Answer:
y = -2
Step-by-step explanation:
First, we subtract 2y on both sides:
-24 = 12y
Then, we divide 12 on both sides:
y = -2
And we're done ^^ hope this helps!
4, 5 & 6 were answered on another question plus the circle isn't shown on this one.
7. semi circle is half a circle, there re 4 arcs smaller then half
they are DB, DC, AC and AB
last choice is correct
Answer: (x, y) transforms into (-x, y)
Step-by-step explanation:
When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.
So if we do a reflection over the y-axis, then the value of y must be fixed.
So if we start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)
So the rule is, the y value remains equal and the x changes of sign.
Answer:
the value of x = 10°
Step-by-step explanation:
here's the solution :-
we know that, the measure of exterior angle of the triangle is equal to the sum of opposite two interior angles.
so,
=》5x - 7 + 6x + 14 = 14x - 23
=》11x + 7 = 14x - 23
=》7 + 23 = 14x - 11x
=》3x = 30
=》x = 30 ÷ 3
=》x = 10°
to get the equation of any straight line, we simply need two points off of it, let's use the ones in the picture below.
