Answer:
28
Step-by-step explanation:
Answer:
y = 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 2) ← coordinates of intercepts
m = = 2
Note the line crosses the y- axis at (0, 2) ⇒ c = 2
y = 2x + 2 ← equation of line
Answer:
x = -5
Step-by-step explanation:
2/3x - 1/2 = 1/3 + 5/6x
add 1/2 to each side of the equation:
2/3x = 5/6 + 5/6x
subtract 2/3x from both sides:
0 = 5/6 + 1/6x
subtract 5/6 from both sides:
1/6x = - 5/6
multiply both sides by 6:
x = -5
Answer: The chance both cards will be a spade is .
Step-by-step explanation:
We know that , in a standard deck , the total number of cards = 52
The number of spades = 13
If a person selected 2 cards,
The total number of combination of selecting 2 cards out of 52 =
The number of combination of selecting 2 spade cards out of 13 =
Then , the probability that both cards will be a spade=
Hence, the chance both cards will be a spade is .
