3(x+4)=7x Solving linear equations

Mathematics
1 answer:
Lilit [14]3 years ago
5 0

Answer:

x = 3

Step-by-step explanation:

To solve this equation, we can use basic algebraic techniques as illustrated.

3(x + 4) = 7x Distribute the 3.

3x + 12 = 7x Subtract 3x from both sides of the equation.

12 = 4x Rearrange the equation so the variables are on the left.

4x = 12 Divide by 4 on both sides of the equation.

x = 3

Graph the hyperbola with equation quantity x minus 1 squared divided by 49 minus the quantity of y plus 3 squared divided by 9 e
Sliva [168]

Answer:

See attached diagram

Step-by-step explanation:

You are given the equation of hyperbola

\dfrac{(x-1)^2}{49}-\dfrac{(y+3)^2}{9}=1

From this equation,

  • the center of hyperbola is at point (1,-3);
  • the real semi-axes a^2=49\Rightarrow a=7;
  • the imaginary semi-axes b^2=9\Rightarrow b=3.

Draw two parallel lines x=1 and y=-3 (they intersect at the center of hyperbola), then on horizontal line match two hyperbola's vertices (7 units to the left and 7 units to the right from the center). Then draw two branches of hyperbola (one in negative direction and one in positive direction).

Surface Area is the area of each face added together. For this question lets find the area of one triangle first.

Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.

Now, lets find the area of the squre. area of square is side*side or side^2.

So we multiply 6*6=36. that is the area of the square.

To find the surface area, we must add Area of Triangles+Area of Square.

so, 84+36=120

So the surface area is 120
