Answer:
The third (y=2x–5)
Step-by-step explanation:
y=2x–5
if we substitute then:
3=2(4)–5
3=8–5
Answer:
y=3x+2
Step-by-step explanation:
y=mx+b
we have m here so
y=3x+b
then the 2 is the y-intercept
y=3x+2
Answer:
1/3
Step-by-step explanation:
If you're talking about a 6-sided die, then there are 6 sides. Rolling a 2 or a 3 would be a 2/6 chance. To simplify if from there, you can also say that there is a 1/3 chance.
Answer: Add 9 to both sides to complete the square
Step-by-step explanation:
The formula for the number you need to add to complete the square is (b/2)^2. In this case, b = -6, so:
(b/2)^2 = (-6/2)^2 = (-3)^2 = 9.
(After adding 9 to both sides, you will get x^2 - 6x + 9 = 14 which can be factored to (x - 3)^2 = 14)
Answer: x = √141
Step-by-step explanation: 22² + x² = 25² -> 484 + x² = 625
625 - 484 = 141
x² = 141
x = √141
