Hey there! :)

Answer:

D : [-4, ∞)

R: [-2, ∞)

Step-by-step explanation:

Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:

[ is used for closed points.

( is used for arrows or open circles.

Therefore:

This graph goes from x = -4 towards x ⇒∞. Therefore:

D : [-4, ∞)

The range of this function goes from x = -2 towards y⇒ ∞. Therefore:

R: [-2, ∞)

The sum of the squares of their ages is; 5x²

<h3>How to Solve Algebraic Word Problems?</h3>

We are told that Maria is twice the age of Miriam.

Now, of the age of Miriam is x, then we can say that;

Age of Mariam = x

Age of Maria = 2x

Now, we want to find the sum of the squares of their ages. Thus, this is expressed as;

x² + (2x)²

= x² + 4x²

= 5x²

Write the equation of the line that passes through the points (6,2) (4,1)

Alisiya [41]

Answer: y=1/2x-1

Step-by-step explanation:

To find the equation of the line that passes through the points, we need to find out slope, m.

$m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$

We plug our points into this formula to find slope.

$m=\frac{1-2}{4-6} =\frac{-1}{-2} =\frac{1}{2}$

Our slope is 1/2. To find our y-intercept, b, we would plug any point into the equation for slope-intercept form.

y=mx+b

y=1/2x+b

1=1/2(4)+b

1=2+b

b=-1

Now that we know b, our equation is y=1/2x-1.
