Answer:
Step-by-step explanation:
We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.
We know that two inversely proportional quantities are in form , where y is inversely proportional to x and k is constant of variation.
Upon substituting and in above equation, we will get:
Let us solve for constant of variation.
Now, we will substitute in inversely proportion equation as:
Therefore, the formula for the given scenario would be .
You have the value for y, so you substitute that equation for y, times three because there are three yS.
So you have: 2x + 3y = 10
2x + 3 x 2x + 4 or 2x + 3(3x + 4)
so the answer would be B, 2x + 3(3x + 4)
The correct answer in its final stage is (C). The third choice.
L=Length W=Width P=Perimeter
L=3w-4
P=2w+22
P=2L+2w=2w+22 Answer: W=5
2L=22 L=11
L=11
11=3w-4
3w=15
W=5
Answer:
<h2>y + 4 = x</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept → (0, b).
The formula of a slope:
We have the points A(0, -4) → b = -4 and B(6, 2).
Calculate the slope:
Put the value of m and of b to the equation:
<em>add 4 to both sides</em>
