Answer:
a) d = 3 b) a(n) = 3n – 13 c) a(27) = 68
Step-by-step explanation:
solutions are (x, y) = (29,13) and (9349, 4181), which lead to (a, b) = (15,5) and (4895 ... corresponding to integer values of x give the quadruples. (x, y, z ... Since no number congruent to 3, modulo 4, can be written as the sum of two squares ... k is odd, the equation x2 - (k2 - 4)y2 = 4 has smallest solution in positive integers .
which is the area of the circle if AB=4
One number is nine more than a second number. Four times the first is 6 less than 2 times the second. Find the numbers.
9514 1404 393
Answer:
-12, -21
Step-by-step explanation:
Let x represent the first number. Then the second is x-9. The other relation is ...
4x = 2(x-9) -6
2x = -24 . . . . . subtract 2x, simplify
x = -12
x-9 = -21
The first number is -12; the second number is -21.

can somebody help me, major grade and is timed, pre ap geometry
Step-by-step explanation:
First find the value of Y=> 5y-8=3y+1
=> 5y-3y=1+8
=> 2y=9
=> y=4.5
Second find the value of X=> x+6=4x
=> 6=4x-x
=> 6=3x
=> x=(6/3)
=> x=2
Thus, x=2 and y=4.5 [Option C]

Pls hurry and help!!!!3x-2y=4
6x-2y =-2 solve the equations by using elimination show work
I hope my steps are clear to uh
Answer:
x=−2 and y=−5
Step-by-step explanation:
Solve3x−2y=4for x:
3x−2y=4
3x−2y+2y=4+2y(Add 2y to both sides)
3x=2y+4
3x /3 = 2y+4 /3 (Divide both sides by 3)
x= 2 /3 y+ 4 /3
Substitute 2 /3 y+ 4 /3 for x in6x−2y=−2:
6x−2y=−2
6( 2 /3 y+ 4 /3 )−2y=−2
2y+8=−2(Simplify both sides of the equation)
2y+8+−8=−2+−8(Add -8 to both sides)
2y=−10
2y /2 = −10 /2 (Divide both sides by 2)
y=−5
Substitute−5 for y in x=
2 /3 y+ 4 /3 :
x= 2 /3 y+ 4 /3
x= 2 /3 (−5)+ 4 /3
x=−2(Simplify both sides of the equation)

P-21=34 P=34-21 P=13
What is the value of p?
Simplifying
P + -21 + -21 = 34 + -21
-21 + -21 + P = 34 + -21
Combine like terms: -21 + -21 = -42
-42 + P = 34 + -21
Combine like terms: 34 + -21 = 13
-42 + P = 13
Solving
-42 + P = 13
Solving for variable 'P'.
Move all terms containing P to the left, all other terms to the right.
Add '42' to each side of the equation.
-42 + 42 + P = 13 + 42
Combine like terms: -42 + 42 = 0
0 + P = 13 + 42
P = 13 + 42
Combine like terms: 13 + 42 = 55
P = 55
Simplifying
P = 55

Write the equation of the line, in slope intercept form, through the following two points.
Answer:
y=[tex]\frac{5}{8}x[/tex]
Step-by-step explanation:
So in this equation you have to do this with the points to get the slope
M= [tex]\frac{y2-y1}{x2-x1}[/tex]
M is the slope so using this eqaution will give you the equation.
I'm fishing. The probability of catching a fish on each cast of my rod (each attempt) is 0.23. Each attempt is independent. If I made 12 attempts and wanted to find the probability that I caught 2 or fewer fish, is this a geometric or binomial situation
Answer:
This is a binomial situation.
Step-by-step explanation:
For each attempt, there are only two possible outcomes. Either you catch a fish, or you do not. This can mean that either we have a binomial distribution, or a geometric.
However, each attempt is independent, which means that in each attempt, the probability of catching a fish is the same, and that this is a binomial situation.
The probability of catching a fish on each cast of my rod is a binomial distribution.
From the question, we can see that there are two possibilities which are whether you catch a fish or not. This gives two possibilities showing that we have a binomial distribution.
However, each attempt is independent, which means that one attempt does not affect the other. This is therefore a binomial situation.
Hence the probability of catching a fish on each cast of my rod is a binomial distribution.

Help please!!! Find x and Y
Answer:
x = 40
y = 15
Step-by-step explanation:
Given is an equilateral triangle.
Measure of each angle of an equilateral triangle is 60°.
Therefore,
(x + 20)° = 60°
x + 20 = 60
x = 60 - 20
x = 40
4y = 60
y = 60/4
y = 15

Answer:
QS = 16
Step-by-step explanation:
We can find QS by using the Pythagorean Theorem for Δ SQT
ST = 24/2 or 12
QT = 20
QS² + 12² = 20²
QS² + 124 = 400
QS² = 256
QS = √256, which is 16
