Answer:

C. AB=CD not necessarily true

Step-by-step explanation:

AD = DB True because the width of the compass was the same and hence the radius was same for both centers A and B

B. AE=EB True

CD makes the perpendicular bisectors if arcs are made with compass of same width

C. AB=CD . There is no property which says that it is necessarily true

D. AC=CB True because the width of the compass was the same and hence the radius was same for both centers A and B

The list of equations is shown in the picture which equation has No Solution, One Solution, and Infinitely Many Solutions.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have given a linear equation in one variable.

$\rm \dfrac{1}{2}y + 3.2y = 20$

After solving:

y = 5.40 (one solution)

$\rm \dfrac{15}{2}+ 2z -\dfrac{1}{4}=4z+\dfrac{29}{4} -2z$

After solving:

$\rm \dfrac{15}{2} -\dfrac{1}{4}=\dfrac{29}{4}$

$\rm \dfrac{29}{4}=\dfrac{29}{4}$ (Infinitely Many Solutions)

3z + 2.5 = 3.2 + 3z

2.5 = 3.2 (no solution)

Similarly, we can identify which equation has No Solution, One Solution, and Infinitely Many Solutions.

Thus, the list of equations is shown in the picture which equation has No Solution, One Solution, and Infinitely Many Solutions.

What equation is the equation of the line that passes through (-10,8) and (5,5)

Fofino [41]

The equation of the line is given by

y = mx + c

where m is the gradient of the line
c is where the line cuts the y-axis
x & y represent coordinates on the line.

The gradient m can be obtained as follows:

m = (5 - 8) / (5 - - 10) = (-3) / (15) = - 1/5

To obtain c, we use any known coordinate on the line and substitute it as well as the gradient in the general equation for the line.

Taking coordinates (5,5)

5 = (- 1/5)(5) + c

5 = - 1 + c

c = 6

Hence, the equation for this line is

y = -x/5 + 6
