Write the standard equation of the circle with the given center that passes through the given point
Kitty [74]
Circle equation
(x - h)^2 + (y - k)^2 = r^2
Since radius isn't given use the center and point, with the distance formula, to find the radius.
D=sqrt((x2-x2)^2+)y2-y1)^2)
D=sqrt((1-0)^2+(2-6)^2
D=sqrt(1+16)
D=sqrt 17
radius = sqrt 17
(h, k) is the center and r is the radius
(x - 1)^2 + (y - 2)^2 = 17

Two sides of a triangle are 8cm and 12cm. Which of the following CANNOT be the measure of the third side,
blondinia [14]

Answer:

4 cannot be the measure of the third side. This is because of the Triangle Inequality Theorem, which states that the sum of two sides of a triangle must be greater than the third side (A+B>C, A+C>B, B+C>A) In this example, if side C were 4, side C (4) plus side A (8) would be 12. Since side B is 12, and 12 cannot be greater than 12, 4 would not work.

Answer=8

HELP PLZ <br> i need help with this math side i just need b,c,d a =4x+2y=16
tino4ka555 [31]

Answer:

Please check the explanatio.

Step-by-step explanation:

Solving Part b)

We know that the slope-intercept form of the equation line is

y=mx+b

where m is the slope and b is the y-intercept

Given the equation

4x+2y=16

Re-writing the equation in the slope-intercept form

4x+2y=16

y=-2x+8

Here, m=-2 and b=8

Thus, the equation in the slope-intercept form will be:

y=-2x+8

Solving Part c)

As you sold two pounds of cheddar cheese.

i.e. y=2

substituting y=2 in the slope-intercept form of the line equation

y=-2x+8

2=-2x+8

Subtract 8 from both sides

-2x+8-8=2-8

-2x=-6

Divide both sides by -2

\frac{-2x}{-2}=\frac{-6}{-2}

x=3

You sold 3 pounds of swiss cheese.

Solving Part d)

y=-2x+8

putting x=2.5 in the equation

y=-2x+8

2=-2\left(2.5\right)+8

2=3

The sides are not equal

<em>FALSE</em>

Thus, x=2.5 does not make any sense in the context of the problem.
