Answer:

Smaller number = 4

Larger number = 13

Step-by-step explanation:

Smaller number = x

Larger number = 4x - 3

Sum of the numbers = 17

x + 4x -3 =  17   {Combine like terms}

   5x - 3 = 17    {add 3 to boht sides}

        5x = 17 + 3

        5x = 20      {Divide both sides by 5}

          x = 20/5

         x = 4

      Larger number = 4x - 3

                               = 4*4 -3

                                = 16 - 3

                                = 13

We know that in order to solve a math problem, we need an equation. Luckily there's an equation to find the slope and intercept of a (straight) line!

Because of the equation:

Y = mx + b

You can use it to find the Y intercept, and then therefore slope (or the other way around)!

First, look at the point where the line meets with the y axis.

It's not clear, but it's 7.

That's your 'Y intercept'. Easy!

Then, to find the slope. There are a couple of ways to find it, but I'll show you the one using the y = mx + b equation.

In the equation, 'b' represents the Y intercept. Since we already know our Y intercept on the graph is 7, we can plug that into the equation.

Y = mx + 7

What's m? M is the slope of the line. In order to find this, we need more numbers to work with. Numbers from the line's coordinate points.

Since coordinates in a graph have x and y, we can plug in any coordinate from the graph's line into our equation (y = mx +7).

I choose...this point (points at random coordinate on line).

(3, 10) aka (x, y)

It's on the line, right? So it will be a reliable x and y.

Put the numbers in...

10 = 3m + 7

This looks a bit easier, right? Now we solve for m (the slope)!

Combine like terms.

10 - 7 = 3m

Divide the 3.

3/3 = m

m = 1.

That's your slope!

So, taking the solution, we can determine that the slope of the line is 1, and the intercept of the line is 7.

Y = x + 7

Hope it helps! This is the most I can do for you :)

Write out the steps that you would follow to solve the equation: 3(x-4) = 2x +5
luda_lava [24]

Answer:

x = 17

Step-by-step explanation:

To solve this equation, we can illustrate the algebraic concepts being employed and solve for the variable.

3(x - 4) = 2x + 5 Distribute the 3 into the parentheses.

3x - 12 = 2x + 5 Subtract 2x from both sides of the equation to combine like terms.

x - 12 = 5 Add 12 to both sides of the equation.

x = 17
