method for solving 5(x-2) -2(x-5)=9 is shown below. Identify the property used to obtain each of the two indicated steps.
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.

Which conic section is represented by the following equation? 3x2 – 7x 8y2 – 2y 1 = 0 circle ellipse parabola hyperbola.
The conic section which is represented by the provide equation is the equation of ellipse and represent ellipse conic section.
How to identify the type of conic section from an equation?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.

what is the point slope form of (-7,5) , (1,-1)
Answer:
y-5=-2/3(x-(-7))
Step-by-step explanation:
I just learned this recently as well so bare with me.
So the point slope form is y-y1=m(x-x1)
So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4
So now, we just have to plug in the numbers.
So y-5=-2/3(x-(-7)).
I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.
I hope this helped.

Use 3.14 for PI
Answer:
200.96 millimeters²
Step-by-step explanation:
How do we find the area of a circle?
The area of a circle is πr², where r = radius. We're given the radius as 8 millimeters, and we're going to approximate pi as 3.14.Solving
3.14 × 8²3.14 × 64200.96Therefore, the area is 200.96 millimeters².
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Solution:
We know that:
Radius = 8 mmArea of circle = πr²Finding the area of the circle.
Area of circle = πr²=> Area of circle = 3.14 x 8²=> Area of circle = 3.14 x 64=> Area of circle = 200.96 mm²Find the midpoint of segment EF if E (5,-2) F(1,-8) URGENT

3/5x+2=5.6 what is x?
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
