2(6x + 9 - 3x) - 5x + 21 how many solutions are there​
sergey [27]

Answer:

Only one solution.

Step-by-step explanation:

1) Collect like terms.

2((6x-3x)+9)-5x+21

2) Simplify (6x-3x)+9 to  3x+9.

2(3x+9)-5x+21

3) Expand by distributing terms.

6x+18-5x+21

4) Collect like terms.

(6x-5x) +(18+21)

5) Simplify.

x+39

Therefore, the answer is x + 39 and there is only one solution possible.

How does changing the function from f(x) = −5 cos 2x to g(x) = −5 cos 2x − 3 affect the range of the function?
Alla [95]
The graph has been moved 3 units downward, making the range change. The range of f(x) is [-5,5], while the range of g(x) is [-8,2]. The picture is of both functions. f(x) is blue, g(x) is red.

Answer:

Option (C)

Step-by-step explanation:

From the picture attached,

Two lines 'h' and 'k' are the parallel lines and a transversal 'n' is intersecting these parallel lines at two distinct points.

By the theorem of alternate interior angles, angle 8 and angle 11 will be equal in measure.

∠8 ≅ ∠11 [Alternate interior angles]

m(∠8) = m(∠11) = 118°

Therefore, Option (C) will be the answer.

5. Use the equation shown to answer a-b.
soldi70 [24.7K]

Answer:

a. No

b. 2.25 days

Step-by-step explanation:

0.75x + 3 = 0.25x + 5.25

a......................

Constants are $3 and $5.25 respectively

Topping costs $0.75 and $0.25 respectively

To have same cost the toppings number would be different as cost is different.

Suppose the number of toppings is x in one shop and y in the other, then the spending if same, we get this equation:

  • 0.75x + 3 = 0.25y + 5.25

The answer is NO due to two different variables in the equation

b.......................

Constants are $3 and $5.25 respectively

Joseph adds $0.75 each day and Kelsey spends $0.25 each day

Number of days should be same in this case, so variable will be same and the result (amount left in bank) is same.

<u>So the equation for this case is:</u>

  • 3 + 0.75x = 5.25 - 025x

<u>Solving, we get:</u>

  • 0.75x + 0.25x = 5.25 - 3
  • x = 2.25

This is the solution to equation despite being a whole number.
