What is the distance between point (7,9) and point (-2,7)

Answer:

√85 or 9.22

Step-by-step explanation:

For this, you'd want to use the distance formula, which is just something you'd eventually memorize.

Distance = \sqrt{(x_{2}- x_{1})^{2} + (y_{2}- y_{1})^{2}}

Then, you'd plug in the values. Something to keep in mind is the coordinate that is farther right will be (x_{2} ,y_{2}), since (x_{2}- x_{1}) is supposed to represent the change in x (and same with the y).

d = √( (7 - (-2))² + (9 - 7)²)

= √( (9²) + 2²)

= √(81 + 4)

= √85

= 9.22

I hope this helps!

A box of chocolates costs $9. How much will 15 boxes of chocolate cost? A. $119 b. $120 c. $125 d. $135 e. $145
PolarNik [594]

To solve this problem, we must multiply the cost of one box of chocolates ($9) by the number of boxes of chocolates purchased (15) to find the total cost of the chocolates.

$9 * 15 = $135

Therefore, your answer is $135, or option D.

Hope this helps!

A rental car agency rents cars for $32 per day. They also charge $0.15 per mile driven. If you are taking a 5-day trip and have
xz_007 [3.2K]
So the equation is 32x+0.15y = $250
You know that you’re going to a 5-day trip so you can change x to 5
32(5)+0.15y = $250
You multiply 32 by 5 = 160
$160+0.15y = $250
And to simplify the equation(to make it easier) you subtract 160 on both sides
0.15y = $90
Now you’re trying to find y, so divide 90 by 0.15 to find the maximum of miles you can drive.
y = 600 mi
The maximum amount of miles you can drive is 600

Graph:
I can’t show any pictures sorry
But this is how you do it
Make a number line
Graph 600 with a closed circle, like this: ●
Then make an line going to the left(because you can’t go any more than 600)

Hope this helps! :^)
