You are fishing at Lake hilton and intend to catch two types of fish: salmon and trout. Local fishing laws allow you to catch at most 10 salmon and at most 8 trout. You intend to capture more salmon than trout. You need to catch at least 5 fish for the family dinner tonight. Let x = the number of salmon and y = the number of trout. Which of the following inequalities are needed to represent this system? Choose all that apply. *
y > x
x ≤ 8
x + y > 5
y ≤ 10
y ≥ 0
x ≤ 10
x > y
x ≥ 0
x + y ≥ 5
y ≤ 8
Answer:
x+y >= 5
y<=8
x<=10
x>y
Step-by-step explanation:
x+y is greater or equal to 5 because you need at least 5 for dinner.
y is less than equal to 8 because the fishing laws state you can't have more than 8 trout.
x is less than equal to 10 because the fishing laws state you can't have more than 10 salmon.
x>y because you intend to catch more salmon than trout
z= -400i - 44.5 what is the real part of z?
Answer:
-44.5
Step-by-step explanation:
The i part is imaginary.
The rest is real.
The real part is -44.5
Answer:
-44.5
Step-by-step explanation:
for a complex number
[tex]z=a+bi[/tex]
a is the real part
so in our case we have
[tex]z=-44.5-400i[/tex]
a = -44.5
so the real part is -44.5
Will give crown thanks!
A: Acute (70<90)
B: Obtuse (140>90)
C: Acute (60<90)
D: Right (90=90)
Acute: x<90
Obtuse: x>90
Right: x=90
simplify and express in a + bi form: (12 + 3i) - (3 - 1)
Answer:
10+3i
Step-by-step explanation:
Subtract 3 and 1 which is 2, Now the equation looks like this:
(12+3i)-(2)
Multiply the negative with 2:
12+3i-2
Subtract 12 and 2:
10+3i
Answer: 10+3i
Hope this helps!

Answer:
C.) This system has infinitely many solutions.
Step-by-step explanation:
y = 2x - 4
2x - y - 4 = 0
2x - y - 4 = 0 can be rewritten as y = 2x - 4 as shown below
2x - y - 4 = 0
-y = -2x + 4
-y/-1 = -2x/-1 + 4/-1
y = 2x - 4
y = 2x - 4 is equal to 2x - y - 4 = 0 because the slope is both 2 and both its y-intercept is -4, these two are coincidence, as they call it, meaning these two lines are the same, so its solutions are anywhere on its line. Shown below in a graph.
(2x2 – 18)(x+3)(2 – 3) = 2x4 – 36x2 + 162
Answer:
X=4
Step-by-step explanation:
I'm took lazy to explain it step by step sorry, but I'm positive that's the correct answer.
Answer:
4
Step-by-step explanation:
(4 - 18)( x+ 3) (-1)= 8 - 72 +162
-14(x+3)(-1) = 98
14(x+3) =98
x+3 = 98÷14
x+3=7
x= 7-3=4

1 - 3x = 3x + 1 solve for x
Answer: x = 0
Step-by-step explanation:
1 - 3x = 3x + 1
then add 3x on both sides
1 = 6x + 1
then subtract 1 on both sides
0 = 6x
then divide by 6 on both sides
0 = x
so x = 0
Answer:
x would be unknown bc there wouldnt be an answer since
1-3x=3x+1
if we take away 1 forom both sides were left with -3x=3x and it would be 6x if we combined them which can be possible bc it would be nothing = 6x if that makes sense
Step-by-step explanation:
9 oranges cost $3.60. How much are 4 oranges?
Answer:
$1.60
Step-by-step explanation:
Set up an equation where you have the total oranges (o) on top and the cost (c) on the bottom. So you will have two fractions equaling each other. So you will have o/c=o/c. Now you just have to replace the variables with what you know. 9 oranges= $3.60, and you want to know how much 4 oranges cost. Since the cost per orange is the same, no matter how many oranges you buy if you divide the amount of oranges by the price you will always get the same number. So replace the variables with the numbers you know and you get,
9/$3.60=4/c
Now to solve an equal fraction problem, simply cross multiply (multiply the two numbers diagonal so 4 and 3.6), and divide (take the multiplied number and divide by the number remaining which will be the number diagonal from the variable) which gives you $1.60 for four oranges.

the mean of 30 numbers is 150.it was detected on rechecking that one value of 165 was wrongly copied as 135.find the correct mean
Answer:
151
Step-by-step explanation:
m=150cm
n=30
new mean =(m*n+165-135)/n
=(150*30+165-135)/30
=(4500+30)/30
=4530/30
=453/3
=151
therefore
correct mean =151

Write equivalent fractions for 2/3 and 3/5 using 15 as the common denominator.
The denominators of two or more fractions must have a common factor, and the calculation can be defined as follows:
Common denominator:The common denominator should be determined if the denominators are different. Creating a commonality that is the product of the two different denominators is by far the most straightforward means of achieving this. To use it, divide each fraction's numerators by the opposing denominator.[tex]\to[/tex] [tex]\frac{2}{3} - \frac{3}{5}\\\\[/tex]
[tex]\to[/tex] [tex]\frac{10-9}{15}\\\\[/tex]
[tex]\to[/tex] [tex]\frac{10}{15} - \frac{9}{15}\\\\[/tex]
So, the common denominator value by using the 15 is equal to
[tex]\to \frac{2}{3} : \frac{10}{15} : \frac{3}{5}: \frac{9}{15}[/tex]

What is 8b - ab + 7a subtracted from 3a - 9ab + b?
Answer:
10a-10ab-7b
Step-by-step explanation:
i dont feel like putting the steps but ik this is correct
The answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have two expressions:
8b - ab + 7a and 3a - 9ab + b
After subtracting:
= (3a - 9ab + b) - (8b - ab + 7a)
= -4a -8ab -7b
Thus, the answer is -4a -8ab -7b after subtracting 8b - ab + 7a from 3a - 9ab + b.
