-4x-(-12)=(-11x)+23
+12 +12
-4x=(-11x)+35
+11x +11x
7x=35
/7 /7
x=5
Well its quite simple...
the product of 27 and 13 is 351 (which is found by multiplying 27 and 13)
and the sum of 27 and 13 is 40 (which is found by adding 27 and 13 together)
therefore to work out the difference you have to do:
351 - 40 which equals 311
so 311 is your answer
We have been given an equation
. We are asked to fill in the blanks using our given equation.
The axis of symmetry will be the vertical line passing through vertex.
First of all, we will convert our given equation in standard vertex form of parabola as:
Standard vertex form of parabola:
, where (h,k) is vertex of parabola.

Upon comparing our function with standard vertex form, we can see that vertex of parabola is at
.
The axis of symmetry will be vertical line passing through point
. The vertical line will pass through
, therefore, the axis of symmetry is
.
Since our given parabola is an upward opening parabola, so it has a minimum at
. This means that parabola will intersect the x-axis at two points. Therefore, there are two real solutions for the given function.
Answer:
0.0312
Step-by-step explanation:
You subtract 29.12 by 26 which equals 3.12
Then you divide by 100 which equals 0.0312
