Is this a direct variation?
y = 2x

Answer:

$16.83

Step-by-step explanation:

If the usual price is $19.80 and they are on sale for 85% of the usual price, you can set this up in the form of a proportion.

[tex]\frac{85}{100} = \frac{x}{19.80}[/tex]

With this, you first multiply 85*19.80 and then you divide that answer by 100 to solve for x, the sale price.

Another way you can approach it is by changing 85% into it's decimal form (.85) and multiplying this by the original price (19.80).

The measure of MN from the diagram is 6

From the given triangle, the expression below is true;

ML/LK = MN/NO

Given the following parameters

ML = 4

LK = 10

NO= 15

Substitute the given parameters into the formula

4/10 = MN/15

Cross multiply

10MN = 4 * 15

10MN = 60

MN = 6

Hence the measure of MN from the diagram is 6

Answer:

1) (5x-10)(-2x+-10)=9

2)(3x-0)=9

Step-by-step explanation:

The property used for the expression (5x-10)(-2x+-10)=9 is distributive.

This property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the step is 5(x-2) -2(x-5)=9. The step will be solved by the distributive property. By multiplying the two parts with each other and simplifying them.

Let's solve your equation step-by-step.

12(6t−4)=3t−2

Step 1: Simplify both sides of the equation.

12(6t−4)=3t−2

(12)(6t)+(12)(−4)=3t+−2(Distribute)

3t+−2=3t+−2

3t−2=3t−2

Step 2: Subtract 3t from both sides.

3t−2−3t=3t−2−3t

−2=−2

Step 3: Add 2 to both sides.

−2+2=−2+2

Answer:

x= 1/6

Step-by-step explanation:

Multiply all the numbers by x and cancel:

3/5 + 2x =5.6x

2x + 3/5 = 5.6x (Simplify both sides of the equation)

2x + 3/5 - 5.6x = 5.6x - 5.6x (Subtract 5.6x from both sides)

-3.6x + 3/5 = 0

-3.6x + 3/5 - 3/5 = 0 - 3/5 (Subtract 3/5 from both sides)

-3.6 = -3/5

-3.6x/-3.6 = -3/5 / -3.6 (Divide both sides by -3.6)

x = 1/6

The conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.

To of identify the type of conic section from an equation whether it is circle, or ellipse a let suppose the equation as,

[tex]Ax^2+By^2+Cx+Dy+E=0[/tex]

In this equation, if,

[tex]A\neq B[/tex]

Then it is the equation of circle.

If In this equation,

[tex]A\neq B[/tex]

But both A and B has same sign (either positive or negative) then it is the equation of ellipse.

The given equation in the problem is,

[tex]3x^2 - 7x+ 8y^2 - 2y+ 1 = 0[/tex]

Here, in the equation,

[tex]A=3\\B=8[/tex]

The A is not equal to B but the sign of both are positive. Hence this equation is the equation of ellipse.

Hence, the conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.
