What fraction has a value that's equal to 3/4
Answers
Answer:
To calculate the slope (m) between two points (x₁, y₁) and (x₂, y₂), you can use the formula:
\[ m = \frac{y₂ - y₁}{x₂ - x₁} \]
For the points (2,1) and (-3,4):
\[ m = \frac{4 - 1}{-3 - 2} = \frac{3}{-5} \]
Simplifying the fraction, the slope is:
\[ m = -\frac{3}{5} \]

Greetings!
In this question, we need to solve the equation where "k" will be our subject variable.
We were given the equation: 10n = 5(k - 3)
In order for "k" to be the subject, we need to solve for "k" where "k" is by itself.
Solve the equation for k:
10n = 5(k - 3)
Use the distributive property to distribute the 5
10n = 5k - 15
Add 15 to both sides to get 5k by itself
10n + 15 = 5k
Divide both sides by 5 to get "k" by itself
2n + 3 = k
Therefore, when "k" is the subject the equation is rearranged to: k = 2n + 3
Answer:
k = 2n + 3
Find a possible formula for P(x)
Answers
remember the roots of a polynomial is
P(x)=(x-r1)(x-r2)...(x-rn)
so we have 5th degreee, means all exponents shoud add to 5
leading coeficient of 1, that means
P(x)=1x^n+bx^(n-1)...zx^0
means highest power coefience it 1
roots of multiplicity 2 at x=2 and x=0, means those roots show up 2 times each
root at x=2 means (x-2), it has multiplicity 2 so (x-2)^2
root at x=0 means (x-0), it has multiplicyt 2 so (x-0)^2
last one, multiplicity 1 and root at x=-4
(x-(-4))^1=(x+4)
so the polynomial is
2x – y = –2
x + 2y = 24
x – 2y = –16
Answers
Answer A
y-10=(11-10)/(6-4) * (x-4)
==>2y=x+16
