Answer:
-1/2 or x=2
Step-by-step explanation: The first step you need to do in getting your answer is factoring ,you will factor the left side of the equation first:
(2x+1)(x-2)=0
Next, you will set the factors to equal to "0":
2x+1=0 x-2=0
Then you'll proceed to solve the problem using the basic algebraic equation problem solving steps .When you do this you'll be left with answers of x=-1/2 and x=2
Answer:
1 and 1/4ths a cup to make a batch if i worded that right
First year:
.3 x 2593 = 777.9
$2593 - $777.90 = $1815.10
Second year:
.3 x 1815.10 = 544.53
$1815.10 - $544.53 = $1270.57
Third year:
.3 x 1270.57 = <span>381.171
$1270.57 - $381.171 = $</span>889.39900
$889.39900 rounded to the nearest hundredth is $889.40
Y = 30 - 2(2)
y= 30 - 4
y = 26
We are given

we know that

so, we get
opposite =7
adjacent=24
now, we can find hypotenuse


now, we can draw triangle and then switch vertices accordingly
we can find cos(B) using second triangle

In second triangle:
adjacent=7
hypotenuse =25
so, we get
