I think that is proportional
Answer:
y = -4/5x - 4
Step-by-step explanation:
y - y1 = m(x-x1)
4x + 5y = 20 ( subtract 4x on both sides)
5y = -4x + 20 (divide by 5 on each side)
y = -4/5x + 4
So we know one point is (0,4) y-intercept
now plug in (0,4)
y - 4 = -4/5(x-0) (Distribute -4/5 to x - 0)
y - 4 = -4/5x (now add 4 on each side)
y = -4/5x - 4
Answer:
-1/2
Step-by-step explanation:
Using trigonometry table :
Sine 0 = 0
Cosine 0 = 1
Tangent 0 = 0
Co-secant 0 = 1/sine 0
= 1/0
= undefined
Secant 0 = 1/cos 0
= 1/1
= 1
Cotangent 0 = 1/tan 0
= 1/0
= undefined<span />
Answer:
Step-by-step explanation:
First you will need to change both of the numbers into improper fractions:
56/1 ÷ 7/2
Then do keep change flip. What that means is keep the first fraction the same, change the division symbol into a multiplication symbol, and flip the second fraction:
56/1 x 2/7
Then just multiply the two numerators by each other and the two denominators by each other:
56 x 2 = 112
7 x 1 = 7
112/7 would be the answer.
