Answer:
B
Step-by-step explanation:
The vertex of the parabola is (-1,-4)
So the axis of symetry is x=-1
Answer:
Well 5 cups.
Step-by-step explanation:
Well you see, you have this right:
2*10=20
in which 2 equals Blue, 10 equals Yellow, and result equals green, so now we have 1 instead of 2, right? So that means 2:2=1, so you got to do this:
2*10=20
(2:2)*(10:2)=1*5=5, So the final answer is 5 cups of yellow cups Now please give me 20 pts
Answer:
(-3/2, 5/2)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
3x + y = -2
5x - y = -10
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Eliminate y</em>
- Add 2 equations together: 8x = -12
- Divide 8 on both sides: x = -12/8
- Simplify fraction: x = -3/2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: 3x + y = -2
- Substitute in <em>x</em>: 3(-3/2) + y = -2
- Multiply: -9/2 + y = -2
- Add 9/2 on both sides: y = 5/2
Answer:
c = 40 degrees ; b = 100 degrees
Step-by-step explanation:
Since this is a isosceles triangle, sides WV and WU are the same length.
c = 40 degrees
There are 180 degrees in a triangle.
180 - 40 - 40 = 100
b = 100 degrees
I hope this helps!
She earns $9/hour. If you add up 2.5 and 4.5, you would get 7. Now you just need to divide. 54/7=9.
