The answer is A. You can get that in by plugging in and checking or by substitution. In order to use substitution here, you would plug in 3x + 3 into y in the first equation. You would then distribute the 2 and solve for x, which would give you 0. Then you could plug that into either equation to find that y = 3.
The first one is 212
and the second one is 158
so yes it is false they do not equal
We have that
y = 3x²<span>+ 2x + 1
step 1</span>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
y -1= (3x²+ 2x)
step 2
Factor the leading coefficient
y -1= 3*(x²+ 2/3x)
step 3
Complete the square. Remember to balance the equation by adding the same constants to each side
y -1+(1/3)= 3*(x²+ (2/3)x+(4/36))
y-2/3=3*(x+2/6)²
the vertex is the point (-2/6, 2/3)------> (-0.33,0.67)
the answer is
(-0.33,0.67)
The number of customers who visited more on first day = ( 5 x - 2)
<h2>
248 more people visited on the first day. </h2>
Step-by-step explanation:
The total number of customers visiting on first day = (6 x - 3)
The total number of customers visiting on second day = (x - 1)
The difference in the number of customers
= Number of customer visiting ( First day - Second Day)
= (6x - 3) - (x- 1) = 6 x - 3 - x + 1 = 5 x - 2
So, the number of customers who visited more on first day = ( 5 x - 2)
Now, when x = 50, ( 5 x - 2) = (5 (50) - 2) = 250 - 2 = 248
Hence, 248 more people visited on the first day.
Answer:
r≥2.5
it can't be < because the green dot is filled in
r is larger than 2.5 because the arrow goes to the right
