Answer:

<h2>The graph has a domain of all real numbers.</h2><h2>The graph has a y-intercept at (0, 1).</h2>

Step-by-step explanation:

The given function is

$y=3x-1+2$

This is linear function, the domain and range of linear functions are always all real numbers, because they don't have any kind of restriction. So, the first option is right.

In addition, linear function are represented by a line which has interceptions with each axis. The interceptions with the vertical axis is when $x=0$ :

$y=3x-1+2\\y=3(0)+1=1$

So, the fourth option is right,

Similarly, the interception with the horizontal axis is when $y=0$ :

$0=3x-1+2\\-3x=+1\\x=-\frac{1}{3}$

This means the last option is not correct.

Therefore, all options that apply are

The graph has a domain of all real numbers.
The graph has a y-intercept at (0, 1).

A line segment is sometimes/always/never similar to another line segment, because we can sometimes/never/always map one into the

Fantom [35]

Answer:

A line segment is always similar to another line segment, because we can always map one into the other using only dilation a and rigid transformations

Step-by-step explanation:

we know that

A dilation is a Non-Rigid Transformations that change the structure of our original object. For example, it can make our object bigger or smaller using scaling.

The dilation produce similar figures

In this case, it would be lengthening or shortening a line. We can dilate any line to get it to any desired length we want.

A rigid transformation, is a transformation that preserves distance and angles, it does not change the size or shape of the figure. Reflections, translations, rotations, and combinations of these three transformations are rigid transformations.

If we have two line segments XY and WZ, then it is possible to use dilation and rigid transformations to map line segment XY to line segment WZ.

The first segment XY would map to the second segment WZ

therefore

A line segment is always similar to another line segment, because we can always map one into the other using only dilation a and rigid transformations

What is an equation of the line that passes through (-2,3) and is parallel to y=5x + 4.Give your answer in slope intercept form

9966 [12]

Answer:

y= 5x+13

Step-by-step explanation:

Slope- intercept form

y= mx +b, where m is the gradient and b is the y-intercept.

Parallel lines have the same gradient.

y= 5x +4

Gradient of given line= 5

Thus, gradient of line= 5

Subst. m=5 into the equation.

y= 5x +b

To find the value of b, substitute a coordinate

When x= -2, y=3,

3= 5(-2) +b

3= -10 +b

b= 3 +10 (+10 on both sides)

b= 13

Thus, the equation of the line is y= 5x +13.

Which is the highest value? 1/100, 1/400,1/500

NNADVOKAT [17]

1/100, 1/400, 1/500

Because the numerators are the same, we just need to compare the denominators.

100< 400< 500
⇒ 1/100 > 1/400 > 1/500

Therefore, the highest value is 1/100.

Hope this helps.
