Solve this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7

ratelena [41]

Answer:

Solving this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 we get x=2 and y=-3

Solution set = {2,-3}

Step-by-step explanation:

We need to solve this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7

let:

$3x-2y=12--eq(1)\\x+3y=-7 --eq(2)$

Finding value of x from equation 2 and putting in eq(1)

$From \ eq(2)\\x+3y=-7\\x=-7-3y$

Putting value of x in eq(1)

$3x-2y=12\\Put \ x=-7-3y\\3(-7-3y)-2y=12\\Solving\\-21-9y-2y=12\\-11y=12+21\\-11y=33\\y=\frac{33}{-11}\\y=-3$

So, we get y=-3

Now put value of y in equation 2 to find value of x

$x+3y=-7\\x+3(-3)=-7\\x-9=-7\\x=-7+9\\x=2$

So, we get value of x =2

So, solving this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 we get x=2 and y=-3

Solution set = {2,-3}

All the answers please on paper and work

REY [17]

1)
8² + 15² = 17²
64 + 225 = 289
This is true, so the triangle is a right triangle.

2)
4² + 12² = 13²
16 + 144 = 169
This is false, so the triangle is not a right triangle.

3)
20² + 21² = 27²
400 + 441 = 729
This is false, so the triangle is not a right triangle.

4)
28² + 45² = 53²
784 + 2,025 = 2,809
This is true, so the triangle is a right triangle.

PLS HELP QUICK, I HAVE A TEST, more points

bezimeni [28]

Answer:

Options (1), (3), (5) and (6)

Step-by-step explanation:

Option (1)

Both the circles M and H are same in shape. Therefore, both are similar.

True

Option (2)

MH = MS = [Radii of a circle]

MH = MO + OH

MH = ME + OH [Since, MO = ME]

MH = 10 + 25 = 35 cm

Area of circle M = πr²

= π(35)²

= 1225π

Area of circle H = π(25)²

= 625π

$\frac{\text{Area of M}}{\text{Area of H}}=\frac{1225\pi }{625\pi }$

Area of M = 1.96(Area of H)

False

Option 3

OH + MS = 25 + 35

= 60 cm

True

Option 4

m∠HMS = 90°

Can't be figured out with the given informations

False

Option 5

Diameter of circle H = 2(radius)

= 2(25)

= 50 cm

True

Option 6

Circumference of circle S = 2πr

= 2π(ES)

Circumference of circle M = 2π(MS)

Ratio of the circumference of circle S and M = $\frac{2\pi (ES)}{2\pi (MS)}$

= $\frac{ES}{MS}$

True.

Options (1), (3), (5) and (6) are correct.
