Step-by-step explanation:
[tex]a_{1} = -6\\\\a_{n}=\frac{1}{2}a_{n-1} - n\\\\a_{2}=\frac{1}{2}a_{1}-2\\\\ = \frac{1}{2}*(-6)-2\\\\ = -3 - 2\\\\= -5\\\\a_{3}=\frac{1}{2}a_{2}-3\\\\= \frac{1}{2}*(-5)-3\\\\=\frac{-5}{2}-3\\\\= \frac{-5}{2}-\frac{3*2}{1*2}\\\\=\frac{-5}{2}-\frac{6}{2}\\\\=\frac{-11}{2}[/tex]
If the points (2, 4), (5, k), and (8, 20) are on the same line, what is the value of k?
Answers
Answer:
k = 12
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (8, 20)
m = [tex]\frac{20-4}{8-2}[/tex] = [tex]\frac{16}{6}[/tex] = [tex]\frac{8}{3}[/tex]
Repeat using (5, k) as one of the points and equate to [tex]\frac{8}{3}[/tex]
(x₁, y₁ ) = (2, 4) and (x₂, y₂ ) = (5, k) , then
m = [tex]\frac{k-4}{5-2}[/tex] = [tex]\frac{k-4}{3}[/tex] = [tex]\frac{8}{3}[/tex] ( cross- multiply )
3(k - 4) = 24 ( divide both sides by 3 )
k - 4 = 8 ( add 4 to both sides )
k = 12

Answer:
1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.
2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

Find the sine, cosine, and tangent of angle A. (fraction as in simplest form please.)
Answers
Answer:
SinA=3/5
CosA=4/5
TanA=3/4
Step-by-step explanation:
first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2
20^2-16^2=144 the square root of 144 is 12 so side length bc=12
so sin is opposite/hypotenuse
the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5
cos is adjacent/hypotenuse
the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5
tan is the opposite/adjacent
the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answers
Answer:
x = -4, y = 9
or
(-4, 9)
Step-by-step explanation:
x - 5y = -49
y = -2x + 1
substitute y for -2x + 1
x - 5(-2x + 1) = -49
x + 10x - 5 = - 49
add 5 to both sides
x + 10x - 5 + 5 = - 49 + 5
x + 10x = -44
11x = -44
divide both sides by 11
11x/11 = -44/11
x = -4
substitute x for -4 in any of the original equations
y = -2x + 1
y = -2 * -4 + 1
y = 8 + 1
y = 9
Answer:
x = -4, y = 9 or (-4,9)
Step-by-step explanation:
.....
Solve each of the following system of equations by substitution!!!
x-5y=-49
y=-2x+1
Answers
Answer:
(-4,9)
Step-by-step explanation:
substitute the given value for y into the first equation
x-5(-2x+1)=-49
distribute
x+10x-5=-49
add like terms
11x-5=-49
add 5 to both sides
11x=-44
divide both sides by 11
x=-4
now plug x into into the second equation
y=-2(-4)+1
y=8+1
add like terms
y=9

o (3, 2)
Answers
Answer: (2,3)
====================================================
Explanation:
The intersection point of the two lines is where the solution point is located.
The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.
At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.
So that's how we get to (2,3)
