the answer for 12 would be 63
Step-by-step explanation:
7 x 9 x 1
Answer:
y = -
x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m =
=
= - 
Since the line crosses the y- axis at (0, 6) ⇒ b = 6
y = -
x + 6 ← equation of line
Hi Grant.
(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.
3x + 2x; 5 - 9; we result with: 5x - 4
Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.
(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.
5x - 4x; -4 - 3; we result with x - 7.
Your answer is A.) x - 7.
I hope this helps!
Answer:

Step-by-step explanation:
3 envelopes having 2 red card
2 envelopes having 1 red card and 1 black card
1 envelope having 2 black cards
We are given that . An envelope is selected at random and a card is withdrawn and found to be red.
So, No. of ways of envelope having red card = 3+2 = 5
No. of required ways of envelope having 1 red card and 1 black card = 2
So, probability of getting an envelope having 1 red card and 1 black card = 
Hence The chance the other card is black is
