have -2x = 6.

Now we can finish things off by just dividing

both sides of the equation by -2.

On the left the -2's cancel and on right, 6 divided by -2 is -3.

Thus, the solution to this equation is x = -3.

Klio2033 [76]

Answer:

10 percent

Step-by-step explanation:

- Before 1997, people with a minimum FBGL of 140mg/dl were diagnosed as diabetic

- After 1997, people with a minimum FBGL of 126mg/dl were diagnosed as diabetic

- What is the proportion of people who were not considered diabetic before 1997 but are now considered diabetic (after 1997)?

140 - 126 = 14

In percentage, this proportion is = 14/140 × 100

= 10%

Hence, 10% of the people who were not considered diabetic before 1997 are now or will now be considered diabetic.

A landscaper receives a discount on each plant purchased. The original price of each plant is x dollars. The landscaper purchase
prisoha [69]

Answer:

$4

Step-by-step explanation:

Discount is a form of consideration in price or amount given to a customer on a sale of goods. It can be deduced from the question that;

The original price of each plant = $x

Number of plants purchased = 20

Price of the number of plants purchased without discount = $20x

Amount paid for the 20 plants with discount = $(20x - 80)

Thus,

The discount on the 20 plants = $80

Discount on each plant = \frac{total discount on plants}{number of plants purchased}

                                       = \frac{80}{20}

                                       = $4

Discount on each plant = $4

Therefore, each plant was discounted by $4.

Answer:

The second option

Step-by-step explanation:

The answer is negative (The blue line is below the x axis)

for all x values between -2 and -6  is a true statement

The first option is incorrect because the function is negative between -4 and -2.

The third option is incorrect because the function is negative between -3 and -2.

The forth option is incorrect because the function is positive for x < -6.
