Answers:

  • Enlargement
  • The new larger rectangle is 16.8 inches by 8.4 inches

==============================================================

Explanation:

I'm assuming 7/5 is the scale factor. If so, notice how 7/5 = 1.4 which is larger than 1.

The scale factor being larger than 1 means we have an enlargement.

The image is going to be larger compared to the preimage.

The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4

The image rectangle is 16.8 inches by 8.4 inches

Answer:

This is an enlargement. The dimensions of the scaled rectangle is 16.8 inches by 8.4 inches.

Step-by-step explanation:

This is a dilation.

A dilation makes a figure larger or smaller.

In this case, the scale factor is an enlargement; the figure will be larger.

The figure will be larger because the scale factor, 7/5, is larger than one (1).

If the scale factor were smaller than one (1), it would be a reduction.

In dilations, a scale factor is how much larger the image will be.

In other words, multiply the side lengths by the scale factor.

The original rectangle has a length of 12 inches and a width of 6 inches.

12*7/5=84/5

6*7/5=42/5

It will be more convenient to change the products, which are fractions, to decimals.

84/5=16.8

42/5=8.4

Therefore, the dimensions of the scale rectangle is 16.8 inches by 8.4 inches.

The coordinates of A, B, and C in the diagram are A (p, 4), B (6, 1 ), and C (9, q). Which equation correctly relates p and q? ↔
aivan3 [116]

Answer:

  D.  p + q = 7

Step-by-step explanation:

The slope of AB is ...

  mAB = (y2 -y1)/(x2 -x1) = (1 -4)/(6 -p) = -3/(6 -p)

The slope of BC is ...

  mBC = (q -1)/(9 -6) = (q -1)/3

We want the product of these slopes to be -1:

  mAB·mBC = -1 = (-3/(6 -p))·((q -1)/3)

  -(q-1)/(6 -p) = -1 . . . . cancel factors of 3

  q -1 = 6 -p . . . . . multiply by -(6 -p)

  q + p = 7 . . . . . matches choice D

Write down a fraction whose value lies between 3 and 4; whose denominator is a multiple of 5; whose numerator is a multiple of 1
slamgirl [31]

Answer:

  33/10 and 55/15

Step-by-step explanation:

Possible denominators that are multiples of 5 less than 17 are 5, 10, 15.

Corresponding numerator ranges are [15, 20], [30, 40], and [45, 60]. In only two of these ranges are there any multiples of 11.

  33 in [30, 40]

  55 in [45, 60]

So, there are only two possible fractions meeting your requirement:

  33/10 and 55/15

What is the result if 3x-9 is evaluated when x = -5?​
Anton [14]

Answer:

Step-by-step explanation:

I wonder if it is the minus that is causing the problem?

Let x = - 5

3*(-5) - 9

-15 - 9

This is a money question. If you are 15 dollars in debt and you spend another 9, where are you? (In the company of the American government. They do this all the time).

- 15 - 9 = - 24
