The answer is: [B]: " 15 " .
____________________________________________________
Explanation:
____________________________________________________
"112" and "(7x + 7)" are the measurements of 2 (TWO) vertical angles;

and all vertical angles are equal; so, to solve for "x" ;

7x + 7 = 112 ;

Subtract "7" from EACH SIDE of the equation:

7x + 7 - 7 = 112 - 7 ;

to get:

7x = 105 ;

Now, divide EACH SIDE of the equation by "7" ; to isolate "x" on one side of the equation; and to solve for "x" ;

7x / 7 = 105 / 7 ;

to get: x = 15 ; which is:

Which of the following quadratic regression equations best fits the data shown below?

bazaltina [42]

Answer:

Step-by-step explanation:

In order to do this, you have to know how to use your calculator's regression equation function.

First enter in the data. Hit "stat" then 1:Edit and enter all the x values into L1. After each value, hit enter. When you're done with the x list, arrow over to L2 and enter in all the y-values. If there are already values there you need to clear, arrow up to highlight L1, hit "clear", then "enter" and the values will disappear. Do that for both lists if you need to.

After the data is listed in L1 and L2, hit "stat" again and arrow over to "Calc". Hit 5:QuadReg. If you have a TI 83, your equation will be there for you. If you have a TI 84, you'll need to arrow down to "calculate" to get the equation. Regardless, the equation is

$y=3.48x^2+1.22x+3.44$ , the last choice in your options.

What is the solution to the system of equations? O (-6,-) O (-2, 6) O (6,2) O (-2,-6)

damaskus [11]

Answer:

Option (1)

Step-by-step explanation:

System of equations is represented by two straight lines on a graph.

And solution of the system of equations is the point of intersection of these lines.

From the graph attached, two straight lines represent the system of equations.

And the point of intersection of these lines is the solution.

Therefore, solution of the system of equations will be (-6, -2).

Option (1) will be the correct option.

a function f(x) is described by the ordered pair (x,y). if given the function is translated 2 units to the right and then reflec

OleMash [197]

The ordered pairs would be (x-2, -y).

Translating a graph to the right subtracts the number of units from the x-coordinate.

Reflecting across the x-axis negates the y-coordinate.
