Help Draw The Line Of Reflection That Reflects \triangle ABCABCtriangle, A, B, C Onto \triangle A'B'C'A

Answers

Answer 1

Answer:

x = 1

Step-by-step explanation:

As we see this is a horizontal reflection.

The reflection line is equidistant from the corresponding vertexes and is the vertical line.

We can find the line by finding the midpoints of AA', BB' or CC'

0 + 1/2(2 - 0) = 0 + 1 = 1-1 + 1/2(3 - (-1)) = -1 + 2 = 1-4 + 1/2(6 - (-4)) = -4 + 5 = 1

The line of reflection is x = 1

3 * 3 = 9, that alone is bigger than 7.

3 * 3 + 1 = 10.

10 is bigger than 7.

Answer:

No

Step-by-step explanation:

To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.

[tex](3)^{2} +1=7[/tex]

9 + 1 = 7

[tex]10\neq 7[/tex]

Therefore, (3, 7) is not a solution.

John needs a plumber to repair the kitchen drain. The plumber charges $85 for the parts that he will need for the repair plus $30 for each hour worked. The maximum amount of money john can spend is $250. Which inequality would represent this situation if x is the number of hours worked?

Answers

Answer:

[tex]30x+85y\leq 250[/tex]

Step-by-step explanation:

Cost of each part is [tex]\$85[/tex]

Cost of working one hour is [tex]\$30[/tex]

Let number of hours worked be [tex]x[/tex] and

number of parts bought be [tex]y[/tex].

The maximum amount of money that John can spend is [tex]\$250[/tex].

From the question we have

[tex]30x+85y\leq 250[/tex]

The required inequality is [tex]30x+85y\leq 250[/tex].

A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.​

Answers

Answer:

P = 60

Step-by-step explanation:

First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.

25       5

----  =  ----

15        3

So the larger triangle is 5/3 times bigger.

This means that all of its other sides with also be 5/3 times bigger.

So:

9 (5/3) = 45/3 = 15

12 (5/3) = 60/3 = 20

25 + 15 + 20 = 60

So the perimeter is 60.

You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:

36 (5/3) = 180/3 = 60

You would get the same thing.

To find:

The value of [tex]f(x+h)[/tex] in simplified form.

Solution:

We have,

[tex]f(x)=x^2+2x+1[/tex]

Putting [tex]x=x+h[/tex], we get

[tex]f(x+h)=(x+h)^2+2(x+h)+1[/tex]

[tex]f(x+h)=x^2+2xh+h^2+2x+2h+1[/tex]

[tex]f(x+h)=x^2+h^2+2xh+2x+2h+1[/tex]

Therefore, the simplified value of [tex]f(x+h)[/tex] is [tex]x^2+h^2+2xh+2x+2h+1[/tex].
