Answer:

(x + 7)2 + (y + 1)2 = r2.

To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.

So, equation of circle: (x + 7)2 + (y + 1)2 = 289

#1) What is the measure of ∠TVU, and why?

mrs_skeptik [129]

1) Answer: A

because trangles RST is similar to VUT as:

<RST=<VUT=55 (Angle)

<RTS=<VTU=90 (it seems right angled) Angle

So by AA similarity...(two angles similarity is enough)

2) Answer:B

y+z=x because exterior angle of a triangle (which is x) must be equal to sum of non-adjacent (y and z) interior angles.

3) Answer: A should be right choice. Step 1 is wrong here which is,

m<m + m<n + m<p=180 (wrong)

It should be:

m<m + m<n + m<0=180 (right)

The equation of a line is y = 17x -6

julia-pushkina [17]

Answer:

Step-by-step explanation:

the point where the line crosses the y-axis has its x value = 0.

hence y = 17 * 0 -6 = -6

so (0, -6)

What is 5 3/4 times 2/6? I am doing math homework and need help

Jobisdone [24]

53/4•2/6=1 11/12
Because you must turn 5 3/4 into an improper fraction. So 23/4•2/6. Next you are able to cross reduce because 2 goes into 2 and four so now you have 23/2•1/6 now just multiply across. 2•6=12 and 23•1=23 so now you have 23/12 which equals
1 11/12

Combine the following fractions. <br><br> a. 3/5 + 4/15 <br><br><br> b. 5/6 - 1/4

Ne4ueva [31]

Hello there! :)

Answer:

1. $\boxed{\frac{13}{15} }$

2. $\boxed{\frac{7}{12} }$

Step-by-step explanation:

1. 3/5+4/15

First, you multiply by numerator and denominator.

3*3=9

5*3=15

$=\frac{9}{15}$

Then, you had to combine by the fractions.

$\frac{9}{15}+\frac{4}{15}$

Add by the numbers from left to right.

9+4=13

<u><em>13/15 is the final answer.</em></u>

______________________________________________

2. 5/6-1/4

First, you multiply by 2 both sides of numerator and denominator.

5*2=10

6*2=12

10/12

3/12

$\frac{10}{12}-\frac{3}{12}$

Subtract by the numerator.

10-3=7

<em><u>7/12 is the final answer.</u></em>

Hope this helps!

Thanks!

Have a nice day! :)
