<span>sin 90° = 1
</span>
cos 0° = 1
There's a simple formula : <em>sin θ = cos (90°- θ)</em> or <em>cos θ = sin (90°- θ) </em>
So : cos 0° = sin (90° - 0°) = sin 90° = 1
Answer:
4 cups of sugar require 14 cups of sugar
Step-by-step explanation:
Given

Required
Determine the cups of flour for 4 cups of sugar
First, we need to determine the unit rate for 1 cup of sugar.
This is done by multiplying both sides by 4


Next, we determine cup of flour for 4 cups of sugar.
This is done by multiplying both sides by 4



<em>Hence;4 cups of sugar require 14 cups of sugar</em>
slope intercept form is y=mx+b
so solve for y
2x+y=-3
minus 2x both sides
y=-2x-3
-2y=6+4x
divide both sides by -2
y=-3-2x
y=-2x-3
