Find the slope of the line passing throught the points (2, 2) and (4, 3).
The formula of a slope:

Substitute:

If the point (x, -1) lie on the same line, then the slope of line passing through the points (2, 2) and (x, -1) the same:
Substitute:

We have the equation:
<em>cross multiply</em>

<em>add 2 to both sides</em>

<h3>Answer: x = -4.</h3>
Multiply the price by (1 + sales tax).
85 x (1+0.07)
85 x 1.07 = 90.95
He will pay $90.95
This is the easiest way to solve this problem:
Imagine this represents how many combinations you can have for each of the 4 wheels (each blank spot for one wheel): __ __ __ __
For the first situation it says how many combos can we make if no digits are repeated.
We have 10 digits to use for the first wheel so put a 10 in the first slot
10 __ __ __
Since no digit can be repeated we only have 9 options for the second slot
10 9_ __ __
Same for the third slot, so only 8 options
<u>10</u> <u> 9 </u> <u> 8 </u> __
4th can't be repeated so only 7 options left
<u>10</u> <u> 9 </u> <u> 8 </u> <u> 7
</u><u>
</u>Multiply the four numbers together: 10*9*8*7 = 5040 combinations
For the next two do the same process as the one above.
If digits can be repeated? You have ten options for every wheel so it would look like this: <u>10</u> <u>10</u> <u>10</u> <u>10
</u>
10*10*10*10 = 10,000 combinations
If successive digits bust be different?
We have 10 for the first wheel, but second wheel only has 9 options because 2nd number can't be same as first. The third and fourth wheels also has 9 options for the same reason.
<u>10</u> <u> 9</u><u> </u> <u> 9 </u> <u> 9 </u>
10*9*9*9 = 7290 combinations
Answer:
10
Step-by-step explanation:
yellow
6+6+3=15
so
for green
4+4+2=10
<h2><u>Anѕwєr :</u></h2>
48/15 or 3 whole 3/15
<h2><u>Explαnαtion :</u></h2>
There are 4 pizzas and each have 12 slices. So,
→ Number of slices each pizza have = 12 slices
→ Number of slices 12 pizzas have = (12 × 4) slices
→ Number of slices 12 pizzas have = 48 slices
Now, we have to find the number of slices each person get if they are split evenly.
→ Number of people = 15
Let the the number of slices each person get if they are split evenly be x. So,
→ Total number of slices = Number of people × Number of slices each gets
→ 48 = 15x
→ <u>48/15 or 3 whole 3/15 = Number of slices each gets</u>
Therefore, the number of slices each person get if they are split evenly is 48/15.
