Answer:
You would multiply the x component by -2
Step-by-step explanation:
(-2) (-2x-5y)=-2(-1)
4x+10y=2
4x+2y=8
set both equal to 4x
4x=2-10y
4x=8-2y
2-10y=8-2y
-6=8y
y=-6/8
y=-3/4
4x + 2(-3/4) = 8
4x=38/4
x=38/16
x=19/8
Only thing I can tell you is to use a corner to a piece of paper. The corner is 90 degrees. It's acute if the corner is bigger than the angle. Obtuse if its smaller.
Step-by-step explanation:
Simplify the expression first by the "flip and multiply" method. We end up first with:
[x(x-3)]/[x⁻¹(x+4)]
Simplifying further we have:
[x²(x-3)]/(x+4)
Solving for restriction we equate the denominator to 0:
x + 4 = 0
x = -4
x≠4 (-4 is a restriction of the expression)
Answer:
$936
Step-by-step explanation:
Simple interest is money you can earn by initially investing some money (a.k.a the principal). In return, a percentage (a.k.a the interest) of the initial money invested is added to the principal, this is what makes your initial investment grow.
The equation for simple interest is:
I = P x r x t
P = Principal, $2600
r = interest rate, 12%
t = time involved, 3 years
Fill in the values:
2600 × 0.12 × 3 = $936.00
