Question 9: Please help, what would be the length of the image of the segment GH?

shepuryov [24]

Answer:

<u><em>The length of the image of the segment GH would be 5 units.</em></u>

Explanation:

You can use the <em>center of dilation</em> as your origin of coordintes.

Thus, the <em>point H</em> would have coordinates (0,0) and the <em>point G</em> (-1,0).

A <em>dilation</em> multiplies the coordinates by the <em>scale factor</em>. Hence:

H = (0,0) → H' = 5 × (0,0) = (0,0)

G = (-1,0) → G] = 5 × (-1, 0) = (-5, 0)

Thus, the length of the image of segment GH would be the distance from 0 to -5 in a number line, which is 5.

Help help help help please business

Margaret [11]

Answer:

x = 35°

Step-by-step explanation:

These are corresponding angles. When a transversal crosses 2 parallel lines, 4 angles are created at each intersection, and each pair of corresponding angles between those are congruent.

These angles are congruent, so you can set them equal to each other:

$2x+20=3x-15$

Then, just solve for x:

$20=x-15\\35=x\\x=35$

You can check that by plugging it back into both:

$2x+20=3x-15\\2(35)+20=3(35)-15\\70+20=105-15\\90=90$

Write a function rule for the area of rectangle whose length is 2ft more than its width. What is the area of the rectangle when

Marianna [84]

According to the problem, the length is 2 feet more than its width, which is expressed as the following function

$l=w+2$

If the width is x, then the length is x+2.

We can express the following function for the area

$A(x)=x(x+2)$

Let's replace the width x = 11 ft.

$A(11)=11\cdot(11+2)=11(13)=143$ <h2>Hence, the area is 143 square feet. </h2><h2>The function for the area is</h2> $A(x)=x(x+2)$

Where x represents the width.
