Equations
• x² + y = 0 ... (1)
• x² - 4x - y = 0 ... (2)
Answer -> (x, y) = (2, -4)
Step-by-step solution:
From equation 2,
-> y = x² - 4x ... (3)
• Substitute y into equation 1
-> x² + (x² - 4x) = 0
-> 2x² - 4x = 0
-> 2x² = 4x
-> x²/x = 4/2
-> x = 2
• Put x = 2 in equation 3
-> y = (2)² - 4(2)
-> y = 4 - 8
-> y = -4
10+ ?= 49
⇒ ?= 49-10
⇒ ?= 39
10 plus 39 can give you 49~
.03*.03=.009 .009*.03=.000027 so the answer is .000027
If 1 in.= 2.54 cm, Then !9in. multiplied by 2.54 cm would be b. 48.26 cm
i am not shure what the answer is to this?
