Gabriela will construct a line parallel to ef through point g.

what step should be her first step?

a. draw a line through point g and point e.

b. with the compass point on g, construct an arc that intersects ef .

c. draw a line through point g intersecting ef.

d. with the compass point on e, construct an arc that intersects ef.

Step-by-step explanation:

We are given a line EF and a point G outside of line EF.

We need to draw a parallel line to EF through a point G outside given line.

In order to draw a parallel line, we need to make an angle though G point with a segment. By using that angle we would be able to draw a parallel line to EF through point G.

In order to make that angle, we need to draw a line through point G intersecting EF.

Therefore, first step would be :

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
