The slope is an expression of the change in y after a change in x.
Usually, this is expressed with a ratio, with the difference in y first.
The formula for slope is written as
.
Our points are
and
.
Of course, the difference is just subtracting one from the other, but you'll get either a positive or negative value depending on which way you subtract. That's all fine and dandy if you handle the differences in x and y in the same way like in the formula, because any unwanted negatives get cancelled out...it's not important.
Anyways, let's plug our points (2, 8) and (6, 12) into the slope formula.
Any number divided by 1 stays the same, so we can leave out the /1 and just have our slope be
1.
10% of 180 is 18, so over 2 years that is 20%, so 36 dollars.
Answer:
the last one
Step-by-step explanation:
there is a total of 80 items
34+24+10+11=80
= approx. 12.5% so a is wrong
= approx. 13.75% so b is wrong
there were 24 brownies sold and so c is incorrect
there were 10 cookies sold which does equal so the last one is right
3a^2 is greater
Because 2×4×3=24 + 3×3=9 24+9=33
and 4×4=16 × 3 = 48
The sum of the angles of acute angles in a right triangle is 90°.
Therefore w have the equation:
Calculate m∠A:
<h3>Answer: 67°</h3>
