Answer:

x = 5 cm

Step-by-step explanation:

We can use proportions of similar triangles.  Put the side of the small triangle over the same side of the large triangle

x                 4

---------- = -----------

40                  32

Using cross products

32x = 4*40

32x = 160

Divide by 32

32x/32 = 160/32

x=5

The table shows the number of subscribers to several Internet providers. Determine if each statement is true or false.
WITCHER [35]

Answer:

A - True

B - False

Step-by-step explanation:

Looking at option A,

Company B had 3.12 subscribers and earned 119. To find each subscriber's value we divide 119 by 3.12

119/3.12 = 38.14

Looking at Option B,

Company A had 2.45 subscribers and earned 108. To find each subscriber's value, we divide 108 by 2.45

108/2.45 = 44.08

Hence, for Option A, each subscriber paid about $40 is correct because it's close to 38.14

For Option B, each subscriber paid about 30 is incorrect since it's way over, 44.08.

Thus,

A - True

B - False

egoroff_w [7]
Y int at (0,4).....thru points (4,1)
slope = (1 - 4) / (4 - 0) = -3/4
initial value 4, slope(rate of change) is -3/4 <==
=======================
y = 22,000x + 40,000
=======================
y = 12x + 48
slope(rate of change) = 12
=======================
(1,10)(2,8)
slope = (8-10) / (2-1) = -2/1 = -2

y = mx + b
8 = -2(2) + b
8 = -4 + b
8 + 4 = b
12 = b

slope(rate of change) = -2
initial value = 12
I am not getting any of ur answer choices ...
