Answer:
2x - 7y + 17
Step-by-step explanation:
Subtracting the 2 expressions
2x - 4y + 6 - (3y - 11) ← distribute parenthesis by - 1 )
= 2x - 4y + 6 - 3y + 11 ← collect like terms
= 2x - 7y + 17
Answer:
y = - 2x + 3
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 =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1,1) ← 2 points on the line
m = = - 2
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = - 2x + 3 ← equation of line
Answer:
Step-by-step explanation:
From the question,
The total number of marbles in the bag,n(S) =10.
The number of black marbles,n(B)=7
The probability that both marbles are red means that, the first marble is red and the second marble is red.
P(1st marble is Black)=
Since Petra picked the first marble without replacing it, the total number of the marbles will reduce by 1. Same is applied to the number of black marbles.
This implies that,
P(2nd marble is black)
P(both are black)=
