Answer:
x = 1; y = 2
Step-by-step explanation:
y = 3x − 1
y = -4x + 6
In the first equation, y = 3x - 1.
Substitute 3x - 1 for y in the second equation.
3x - 1 = -4x + 6
7x = 7
x = 1
Substitute 1 for x in the first original equation.
y = 3x - 1
y = 3(1) - 1
y = 3 - 1
y = 2
Solution: x = 1; y = 2
False. Since the probability of one side of the coin is 3/10, the other must be 7/10.
Answer:
nm
Step-by-step explanation:
n × m = nm ways
19 + 5a⁴ - 3b²
19 + 5(2)⁴ - 3(-4)²
19 + 5(16) - 3(16)
19 + 80 - 48
99 - 48
