Answer:
11/5 slope
Step-by-step explanation:
5-(-6) -4-(-9)
11/ 5
Answer: (x−2)(x−2)
The middle number is -4 and the last number is 4.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -4
Multiply together to get 4
Can you think of the two numbers?
Try -2 and -2:
-2+-2 = -4
-2*-2 = 4
Fill in the blanks in
(x+_)(x+_)
with -2 and -2 to get...
(x-2)(x-2)
Answer:
(x−2)(x−2)
so the answer is D.
Answer:
a) The system that models the situation is:
p + 0.2m = 3
p + m = 5
b) The solution of the system is:
m = 2.5
p = 2.5
Step-by-step explanat:
It is desired to obtain 5 pounds of a mixture containing 40% peanuts and 60% almonds.
It has a mixture of 20% peanuts and 80% almonds.
p: number of pounds of peanuts
m = amount of mixture
The equation that represents the amount of peanut and mixture that is needed is:
p + m = 5 pounds
m = 5-p (i)
The amount of peanut in total that the mixture should have is:
p + 0.2m = 0.6 (5)
p + 0.2m = 3 (ii)
a) The system that models the situation is:
p + 0.2m = 3
p + m = 5
Now we substitute (i) in (ii) and clear p.
p + 0.2 (5-p) = 3
p-0.2p = 2
p = 2.5 pounds
Now we find m
m = 5 - 2.5
m = 2.5 pounds
b) The solution of the system is:
m = 2.5
p = 2.5
Answer:
x = -3h
x = -12
Step-by-step explanation:
Given equation is 
To find the value of x in terms of h we will solve the expression to isolate x on one side of the equation.
by subtracting 1 from both the sides of the equation,
Multiplying 'h' on both the sides of the equation,
x = -3h
If h = 4,
x = (-3)(4)
x = -12
Answer:
no solution
Step-by-step explanation:
Given
- v + 5 + 6v = 1 + 5v ← combine like terms on left side
5v + 5 = 1 + 5v ( subtract 5 from both sides )
5v = - 4 + 5v ( subtract 5v from both sides )
0 = - 4 ← not possible
Hence the equation has no solution
