y ≥ −4x − 2
Step-by-step explanation:
Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
The x value in the second equation (y+2) is substituted for the x in the first equation in...
Answer A.
Answer:
Step-by-step explanation:
An urn contains two blue balls (denoted 
) and three white balls (denoted 
).
In the selection, a ball is picked and replaced.
From the attached probability tree, the possible outcomes are:
(a)If the first ball drawn is blue
Number of Outcomes =10
The probability that the first ball drawn is blue 
(b)If only white balls are drawn
Number of Outcomes =9
Probability that only white balls are drawn
