First term is -7, so a_1 = -7
To get the next term, we add on 4. We can see this if we subtract like so
d = (2nd term) - (1st term) = (-3) - (-7) = -3+7 = 4
So d = 4 is the common difference.
Apply a_1 = -7 and d = 4 to get...
a_n = a_1 + d*(n-1)
a_n = -7 + 4*(n-1)
a_n = -7 + (n-1)*4
Answer: Choice A
The amount of money that Layla has saved, s, is going to be what the equation equals. She earns $150 each month, so that would be 150m (slope intercept form equation s=em+b). B is the y-intercept, or the amount that Layla already has saved, which is positive $650.
Your equation is:
s=150m+650
I hope this helps :)
Answer:
Associative Property
For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4.
Because the design is scaled by 3, the new dimensions are 9*3 X 12*3 = 27 X 36
Since the dimensions are 27 X 36, the area is equal to 27*36 = 972 square inches.
Answer:
C.
If the line doesn't pass through the origin, the easiest point to pick is the origin (0,0). Substitute into your inequality.
y > 5x + 1
0 > 5(0) + 1
0 > 1 which is a false statement.
So, you shade the side of the line on which (0,0) doesn't lie.
If the statement would have be true, you shade the side of the line on which (0,0) lies.
