Answer:

The area of triangle K is 16 times greater than the area of triangle J

Step-by-step explanation:

we know that

If Triangle K is a scaled version of Triangle J

then

Triangle K and Triangle J are similar

If two triangles are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

Ak ------> the area of triangle K

Aj -----> the area of triangle J

so

z^{2}=\frac{Ak}{Aj}

we have

z=4

substitute

4^{2}=\frac{Ak}{Aj}

16=\frac{Ak}{Aj}

Ak=16Aj

therefore

The area of triangle K is 16 times greater than the area of triangle J

Please help me ASAP with part A and B
Troyanec [42]

Answer:

Step-by-step explanation:

Area of rectangle is

A = 5(4x) = 20x

Part A

(D) <em>100 ≤ 20x ≤ 1,000</em>

Part B

\frac{100}{20} ≤ \frac{20x}{20} ≤ \frac{1000}{20}

<em>5 ≤ x ≤ 50</em>

Choose the graph below that has an undefined slope.
Ronch [10]

Answer:

The correct option is A.

Step-by-step explanation:

The first line passing through the points (-6,2) and (-6,0).

The slope of a line is

m=\frac{y_2-y_1}{x_2-x_1}

The slope of first line is

m_1=\frac{0-2}{-6-(-6)}=\infty

The second line passing through the points (0,-4) and (-1,1). The slope of second line is

m_2=\frac{1-(-4)}{-1-0}=-5

The third line passing through the points (0,-6) and (2,-6). The slope of third line is

m_3=\frac{-6-(-6)}{2-0}=0

The fourth line passing through the points (0,6) and (-3,-7). The slope of fourth line is


m_4=\frac{-7-6}{-3-0}=\frac{13}{3}

Since the slope of a vertical line is infinity, Therefore option A is correct.

Given the function ƒ(x) = 8(x - 4) - 18, determine the value of x such that ƒ(x) = 22. Select one: A. 3 B. 6 C. 9 D. 12
mojhsa [17]

Answer:

C. 9

Step-by-step explanation:

it's multiple choice so plug each value in

A = -26

B = -34

C = 22

D = 46

so the answer is c

What is the best name for the figure with vertices at the following coordinates? (0,0), (-1, 1), (6, 1), and (2, 0)
algol [13]
We are given with the following vertices:
A (0,0)
B (-1,1)
C(6,1)
D (2.0)

Next is to plot the vertices in the Cartesian plane so that we can identify the figure. See attached image.

The identified shape is a "Parallelogram".

Given that f(x) = x2 – 13x + 36 and g(x) = x – 9, find (f + g)(x) and express the result in standard form.
olga nikolaevna [1]

Answer:

x² - 12x + 27

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= x² - 13x + 36 + x - 9 ← collect like terms

= x² - 12x + 27 ← in standard form
