Answer:
Just from point a go 8 spaces to the left and place the dot over there.
Step-by-step explanation:
Since you are getting a reflection of a you need to move 4 spaces to the left of the line to get an exact mirror of point a or relfelction.
To plot the reflected point of A under a reflection across line l, just move 8 units across the line "l" horizontally.
The reflected point of A should be written as A'.

Help.. Suppose Q is the midpoint of PR
Answers
Answer:
[tex]3x+41[/tex] or 38
Step-by-step explanation:
If Q is the midpoint of Line PR, then lines PQ and QR add up to equal Line PR. We then get
[tex]PQ=6x+25\\QR=16-3x\\PQ+QR=PR\\6x+25+16-3x=PR\\3x+41=PR\\[/tex]
If you want to know the exact number that PR is, we can do additional steps where PQ = QR.
[tex]PQ=6x+25\\QR=16-3x\\PQ=QR\\6x+25=16-3x\\9x+25=16\\9x=-9\\x=-1\\\\3x+41=PR\\3(-1)+41=PR\\-3+41=PR\\38=PR\\PR=38[/tex]
Find the 14th term of the geometric sequence 5, -10, 20, ...5,−10,20,
Answers
Answer:
40,960
Step-by-step explanation:
To find the multiplier, set up an equation like this:
[tex]5x=-10[/tex]
The above equation will allow us to find what number, when multiplied with 5 will result in -10. If we divide both sides of the equation by 5, we'll find that the number, x, is -2:
[tex]x=-2[/tex]
We need to find the 14th term. To do this, simply multiply the lattermost number in the sequence by our multiplier, -2.
[tex]20*(-2)=40[/tex]
Since 5 is the first term in the sequence, -10 is the second term in the sequence, and 20 is the third term in the sequence, 40 is the fourth term. Now we just need to find the next ten so that we can find the 14th term. To do that, repeat the process of multiplying the lattermost number by -2 ten more times:
[tex]40*-2=-80\\-80*-2=160\\160*-2=-320\\-320*-2=640\\640*-2=-1280\\-1280*-2=2560\\2560*-2=-5120\\-5120*-2=10240\\10240*-2=-20480\\-20480*-2=40960[/tex]
Therefore, the 14th term is 40,960.

X/3 - X/6 = 2
What is the value of x how do I do it?
Answers
Answer:
Value of X is 18
Step-by-step explanation:
x/3 - x/6 = 2
multiply first fraction by 3 so u get X by its self then multiply the 2 by 3
x - x/6 = 6
then multiply the fraction by 6 to get X by itself then multiply the 6 by 6 because what u do to one side u have to do to the other
2x/2 = 36/2
x= 18

1+sinx+cosx/1+sinx-cosx=1+cosx/sinx help pls by proving
Answers
Answer:
Below.
Step-by-step explanation:
I'll write sin x as s and cos x as c so we have:
(1 + s +c)/(1 + s - c) = (1 + c)/s
Cross multiplying:
s + s^2 + cs = 1 + s - c + c + cs - c^2
s + s^2 + cs = 1 + s + cs - c^2
s^2 + c^2 + s - s + cs - cs = 1
s^2 + c^2 = 1.
- that is sin^2 x + cos^2 x = 1 which is a known identity.
Therefore the original identity is proved.

x=31
Answer:
x = 31
Step-by-step explanation:
- Combine all like terms;
8+2x-12=58
2x -4 = 58
- Add 4 to both sides.
2x = 62
- Divide both sides by 2.
x = 31

Simplify the radical

Answers
Answer:
Step-by-step explanation:
54 = 6*9
That means there are 3 threes and 1 two
54 = 2*3 * 3 * 3
There are a pair of 3s and a two and a 3 left over.
The two and the three remain under the root sigh.
One of the pair of threes comes out of the root sign.
The other one is thrown away.

Question 2
Label the length of each side in inches
Answers
Answer:
1) s=15
2) 15, 21, 21, 15, 30 from left to right
Step-by-step explanation:
First you turn this into an equation: s+6+s+6+s+s+2s
Collect like terms: 4s+ 12 + 2s
Simplify: 6s+12
Bring back into a full equation: 6s+12=102
Simplify= 102-12=6s
90= 6s
90/6=s
s=15
Then bring back into sides: Left side and right sides are 15 as s= 15
15+6= 21 so both top sides are 21
2×15=30
So it goes in the order from left to bottom clockwise:
15, 21, 21, 15, 30

Answers
Answer:
(0,-1) I could be wrong
Step-by-step explanation:
Answer:
Step-by-step explanation:
-2x+9y=-9 (solve for x)
-2x= -9y-9
X = - 9y/-2 - - 9/2. X = 9y/2 + 9/2
9(9/2y+9/2)-2y=2
81y/2 + 81/2 - 2y = 2
81y/2 - 2y = 2 - 81/2. 81/2 - 2 = 77/2 and -81/2 +2 = -77/2
77/2 y = - 77/2
y = (-77/2)/(77/2)
y = - 1
