Tomas wrote the equation y = 3x +y equals 3 x plus StartFraction 3 over 4 EndFraction.. When Sandra wrote her equation, they dis

covered that her equation had all the same solutions as Tomas’s equation. Which equation could be Sandra’s?
–6x + y = negative 6 x plus y equals StartFraction 3 over 2 EndFraction.
6x + y = 6 x plus y equals StartFraction 3 over 2 EndFraction.
–6x + 2y = negative 6 x plus 2 y equals StartFraction 3 over 2 EndFraction.
6x + 2y = 6 x plus 2 y equals StartFraction 3 over 2 EndFraction.

Answer:

-6x+2y=\frac{3}{2}

Step-by-step explanation:

The equation Thomas wrote is:

y=3x+\frac{3}{4} ...equation 1

Let us subtract 3x from both sides to get:

-3x+y=\frac{3}{4}

We now multiply through by 2 to get:

-6x+2y=\frac{3}{2} ....equation 2

We can see that equation one and two are equivalent and hence have the same solution.

Therefore Sandra's equation is -6x+2y=\frac{3}{2}

What is the area of the semicircle (use 3.14 for p)?<br> Please help! Will mark brainlyest.
Marizza181 [45]

Answer:

127.17 cm²

Step-by-step explanation:

  • Area of a semicircle: 1/2*π*r²
  • π (pi) = 3.14
  • r (radius) = d (diamater) / 2 => 18/2 = 9 cm

A = 1/2*π*r²

A = 1/2*3.14*9²

A = 1/2*3.14*81

A = 3.14*40.5

A = 127.17 cm²

Therefore, the area of the semicircle is 127.17 cm²

Hope this helps!
