Answer:

x = 15

Step-by-step explanation:

Simplifying

3x + (8x + 15) = 180

Reorder the terms:

3x + (15 + 8x) = 180

Remove parenthesis around (15 + 8x)

3x + 15 + 8x = 180

Reorder the terms:

15 + 3x + 8x = 180

Combine like terms: 3x + 8x = 11x

15 + 11x = 180

Solving

15 + 11x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 11x = 180 + -15

Combine like terms: 15 + -15 = 0

0 + 11x = 180 + -15

11x = 180 + -15

Combine like terms: 180 + -15 = 165

11x = 165

Divide each side by '11'.

x = 15

Simplifying

x = 15

Math 8: Linear Functions, Part 2
Studentka2010 [4]

Answer:

\boxed{\text{1. y + 5 = -4(x - 3); \qquad 2. y - 8 = x + 1}}

Step-by-step explanation:

Question 1

The point-slope formula for a straight line is

y – y₁ = m(x – x₁)

x₁ = 3; y₁ = -5; m = -4  

Substitute the values

\boxed{\textbf{y + 5 = -4(x - 3)}}

The diagram shows the graph of equation 1 (red) with slope -4 passing through (3,-5).

Question 2

x₁ = -1; y₁ = 8; m = 1  

Substitute the values

\boxed{\textbf{y - 8 = x + 1}}

The diagram shows the graph of equation 2 (green) with slope 1 passing through (-1,8).

There are two twins. One twin wants to explore the planet near Proxima Centauri and leaves on a spaceship traveling at 90% of th
miskamm [114]

Answer:

<em>4.7 years</em>

Step-by-step explanation:

Distance of planet from Earth = 1.3 parsec

We know that 1 parsec = 3.26 light years

And a light year is the distance traveled by light in time period of 1 year.

So, Distance of planet from Earth = 1.3 \times 3.26 = 4.24 light years

Given that, the person travels at a speed equal to 90% of the light speed.

To travel to the planet from Earth, Light takes 4.24 years.

To travel the distance D, at a speed s light takes time of 4.24 years.

To travel the distance D, at a speed 0.90s, the person takes time:

\dfrac{4.24}{0.90} = \bold{4.7\ years}

So, the twin on Earth ages by <em>4.7 years.</em>
