if p= -1, 5 Rx axis (P)
Answer:
P'(7, 5)
Step-by-step explanation:
Rule for the transformation of a point [tex]R_{x=1}(P)[/tex] defines,
Reflection of a point P(x, y) about a line, x = 1 which is parallel to y-axis.
Line x = 1 works like a mirror so the distance between the line and the image point will be equal to the distance between the line and the original point.
Distance between the line and a point (-1, 5) = 4
Therefore, distance between the line and the image point = 4
Coordinates of the image point will be,
P'(3, 5)

Step-by-step explanation:
We multiply both sides by 5.
If you were to use the “Completing the Square” method to solve the equation below for k, what number would you add to both sides of the equation? k 2- 8k = -4
A) 16
B) –16
C) 24
D) –24
Answer:
The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.
Step-by-step explanation:
To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

One number is 8 more than another, and their sum is 80. What is the smaller number?
34
36
38
40
========================================================
Work Shown:
x = smaller number
x+8 = larger number, since it's 8 more than the smaller value
Add up those two expressions, and set the sum equal to 80.
Then solve for x.
x+(x+8) = 80
2x+8 = 80
2x = 80-8 ... subtract 8 from both sides
2x = 72
x = 72/2 .... divide both sides by 2
x = 36
The smaller value is 36 while the larger value is x+8 = 36+8 = 44
Note how 36+44 = 80 to help verify the answer.
Answer:
34.
Step-by-step explanation:
80 = (34 + 8) + x
80 = 42 + x
38 = x
^^ that is an answer, but the question asks for the SMALLER number... Which is up at the beginning of my equation.
I hope this helps. I'm not entirely sure if it's correct, but it's worth a shot... lol
HELP ASAP!!! Identify the factored form of each polynomial
Answer:
9x2 +42x + 24 is (x + 4) (9x + 6)
9x2 + 30x + 24 is (3x + 6) (3x + 4)
9x2 + 58x + 24 is (9x + 4) (3x + 4)
I tried reversing it, instead of doing these - 9x2 + 58x + 24 I did (9x + 4) (3x + 4)

after locating the tenth, we follow rounding principles. if the number to the right is 0-4, the place value you are looking at stays the same (which happens in our case). If the number to the right is 5+, we round the number to the left up so if it was 12.27, it would be 12.3

12) There are two rectangular doors that are similar. The smaller door has a height of 3 ft. and a width of 2 ft. The bigger door has a width of 8 ft. What is the height of the bigger door? (Draw a picture, set up a proportion, and show all work.)(3pts)
Answer:
it's twelve you're welcome
Answer:
12 ft
Step-by-step explanation:
Since the doors are similar then the ratios of corresponding dimensions are equal.
let x be the height of the bigger door, then
[tex]\frac{small}{big}[/tex] : [tex]\frac{3}{x}[/tex] = [tex]\frac{2}{8}[/tex] ( cross- multiply )
2x = 24 ( divide both sides by 2 )
x = 12
Height of the bigger door is 12 ft

will give brainliest m^2= -7m + 6
Answer:
m =(-7-√73)/2=-7.772
Step-by-step explanation:
Answer:
m=−7/2+1/2√73 or m=−7/2+−1/2√73
Step-by-step explanation:
Let's solve your equation step-by-step.
m2=−7m+6
Step 1: Subtract -7m+6 from both sides.
m2−(−7m+6)=−7m+6−(−7m+6)
m2+7m−6=0
For this equation: a=1, b=7, c=-6
1m2+7m+−6=0
Step 2: Use quadratic formula with a=1, b=7, c=-6.
m=−b±√b2−4ac/2a
m=−(7)±√(7)2−4(1)(−6)/2(1)
m=−7±√73/2
m=−7/2+1/2√73 or m=−7/2+−1/2√73

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. Starting with 185 grams of a radioactive isotope, how much will be left after 3 half-lives?
Use the calculator provided and round your answer to the nearest gram.
Answer:
25 grams
Step-by-step explanation:
Three half live
1/2 * 1/2 * 1/2 = (1/2)³ = 1/8
