The discriminant of the function would be negative
Answer: -8j + 3i
Step-by-step explanation:
3i + 8j · (- 0.5) - 4j
3i-8j · 0.5 - 4j
3i-4j-4j
3i-8j
-8j+3i
Hope this helps
Answer:
z = -7
x = 1.6
There is no equation in what you typed on the third lie so it cannot be solved (equal sign is missing)
x = - 132/7
Step-by-step explanation:
For all cases the goal is to isolate the unknown (represented by a letter) on one side of the equal sign by using mathematical operations simultaneously on both sides.
In the first equation, to isolate z we need to subtract 4 from both sides:

In the second equation: in order to isolate x we need to get rid of the factor 4 that is multiplying x, therefore we use the division by 4 on both sides:

The third expression you wrote doesn't contain an equal sign and therefore it s not an equation (cannot be solved)
In the last equation, in order to isolate x we need to divide both sides by 7 and also to multiply both sides by 33:

Answer:
<u>x=-2</u>
Step-by-step explanation:
the while goal of this is to isolate the x on one sideso x= the answer, so
first you would want to take the 3 and subtract it from both sides giving you 2x=-4 and then you would divide the 2 to further isolate the x giving you <u>x=-2.</u>
Answer:
Step-by-step explanation:
We need to create an equation to represent how many air fresheners the teacher can buy.
Teacher has $10 and a $3 discount coupon which would give her an extra $3 to spend. Each air freshener is $3.50.
x = number of air fresheners
($10 + $3) / $3.50 = x can be written as $13/$3.50 = x
We add $10 and $3 because that gives us the total amount she has to spend.
We divide by $3.50 because that is the cost of each air freshener. The result is the number of air fresheners she can buy.
In this case.
$13/$3.50 = x
3.71 = x BUT we can't buy part of an air freshener, so she can purchase 3 air fresheners.
