Answer: x=4 ; y=<u> -4</u>
3
Step-by-step explanation:
2x + y = -4
.(-3)
2x + 3y = 4
-6x-3y=12
<u>2x + 3y = 4</u>
4x=16
x= <u>16</u>
4
x=4
2x + 3y = 4
2.4+3y=4
8+3y=4
3y= -8+4
y=<u> -4</u>

Assume if it is cloudy, then you are outside.
Answer:
5.83 or E
Step-by-step explanation:
Use Pythagorean theorem. 5^2+3^2=c^2 because the diameter is perpendicular it cuts the chord in half.
25+9=c^2
34=c^2
5.83
Answer:
$542
Step-by-step explanation:
we know that
The equation of a exponential decay function is given by

where
y is the value of the lawnmower
x is the time in years
a is the initial value
r is the rate of change
we have

substitute


For x=5 years
