Estimate the values of x when y=1

Mathematics
1 answer:
Cerrena [4.2K]3 years ago
7 0

Step-by-step explanation:

if one were to put the y value the equation they could find out what x is for a certain value of y

putting the value of y(1), we get the equation

1=4x-1

2=4x

x=0.5

the value of x when y is 1 is =0.5

NOTE: I got this explanation on brainy on someone else I am not taking the credit

The function f is defined as follows for the domain given.
Blizzard [7]

Answer:

range ={-6,-2,4,8}

Step-by-step explanation:

The given function is

f(x) = 2x + 2

The domain is given as:

domain = {-4,-2, 1,3}

To find the range, we plug in the domain and solve for the corresponding range value.

When x=-4,

f( - 4) =2 \times   - 4 + 2 =  - 8 + 2 =  - 6

When x=-2,

f( - 2) =2 \times   - 2+ 2 =  - 4+ 2 =  - 2

When x=1,

f( 1) =2 \times   1 + 2 =  2 + 2 = 4

When x=3,

f( 3) =2 \times  3 + 2 = 6 + 2 =  8

Therefore the range is {-6,-2,4,8}

Describe how to graph a line given an equation in standard form.
Archy [21]
This is pretty simple. So a standard form equation is probably something like this: 2x+8y=10. 
We have to get that equation right there into a slope intercept, which is just isolating the variable y. 
 2x+8y=16    
-2x        -2x       Subtract the x value. 
------------------
 (8y=16-2x)/8  Divide the whole equation by 8 to isolate the y value.  
------------------
 y=2-1/4x
------------------
The fraction with the variable x is the slope. In this case, the slope is -1/4, so meaning it goes down one unit and goes right 4. 
------------------
The 2 is the y-intercept. (0, 2)

I’m so confused on what numbers l should put into the boxes
Serggg [28]

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The lines for the given statements can be plotted as shown below.

<h3>What is the equation of a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is y-intercept.

The lines for the given statements can be plotted as shown below.

The coordinate grid can be filled as,

1)

x        0         3         1

y        3         0         2

2.)

x        0         1         -1

y         1         0          2

3.)

x         0         4         -1

y         -2         0          2

4.)

x         0         1           1

y         -2         0         -2

Which number line represents the solution set for the inequality 2x- 6&gt;6 (x-2)+8
kirill [66]

Answer:

The inequality is

2 x - 6 > 6(x -2) +8

To solve the inequality we will first use distributive property with respect to multiplication over subtraction

And then bring constant on one side and variable on another side keeping the inequality maintained

2 x -6 > 6 x -12 + 8

2 x -6 > 6 x - 4

6 x - 2 x< -6+4

4 x < -2

Dividing both sides by 2

x <  \frac{-1}{2}

Now i will draw the graph of above function.
