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:
FC = 27, QC = 18
Step-by-step explanation:
The centroid Q is the way along CF , therefore, QF is half as long as CQ
Given FQ = 9, then
QC = 2 × 9 = 18
FC = FQ + QC = 9 + 18 = 27
Answer:
19) n = -14
20) x = 4
21) b= -14
22) x = 2
23) x = -1
24) x = -9
Step-by-step explanation:
19) Use the distributive property to get rid of the parentheses. You will get: 20-4n = 76. So, n = -14.
20) Multiply both sides of the equation by 2 to get: -8 + x = -4. So, x = 4
21) Add 3 to both sides to get: = -1. So, b = -14
22) Use the distributive property to get rid of the parentheses. You will get: -40 - 5x = -50. Then, add 40 to both sides to get: -5x = -10. So, x = 2.
23) Use the distributive property to get rid of the parentheses. You will get: -72 = -64 + 8x. Then, add 64 to both sides to get: -8 = 8x. So, x = -1
24) Add 2 to both sides to get: = -3. So, x = -9
Hope this helps :)
