Answer:

is a way to express the definition of a circle on the coordinate plane.

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. Then complete the square for the y terms.

Is y = 0.5x - 1 a liner function

Mama L [17]

$\text{Yes, it is a linear function}\\\\\text{The reason why it's a linear function is because there is a constant change}\\\\\text{The constant change would be your slope, and the slope in this case}\\\text{is 0.5}\\\\\text{If you plug this equation in a graph, it would be a straight line forever}\\\\\text{If you want to know if a line is linear, just check the slope to see if it's}\\\text{constant.}$

matrenka [14]

Answer: x=10 7/8

Step-by-step explanation:

Subtract 3/4 from both sides. Multiply both sides by 3. Divide both sides by 2 (basically just isolate x on one side of the equal sign).

HACTEHA [7]

Step 1. <span>Distribute

</span> $3*12+3*-3 y^{2}$
<span>
Step 2. Simplify </span> $3*12$ to $36$

$36+3*-3 y^{2}$

Step 3. Simplify $3*-3 y^{2}$ to $-9 y^{2}$

$36-9 y^{2}$

Done! :)

Write the equation of the line that passes through (−1, 5) and has a slope of 3 in point-slope form. (2 points)

aleksandr82 [10.1K]

The point-slope form: $y-y_0=m(x-x_0)$

m = 3; (-1; 5) $\to x_0=-1;\ y_0=5$

subtitute

y - 5 = 3(x - (-1))

y - 5 = 3(x + 1)
