Answer:
-1/2
Step-by-step explanation:
m=y2-y1/x2-x1
-12-(-4)=(-8)
0-(-16)=16
-8/16
-8/16=(-1/2)
hope this helps :3
if it did pls mark brainliest
Answer:
y-6=4(x+1) or y=4x+10
Step-by-step explanation:
Point: (-1,6)
m=4
Slope-point form is y-y1=m(x-x1)
y1=6
x1=-1
Now, plug it in!
y-6=4(x-(-1)) which is y-6=4(x+1)
Of course, if you want you could always simplify it down to y=4x+10 if you wanted to
Hope this helps!
Step-by-step explanation:
Lets first find the remainder when p(x) is divided by x-2
p(2)=2(2)³+b(2)²+3(2)-5
p(2)=16+4b+6-5
p(2)=4b+17
Now let's find the remainder when q(x) is divided by x-2
q(2)=(2)³+(2)²-4(2)-b
q(2)=8+4-8-b
q(2)=4-b
Now let's equate both of them
4b+17=4-b
4b+b=4-17
5b=-13
b=-13/5 as required
Formula for this case is
(a+b)∧3=a∧3+3a∧2b+3ab∧2+b∧3
(2x+5)∧3=(2x)∧3+3*(2x)∧2*5+3*2x*5∧2+5∧3=8 x∧3+3*4x∧2*5+3*2x*25+125=
=8x∧3+60x∧2+150x+125
Good luck!!!
Answer:
A and C
Step-by-step explanation:
solving the equations
A
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ± 
= ± 2 ← required solution
B
x² = - 4 ← has no real solutions
C
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ± = ± 2 ← required solution
D
2(x - 2)² = 0 , then
x- 2 = 0 ( add 2 to both sides )
x = 2 ← not the required solution
