Answer:
10 liters of orange juice, 5 liters of champagne
Step-by-step explanation:
We can call the amount of orange juice and champagne as x and 15 - x liters respectively. Then, we can write the following equation:
1.50 * x + 12 * (15 - x) = 5 * 15
1.5x + 180 - 12x = 75
-10.5x + 180 = 75
-10.5x = -105
x = 10 so 15 - x = 15 - 10 = 5.
A)
The slope-intercept form:
m - slope
b - y-intercept
The formula of a slope:
We have the points (2, 5.1) and (-1, -0.5). Substitute:
Therefore we have:
Put the coordinates of the point (-1, -0.5) ot the equation:
<em>multiply both sides by 2</em>
<em>add to both sides</em>
<em>divide both sides by 2</em>
Answer:
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:
Therefore we have:
Put the coordinates of the point (-2, 3) to the equation of a line:
<em>subtract from both sides</em>
Answer:
Answer:
1. Because they are the same shape just that one is bigger.
2. Figure B is 3 times bigger than Figure A. Multiply Figure A by three.
3. Figure A is 3 times smaller than Figure B. Divide Figure B by three.
