Which first step for solving the given system using substitution results in an equation without fractions? Solve for x in the fi
lianna [129]

Answer:

solve for x in the second equation is correct

Step-by-step explanation:

Here is the complete question

Which first step for solving the given system using substitution results in an equation without fractions?

(2x+6y=7

(6x + 18y = 24.... 2

Solve for x in the first equation,

Solve for y in the first equation,

Solve for x in the second equation

The best equation to she will be equation 2 since all the coefficients are end numbers

Let us make x t subject f the formula from equation 2;

From 2: 6x+18y = 24

Subtract 18y from both sides

6x+18y-18y = 24-18y

6x = 24-18y

Divide through by 6

6x/6 = 24/6 - 18y/6

x = 4-3y.

You can see that the resulting expression of x is not a fraction. Hence solve for x in the second equation is correct

Which of the following is not an undefined term?<br><br> point<br> ray<br> line<br> plane
Mila [183]
<span>There are three undefined terms in geometry. These are points, line, and plane. Among the given choices, there is only one which is not an undefined term and that is ray. Ray is a part of a line that has an enpoint in one side and extends indefinitely on the opposite side. Hence, the answer is the second choice. </span>

The slope of the line below is -1. write the point-slope equation of the line using the coordinates of the labeled point.​
omeli [17]

Answer:

y+9=-1(x-4)

Step-by-step explanation:

Point Slope Form is:

y-y_1=m(x-x_1)

When:

'm' is the slope.

(x_1,y_1) is the coordinate.

We are given the slope of -1 and the coordinate of (4,-9).

So:

m=-1\\x_1=4\\y_1=-9

Using the information and replacing the values we get:

y+9=-1(x-4)

So, the line equation in point slope form should be: y+9=-1(x-4)
