Answer:

Step-by-step explanation:
Sometimes the quadratic is easier to graph if written in vertex form.
y = -x^2 -6x -3
= -(x^2 +6x) -3
= -(x^2 +6x +9) -3 +9
= -(x +3)^2 +6
This is a parabola that opens downward, with its vertex at (-3, 6). Unlike the one shown in the graph already, its scale factor is 1, so it will appear narrower than the one given with the problem statement.
Answer:
Step-by-step explanation:
Divide all three terms by 2 to isolate x:
|x + 5/2| > 0.25
Case 1: x + 5/2 > 0.25 (no absolute value symbol needed), or x > -2.25
Case 2: -(x + 5/2) > 0.25. Multiplying both sides by -1 yields
x + 5/2 < -0.25. Subtracting 5/2 from both sides: x < 5.45
The solution set is -2.25 < x < 5.45.
It's 139 because you divide 347.5 by 2.5 = 139
Answer:
112 kilometers
Step-by-step explanation:
the reason why is because if you divide 208 by 26 you get 8 then multiply it by 14 to get the answer
Answer:
They will get both get $280 if they work for 20 hrs.
Step-by-step explanation:
1) In order to solve the problem, we can use a system of equations
2)Aaliyah's salary equation: y=13x+20
Finn's salary equation: y=12x+40
3) Using the equal values method, we now know that 12x+40=13x+20
4) when you solve the equation, x=20.
5) Substitute 20 for x.
y=12X20+40
y=280
