Answer:

Step-by-step explanation:

The interior angles of a triangle always add up to 180°.

As QE=ED=QD

so, ∠Q=∠E=∠D=180°/3=60°

As, ∠D=5x+20

60=5x+20

5x=40

x=8

Hope, this helps you.

Answer:

x= 8

Step-by-step explanation:

QE=ED=QD

SO;

Sum of angles =180

each angle = 60

5x+20= 60 —> 5x =60-20 —> 5x = 40

x = 40/5 —> x = 8

I hope I helped you^_^

I'm assuming that y2 means y^2 or y squared. In that case, your factors will be (6y+1) and (6y-1).

How do I graph x - 4y < 0

Temka [501]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-4y < 0$

isolate the variable y

$-4y < -x$

Divide by -4 both sides

Remember

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$y > \frac{x}{4}$

The solution of the inequality is the shaded area above the dashed line $y=\frac{x}{4}$

The slope of the dashed line is positive m=1/4

The y-intercept of the dashed line is (0,0)

The x-intercept of the dashed line is (0,0)

using a graphing tool
