Answer:
105° will be the correct answer
The first one is A,B,and D because for A a function on a graph rises from left to right.B because the input or x is not repeating so just remember that too many x's ain't right but more than one y or output is okay.D because each x is not repeating which is a no no in functions.The second question is the first one is a function and the rest no because the first one none of the x or repeating the other ones their x in their data set is repeating.
Answer:
11.56 m²
Step-by-step explanation:
3.4×3.4=11.56m²
<span>2x+7y=-1 (1)
4x-3y=-19 (2)
multiply equation (1) by 2
4x + 14y = -2 (1')
</span>4x - 3y = -19 (2)
---------------------subtract
17y = 17
y = 1
<span>2x+7y=-1
</span><span>2x+7(1)=-1
</span>2x + 7 = -1
2x = -8
x = -4
answer
(-4, 1)
