-v+5+6v=1+5v+3 solve for v
earnstyle [38]

Answer: No solution for V.  No solution.

Step-by-step explanation:

-v+5+6v=1+5v+3

Combine like terms together by adding all of the v's together, and number together.

5v+5=4+5v

5v-5v+5=4

0+5=4

5=4

Since this is a false statement, then no solution for V

What is the line of symmetry of the parabola y=x2+6x-9?
Rzqust [24]
First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry

1st: group the number
(X2+6x)-9

2nd: use b/2

6/2 = 3 , 3^2= 9

(X2+6x+9)-9-9

(X2 + 3)-18

Vertex is 3,-18 so the symmetry is 3

Line WX and line YZ intersect at point V. If angle WVY = 4a + 58 and angle XVY = 2b - 18, find the values of a and b so that lin
amid [387]

we know that

If line WX is perpendicular to line YZ

then

see the attached figure to better understand the problem

m∠WVY=90°--------> 4a+58=90-----> 4a=90-58-----> a=32/4------> a=8°

m∠XVY=90°--------> 2b-18=90----> 2b=90+18------> b=118/2-------> b=59°

therefore

<u>the answer is</u>

a) The value of a is 8 degrees

b) The value of b is 59 degrees

The diameter of a circle is 4 in. Find its area in terms of π\pi π.
Serggg [28]

The formula for area of a circle is r² x π.

Since we know the diameter, we can firstly divide by 2 to find our radius.

4/2 = 2

Now that we know the radius, we can substitute it in and square the value.

(2)² x π

(4) x π

Since we're finding the area in terms of pi, we won't multiply by pi, giving us the answer of 4π.

Therefore, the area of the circle is equal to 4π.

<em>Hope this helped! :)</em>
