Answer:
a=12
Step-by-step explanation:
if a=6b
and b=2
a=2×6
a=12
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following equation:

So:
, the slope is positive

For the graph, we place the point on the coordinate axis:

We draw the line!
The graphic is attached.
ANswer:
, the slope is positive

Answer:
To get the answer 21 you'd need to place the brackets here -
16+5÷(2-1) = 21
Answer: (2,5)
Step-by-step explanation:
To find the x coordinate of the vertex, you will set x-2=0 and solve for x
x-2=0
+2 +2
x = 2
Now since we know the vertex has an x coordinate of 2 we have to solve for y by plotting in the x value.
y= 1/2(2-2)^2 + 5
y = 0 +5
y =5
(2,5)
Answer:
6
Step-by-step explanation:
We use BODMAS/BIDMAS here.
First, we do 5 × 2, as multiplication comes before subtracting and adding.
5 × 2 = 10
Now we can just add and subtract.
5 - 10 = -5
-5 + 11 = 6
