Determine the solution to f(x) = g(x) using the following system of equations: (5 points) f(x) = 3x − 23 g(x) = −4.5x + 7

jeka94

Answer:

(The solution is (4, -11).

Step-by-stp explanation:

Let f(x) = g(x) = y:

y = 3x − 23

y = -4.5x + 7 Subtract the second equation from the first to eliminate y:

0 = 7.5x - 30

7.5x = 30

x = 4

Plug this into the first equation:

y = 3(4) - 23

y = -11.

A window is being replaced with tinted glass. The plan below shows the design of the window. Each unit length represents 1 foot.

Ilia_Sergeevich [38]

Let us solve for the total area. In this problem, we solve area 1 (the rectangle in the middle) and the area 2 ( the two half circle on the sides).

Solve for area 1:
Area rec = L * W = 5units * 4 units = 20 squared units

Solve for area 2:
Area cir = pi *r² = 3.14 * (2 units)² = 12.56 squared units

Total area = 20 + 12.56 = 32.56 foot²
Total cost = 32.56 foot² * ($23/foot²) = $ 748.88

Total cost is $748.88.

Part one: Sequence and Series

ASHA 777 [7]

Answer:

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

Here a = 13 and d = - 2.5, thus

$a_{29}$ = 13 + (28 × - 2.5) = 13 - 70 = - 57

Aaron is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. What would b

Ede4ka [16]

Let x represent number of wrong questions answered by Aaron.

We have been given that Aaron is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. We are asked to find Aaron's score (out of 20) if he got 6 questions wrong.

To find Aaron's score, we will subtract number of wrong answers from total score.

$\text{Aaron's score}=\text{Total score}-\text{Number of wrong answers}$

$\text{Aaron's score}=20-6$

$\text{Aaron's score}=14$

Therefore, Aaron's test scores would be 14 out of 20.

To find Aaron's score if he got x questions wrong, we will subtract x from total scores that is $20-x$ .

Therefore, Aaron's score would be $20-x$ , if he got x questions wrong.
