Answer:
- construct PQ
- construct circles of radius PQ centered at P and Q
- label one of the points of intersection R
- Construct PR and QR
Step-by-step explanation:
You should actually do this some time. It will help you understand the construction process and help you remember the steps. It may even help you figure out why it works.
4 one coefficient and three variables
Answer:
x= 5
Step-by-step explanation:
You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.
Answer:
Adding them together. x = 3/2, y = 8
Step-by-step explanation:
Adding because we want to get rid of a variable. If we add, 2x + 6x = 8x, 1/2 * y + (-1/2 * y) = 0, and 7 + 5 = 12. Adding gets rid of the y variable.
By adding we get that 8x = 12 which gives us x = 12/8 = 3/2
Substituting this back into either equation will give us y = 8.
F(x) = 5x − 1
and g(x) = 3x − 9
g(x) - f(x) = (3x − 9) - (5x − 1) ===> -2x-8
