Answer:
y= -7
Step-by-step explanation:
So first distribute the 8
4=8y+32-4y
now combine like terms (the -4y+8y)
4=32+4y
Subtract 32 on both sides to isolate 4y
-28=4y
now divide 4 on both sides to isolate Y
-7=y
so y= -7
Answer:
Line BD is Congruent to Line BD due to the Reflexive property. Angle Bad is congruent to angle BCD because of the third angle theorem therefore triangle ABD is congruent to triangle CBD because all angles and sides are congruent
I don't know if that will satisfy your teacher because some prefer different things but that leaves no ground to be inferred and explains everything word for word.
1) We are given points on the line of the graph (0,3) and (1,1).
Rise/run represents the slope of the line.
Rise/run = -2/1 = -2.
Therefore, slope of the line is -2.
<h3>Correct option is A) -2 .</h3>
2) Given equation y=7.5x-5.
From the graph we can see that line crosses x-axis at 0.667.
But we don't find any such option.
But we can see line crossing y-axis is -5.
It seems that we need to find the point where line cut y-axis.
<h3>Therefore, correct option is C option.</h3><h3>C) - 5</h3>
A circle with center
and radius
has equation

If we substitute
in this equation, we have

This equation has two solutions (i.e. the line intersects the circle in two points) if and only if the determinant is greater than zero:

The expression simplifies to

The solutions to the associated equation are

So, the parabola is negative between the two solutions:
