Answer:
y= 5x......eqn(1)
-2x+2y= 12......eqn(2)
now
substituting value of eeqn(1) in eqn(2) ,
-2x+2(5x) =12
-2x + 10x = 12
8x = 12
X = 12 ÷ 8
X= 3/2
now put value of X in eqn (1)
y= 5x
y = 5 × 3/2
y = 15/2
Step-by-step explanation:
not sure any ans but I tried my best : )
Move all terms to the left side and setequal to zero. Then set each factorequal to zero. and you should get x=9/a+b
The drop in temperature each hour is 2.528 degrees
<h3>How to determine how much did the temperature drop each hour?</h3>
The given parameters are:
Temperature drop = 15.8 degrees
Time = 6.25 hour
The temperature drop each hour is calculated as
Drop = Temperature drop/Time
So, we have
Drop = 15.8/6.25
Evaluate the quotient
Drop = 2.528
Hence, the drop in temperature each hour is 2.528 degrees

Answer: 5th degree trinomial
The degree is 5 because its the largest exponent of the single variable polynomial.
It's a trinomial because there are 3 terms. The terms are separated by a plus or a minus.
A, E, and F are the answers
