Answer:
its only 5 points tho :c
Step-by-step explanation:
Answer:
B, x=3 y=5
Step-by-step explanation:
x=-7+2y
3y+2x=21
Substitute the x into the other equation
3y+2(-7+2y)=21
y=5
Now put the value into a desired equation
x=-7+2(5)
x=3.
The answer is x=3 and y=5
I hope this helped!
Answer:
In a pair of similar triangles, the corresponding sides are proportional.
Step-by-step explanation:
Corresponding sides touch the same two angle pairs. When the sides are corresponding it means to go from one triangle to another you can multiply each side by the same number.
7 x 5 = 35
35 x 12 =420
Answer:420
Answer:
(3, 4)
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).
Such that a function can map each element of the domain into only one element of the range.
Then, if a "function" has:
f(x1) = y1
and
f(x1) = y2
It is mapping the input "x1" into two different outputs, then this is not a function.
Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)
(The first value is the input and the second one is the output)
Then the point that does not belong to the graph, is the point that has the same input and different output.
(3, 4)
Any of the other points could belong to the graph.
