Answer:
Tell whether the following equations represent a linear function.
<em><u>10x + 2y = 4--linear </u></em><em><u>equation✓</u></em>
−x² + 3y = 19--quadratic equation
<em><u>6x + 1/2y = 3--linear </u></em><em><u>equation✓</u></em>
<span>We
need to rename the given number which is 780 000 into 78 ________.
=> But before we rename it, we need to find the value of 78
=> Since this is a 6 digit whole number, we have ones, tens, hundreds,
thousands, ten thousands, hundred thousands.
=> 7 = hundred thousands
=> 8 = ten thousands
=> 7 hundred thousands + 8 ten thousands
=> Thus, the renamed of 780 000 is 7 hundred 8 ten thousands.

Answer:
Outside the circle
Step-by-step explanation:
Let's first write the equation of this circle: 
, where (h, k) is the center and r is the radius. Here, the center is (-6, -2). We need to find the radius, which will just be the distance from N to E:
NE = 
The radius is √34, which means that r² = 34. So, our equation is:
(x + 6)² + (y + 2)² = 34
Plug in -10 for x and -7 for y:
(x + 6)² + (y + 2)² = 34
x² + 12x + 36 + y² + 4y + 4 = 34
x² + 12x + y² + 4y + 40 = 34
x² + 12x + y² + 4y + 6 = 0
(-10)² + 12 * (-10) + (-7)² + 4 * (-7) + 6 = 7
Since 7 > 0, we know that H lies outside the circle.
If Carly had more DVDs than Rob then you would subtract her amount away from the total. 42-4=38
Answer:
(4, 3)
Step-by-step explanation:
If this point is reflected about the x-axis, the x-coordinate does not change. The original y-coordiate, -3, becomes +3.
A': (4, 3)
