Day One- 2d (d being Day Two)
Day Two- d
Day Three- 5 miles
So the expression would be:
5 + 2d + d
Now, we add together the like terms.
5 + 3d
Hope this helps!
Answer:
Domain = amount of sugar transported ( in tons )
S E R / S is greater than or equal to 0 and is less than or equal to 40
Range = cost to transport sugar ( in dollars )
C E R / C is greater than or equal to 1500 and is less than or equal to 6700
12 is the correct answer. When you have problems like this just add over the equal sign. So 5 plus 6 plus 1 is 12. 12 minus 6 minus 1 is 5!
Answer:
A
Step-by-step explanation:
Inverse variation means that y is getting smaller as x gets bigger. The only way for that to happen is with negative numbers or x as a divisor.
Answer:
Step-by-step explanation:
The discriminant for a quadratic in standard form is given by the formula:
We have the equation:
Hence, a=7; b=-4; and c=5.
Therefore, our discriminant will be:
Evaluate. Hence, our discriminant is:
Notes:
Since our discriminant is negative, this tells us that the quadratic has no real roots.
