Answer:

All real numbers

Step-by-step explanation:

$-2(y - 4) = 20 - 2y - 12$

Start by distributing -2 inside the parentheses.

$-2y + 8 = 20 - 2y - 12$

Combine like terms on the right side of the equation.

$-2y + 8 = 8 - 2y$

Subtract 8 from both sides of the equation.

$-2y =- 2y$

Divide both sides by -2 to isolate y.

$0=0$

This is a true statement, so there are infinite solutions.

Arrange the slope values in order from least steep to most steep

polet [3.4K]

Answer:

0 => -⅘ => 1.5 => 3 => -4 => $-\frac{11}{2} (-5.5)$

Step-by-step explanation:

The greater the absolute value of a slope, the steeper the slope. By absolute value, we mean the non-negative value of tthe .

To arrange the slope values, from the least steep to the steepest, ignore the negative sign in any of the slope values.

Thus, in the order from the least steep to the steepest, we have:

0 => -⅘ => 1.5 => 3 => -4 => $-\frac{11}{2} (-5.5)$

The greater the absolute value of the slope, the greater the vertical movement. The greater the vertical movement, the steeper the slope.

A slope value of 0 connotes a horizontal line.

The endpoints of the longest chord on a circle are (4, 5.5) and (4, 10.5).the center of the circle is at the point , and its rad

Furkat [3]

The midpoint of the points ( 4, 5.5 ) and ( 4, 10.5 ) is the center of the circle:
C = $(\frac{4+4}{2}, \frac{5.5+10.5}{2})$
C = ( 4, 8 ), h=4, k=8
r = $\sqrt{(4-4)^{2} +(8-5.5)^{2} } = \sqrt{0+2.5^{2} }$
r = 2.5
The equation of the circle in standard form:
( x - h )² + ( y - k )² = r²
( x - 4 )² + ( y - 8 ) = 6.25

Answer: A (I think)

Step-by-step explanation: it would be left of 9 since it’s 8.77496438739

81 square rooted is 9 so 77 square rooted is less than 81 square rooted

And a number line counts up the more you go right.
