7 0

Answer:

Charles = 18

Barbara = 3

Step-by-step explanation:

<em>Currently</em>

Charles: x+15

Barbara: x

<em>In twelve years</em>

Charles: x+27

Barbara: x+12

<em>Equation </em>- Charles's age in twelve years will be double Barbara's age in twelve years. Using the information about, create the equation

x+27=2(x+12)

x+27=2x+24

x=3

Answer:

<em>Option C</em>

Step-by-step explanation:

Consider each of these graphs. Let us formulate an inequality for each of them, and match the one with an inequality of x > - 14.5;

Graph 1, x > 13.5\\Graph 2, x \geq 14\\Graph 3, x > 14.5\\Graph 4, x \geq 15

Graph 3 is the only one that matches with the inequality provided to us.

* Note that shaded circles are represented by a greater / less than or equal to, and non - shaded circles are represented by a greater / less than sign.

<em>Solution ⇒ Graph 3</em>

C is the point on the line y = 2x + 1 where x = 2<br> Find the co-ordinates of the mid-point of BC.
inysia [295]

Based on the calculations, the coordinates of the mid-point of BC are (1, 4).

<h3>How to determine coordinates of the mid-point of BC?</h3>

First of all, we would determine the initial y-coordinate by substituting the value of x into the equation of line that is given:

At the origin x₁ = 0, we have:

y = 2x + 1

y₁ = 2(0) + 1

y₁ = 2 + 1

y₁ = 3.

When x₂ = 2, we have:

y = 2x + 1

y₂ = 2(2) + 1

y₂ = 4 + 1

y₂ = 5.

In order to determine the midpoint of a line segment with two (2) coordinates or endpoints, we would add each point together and divide by two (2).

Midpoint on x-coordinate is given by:

Midpoint = (x₁ + x₂)/2

Midpoint = (0 + 2)/2

Midpoint = 2/2

Midpoint = 1.

Midpoint on y-coordinate is given by:

Midpoint = (y₁ + y₂)/2

Midpoint = (3 + 5)/2

Midpoint = 8/2

Midpoint = 4.

Therefore, the coordinates of the mid-point of BC are (1, 4).
