Answer:

The scale factor is 2/3.

Step-by-step explanation:

Given data,

The given image is (6,9)

The image after dilation is (4,6)

The scale factor is calculated by dividing the resultant image by the initial image.

For example, if the initial dimensions are (x1, y1) and the final dimensions are (x2,y2). The scale factor is calculated using x2/x1 = y2/y1 = Scale Factor  

In our scenario,

x1  = 6

x2 = 4

y1  = 9

y2 = 6

Scale Factor = x2/x1

=> 4/6

=> 2/3

Similarly for y axis,

Scale Factor = y2/y1

=> 6/9

=> 2/3

Therefore, the scale factor is 2/3.

Represent each of the following variables in the appropriate letters.Next determine wether the variable has a fixed value or a c
Alex777 [14]

Step-by-step explanation:

a) Let 'm' represents score in a Mathematics test. The variable has a fixed value because the marks Sarah obtained in her test will not change

b) Let 'd' represent the distance between the Zen house and the school. The variable has a fixed value because by using the same route, the distance will always remain constant.

c) Let 't' represent the temperature on the summit of Mount Everest. The variable has a changed value because the temperature may alter depending on the time of day and also climatic conditions which will affect the temperature.

Write an equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4)
MrRa [10]

Answer:

The  equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4) will be:

  • y = 3x-13

Step-by-step explanation:

Given the equation

y + 5 = 3(x - 1)

Writing in the slope-intercept form

y=mx+b

where m is the slope and b is the y-intercept

y = 3(x-1) -5

y  = 3x-3-5

y = 3x - 8

Thus, the slope = m = 3

We know that the parallel lines have equal slopes.

So, the slope of a parallel line is also 3

Using the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

substituting the values m = 3 and the point (3, -4)

y-(-4)=3(x-3)

y+4 = 3x-9

y = 3x-9-4

y = 3x-13

Thus, the  equation for a line that is parallel to y + 5 = 3(x - 1) and goes through the point (3,-4) will be:

  • y = 3x-13

I NEED HELPPPPPP It’s about constant rate I DONT GET THIS AT ALL :’( Explanation needed PLEASEEEEEEEE
Vika [28.1K]

Answer:

D Antenna #4

Step-by-step explanation:

As per given graph we can write the function

  • the intercept is zero, as x=0, y=0
  • at x=2, y=30  ⇒ 30= 2*15
  • at x=4, y=60 ⇒ 60= 4*15

The slope is 15, so the function is

  • y=15x

And the function for the antenna revolving at twice the rate would be

  • y=30x

Comparing data in given tables we can see it is D Antenna #4

  • x= 22 ⇒ y= 22*30= 660
  • x=24 ⇒ y= 24*30= 720

Simplify fully please
neonofarm [45]

Answer:

8x² + 8

Step-by-step explanation:

Given

(x² + 3)² - (x² - 1)² ← expand both factors using FOIL

= x^{4} + 6x² + 9 - (x^{4} - 2x² + 1) ← distribute by - 1

= x^{4} + 6x² + 9 - x^{4} + 2x² - 1 ← collect like terms

= 8x² + 8
