Lily paid $19.16 for a 1kg apple basket. This amount includes a tax of 3%. What was the cost of the apple before tax?

To get this answer, you add up the corresponding coordinates.

The x coordinates add to -4+4 = 0

The y coordinates add to 7+1 = 8

The z coordinates add to 2+(-3) = -1

Another way to express this is to consider

u = (a,b,c)

v = (d,e,f)

which add to u+v = (a+d,b+e,c+f)

There is nothing to indicate the graph is not of a polynomial function. Its zeros are the x=intercepts: -2, 3, 5. There are 3 of them, so that is the least degree the polynomial might have.

Answer:

a) y = 2x -2

b) Equation: q = 2p - 2  ----(1)

p² + q² = 4   ----(2)

The coordinates of C may be (0, -2) or (6/5, 8/5)

Step-by-step explanation:

a) Step 1: Find the coordinates of midpoint, P of AB

x-co-ordinate of P = (x₁ + x₂)/2 = (-1 + 7)/2 = 3

y- co-ordinate of P = (y₁ + y₂)/2 = (6 + 2)/2 = 4

Step 2: Determine the gradient, m₂ of perpendicular bisector of AB

For perpendicular lines, m₁ * m₂ = -1 where m₁ is slope of AB

m₁ = (2 - 6)/(7 - -1) = -4/8 = -1/2

-1/2 * m₂ = -1

m₂ = 2

Step 3: Deriving the equation of the perpendicular bisector in the form y = mx + c

y - y₁ = m(x - x₁); substituting the values of the midpoints of the line

y - 4 = 2(x - 3)

y - 4 = 2x - 6

y = 2x -2

b) Step 1: Derive the values of the p and using the formula of distance between two points:

y = 2x - 2

therefore q = 2p - 2  ----(1)

OC = √(x₂ -x₁)² + (y₂ - y₁)²

2 = √(p - 0)² + ( q - 0)²

2 = √p² + q²

squaring both sides

p² + q² = 4   ----(2)

Substituting (1) in (2)

p² + (2p - 2)² = 4

p² + 4p² - 8p + 4 = 4

5p² - 8p = 0

p(5p - 8) = 0

Therefore p = 0 or 5p - 8 = 0

p = 0 or p = 8/5

Substituting p = 0 in (1)

q = -2

substituting p = 8/5 in (1)

q = 2(8/5) - 2

q = 16/5 - 2

q = 6/5

Hence the coordinates of C may be (0, -2) or (6/5, 8/5)

The answer is

[tex]48^{9} - 72x^{7} +36x^{5}[/tex]

Step-by-step explanation:

1. How many terms are in the expression?

The terms are sorted by looking at the sing/indicator in front of them. For this expression there are 4 terms

13x, -2y, -5x, and 8

2. Which terms are “like terms”?

13x and -5x are like terms.

3. Are there any constants? If so, what are they?

Yes there is a constant terms and it's 8

4. What are the variables in the expression?

The variables in this expression are x, and y

5. What are the coefficients in the expression?

Coefficients is the number in front of variables in this expression the coefficients are 13, -2, and -5

Answer:

there are 4 terms

13x and - 5x are like terms

+8 is the only constant term

yes there are variables

the coefficients are ,13,-2, and-5

Step-by-step explanation:

1. A term is any section of a equation that has to do with an operation such as multipulcation or subtraction.

2. like terms are terms that share a common variable with another term.

3. Constants are number in an equation that have no variable and don't change

4. variables are letters used in an equation

5. coeffecients are the number a next to variables make sure to take the negitave or positive sign in front of it to account when solving your problem. variables with out a number in front of them always have a coefficient of 1.

Answer:

1. 1 real solution

2. 2 real solutions

3. Two complex solutions

Step-by-step explanation:

y = 3x^2- 6x + 3

This has 1 real solutions.

y= -x^2 - 4x + 7

This has 2 real solutions.

y = -2x^2 + 9x – 11

This has 2 complex solutions.

The number of unique solutions each equation has is required.

[tex]y=3x^2-6x+3[/tex] has one real solution.

[tex]y=-x^2-4x+7[/tex] has two real solutions.

[tex]y=-2x^2+9x-11[/tex] has two complex solutions.

The number of solutions is determined by the value of the discriminant.

Let us find the determinant of each equation

[tex]y=3x^2-6x+3[/tex]

[tex]D=b^2-4ac\\\Rightarrow D=6^2-4\times 3\times 3\\\Rightarrow D=36-36\\\Rightarrow D=0[/tex]

The equation has one real solution.

[tex]y=-x^2-4x+7[/tex]

[tex]D=(-4)^2-4\times (-1)\times 7\\\Rightarrow D=16+28\\\Rightarrow D=44\\\Rightarrow D>0[/tex]

The equation has two real solutions.

[tex]y=-2x^2+9x-11[/tex]

[tex]D=9^2-4\times (-2)\times (-11)\\\Rightarrow D=81-88=-7\\\Rightarrow D<0[/tex]

The equation has two complex solutions.

The distance between the two cities Dallas and Houston is 240 miles

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Given that:

1 inch = 50 miles

Hence:

4.8 inches = 4.8 inch * 50 miles per inch = 240 miles

The distance between the two cities Dallas and Houston is 240 miles
