1. Find the next four terms in the following arithmetic sequence: -3, -6, -9, -12,

Step-by-step explanation:

d=-6+3=-9+6=-12+9=-3

   a(n) = a +(n-1)d

   a(n) = -3+(n-1)-3

The next three terms:

a(5) = -3+(5-1)-3=-15

a(6) = -3+(6-1)-3=-18

a(7) = -3+(7-1)-3=-21

a(8) = -3+(8-1)-3=-24

hope this helps

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

hope i .

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
