Answer:

x = 6

Step-by-step explanation:

Tangent - Secant Power Theorem: 18^2 = 12(21 + x)

324 = 252 + 12x

72 = 12x

x = 6

Answer:

x=6

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(12+x+9)*12 = 18^2

(21+x)12 =324

Divide each side by 12

(21+x) 12/12 = 324/12

21+x = 27

Subtract 21 from each side

21+x-21 =27-21

x=6

Step-by-step explanation:

Chris attempted a total of 25 shots

He made 18 shots

Number of shots missed= 25-18

= 7

Therefore the ratio of shots missed and shots made can be calculated as follows

How many 4 card hands that contain exactly 3 aces and 1 queen can be chosen from a 52 card deck?
sesenic [268]
There are 16 possible hands.

Choosing 3 aces from 4 possible is expressed by:
_4C_3=\frac{4!}{3!1!} = 4

Choosing 1 queen from 4 possible is expressed by:
_4C_1=\frac{4!}{1!3!}=4

This gives us 4*4 = 16 possible hands.

Graph ​24x+25=−6y+7​ . please help :)
Agata [3.3K]

Answer:

Given the equation,  −6y + 7= ​24x + 25, you'll have to transform this equation into its slope-intercept form, y = mx + b:

−6y + 7 = 24x + 25

Subtract 7 from both sides:

−6y + 7 − 7 = 24x + 25 − 7

−6y = 24x + 18

Divide both sides by −6:

\frac{-6y}{-6} = \frac{24x + 18}{-6}

y = -4x - 3 ← This is the <u>slope-intercept form</u>, where m = slope and b = y-intercept.

Next, you need to find at least two points to plot on your graph. We can do this by using the y-intercept, (0, -3). Using the slope, -4 and the y-intercept (0, -3):

Start at (0, -3) then go 4 units down (because it is a negative slope) and 1 unit to the right. Your next point should be (1, -7). You can connect those two points and create a line.    

The attached screenshot shows the graph of the linear equation, y = -4x - 3.
