George solved the following system of equations using substitution.
y = 4.3 – 21
12x – 3y = 63
He decided there is no solution. After the following steps:
y= (4x – 21)
12x - 3(4x – 21) = 63
12:- 12.c + 63 = 63
63 = 63
Is George correct in his conclusion? If not choose the correct solution below. If he is correct, select that choice.
A) George is correct with no solution.
B) He is not right. There are infinitely many solutions.
C) He is not right. The solution is (63,63)
Answer:
B
Step-by-step explanation:
-4x + y = -21
12x -3y = 63
-4/12 = -1/3
1/-3 = -1/3
-21/63 = -1/3
If we graph the two lines, we can discover that are the same, so they have infinite points in common

There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy. Alia keeps all the cards down on a table with the pictures hidden and mixes them up. She then turns over one card and finds the picture of a rose on it. She removes this card from the table and turns over another card without looking. What is the probability that the card that Alia turns over has a rose on it? (1 point)
Group of answer choices
4 over 5
5 over 7
4 over 7
5 over 8
Answer:
P = 4/7
Step-by-step explanation:
There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy.
Then we have a total of 8 cards.
Now Alia turns over one card, and this card has a picture of a rose, then she removes it.
This means that now there are 4 cards with a picture of a rose and 3 cards with a picture of a daisy, so now we have a total of 7 cards.
We want to find the probability that the next turned card has also a rose on it.
This will be equal to the quotient between the number of cards with a rose on it (4 cards) and the total number of cards (7)
Then the probability is:
P = 4/7

Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels
The question is incomplete:
Sasha buys bagels for her garage sale customers she buys all the chocolate chip bagels and half of the plain bagels each bagel cost 2.50 how much does Sasha spend on bagels? The table that shows the types of bagels sold at the bagel shop on Friday is attached.
a. $70
b. $20
c. $90
d. $110
Answer:
c. $90
Step-by-step explanation:
First, you need to find the amount of bagels that Sasha purchased. The statement indicates that she buys all the chocolate chip bagels and the table shows that 28 chocolate chips bagels were sold, so that's the amount she purchased of this type of bagels. Also, the statement indicates that she buys half of the plain bagels and the table says that 16 plain bagels were sold, so you have to divide this amount by 2:
16/2=8
Then, you have to add the amount of chocolate chips bagels plus the amount of plain bagels that Sasha purchased:
28+8=36
Now that you know the amount of bagels that Sasha purchased, you have to multiply this for 2.50 that is the price per bagel:
36*2.50=90
According to this, the answer is that Sasha spends $90 on bagels.

What is parabola?A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix). The issue of parabola is intertwined with the topic of conic sections, and all of its principles are discussed here.
In the given figure,
The curve represent the parabola
Since the curve is passing through
(0,9) from the Y axis and touches x axis at infinity
Now we can use hit and trial method to find the exact equation
So we plot the figure one by one
Hence,
we get the correct equation,
y = [tex](1/2)^{x - 3} + 1[/tex]

A rectangle has a width represented by the expression-2x+20. The length of the rectangle is 6 more than twice the width. Which expression represents the area of the rectangle?
The perimeter of a rectangle is given by:
[tex]\boxed{\bold{Perimeter = 2 (length + width)}}[/tex]
In the problem we have these data:
Length = a Width = -2x + 20 Perimeter = 6 + 2 (-2x + 20)
We replace the data in the equation of the perimeter:
6 + 2 (-2x + 20) = 2 (a - 2x + 20)
We apply distributive property:
6 - 4x + 40 = 2a - 4x + 40
6 = 2a
6 ÷ 2 = a
3 = a
⇒ Length = 3
The area of the rectangle is given by:
[tex]\boxed{\bold{Area = 2 (length + width)}}[/tex]
We have these data:
Length = 3 Width = -2x + 20
We replace the data in the equation of the area:
Area = (3) (- 2x + 20)
We apply the distributive property and obtain:
Area = -6x + 60
The expression representing the area of the rectangle will be -6x + 60

The area of a circle is πr².
We have,
The pier is in the shape of a semicircle.
So,
The area of a semicircle is half of the area of a circle with the same diameter.
The area of a circle with a diameter of 56m is:
A = πr² = π(28)² = 2463.23 m²
So,
The area of the semicircle is:
A/2 = 2463.23/2= 1231.62 m²
