Two equations are given below:a – 3b = 16
a = b – 2

What is the solution to the set of equations in the form (a, b)?


(–2, –6)
(–7, –9)
(–11, –9)
(–12, –10)

Answers

Answer 1
Answer:

Good Morning

a-3b=16

a=b-2

Solve a=b -2 for a

Substitute b-2 for a in a-3b=16

a-3b=16

b-2-3b=16

Simplify both sides of the equation

-2b-2=16

Add 2 to both sides

-2b-2+2=16+2

-2b=18

Divide both sides by -2

-2b/-2 = 18/-2

b= -9

Substitute -9 for b in a=b -2

a=b -2

a=-9-2

Simplify both sides of the equation

a= -11

Answer: (-11,-9)


I hope that's help !

What is the solution for the system? Use the graph below y-x=-3 (line a)
y+x=3 (line b)

A. (0,3)
B. (-3,0)
C. (0,-3)
D. (3,0)

Answers

If you would like to know what is the solution for the system of equations, you can calculate this using the following steps:

y - x = - 3
y + x = 3
_______________
y - x + y + x = - 3 + 3
2y = 0
y = 0

y - x = - 3
0 - x = - 3
x = 3

(x, y) = (3, 0)

The correct result would be D. (3, 0).

In right triangle ABC with the right angle at C, sin A= 2x + .1 and cos B = 4x - .7. Determine and state the vaule of x.

Answers

Imagine \angle A at the top of the triangle and \angle B at the bottom. (or used the attached picture for reference)

\sin A= (opposite)/(hypotenuse)

\cos B = (adjacent)/(hypotenuse)

One thing to note, however, is that the side opposite \angle A is the same side as the one adjacent to \angle B! Thus \sin A=\cos B.

Substitute these values for 2x+0.1 and 4x-0.7 and solve.

 4x-0.7=2x+0.1 \n 4x=2x+0.8 \n 2x=0.8\n \boxed{x=0.4}
