Check the attached file for the answer.
At every 1.0 unit, boiling point decreases 1.8 unit, which means the slope m = -1.8.
I truly don’t know the answer but i think it is 837 feet
Answer:
B. (x - 6)(x + 2).
Step-by-step explanation:
x^2 - 4x - 12
We need 2 numbers whose product is the last number -12 and whose sum is the coefficient of x (-4).
These numbers are -6 and + 2.
So the factors are (x - 6)(x + 2).
EZ!
Let's say each box costs $X and each program costs $Y
Thus, Mike's family spent:
$(5X+3Y)
or
$41
Sean's family spent
$(3X+2Y)
or
$26
This yields us a system of two equations:
5x+3y=41
3x+2y=26
<span>5x+3y=41
</span>2y=26-3x
<span>5x+3y=41
</span><span>y=13-1.5x
</span>
5x+3(13-1.5x)=41
y=13-1.5x
5x+39-4.5x=41
<span>y=13-1.5x
</span>
0.5x+39=41
<span>y=13-1.5x
</span>
0.5x=2
<span>y=13-1.5x
</span>
x=4
<span>y=13-1.5x
</span>
x=4
<span>y=7
</span>
Each box costs $4 and each program costs $7
