Help me this math I suck at

x = 1

Step-by-step explanation:

This is the answer because:

1) If x equals 1, then -3 x 1 equals -3

2) -3 - 9 = -12 (this is the answer because whenever there are two of the same signs, - and -, you have to multiply the signs, so - times - is equal to a +, therefore the equation will change into 3+9 which equals 12. Once you have 12, put the sign that the bigger number has. 9 has a minus sign in front of it which makes the +12 turn into -12)

Hope this helps! :D

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
