Answer:

One solution. (C)

Step-by-step explanation:

Use substitution to solve the problem:

Since we know y is basically 3 less than x, we can plug that into the second equation.

4x-10(x-3)=6

After solving this we get:

x=4. We can plug this into the first equation.

y=4-3

y=1

There is only one solution.

In this circle, the area of sector COD is 50.24 square units. The radius of the circle is units , and units.

Let angle be alpha

$\\ \rm\Rrightarrow Area=50.24$

$\\ \rm\Rrightarrow \dfrac{\alpha}{360}\pi r^2=50.24$

$\\ \rm\Rrightarrow \alpha 3.14r^2=18086.4$

$\\ \rm\Rrightarrow \alpha r^2=5760$

$\\ \rm\Rrightarrow r^2=\dfrac{5760}{\alpha}$

$\\ \rm\Rrightarrow r=\sqrt{\dfrac{5760}{\alpha}}$

If you have angle measure in degree put in place of Alpha and get the value elaw this is our final answer

Find the value of p for which the given pair of linear equations have infinitely many solutions for 4X + 3 Y - 4 is equals to ze

tino4ka555 [31]

Answer:

x=8/3

y= -20/9

Step-by-step explanation:

4X + 3Y -4 =0

Linear egquations must in

$x + y = 0$

so 4X + 3Y =4

THEN

3X + 9Y = - 12

next use calculator to solve it or you can use traditional way

Find the value of x. Round your answer to the nearest tenth

Sati [7]

$x=13.8$

Step-by-step explanation:

Since the triangle is right use the tangent ratio to solve for x

$tan41^o=\frac{opposite}{adjacent}=\frac{12}{x}$

Multiply both sides by $x$

x × $tan41^o=12$ ( divide both sides by $tan41^o$ )

x = ≈ ( nearest tenth )
