What is the slope of a line that is perpendicular to the line to the line represented by the equation y=1/3x+4

Mathematics

LekaFEV [45]3 years ago

Answer:

C.

Step-by-step explanation:

Perpendicular slope means it's the opposite, meaning the perpendicular slope of 1/3 is -3 because -3 = -3/1. [note: if it's positive it should come out negative and just the opposite if it's a negative (the fraction should also be flipped)]

The two triangles below are similar. What is the similarity ratio of ΔABC to ΔXYZ?
jek_recluse [69]

we know that

If the ΔABC and ΔXYZ are similar. then the  corresponding sides of the triangles are proportional

\frac{AB}{XY}= \frac{BC}{YZ}= \frac{AC}{XZ}

we have

AC=15\ units\\XZ=10\ units

Find the ratio

\frac{AC}{XZ}

substitute the values

\frac{15}{10}

Simplify Divide by 5 both numerator and denominator

\frac{15}{10}=\frac{3}{2}

therefore

<u>the answer is</u>

\frac{3}{2}

Indicate the answer choice that best completes the statement or answers
zysi [14]

Answer:

Option D. y = 5x + 1

Step-by-step explanation:

From the question given above, the following data were:

Input (x) >>>>>> Output (y)

0 >>>>>>>>>>>> 1

1 >>>>>>>>>>>> 6

2 >>>>>>>>>>>> 11

3 >>>>>>>>>>>> 16

4 >>>>>>>>>>>> 21

To know the the correct answer to the question, we shall apply the equation given in each option to see which will satisfy the table. This can be obtained as follow:

For Option a

y = 3x + 3

x = 0

y = 3(0) + 3

y = 0 + 3

y = 0

y = 3x + 3

x = 1

y = 3(1) + 3

y = 3 + 3

y = 6

For Option b

y = 5x – 4

x = 0

y = 5(0) – 4

y = 0 – 4

y = – 4

y = 5x – 4

x = 1

y = 5(1) – 4

y = 5 – 4

y = 1

For Option c

y = 10x – 9

x = 0

y = 10(0) – 9

y = 0 – 9

y = – 9

y = 10x – 9

x = 1

y = 10(1) – 9

y = 10 – 9

y = 1

For Option d

y = 5x + 1

x = 0

y = 5(0) + 1

y = 0 + 1

y = 1

y = 5x + 1

x = 1

y = 5(1) + 1

y = 5 + 1

y = 6

From the illustrations made above, only option d satisfy the table. Thus, option d gives the correct answer to the question.
