You would multiply 20 and 35% or 0.35 since there are 20 players on the team and 35% of them play the guard position. This would equal 7 and thus your answer would be 7 players.

Guard=35% of all
all=20

percent means parts out of 100
35%=35/100=7/20
'of' means multiply

guard=35% of all
guard=7/20 times 20
guard=140/20
guard=7
there are 7 that play guard

What is the equation of the directrix of the parabola given by the equation (y − 3)2 = 8(x − 5)?

Licemer1 [7]

The vertex of the parabola is at (5,3) and its focal length is 8/4 = 2.
Since it opens to the right, the directrix will be a vertical line 2 units to the left of the vertex, so its equation will be x=(5-2), or x=3

The midpoint of AB is M(1, -4). If the coordinates of A are (-3,-6), what are the coordinates of B?

kramer

Answer:

The coordinates of B is (5,-2)

Step-by-step explanation:

In order to find the coordinates of B, you have to use midpoint formula. Then substitute the following values into the formula :

$m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Let (x1,y1) be A (-3,-6),

Let (x2,y2) be B,

Let midpoint be M (1,-4),

$(1, - 4) = (\frac{ - 3 + x2}{2} , \frac{ - 6 + y2}{2} )$

$by \: comparison, \:$

$\frac{ - 3 + x2}{2} = 1$

$- 3 + x2 = 2$

$x2 = 5$

$\frac{ - 6 + y2}{2} = - 4$

$- 6 + y2 = - 8$

$y2 = - 2$

I’ll fail if I don’t get this right pls help

son4ous [18]

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

$3(x - 2) + 7x = \frac{1}{2} (6x - 2)$

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

$3x - 6 + 7x = 3x - 1$

Now, we would shift all x terms to the left and all number terms to the right.

$3x + 7x - 3x = - 1 + 6$

After simplifying, the final equation would be:

$7x = 5$

This is a linear equation and it has one solution.

$x = \frac{5}{7}$

What is the value of x in the equation 8x – 2y = 48, when y = 4?

luda_lava [24]

Answer:

Step-by-step explanation:

8x-2y=48, replace y with 4, 8x-2(4)=48, multiply, 8x-8=48, add 8 to both sides to remove the -8, 8x=56 and finally divide by 8 to remove 8 from x, x=7.
