Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
Answer:
x = -4
Step-by-step explanation:
x/8 = -1/2
-1/2 = ?/8
2 * 4 = 8
-1 * 4 = -4
2 * 4 = 8
-1/2 = -4/8
x = -4
Answer:
120 student and 80 adult tickets
Step-by-step explanation:
8x + 10y = 1760
x + y = 200
There are 16 oz in 1 pound.
34 lbs = 544 oz
Therefore, 34 lbs = 544 oz
The answer is going to be s. The proportions are (short leg/long leg) , and the appropriate long leg for h is s.
