Answer:
Two noncongruent triangles, each with side 6 cm and an angle measuring 40 degrees This might be it
Step-by-step explanation:
Answer:
y = -2x
Step-by-step explanation:
Find the slope and y-intercept to write an equation in the form y = mx + b
Slope = - 20/10 so -2, m = -2 since the line goes down to the right
Then it crosses the y-axis at (0,0) so b = 0 [which is the y value]
Put it all together y = -2x + 0 so y = -2x
Answer:
b= the square root of 20
Step-by-step explanation:
if a^2+b^2=c^2, then c^2-a^2=b^2. 6^2-4^2=c^2. So 36-16=b^2. 36-16=20.20=b^2, then take the square root of both sides to get b= the square root of 20.
Answer:
Yes, there is a proportional relationship:
D = 0.15 × O
Step-by-step explanation:
O = original price
D = discounted price
85% off means the price is 15% of the original
D = 0.15 × O
