Answer:

i think its x=-12

Step-by-step explanation:

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace f(x) with 0 and solve for x.

x = −12

According to the given information multiply the integer by four, add 12 to the product, divide the sum by two, and subtract 6 from the quotient.

The correct option is A.

In both mathematics and computer programming, the order of operations refers to a set of guidelines on which operations to do first in order to evaluate a certain mathematical expression. The order of operations is a rule that outlines the proper steps to take when analyzing a mathematical equation. We can recall the PEMDAS steps in the following order:

parentheses, exponents, multiplication and division (from Left to right), addition, and subtraction (from left to right).

The term BODMAS is used in the UK (Brackets, Orders, Divide, Multiply, Add, Subtract).

BDMAS is a term used in Canada (Brackets, Exponents, Divide, Multiply, Add, Subtract).

The equation ((4x+12)2)-6 leads to the result 2x, demonstrating that the answer is in multiples of 2.

Answer:

X:X is the same as the letter J

If the mileage is more than or equal to 60 miles Company A will charge no more than Company B.

The inequality is:  50 + 0.50m ≤ 35 + 0.75m.

Given:

m = number of miles driven.

initial fee of Company A = $50

initial fee of Company B = $35

additional fee of Company A = 50 cents = $0.50

additional fee of Company B = 75 cents = $0.75

then the inequality will be,

⇒ 50 + 0.50m ≤ 35 + 0.75m

⇒ 50 - 35 ≤ 0.75m - 0.50m

⇒ 15 ≤ 0.25m

⇒ m ≥ 15 /0.25

⇒ m ≥ 60

Therefore, if the mileage is more than or equal to 60 Company A will charge no more than Company B.

The rise-over-run formula for the slope of a straight line is the basis of the high-low method.

What is slope of a straight line?

The slope of a straight line by joining two points is the rise over run formula. The subtraction between the two points of the y-coordinates is called the rise. And the subtraction between the two points of the x-coordinates is called the run. The slope can be calculated by dividing the rise by run.

The slope of a line either goes in the upward direction or in the downward direction or left direction or right direction. It determines the direction of the line. When the straight line goes in the upward direction, it means the rising line and slope is positive. When it goes in the downward direction, it means a falling line and slope is negative.

The total distance of the race = 8.91  miles

Solution :

Miles :

There are 5,280 feet in one mile. Simply divide 5,280 feet by your average stride length to learn how many steps it will take to walk a mile. If your average stride length is 2 feet, for example, it will take 2,640 steps to walk a mile.

One part of the race is 3.21 miles

another part of the race is 5.7 miles

Total :

add of both trails

Step-by-step explanation:

The percent increase in population of the city is 17%.

A percentage in mathematics is a quantity or ratio that is stated as a fraction of 100 (from the Latin per centum, "by a hundred"). A percentage lacks dimensions and has no associated unit of measurement.

For instance, 45% (written as "forty-five percent") equates to the fraction [tex]\frac{45}{100}[/tex]  .

The percentage increase is calculated by the ratio of the increase to the original value. So to calculate the percent increase in the population of a city we have to find the ratio of the increase in population to the original population.

The population of the city is given as 117,000 .

The population increased to 136890.

Increase in population=136890-117000=19890

percentage increase in population

[tex]=\frac{19890}{117000} \times 100\%[/tex]

= 0.17×100%
