5 0

Answer:

C. Inconsistent; none

Step-by-step explanation:

<u>Given system:</u>

2x + y = 7 ⇒ y = -2x + 7
y + 5 = -2x ⇒ y = -2x - 5

<u>We observe that:</u>

The slopes are same m = -2
The y-intercepts are different, b = 7 and b = - 5
The lines are parallel, so no solution

Correct choice is C

4. Which of the following indicates the multiplication property of equality when solving Vz= 5?

tiny-mole [99]

Answer:

D. 21.

Step-by-step explanation:

The general form of the equation of a circle is:

(x - a)^2 + (y - b)^2 = r^2 where r is the radius.

Comparing:

(x + 5)^2 + (y + 7)^2 = 21^2

So r^2 = 21^2

making r = √21^2

= 21.

These two lines are congruent (the same) so we can set them equal to each other and solve.

5x-4=3x+6

The first thing we need to do is subtract 3x from both sides leaving us with 2x-4=6

Now we can add 4 to both sides leaving us with 2x=2

Now we need to divide both sides by 2 to get x alone.

Giving us our final answer of x=1
