Answer:
y=5/4x-5
Step-by-step explanation:
y-y1=m(x-x1)
y-0=5/4(x-4)
y=5/4(x-4)
y=5/4x-20/4
y=5/4x-5
c/7 = 6 1/7 ⇒ c = 43 ⇒ 43/7 = 6 1/7
Convert mixed fraction into a simple fraction
6 1/7 ⇒ (6 * 7 + 1)/7 = 43/7
c/7 = 43/7
proportionality:
a/b = c/d where cross products are equal : ad = bc
a = c
b = 7
c = 43
d = 7
<span>ad = bc ⇒ c7 = 7*43 ⇒ c7 = 301 ⇒ 7c/7 = 301/7 ⇒ c = 43</span>
So 4 to the power of 5 would be 1024
and 4 to the power of 3 would be 64
1024 divided by 64 equals 16
The answer would round to 900<span />
Answer:
57 is 0.3% of 19000
Step-by-step explanation:
57 = 0.3x (rewrite it into an equation!)
57/0.003 = x (solve)
x = 19000
tadah!
