Answer:
Sn=a+(n-1)d
n=60,a=-10,d=8-(-10)=8+10=18
S60=-10+(60-1)18
S60 =-10+(59)18
S60=-10+1062
S60 =1052
(4a+6b)×(a-b)
=4a(a-b)+6b(a-b)
=4a^2-4ab+6ab-6b^2
=4a^2+2ab-6b^2
Answer:
y = - 3x + 4
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 )
Here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (2, - 2) into the partial equation
- 2 = - 6 + c ⇒ c = - 2 + 6 = 4
y = - 3x + 4 ← equation of line
