what must be added to 2x^2 - 5x - 12 in order to get 7x^2 - x - 18

Answers

Answer:

5x^2 +4x -6

Step-by-step explanation:

that is the answer

yep

Answer:

5x² + 4x - 6

Step-by-step explanation:

Subtract 2x² - 5x - 12 from 7x² - x - 18 , that is the opposite operation, that is

7x² - x - 18 - (2x² - 5x - 12) ← distribute parenthesis by - 1

= 7x² - x - 18 - 2x² + 5x + 12 ← collect like terms

= 5x² + 4x - 6

A rectangle has a perimeter of 6x^3+ 9x^2 - 10x + 5 and a length of x. Find the width of the rectangle when
the length is 21 inches.

Answers

Answer:

59330 feet

Step-by-step explanation:

If length is equal to 21 feet, then x=21

Width will be f(21)=6*(21)^3+9*(21)^2-210+5=59330 feet

The width of the rectangle with the given perimeter and length is 29,686 inches.

Given that, the perimeter of a rectangle = 6x³+ 9x² - 10x + 5 and length=x.

We need to find the width of the rectangle when the length is 21 inches.

What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Let the width of the rectangle be y.

Now, length=x=21 inches.

Thus, 6x³+ 9x² - 10x + 5 = 2(x+y)

⇒6×21³+ 9×21² - 10(21)+ 5=2(21+y)

⇒55,566+3,969-210+5=42+2y

⇒59,372=2y

⇒y=29,686 inches

Therefore, the width of the rectangle with the given perimeter and length is 29,686 inches.

9. x is directly proportional to y. When x = 4, y = 9. Write an equation
for y in terms of x.

Answers

Answer:

y = 2.25x

Step-by-step explanation:

Given x is directly proportional to y then the equation relating them is

x = ky ← k is the constant of proportion

To find k use the condition when x = 4, y = 9 , then

4 = 9k ( divide both sides by 9 )

[tex]\frac{4}{9}[/tex] = k

x = [tex]\frac{4}{9}[/tex] y ← equation of proportion

Multiply both sides by [tex]\frac{9}{4}[/tex] to clear the fraction

[tex]\frac{9}{4}[/tex] x = y , then

y = [tex]\frac{9}{4}[/tex] x , or

y = 2.25x


Line l in the xy-plane is perpendicular to the line
with equation x = 2. What is the slope of line l?

Answers

The line x = 2 is perpendicular to the x-axis.
That is to say it is vertical and it’s slope is undefined.

Line l must be horizontal so it has a slope of 0

The slope of line L is 0. Then the equation of the line L in the xy-plane will be y = 0.

What is the equation of a perpendicular line?

Let the equation of the line be ax + by + c = 0. Then the equation of the perpendicular line that is perpendicular to the line ax + by + c = 0 is given as bx - ay + d = 0. If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m.

The equation of the line is x = 2. Then the slope of the equation will be given as,

m = ∞

The slope of the perpendicular line is calculated as,

⇒ -1/m

⇒ -1/∞

⇒ 0

The slope of line L is 0. Then the equation of the line L in the xy-plane will be y = 0.

There are 1175 calories total in a Big Mac, a Grilled Chicken Sandwich and a 6-piece chicken nugget meal.
A 6-piece chicken nugget meal has half the calories of the Big Mac. The Grilled Chicken Sandwich has 200 less
calories than the Big Mac. How many calories are in each of the three food items?

Answers

Big Mac has 550 calories

Chicken Nugget has 275 calories

Grilled Chicken Sandwich has 350 calories

Total number of calories = 1175

Let the number of calories in Big Mac = x

Since the 6-piece chicken nugget meal has half the calories of the Big Mac. Therefore, the number of calories in the chicken nugget = 1/2 × x = 0.5x

Since the Grilled Chicken Sandwich has 200 less calories than the Big Mac.  This will be: = x - 200

To calculate the number of calories in each food goes thus:

x + 0.5x + x - 200 = 1175

Collect like terms

x + 0.5x + x = 1175 + 200

2.5x = 1375

Divide by 2.5

2.5x/2.5 = 1375/2.5

x = 550

Big Mac has 550 calories

Chicken nugget will have:

= 0.5x = 0.5 × 550 = 275 calories

Grilled Chicken Sandwich will be:

= x - 200

= 550 - 200

= 350 calories

In total 5 days, she has paid: 5 x $2 = $10 for the sandwiches

In total 5 days, she has paid: $50 - $10 = $40 for the comics

elena bikes 20 minutes each day for exercise write and equation to describe the relationship between her distance in miles d and her biking speed in miles per hour when she bikes at a constant speed of 15 miles per hour for the first 5 minutes then at 12 miles per hour for the last 15 minutes
​

Answers

Answer:
The equation to describe the relationship between Elena distance:
a) D = 4.34 miles, b) D = 4.25 miles and c) 12D = M + 3N miles.
Solution:
Given, Elena bikes 20 minutes each day for exercise.
We have to write an equation to describe the relationship between her distance in miles, D, and her biking speed, in miles per hour,
We know that, distance travelled = speed time
a. At a constant speed of 13 miles per hour for the entire 20 minutes
Her speed is 13 miles per hour.
Then, distance D miles = 13 miles per hour 20 minutes

b. At a constant speed of 15 minutes per hour for the first 5 minutes, then at 12 miles per hour for the last 15 minutes
Now, total distance travelled = distance travelled with 15 mph + distance travelled with 12 mph

c. At a constant speed of M miles per hour for the first 5 minutes, then at N miles per hour for the last 15 minutes
Now, total distance travelled = distance travelled with M mph + distance travelled with N mph



Hence, a) D = 4.34 miles, b) D = 4.25 miles and c) 12D = M + 3N miles.
