QR = LN, so
-2x = -3y + 3
OP = VW, so
-6x =-6y + 18
(-2x = -3y + 3)*(-2) ------> 4x = 6y - 6
-6x = - 6y + 18
4x = 6y - 6
<u>-6x = - 6y + 18</u>
-2x = 12
x= - 6
That's a tricky one because x is a function of y but y isn't a function of x.
(x, x²) is a perfectly good relation.
I'm not totally sure but I'd
Answer: B
D is the other answer that may be accepted but knowing teachers, I'd go with B.
Answer: the current value of the house is $343350
Step-by-step explanation:
The initial value of the house on the market was $315,000.
After several years the value increased by 9%. This means that the amount by which the value of the house increased over the years would be
9/100 × 315000 = 0.09 × 315000 = $28350
The current value of the house would be the sum of the previous value of the house and the increase in value. It becomes
315000 + 28350 = $343350
Answer:
(5, 0)
Step-by-step explanation:
The ordered pair located 5 units to the right on the x axis is (5, 0) which indicates the x-location first (x = 5) and the y-location in the second coordinate (y = 0)
Answer:
50 Db
Step-by-step explanation:
we know that
The loudness in decibels is given by the formula
where
I = sound intensity in watts per square meter (Watts/m^2)
I₀ = reference intensity, = 10^(-12) Watts/m^2
so
For I=10^(-7) Watts/m^2
substitute in the formula above and solve for L
