For the 2nd equation u have to divide 3 for both sides so y can be alone so it will be y=3x+6
Answer:
50 seconds
Step-by-step explanation:
Well, if the bird is travelling 8 m/s then you divide 400 by 8 to figure out how long it would take it to fly, since 8 x 50= 400.
Answer: The number of points added for r right answers is 12r. The number of points taken away for w wrong answers is 4w, so Olga's total points will be
... 12r -4w
To win, she needs this number to be more than 400. Your inequality is ...
... 12r -4w > 400
Answer:
first and fourth
Step-by-step explanation:
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ±
= ± 2
that is x = - 2, x = 2
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ±
= ± 2
that is x = - 2, x = 2
Answer:
Yes
Step-by-step explanation:
6 + 8y - 3+ 4y
Add like terms
(8y+4y)+(6-3)
12y+3
