To find the perpendicular line a y- 2 = 7/3 (x + 5) you must first observe that the slope is m = 7/3, therefore, the slope of the perpendicular line put of the reciprocal, that is, m = - 3/7. So the possible options are A or C, but since the point (-4, 9) must go through the line, we find that the equation that satisfies that is option C.Therefore the perpendicular line that passes through the point (-4, 9) is C. y - 9 = -3/7 (x + 4)
F(x)=x (and then plus something, i’m not sure)
1) 5 + ( 2 + 7) = (5 + 2) + 7
It is the associative property of the addition.
This property states that when adding 3 numbers, the grouping or association of the numbers does not change the result.
2) <span>The second expression is unreabable

<span>3) h + 0 = h
</span>
<span>It is the identity property.
</span>
This property states that 0 is the identity element of the addition and any number added to it is equal to the same number.
AS you know, 5 + 0 = 5, 1234 + 0 = 1234; 0 + 2548 = 2548.
Answer:
840
Step-by-step explanation:
If two teams play one match and there is 420 matches, you just multiply 420 by 2.
