Answer:

9n+18(2n-6)+13

Step-by-step explanation:

First, use distributive property to eliminate the parenthesis:

9n + 18(2n -6) + 13

9n + 36n - 108 + 13

Next, combine like terms:

9n + 36n - 108 + 13

45n - 108 + 13

45n + 121

Hope this helps!!

How to graph 9x+15y=45
leonid [27]
First you should rearrange to get it in the form y = mx + c, and you do this by subtracting the 9x from both sides and dividing by 15, which gives you:
y = (-9/15)x + 3

Now you know the y-intercept is 3, so you can mark that on as a point.
Then, to graph the gradient of -9/15, you go along 15 spaces to the right and 9 spaces down, or 15 to the left and 9 spaces up, and you repeat this until you run out of room. Then you just join the dots

I hope this helps! Let me know if you have any questions :)

PLEASE ANSWER!!! WILL MARK BRAINLIEST!!!!!!!!
tia_tia [17]

Let 'x' represent the total distance from point A to point B

During the first hour he gets 0.25 of the way there: 0.25x

During the second hour he covers an additional 0.2 of the distance: 0.2x

During the third hour, he covers 0.3 of the distance: 0.3x

The total distance the biker traveled is:

0.25x + 0.2x + 0.3x = (0.25 + 0.2 + 0.3)x = 0.75x

The biker has: x - 0.75x = (1 - 0.75)x = 0.25x of the total distance left to go.

A function is given by the equation h (x)=x 2 squared +6x-3. what is h (3)?
Leno4ka [110]
Your "<span>h (x)=x 2 squared +6x-3" is ambiguous.  If you meant "x squared," then you need only write x^2  OR  "x squared," but NOT "x 2 squared."

I will assume that by  "</span><span>h (x)=x 2 squared +6x-3" you actually meant:

</span><span>h(x)=x^2 +6x-3.  To find h(3), subst. 3 for x:  h(3) = (3)^2 + 6(3) - 3, or

h(3) = 9 + 18 - 3, or h(3) = 24.</span>

Answer:

Lines c and b, f and d (option b)

Step-by-step explanation:

To prove whether the lines satisfy the condition of being a transversal to another, let's prove one of the conditions wrong, and thus the answer -

Option 1:

Here lines a and b do not correspond to one another provided they are both transversals, thus don't act as transversals to one another, they simply intersect at a given point.

Option 2:

All conditions are met, lines c and b correspond with one another such that b is a transversal to both c and d. Lines f and d correspond with one another such that f is a transversal to both d and c.

Option 3:

Lines c and d are both not transversals, thus clearly don't act as transversals to one another.

Option 4:

Lines c and d are both not transversals, thus clearly don't act as transversals to one another.

Find the slope of the line with x intercept 9 and y intercept of -2
elena-s [515]

Answer:

2/9

Step-by-step explanation:

Find the slope of the line with x intercept 9 and y intercept of -2

Given that the equation of the line is y = mx+b

x intercept occurs when y = 0

The coordinate of x intercept is (9,0)

y intercept occurs at x = 0

The coordinate of y intercept is (0, -2)

Slope m = y2-y1/x2-x1

m = -2-0/0-9

m = -2/-9

m = 2/9

Hence the required slope is 2/9
