Solve the following simultaneous equations: 1. a) x-y=-5 and x + y = -1

Sonbull [250]

Answer:

x = -3, y = 2

Step-by-step explanation:

x - y = -5

x = -5 + y

Let's put this into the other equation

(-5 + y) + y = -1

-5 + 2y = -1

2y = 4

y = 2

Now we can solve for x by plugging y into either equation

x + (2) = -1

x = -3

7. Isosceles triangle ABC is shown below with legs that measure 8 inches and a vertex angle of 50D. (a) Determine the area of AB

Flura [38]

Answer:

<h2>The area of the triangle ABC is 32 square inches.</h2>

Step-by-step explanation:

We know that the given triangle is a right-isosceles triangle, which means its leg are equal.

The area of a triangle is defined as

$A=\frac{1}{2}bh$

Where $b=8$ and $h=8$ . Replacing values, we have

$A=\frac{1}{2} \times 8 \times 8 = 32 \ in^{2}$

Therefore, the area of the triangle ABC is 32 square inches.
