You have to change each groschen to be equal to Y and then input it into a graphing calculator to get the points
Answer:
Step-by-step explanation:
Allow me to rewrite your question:
<em>Use graphing to find the solutions to the system of equation </em><em>-y=4 and 2x+y=-1 </em>
Here is my answer:
Given:
<em>-y=4 <=> y = </em>
- 2x + y = -1 <=> y = -2x -1
So we graph the two lines on the plot as the following photo, we can see that:
x = -3 y =5 and
x = 1, y- = -3
Hope it will find you well

Answer:
and
Step-by-step explanation:
Let
x -----> the altitude of a commercial aircraft
we know that
The expression " A minimum altitude of 29,000 feet" is equal to
All real numbers greater than or equal to 29,000 ft
The expression " A maximum altitude of 41,000 feet" is equal to
All real numbers less than or equal to 41,000 ft
therefore
The compound inequality is equal to
and
All real numbers greater than or equal to 29,000 ft and less than or equal to 41,000 ft
The solution is the interval ------> [29,000,41,000]
F(x) = ㏑(x² - 4)
Domain: {-2 ≤ x ≤ 2}, or [-2, 2]
Domain: {-2 ≤ x ≤ 2}, or [-2, 2]
