Answer:
y+6=-3/4(x-2)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=-3/4(x-2)
y+6=-3/4(x-2)
Answer:
B!
Step-by-step explanation:
A)
75% she knows for sure
Out of the remaining 25%, she has a 1/5 or 20% chance of getting it right. So,
1/4 x 1/5 x 100 = 5%
Total chance of getting a question right:
75 + 5 = 80%
b) If the total is 40, she can expect to get
80% x 40 = 32 questions correct.
Answer:
The solved given equation is
.
Step-by-step explanation:
Given equation is 
To solve the given equation:


Multiply the above equation into
on both sides


To sove the equation by using synthetic division method
2_| 1 1 -16 20
0 2 6 -20
___________
1 3 -10 0
Therefore x-2 is a factor
Therefore the quadratic equation is 
(x-2)(x+5)=0
(x-2)=0 or (x+5)=0

Therefore the factors are x-2,x-2,x+5
Therefore the solved given equation is
