Answer:
To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function!
Step-by-step explanation:
Answer: A
I'd have to say a because it's the closest answer or best estimate.
Answer:
15 cm
Step-by-step explanation:
Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
.
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
Answer:
x=26
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
(2x-5)° +(4x-1)° + 30° = 180
Combine like terms
6x +24 =180
Subtract 24 from each side
6x+24-24 =180-24
6x = 156
Divide by 6
6x/6 =156/6
x =26
