Answer: x+y=23, 3x+2y = 55 x + y = 55, 3x + 2y = 55 x+y=23, 2x+3y= 55 x+y=55, 2x+3y =23
Step-by-step explanation: The question said the sum is x+y so if the sum is 55, x+y=55
Answer:
Step-by-step explanation:
A
Answer:
346
Step-by-step explanation:
Approximately rounded using the decimals this number would be 346 because the 8 behind the decimal point promotes the 9 to make 345.989554676 a whole number. 346. Hope this helps! :)
For something to be a function there can only be one x value for every y value (meaning x can’t repeat). To see if the graphs are functions you need to perform the vertical line test. This is where you scan an imaginary line across the graph and if the line passes through two points at the same time, that graph is not a function. This would mean that for the graphs, only graph B is a function. For the mapping part, if an x value has more than two lines attached to it, it’s not a function. This means that mapping A is a function because it only had one line for every x value whereas mapping B had x value 5 with two lines instead of one. For the table, it’s a function if the x value isn’t repeated. This means that table B is a function because no x value repeats whereas in table A the x value 2 repeats twice. That leaves graph A, mapping B, and table A as ‘not a function’. Hope this helped.
The length of RP is 4 m.
Since a kite is symmetric about one of its diagonals, then the other diagonal bisects that one. Additionally, the diagonals are perpendicular to each other. This forms two right triangles inside of the kite.
The bottom leg of the right triangle will be 3 (half of the diagonal) and the hypotenuse will be 5. We will use the Pythagorean theorem to answer this:
3²+b²=5²
9+b²=25
Subtract 9 from both sides:
9+b²-9=25-9
b²=16
Take the square root of both sides:
√(b²) = √16
b=4
