A system of equations is shown below. 8x - 2y = -4 4x - y = -2

Mathematics

Dvinal [7]3 years ago
5 0

Answer:

Step-by-step explanation:

Solve this system using elimination by addition and subtraction:

Multiplying the second equation by -2 yields the modified system

8x - 2y = -4

-8x + 2y = +4

Adding these together, we get 0 + 0 = 0  (This is always true.)

There are an infinite number of solutions.

Geometry. I'm really struggling with this.

Answer:

The measure of Angle G is 62.5°.

Step-by-step explanation:

Given:

Δ EFG is an Isosceles Triangle.

EG = EF

m∠ E = 55°

To Find:

m∠ G = ?

Solution:

Δ EFG is an Isosceles Triangle. ........Given

EG = EF                                   ..............Given

∠ G = ∠ F = x (say)              ..................Isosceles triangle property

Now in Δ EFG we have

∠ E + ∠ G + ∠ F = 180° .......... Angle sum property of triangle

On substituting the values we get

55 + x +x =180\\\\2x=180-55\\\\2x=125\\\\\therefore x=\frac{125}{2} =62.5\°\\\\\therefore x=62.5\°

The measure of Angle G is 62.5°.
