Write a rule to describe each transformation

Mathematics
1 answer:
Veronika [31]3 years ago
3 0

Answer:

k = 2

Step-by-step explanation:

the dilation k is the scale factor. A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. To find the scale factor k, we will compare the original points with their transformation

Point R is at (-1,2), and R' is at (-2,4).

divide the ys: 4/2 =2

divide the xs: -2/-1 =2

therefore the scale factor is 2

The larger of two numbers is four more than the smaller number.If the sum of the numbers is 61,find the numbers
sergij07 [2.7K]

Answer:

<u>28.5 and 32.5</u>

Step-by-step explanation:

<em>create an equation to solve:</em>

x + (x+4) =61

2x + 4 = 61 combine like terms

2x = 57 subtract 4 from both sides

x = 28.5 divide 2 from both sides

28.5 is the smaller number

the larger number is 4 more so:

28.5 + 4 = 32.5

32.5 is the larger number

check your work:

28.5 + 32.5 = 61

What number is to 100 as 4 is to 78
vitfil [10]
Hello, 

4 is to 78 as x is to 100, we write it as a ratio:

\frac{4}{78}= \frac{x}{100}   \\  \\ x= \frac{100*4}{78}  \\  \\ \boxed{x= \frac{200}{39}=5.13}

Which equation is in standard form?
kifflom [539]
I believe that the last one is true


because the linear equations are

y=ax+b


which means that the point of y-axis is on one side and the slope, point on x-axis and y-intercept are on the other side



good luck
