Answers

Answer 1

Answer:

x+y = 15

2x - y = 6

how could you correctly rewrite 4(5+3)=2(22-6) using the distributive property

Answers

The correct value in its simplified form 32 = 32

So that we can write this expression in its correct form - it's just multiplying the terms outside the parentheses - for the terms that are inside the symbol.

Resolution

4( 5 + 3 ) = 2( 22 - 6 )

4 · 5 + 4 · 3 = 2 · 22 - 2 · 6

20 + 12 = 44 - 12

32 = 32

Therefore, the correct simplified form of this question is 32 = 32. So, the equality is true.

A sinusoidal function whose period is 4π, maximum value is 6, and minimum value is -2 has
a y intercept of 6.
What is the equation of the function described?

Answers

The sinusoidal function described is f(x) = 4*cos(x/2) + 2.

What is the equation of the function described?

First, the amplitude is equal to half of the difference between the maximum and the minimum, so the amplitude is:

A = (6 - (-2))/2 = 4

The midline is equal to the minimum plus the amplitude:

M = -2 + 4 = 2.

now, we know that the y-intercept (when the function is evaluated in x = 0) is 6, so from that we conclude that we have a cosine function:

f(x) = 4*cos(kx) + 2

Notice that when evaluated in zero, we get:

f(0) = 4*cos(0) + 2 = 6.

Finally, we need to find the value of k.

Notice that the period of this function is 4π, while the period of the general cosine function is 2π, then we must have:

k*4π = 2π

Solving for k, we get:

h = (2π)/(4π) = 1/2.

Then the sinusoidal function described is f(x) = 4*cos(x/2) + 2.

Money in a bank triples every 10 years. If $100 is deposited today, what will its value be after 40 years? PLEASE SHOW ME STEP BY STEP AND I WILL GIVE YOU BRAINLIEST!!

a) $400 b) $1200 c) $6400 d) $8100 e) $24,300

Answers

Answer:

d) $8,100

Step-by-step explanation:

Given information:

Money triples every 10 yearsInitial deposit = $100Number of years invested = 40 years

If the money triples (multiplies by 3) every 10 years,
then in 40 years time it will triple 4 times, as 40 ÷ 10 = 4

⇒ Account balance after 40 years = $100 × 3 × 3 × 3 × 3

                                                         = $100 × 3⁴

                                                         = $8,100

Proof

In 10 years time the balance of the account will be:

$100 x 3 = $300

In another 10 years time, the balance of the account will be:

$300 x 3 = $900

In another 10 years time, the balance of the account will be:

$900 x 3 = $2700

In another 10 years time, the balance of the account will be:

$2700 x 3 = $8100

Which equation best models the data y=186-6.2x, y=246-6.2x, y=186-12.4x, y=246-12.4x which one

Answers

The equation that best models the data is (a) y = 186 - 6.2x

How to determine the equation?

The data is not provided; so I would give a general guide on how to model a linear equation.

Assume the points on the line are:

(0,186) and (1,179.8)

Start by calculating the slope of the line using:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

This gives

[tex]m = \frac{179.8 - 186}{1 - 0}[/tex]

Evaluate

m = -6.2

The equation is then calculated using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives

y = -6.2(x - 0) + 186

Evaluate

y = -6.2x + 186

Rewrite as:

y = 186 - 6.2x

Hence, the equation that best models the data is (a) y = 186 - 6.2x

The line given by -7x+8y = -16 is dilated by a scale factor of k = 3, centered at the origin. What is an equation of the image of the line after dilation?

Answers

We conclude that the image after the dilation is:

y =  -6 + (21/8)*x

How to write the dilation?

For a function y = f(x), a dilation of scale factor k is written as:

g(x) = k*f(x)

In this case, our function is given by:

-7x + 8y = -16

Solving for y we get:

y = (-16/8) + (7/8)*x

y = -2 + (7/8)*x

Now we apply a scale factor k = 3, so we get the dilated line:

y = 3*( -2 + (7/8)*x) = -6 + (21/8)*x

So we conclude that the image after the dilation is:

y =  -6 + (21/8)*x
