Answer:

<u>x = 6</u>

Step-by-step explanation:

Applying Geometric Mean Theorem :

  • AD = √CD × DB
  • x = √9 × 4
  • x = √36
  • <u>x = 6</u>

Item 1 A discounted concert ticket costs $14.50 less than the original price p . You pay $53 for a discounted ticket. Write an e
VLD [36.1K]

Answer:

$53 + $14.50 = x

x = $67.50

Step-by-step explanation:

Let us assume the original price be x

It is given that

The discounted ticket is $53

And, the discounted concert ticket cost is $14.50 lower than the orginial price

So, the equation is

$53 + $14.50 = x

Now the x is

= $53 + $14.50

= $67.50

Hence, x denotes the original price of the ticket

We simply added the above two amounts

Draw the graph of the line that is parallel to y−3=1/3(x+2) and goes through the point (1,7).
horrorfan [7]

Answer:

Step-by-step explanation:

First find the slope of the given line.

y - 3 = 1/3(x+2)

y - 3 = (1/3)x + 2/3

y = (1/3)x + 2/3 + 3

y = (1/3)x + 11/3

Compare it with

y = mx + c

We get m = 1/3

As the parallel lines have same slope, the slope of the second line will also be m= 1/3

y = mx + c

y = (1/3)x + c

As this line goes through the point (1,7), substitute it in the equation:

7 = (1/3)1 + c

7 = 1/3 + c

c = 7 - 1/3

c = 21-1/3

c = 20/3

The equation of the line is found by substituting m = 1/3 and c = 20/3 into the general equation

y = mx + c

y = (1/3)x + 20/3

Graph of the equation is shown

Rotate RST 90° counterclockwise around the origin.<br>​
Nostrana [21]

The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

<h3>
How to rotate the triangle?</h3>

The coordinates of RST are given as:

R = (5,15)

S = (15,15)

T = (10,5)

The rule of 90° counterclockwise around the origin is:

(x,y) -> (-y,x)

So, we have:

R' = (-15,5)

S' = (-15,15)

T' = (-5,10)

Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
