I rounded it to 150.
You could round 15.217 down to 15 and 9.54 up to 10 and then multiply 15 x 10 = 150. But you could also multiply 15.217 x 9.54 to get 145.17018 and round that up to 150 because any number that ends with 5 or higher rounds up.
Answer:
A. If none of the output values are repeated, the relation is a function
Step-by-step explanation:
The reason why A is correct stems from the concept of the vertical line test. If each x-value has their own respective output (y-value), then the relation is a function.
Choice B just states that if none of the x-values are repeated. then the relation is a function. This is not correct because it doesnt follow the vertical line test, which analyzes if any y-values are being repeated
Choice C and D doesnt have any correlation with the vertical line test because an x-value doesnt have to equal a y-value to make the relation a function. Vice versa for any y value being equal to any x-value.
Answer:
x = 75
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: -4
Step-by-step explanation:
3-2(0-4)
Do the parenthesis first
( 0 - 4 )
( -4 )
Then solve the other equation
3 - 2 = 1
put them back in order
1(-4)
Now solve for that and you have your answer
-4
