Step-by-step explanation:
if x=1 , y =3
if x=4 then y=3×4=12
y=12
<u>Answer:</u>
- 80 km is 9% of 888.89 km.
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
- 80/9 km = 1%
- => 80/9 x 100 = 100%
- => 8000/9 = 100%
- => 888.89 km = 100% (Rounded to nearest hundredth)
Hence, <u>80 km is 9% of 888.89 km.</u>
Hoped this helped.

Answer:
y =
x + 
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
m =
=
, hence
y =
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (1, 5 ), then
5 =
+ c ⇒ c = 5 -
= 
y =
x +
← in slope-intercept form
Answer: -6
Step-by-step explanation:
9% = .09
.09-6.375 = −6.285
6.285 = 6.285/1 = 62.85/10 = 628.5/100 = 6285/1000
GCF = 5, 1257/200 = 6
-6
-6.285 = -6
