Answer:

x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

8/4 = (8 +(x -1))/5

10 = x +7 . . . . . . . . . multiply by 5 and simplify

3 = x . . . . . . . . . subtract 7

<em>Alternate solution</em>

The short segments are also proportional:

(x -1)/(5 -4) = 8/4

x -1 = 2 . . . . simplify

x = 3 . . . . . . add 1

On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30

Troyanec [42]

Assume that the dimensions of the room in the plan are a (width ) by b (length),

such that a*b=30.

Since the scale is 1:100, a represents 100a, and b represents 100b.

So the actual dimensions are 100a by 100b.

The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)

Answer: 300,000 (square units)

What is the solution to the equation |x − 4| = 17?

andrey2020 [161]

$~~~~~~|x-4| = 17\\\\\implies x -4 = 17~~~~ \text{or}~~~~~ x -4 = -17\\\\\implies x = 17+4~~~~\text{or}~~~~~ x = -17+4\\\\\implies x = 21~~~~~~~~~\text{or}~~~~~x = -13$

The function f(x) = x2 is transformed to f(x) = −1.4x2. Which statement describes the effect(s) of the transformation on the gra

Romashka-Z-Leto [24]

Answer:

C) The parabola is narrower and reflected across the x-axis.

Step-by-step explanation:

The original parabola has equation:

$f(x) = {x}^{2}$

The transformed parabola has equation

$f(x) = - 1.4 {x}^{2}$

How wide the graph is can be determined by the absolute value of the coefficient.

The smaller the absolute value of the coefficient, the wider the graph.

Since

$|1| \: < \: | - 1.4|$

The original graph is wider than the transformed graph.

Also the negative factor tells us there is a reflection in the x-axis.

Refer to the figure below. If m<60 degrees l, find the measure of the other angles. Show your work(or explain) to receive ful

gladu [14]

All of the angles combined =360 degrees

Vertical angles are congruent, so if angle 1 = 60, so does angle 3

Logically we have to find the measure of angle 4 and angle 2 combined and divide by 2

60 + 60 = 120

360 - 120 = 240

240 / 2 = 120

angle 4 = 120
angle 2= 120

angle 3 = 60
