Answer:
(3.5, 17)
Step-by-step explanation:
It would be nice to see the whole graph, so we can see where the functions cross.
Without that information, we can still eliminate unreasonable choices.
A) the quadratic at y=3.5 is well above the exponential
B) the most likely choice (3.5, 17)
C) at x=-8, the quadratic is above the exponential
D) neither graph goes anywhere near y = -8
Answer:
y = -2x + 2
Step-by-step explanation:
Given the following data;
Points on the x-axis (x1, x2) = (2, -1)
Points on the y-axis (y1, y2) = (-2, 4)
To find the equation of line in slope intercept form;
First of all, we would determine the slope of the line.
Mathematically, slope is given by the formula;
Substituting into the equation, we have;
Slope, m = -2
Next, we would use the following formula to find the equation of the line;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - (-2) = -2(x - 2)
y + 2 = -2x + 4
y = -2x + 4 - 2
y = -2x + 2 = mx + c
Answer:
C) It helps reduce carbon dioxide emissions
Step-by-step explanation:
- Methane being a vital greenhouse gas and produces 84 times more heat than carbon dioxide, its concentration varies across the seasons and can remain in the atmosphere for a period of 12 years.
- Methane has the ability to stay in the atmosphere without the oxygen for a longer duration.
- The gas can produce water vapor through the chemical reaction when it reaches the mesosphere and is most likely to produce clouds.
- <u>The environmental benefits of this gas is that it can produce energy by mass and are more refined than oil and creates less pollution and pollutants.</u>
Answer:
C. A chart displaying the amount of care pets require.
Step-by-step explanation:
(A). A picture of common house pets.
This wouldn't be effective since everyone knows what most common house pets look like.
(B). A picture of common pet supplies.
This wouldn't be effective since pet supplies vary with every animal.
(C). A chart displaying the amount of care pets require.
This would be the best choice since the image would show the required necessities for each different pet.
(D). A chart displaying which pets are the most popular.
This wouldn't be effective since popularity is mostly based on preference.
