Hello,

If an equation is an identity, then every value of the variable makes the egality true.

Generaly we resolve an equation in R.

In this case Sol=R

inn [45]
Hello,

Here is your answer:

The proper answer to your question is "1/18".

Here is how:

8*6=48
9*6=54
-
5*9=45
6*9=54

48-45=3

Which is 3/54!

3/3=1
54/3=18

Which means your answer is 1/18!

If you need anymore help feel free to ask me!

Hope this helps!

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
Julli [10]

Answer:

1) 6x+3y=5    

Step-by-step explanation:

1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}. Substitute the x and y values of the two points into the formula and solve:

m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2

So, the slope is -2.

2) Now, identify the slopes of the lines in the options. We already know the slope of y = -\frac{1}{2} x-7  is -\frac{1}{2} since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.

To find the slope of 6x + 3y = 5, isolate y to put the equations into slope-intercept form (y = mx + b format), and whatever the coefficient of the x-term is will be the slope.

6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}.

So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.

How to solve transformation problems in math
Molodets [167]
In this section we are going to see how knowledge of some fairly simple graphs can help us graph some more complicated graphs. Collectively the methods we’re going to be looking at in this section are called transformations.

Vertical Shifts
The first transformation we’ll look at is a vertical shift.
