Which of the points plotted below satisfy the equation in the box? <br><br>Check all that apply.

coldgirl [10]

Im not 100% sure but, this is how I solved the problem. Just plug the coordinates into the equation. For example, (3,9) x=3 and y=9.
the equation is y=x*3 so 9=3*3 and 3*3=9 so that point is true. If you continue to do the same thing for all the point you should get F,C, and D

Answer:

$P = 58$

Step-by-step explanation:

<em>The image if the circle and triangle can be found online</em>

Given

$JA = 8$

$AL = 8$

$CK = 10$

Required

The perimeter of JKL

Since the mid-points of the tangents are A, B and C respectively.

$JK = JB + BK$

Where

$JB = JA = 8$

$BK = CK = 10$

So:

$JK =8+10 =18$

$JL = JA + AL$

$JL = 8+11 = 19$

$KL = CL + CK$

Where

$CL =AL = 11$

So:

$KL = 11+10 = 21$

So, the perimeter (P) is:

$P = JK+ KL +JL$

$P = 18 + 19 + 21$

$P = 58$

Answer:

(86.2,0) is the x-intercept.

Step-by-step explanation:

You can use the slope formula to figure this one out:

Just use two of the points on the table, any of them will work:

$(33,-22)\\(52,-33)$

$\frac{-22-33}{33-52} =\frac{-55}{-19}=\frac{55}{19}$

Now you have the slope of the equation, now using the y-intercept equation you can substitute the variables for point of the table and the new slope.:

$(71,-44)\\y=mx+b\\-44=\frac{55}{19} (71)+b$

Now just solve for b to get the y intercept:

$-44=\frac{55}{19}(71)+b\\-44= \frac{3905}{19} +b\\(-\frac{3905}{19})-44=\frac{3905}{19} +b(-\frac{3905}{19})\\ -\frac{4741}{19}=b$

Now you have the y-intercept so you just have to plug in 0 to the y spot and it will calculate the x-intercept.

$0=\frac{55}{19}x-\frac{4741}{19}\\(+\frac{4741}{19})0=\frac{55}{19}x-\frac{4741}{19}(+\frac{4741}{19})\\\\\frac{4741}{19}=\frac{55}{19}x\\\frac{\frac{4741}{19}}{\frac{55}{19} }= \frac{\frac{55}{19} x}{\frac{55}{19} } \\\frac{431}{5} =x\\or\\86.2=x$

And that's the x-intercept.
