Let f(x) = x2 and g(x) = x - 3. Evaluate the expression.
(fºg)(x)
Α. χ2 -3
B. x2 - 6x + 9
C. 2x - 6
D. x2 + 6x + 9

Answers

Answer 1

Answer:

B

Step-by-step explanation:

(fºg)(x) is also f(g(x)).

Therefore:

f(x - 3)= (x-3)^2

f(x-3) = x^2 - 6x + 9

U can just search it lol

Explanation:

but for perimeter add all the side lengths.

Perimeter of a circle: To calculate the circumference, you need the radius of the circle: Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the circle.

Gayle and Rasheda left their ballet studio at the same time traveling in the same direction (along the same road). Gayle is driving at a speed of 50 mph and Rasheda at 58 mph. How many hours will it be before Rasheda is 24 miles ahead of Gayle?

Answers

Answer:

It will be uo to 3 hours before Rasheda is 24 miles ahead of Gayle

Step-by-step explanation:

From the question, we have;

The speed at which Gayle is driving = 50 mph

The speed at which Rasheda is driving = 58 mph

Let 't' represent the time at it will take for Rasheda to be 24 miles ahead of Gayle, we have;

58·t - 50·t = 24

8·t = 24

t = 24/8 = 3

The time that will have gone by before Rasheda is 24 miles ahead of Gayle, t = 3 hours.

In 2010, the population of a city was 69,000. From 2010 to 2015, the population grew by 7.1%. From 2015 to 2020, it fell by 3%. How much did the population grow from 2010 to 2015, to the nearest 100 people?

Answers

Answer:

4,899

Step-by-step explanation:

The computation is shown below:

Given that

In the year 2010, the population of the city was 69,000

From 2010 to 2015 the population would be grow by 7.1%

So, in the year 2015, the population is

= 69,000 + 69,000 × 7.1%

= 69,000 + 4,899

= 73,899

Now the growth would be

= 73,899 - 69,000

= 4,899

Solve the system of equations x + y = 4 and -9x + 7y = -84 by combining the
equations.

Answers

Answer:

x = 7

y = -3

Step-by-step explanation:

x + y = 4                 (Multiply this by 9)

-9x + 7y = -84

9x + 9y = 36

-9x + 7y = -84

16y = -48

y = -3

x + y = 4  

x - 3 = 4

If 5x + 4y= 13 and 4x + 5y = 14, find the value of (x - y).​

Answers

Answer:

x - y = - 1

Step-by-step explanation:

Given the 2 equations

5x + 4y = 13 → (1)

4x + 5y = 14 → (2)

Subtract (2) from (1) term by term , that is

(5x - 4x) + (4y - 5y) = 13 - 14

x - y = - 1

Answer:

x = 1

y = 2

x - y = -1

Step-by-step explanation:

5x + 4y= 13,   then 4y = 13 - 5x, then y = (13 - 5x)/4

4x + 5y = 14

substitute for y:

4x + 5(13 - 5x)/4 = 14

simplifying:

4x + (65 - 25x)/4 = 14

4x + 16.25 -6.25x = 14

-2.25x = -2.25

x = 1

y = (13 - 5)/4 = 2

18x+18+−10=740(Distribute)

(18x)+(18+−10)=740(Combine Like Terms)

18x+8=740

18x+8=740

Step 2: Subtract 8 from both sides.
