Easy peasy
slope=(change in rise)/(change in run)
aka
slope between points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1) since y is rise/up and x is run/leftright
points
(-7,-9) and (-5,-8)
x1=-7
y1=-9
x2=-5
y2=-8
remember minusing a negative means addin a positive
slope=(-8-(-9))/(-5-(-7))=
(-8+9)/(-5+7)=1/2
slope=1/2
positive slopes go from bottom left to top right
since it is less than 1
it is more horizonal than vertical
The x-intercept is when y = 0
y = x - 5 → 0 = x - 5 → x = 5
The y-intercept is when x = 0
y = x - 5 → y = 0 - 5 → y = - 5
Answer: x-intercept is (5, 0), y-intercept is (0, -5)
Tangerine is simply color orange, which is an addition of red and yellow colors. To analyze if the portions written below are reasonable, the given sum must equal to the sum of the individual red and yellow parts.
Total Red + Total Yellow = 5(3/10)
3(9/10) + 2(3/8) ? 5(3/10
3.45 ? 1.5
3.45 ≠ 1.5
<em>Since they are not equal, then it means the portions are unreasonable.</em>
Use the Pythagorean theorem:

c - a hypotenuse
a, b - legs
We have: a = 9 and c = 12. Substitute:

<em>subtract 81 from both sides</em>

A Pythagorean triple consists of three positive integers a, b and c, such that
.
is not positive integer.
<h3>The sides of the triangle do not form a pythagorean triple.</h3>
Answer: C, because I’m assuming you meant 84°.
Explanation: 2+6+7 is equal to 15. The three angles of a triangle will always add up to 180, so you need to divide 180 by 15, which is 12. Then, multiply each number (2, 6, and 7) by 12 to get your answer, which is 24, 72, and 84 :)
