A is 100 b and d are 80 the whole shape = 360
I use the substitution method, but you can also use elimination and matrix
1. Solve for y in 3x+y=14
y=14-3x
2. Substitute y=14-3x into x+2y=3
-5x+28=3
3. Solve for x in -5x+28=3
x=5
4. Substitute x=5 into y=14-3x
y=-1
5. Therefore,
x=5
y=-1
Have a nice day :D
Answer:
The slope of the parallel lines would be the same but the slope of the perpendicular lines would be the reciprocal
Step-by-step explanation:
To find a reciprocal for 1, 3, 4, 5, and 9 (whole numbers) just put a 1 over the number to make it a fraction and for 2, 6, 7, 8, and 10 (fractions) just flip it.
For example 1 would be 1/10 and 2 would be 3/2
Answer:
Step-by-step explanation:
I don't know what level math you're taking but in lower level math this would be undefined, can't be simplified. But some higher levels simplify it with imaginary or complex number representations. So take your pick, but it's still undefined
Answer:
20 % decay
Step-by-step explanation:
Exponential equations are in the form
y = a * b^x
a is the initial value
b is the growth or decay
b>1 is growth b-1 rate of growth
b <1 decay 1-b rate of decay
1-.8 = .2
Change to decimal form
20 % decay
