Hi,
A is an arithmetic sequence
U(n)=U(n-1)+3
24 because she already completed four and if she completes twelve more that that will be 24 hope that helps
Answer:
64
Step-by-step explanation:
4^3 is the same as 4x4x4
4x4 = 16
16x4=64
so 4^3 is 64
180 = 2x + 26
-26 -26
154 = 2x
÷2 ÷2
77 = x
One of the sides is 77
Answer:
y =
x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = - 3x + 13 is in this form
with m = - 3
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
y =
x + c ← is the partial equation
To find c substitute (6, 10) into the partial equation
10 = 2 + c ⇒ c = 10 - 2 = 8
y =
x + 8 ← equation of line
