Answer:

<h2>40.8</h2>

Step-by-step explanation:

The formula of a distance from a point (x, y) to the origin:

d=\sqrt{x^2+y^2}

We have P(21, 35). Substitute:

d=\sqrt{21^2+35^2}=\sqrt{441+1225}=\sqrt{1666}\approx40.8

Which graph represents 7x+2y&lt; 8
professor190 [17]

Answer:

Graph C.

Step-by-step explanation:

<em>Hi there!</em>

Well let’s first put,

7x + 2y < 8

We need to single out y.

7x + 2y < 8

-7x to both sides

2y < -7x + 8

Divide everything by 2,

<u>y < -7/2x + 4</u>

Well the shade on the graph should be going down because it is y is less than,

And the y intercept should be at 4 with a dotted line and a slope of -7/2.

So graph C. Is correct.

<em>Hope this helps :)</em>

Jim rented a truck for one day. there was a base fee for $19.95 and there was an additional charge of 91 cents for each mile dri
beks73 [17]
First you’ll subtract the base fee, which is 19.95 from the price payed, 243.81

243.81
-19.95
223.86

Now take 223.86, your remainder and divide it by .91, you will get 246, meaning Jim traveled 246 miles.

Answer: Jim travelled 246 Miles.
