Find the next two terms of the following sequence: 14, 38, 74, 122, 182, 254...
Bezzdna [24]
Let's find the difference between each number.
38-14=24
74-38=36
122-74=48
182-122=60
254-182=72
As you can tell, you're adding 12 to each difference before. The next difference would be 72+12=84. Let's add.
254+84=338
Now the next difference would be 84+12=96.
338+96=434
So, the next two terms are 338 and 434.

Some carpet cleaning costs are shown in the table. The relationship is linear. Find and interpret the rate of change
Artemon [7]
Y = m x + b , where m is the slope. The slope is the rise over the run or the change in x ( rooms cleaned ) over the change in y ( cost ).
125 = m * 1 + b
175 = m * 2 + b
-----------------------
b = 125 - m
175 = 2 m + 125 - m
m = 175 - 125
m = 50 ( the rate of change ),  b = 75
The formula is:  y = 50 x + 75
It means that the starting cost will be $75 and that for every room cleaned, the cost will rise for $50.

I need to know how to find this.
GalinKa [24]

Answer:

Angles BCF and EFH

Step-by-step explanation:

When two parallel lines are crossed by another line (the transversal), the angles in matching corners are called corresponding angles. DCF and GFC isn't the correct answer because those would be vertical angles. GFC and BCA would not be corresponding because they do not fall in matching corners. And same with EFH and BCA. Therefore, BCF and EFH would be corresponding.

X °
blondinia [14]

Answer:

86°

Step-by-step explanation:

180° is the sum of all angles in a triangle

The two angles given are 68° and 26°

The equation is : 180° - 68° - 26° = x°

180° - 68° - 26° = 86°

x° = 86°

If my answer is incorrect, pls correct me!
