Answer:
7/4 or 7 over 4
Step-by-step explanation:
slope formula: (y2 - y1) / (x2 - x1)
= (6 - (-8)) / (5 - (-3))
= (6 + 8) / (5 + 3)
= 14 / 8
=7 / 4
Multiply both sides by 3
Simplify the numerators
Multiply both sides by 6
Simplify the numerator
Multiply both sides by x
12x - 18 = 15x Subtract 12x from both sides
-18 = 3x Divide both sides by 3
-6 = x Switch the sides to make it easier to read
x = -6
Check your answer by plugging -6 in for the x in the original problem:
Plug in -6 for x
Change
to
so all denominators are the same
Change
to
for easier work
Subtract the numerators (4 - (-1) )
=
So,
x = -6 .
Answer:
-14.4
Step-by-step explanation:
the reason being is because 6 degrees celsius is equivalent to 42.8 degrees 14 degrees celsius is equivalent to 57.2 degrees, that stated subtract subtract 57.2 from 42.8 and get -14.4
Answer:
Total score = 39 points
Step-by-step explanation:
For each correct question, you get 2 points, and there are 22 correct questions, so:
22 * 2 = 44 points.
For each question left blank, you get 0 points, and there are 7 questions left blank, so:
7 * 0 = 0 points
For each incorrect question, you get -1 point, and there are 5 incorrect questions, so:
5 * (-1) = -5 points.
The total number of points is:
Score = 22*2 + 7*0 + 5*(-1) = 44 + 0 - 5 = 39 points
