The slope is the change in Y over the change in X
With the given points, the first number inside the parenthesis is the X values and the second number is the Y values.
Slope = (Y2 - Y1) / (x2-x1)
Slope = -5 - 3 / 4 - (-6)
Slope = -8 /10
Slope = -4/5
Answer:
B and C
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
b.
If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.
So tan O = BD/16 = 15/8
BD = (16*15)/8
= 2*15
= 30.
So the area of triangle ABC = 16*30
= 480 cm^2.
Answer:
Step-by-step explanation:
3(x + 5) = 36
3x + 15 = 36
3x + 15 -15 = 36 - 15
3x = 21
3x/3 = 21/3
x = 7
Answer:
31/35
Step-by-step explanation:
The fraction of the money raised by Fiona and Patrick is the sum of the fractions given for the money raised by both of them. Given that Fiona raised 2/7 of the money and Patrick 3/5, the sum of these 2 fractions
= 2/7 + 3/5
make the lowest common multiple of the denominators the base and multiply the numerators by it
= (10 + 21)/35
= 31/35
