Answer: y-2 > 1/4(x-4)

Step-by-step explanation:

use slope formula y2-y1/x2-x1 so 2-0/4-(-4) = 1/4

slope int form is y-y1 = m(x-x1)

plug in one point

y-2 = 1/4(x-4)

insert (0,0)

you find y-2 > 1/4(x-4)

I need help finding the answer to this question on edge.

Answer:

Step-by-step explanation:

We need to evaluate :-

$\rm\implies \displaystyle\rm\sum^4_n (-1)^n (3n + 2 )$

Here the $\Sigma$ is the sum operator . And here we need to find the sum from n = 1 to n = 4 . We can write it as ,

$\rm\implies (-1)^1 ( 3*1 +2) + (-1)^2 ( 3*2+2) + (-1)^3(3*3+2) + (-1)^4(3*4+2)$

Now we know that for odd powers of -1 , we get -1 and for even powers we get 1 . Therefore ,

$\rm\implies -1 ( 3 + 2 ) + 1 (6+2)+-1(9+2)+1(12+2)$

Now add the terms inside the brackets and then multiply it with the number outside the bracket . We will get ,

$\rm\implies -1 * 5 + 1 * 8 + -1*11 + 1*14 \\\\\rm\implies -5 + 8 - 11 + 14 \\\\\rm\implies\boxed{\quad 6 \quad}$

Hence the required answer is 6.

A hot air balloon starts at a height of 6 feet above the ground and then rises at a rate of 20 feet each minute. Which equation

Leni [432]

Answer:

The height h it will travel in t minutes

Height h = 6 + 20(t)

Oh=20t + 6

Step-by-step explanation:

A hot air balloon starts at a height of 6 feet above the ground and then rises at a rate of 20 feet each minute.

Initial height h0 = 6 feet

Then it travel 29 feet each minute

Rate = 20 feet/ minute

The height h it will travel in t minutes

Height h = 6 + 20(t)

Answer:

The constant of proportionality is 3.50.

Step-by-step explanation:

We know that when y directly varies with x, such that

$y=kx$

The number 'k' is called the constant of proportionality.

Given the equation

$y=3.50x$

$y=kx$

$k=3.50$ ∵ $y=kx$

Here the value of k = 3.50, which is the constant of proportionality.

Therefore, the constant of proportionality is 3.50.
