Well, the answer to this question is 55 degrees.
In this whole line intercept, the total number of degrees is 360 degrees and if 55 plus 55 equals to 110, then to solve the missing two angles, we can just subtract 110 from 360 which equals to 250 and lastly, we have to divide 250 by 2 which is 125.

Is the Y value of the vertex of 4x squared plus 8X minus 8. help meee

SIZIF [17.4K]

Answer:

y = -12

Step-by-step explanation:

You first calculate the x coordinate using the equation x = $\frac{-b}{2a}$ , which in this case is $\frac{-8}{8} = -1$ .

Then plug that x value into the equation to get the y coordinate:

4(-1)²+8(-1)-8 = -12

The following table gives the science scores and times spent studying for 10 students:

AveGali [126]

There appears to be a positive correlation between the number of hour spent studydng and the score on the test.

When identifying the independent and dependent quantities, we think about what would cause the other to change. The score on the test would not cause the number of hours spent studying to change; rather, the number of hours spent studying would cause the score to change. This means that the number of hours studying would be the independent quantity and the score would be the dependent quantity.

Plotting the graph with the time studying on the x-axis (independent) and the score on the y-axis (dependent) gives you the graph shown. You can see in the image that there seems to be a positive correlation; the data seem to generally be heading upward.

The midpoint of AB is M(7,-5). If the coordinates of A are (6,-7), what are the coordinates of B?

Virty [35]

Answer:

_____________________

a(6,-7) m(7,-5) letb(p,q)

Now,

Let a(6,-7) be x1 ,y1

Let b(p,q) be x2,y2

x,y = (7,-5)

Using Mid point Formula,

x = x1+x2 y= y1+y2

_____ , _____

2 2

7 = 6+p -5 = -7+q

___ , ____

2 2

or, 7×2=6+p , -5×2= -7+q

or, 14=6+p , -10= -7+q

or, p=14-6 , q= -7+10

p=8 , q= 3

Step-by-step explanation:

So , The coordinate of B(8,3)
