Answer:

Is a consistent independent system

Step-by-step explanation:

we know that

If a system has at least one solution, it is said to be consistent .

If a consistent system has exactly one solution, it is independent .

If a consistent system has an infinite number of solutions, it is dependent

If a system not have solution, it is said to be inconsistent

In this problem we have

----> equation A

----> equation B

Solve the system by graphing

The solution is the intersection point both graphs

The solution is the point (7.5,-20.5)

see the attached figure

therefore

Is a consistent independent system

Find the measure of the arc or angle indicated. Part 1. NO LINKS.​
andreev551 [17]

Answer:

Step-by-step explanation:

1)

O = center of circle (origin)

we know that the angle at the center of the circle ∠ ROS will be

180= 2(31) + ∠x

180-62 = ∠x

118° = ∠x

The supplemental angle to the 118° will be 62°

62° is the interior angle to  arc QR , so

arc QR is also 62°

3)

b/c the intercepted arc YZ = 2* 68=136

then 136+125+? = 360

? = 99°

arc ZX = 99°

5)

O= center point

we are given the two arcs  120 and 70 for both of these we know that the

interior angles will be the same.  ∠JOX  has a central angle of 120 , then

b/c triangle JOX is an isosceles,  we know that the two angles J and X of

the triangle JOX will be 1/2 of  60 , or 30 each

also for    

also ∠XOY has an interior angle of 70 so the two angle at X and Y will be 1/2 of 110 , or 55°

now add 55+30 to find X for box XYZJ

85° = ∠X

Natalie paid $20.7 for 3 small pizzas and a salad which was $3.
expeople1 [14]

Answer:

Step-by-step explanation:

a) Let the cost of a Pizza = $ x

Cost of three pizza's = 3 *x = 3x

cost of 3 pizza + cost of a salad = $ 20.7

3x + 3 = 20.7

b) 3x + 3 = 20. 7     {Subtract 3 from both sides}

3x       = 20.7 - 3

     3x = 17.7  {Divide both sides by 3}

       x = 17.7/3

      x  = 5.9

Cost of one pizza = $ 5.9

Supplementary angles add to?<br><br>Advanced: Write an equation and solve for x in the diagram
Ray Of Light [21]

Supplementary angles add up to 180 degrees.

7x + 3x = 180 degrees.

Combine like terms.

10x = 180 degrees.

Divide both sides by 10

x = 18
