I believe A and B are the ones. As for explaining? hmm. I would honestly say that any number to the right of a number is a tenth of the place above it. But then again, it's optional to explain ;P
Answer:
x: 148 degrees
y: 32 degrees
Step-by-step explanation:
Hello!
To find the unknown values of these angles, we must understand the concept of intersecting lines. When calculating the angles of the intersecting lines, SQP and RQT are identical values since they are on the opposite ends of each other when given these sorts of problems. This helps us find y being 32 degrees.
On the other hand, to find x, we just need to focus on the line PQR. it's a line, which means that it is 180 degrees. Since SQP is 32 degrees, SQR, or the angle that is x, should be 180-32, which is 148
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!
Answer:
Step-by-step explanation:
Mid point of two points is given as
Let Point 1 be(x1,y1)
And point 2 be (x2,y2)
Then, mid point is given as
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
So, given that,
Point 1 =(4,5)
Then, x1=4 and y1=5
Point 2=(1,2)
Also, x2=1 and y2=2
Then, applying the formulae
M = [ (x1+x2) / 2 , (y1+y2) / 2 ]
M = [ (4+1) / 2 , (2+5) / 2 ]
M = [ 5 / 2 , 7 / 2 ]
Then, the midpoint is
M=(5/2, 7/2)
To decimal point
M=(2.5 , 3.5)
To mixed fraction
M=(2½, 3½)
(x, y)=(2½, 3½)
