Answer:
the cost for the large popcorn and the small drink is $4 and $3 respectively
Step-by-step explanation:
The computation of the cost for the large popcorn and the small drink is shown below:
Let us assume the cost of the large popcorn be x
ANd, the small drink cost be y
Now as per the question
2x + 4y = $20
2x + 2y = $14
Now subtract equation 2 from equation 1
2y = $6
y = $3
Now for x it is
2x + 12 = $20
2x = $8
x = $4
Hence, the cost for the large popcorn and the small drink is $4 and $3 respectively

help plz im confused
Answer:
x = 16
Step-by-step explanation:
Δ ABC and Δ ADE are similar , thus the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{AD}[/tex] = [tex]\frac{BC}{DE}[/tex] , substitute values
[tex]\frac{x}{x+6}[/tex] = [tex]\frac{8}{11}[/tex] ( cross- multiply )
11x = 8(x + 6)
11x = 8x + 48 ( subtract 8x from both sides )
3x = 48 ( divide both sides by 3 )
x = 16

Can a solution to this equation be 3, because then both sides would have divide by 0?
Answer:
Step-by-step explanation:
If we multiply x - 7 by x - 3, we get x^2 - 10x + 21. This shows that the LCD is x^2 - 10x + 21, or (x - 7)(x - 3). Let's convert each of the two fractions on the right to their equivalents, with the LCD in the denominator.
Multiplying both the numerator and the denominator of 6/(x - 7) by (x - 3), we get 6(x - 3) over x^2 - 10x + 21, which is the LCD.
Similarly, we get 5(x - 7) over x^2 - 10x + 21.
Now all three of the original fractions have the same denominator, x^2 - 10x + 21. We can now "drop" the LCD, which leaves us with:
x^2 - 29 = 6(x - 3) + 5(x - 7)
Performing the indicated multiplications, we get:
x^2 - 29 = 6x - 18 + 5x - 35. Combining like terms:
x^2 - 29 = 11x - 53, or x^2 - 11x + 24 = 0
This factors as follows: x^2 - 11x + 24 = 0 = (x - 3)(X - 8) = 0
Then the preliminary solutions are x = 3 and x = 8. Unfortunately, we cannot substitute x = 3 into the original equation, because that would lead to division by zero. The only valid solution is x = 8, since every term of the original equation is defined at x = 8, and the equation is true for this value.
Repeat: 3 cannot be a solution because the 3rd fraction is undefined at
x = 3. So we have only one valid solution (8) with no other solution to multiply by 8.
Answer: You may divide by a variable. But only if you know the variable is non-zero. So, if setting the variable to zero makes both sides of the equation zero, we have a solution that that variable is 0, or the equation with the variable divided out holds. E.g. solve x(x-1) = 0.

How do you graph a quadratic function?
Answer:
Step-by-step explanation:
Compare the equation with the standard form, y=ax2+bx+c . Since the value of a is positive, the parabola opens up.
So, y=0 implies, by the zero product property, x+4=0 or x−2=0 .
Substitute x=−1 in the equation y=−x2−2x+8 to find the y -coordinate of the vertex.
find the solution for the following equation using the algebraic method: 3x^2+10x=8

Z/Z
1/4 (z)+1/4 (z)

Answer:
Step-by-step explanation:
An ellipse is defined as the locus of all points,the sum of whose from two given points is constant. Here z is a complex number whose distance from (1,0) and (−1,0) is constant. Hence the locus of z is an ellipse in the complex plane. Hence z will be all those points which lies on the ellipse with focus (−1,0) and (1,0).
