Two and four tenths times a number minus three is greater than one and six tenths times the number minus four and one tenth

diamong [38]

Let's first turn all the words into numbers:

Two and four tenths = 2.4

One and six tenths = 1.6

Four and one tenth = 4.1

Now lets represent "a number" as x.

Then translate the wording into a linear equation:

$2.4x-3>1.6x-4.1$

Simplify and isolate the variable:

$0.8x>-1.1$

Divide by 0.8

x>1.375 or x>1 3/8

Evaluate |x + y|, for x = 8 and y = -15. 7 -7 23 -23

natka813 [3]

Answer:

Step-by-step explanation:

When evaluating absolute values, a great way to remember what they do is simple. No matter the number, whether it is negative or positive, the number(s) IN THE absolute values are ALWAYS positive.

So, |x + y| is then substituted with the numbers given for the variables.

|x + y|

|8 - 15|

|-7|

Hope this helps!

Find the equation of a line that passes through left parenthesis 1 comma 6 right parenthesis(1,6) and is parallel to the graph o

max2010maxim [7]

Answer:

The equation for the new line in slope-intercept form is:

$y=4x+2$

Step-by-step explanation:

Since they give us an equation in slope-intercept form "y=4x+5", it is easy to extract the slope the new parallel line to this should have : "4" (same slope as the reference line)

We are also given a point the new line should go through : "(1, 6)"

So we can use the "point-slope" form of a line to find the equation of this new line:

$y-y_0=m(x=x_0)\\y=m(x-x_0)+y_0$

which for our case is:

$y=m(x-x_0)+y_0\\y=4\,(x-1)+6\\y=4x-4+6\\y=4x+2$
