Answer:
x=0
Step-by-step explanation:
The axis of symmetry: 
when the equation is 
The given equation is:
To make the a and b values more easily identifiable, we can rewrite it like this:
Now, we can tell that a=1 and b=0. Plug these into the equation :
Therefore, the equation for the axis of symmetry for the parabola is x=0.
I hope this helps!
No. 6/8=9/12
by multiplying the denominators you get the common denominator of 72
then multiply each numerator by the number of the opposite denominator
8x12=96
6x12=72
9x8=72
Therefore, 72/96=72/96
(6/8 = 9/12)
Answer:
65º
Step-by-step explanation:
- The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
- The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
- We can solve from there, x+40+3x+10+180-6x=180
- Combine like terms, -2x+230=180
- Subtract 230, -2x=-50
- Divide by -2, x=25
- m∠CAB=(x+40)º=(25+40)º=65º
- m∠ABC=(180-6x)º=(180-150)º=30º
- m∠BCA=(3x+10)º=(75+10)º=85º
Answer:
12 _3/4
Step-by-step explanation:
3/4 + 1/2 + 2 = 3_1/4
16 cups in a gallon
16-3_1/4
=12_3/4
3x+2(5x-3)=7
3x+10x-6=7
13x-6=7
13x=13
x=1
