f(x) = 4/5 x - 2
Find f(3)
Answer is a fraction
Answer:
2/5
Step-by-step explanation:
f(x) = 4/5 x - 2
Let x=3
f(3) = 4/5 *3 - 2
=12/5 -2
=12/5 -10/5
= 2/5
grandpa has some cows and ducks in his farm. all in all there are 8 heads and 26 legs, how many cows and ducks are in there? solve this using factoring, finding multiples and divisibility rules
Answer:
5 cows and 3 ducks
okay well there are 8 heads and each animal has a head meaning that there are a total of 8 organisms in total. Cows have 4 legs and ducks have 2. Lets say that c is cows and d is ducks. You would have the equations ...
c+d=8
4c+2d=26
well d techniacally = 8-c, so plug in (8-c) for the value of d
4c+2(8-c)=26. Distribute to get
4c+16-2c
and then add like terms. Soy ou would get
2c+16=26.
then just isolate the variable but subtracting 16 from both sides and dividing 2 on both sides. The answer you would get is that c=5 so there are 5 cows. Plug in 5 for c so you get 5+d=8 and tadaaaa you subtract 5 from both sides to get that there are 3 ducks.

How many ways are there to make change for $3? (Utilize all forms of US currency, such as Silver dollars, half dollars, quarters, nickels, & pennies.) Is there a specific formula to calculate this?
Answer:
300 pennies. 12 quarters. 6 half dollars. 3 silver dollars. 60 nickles. 30 dimes.
Step-by-step explanation:
Pennies have a value of .01 so we add that to equal 300. For three dollars we need 12 quarters. 300 divided by the value of the quarter which is .25 cents. We have six half dollars (we divide 300 by the value of the half dollar). We would need 3 silver dollars since each is worth a dollar each. We would need 30 dimes (300 divided by 10). Finally, we would need 60 nickels (300/5 = 60).
I hope this helps. Feel free to ask any questions.

∠A and ∠B are vertical angles with m∠A=x and m∠B=4x−30.
What is m∠A?
Answer:
m<A=10
Step-by-step explanation:
I left the image below to show my work of how i got to that answer. I hope this helps!
We know vertical angles have same measure!
Thus!
A = B
=> X = 4X -30
=> 3X = 30
=> X = 10
Thus measure of angle A is 10°Check off all factors of the given number 9,301

What is the image of (3, 6) when it is translated along the horizontal vector -2,0?
Answer: (1,6)
The vector <-2,0> means we shift the input point two units to the left.
This is the same as writing the rule [tex](x,y) \to (x-2,y)[/tex]
Subtract 2 from the x coordinate. The y coordinate stays the same.
After the translation the point becomes P'(1, 6).
What is the difference between upward, downward, leftwards and rightwards translation?Upward translation : [k] units = When the upward translation take's place then, each point will have its y - coordinate shifted upwards by +k units.Downward translation : [k] units = When the downward translation will take place then, each point will have its y - coordinate shifted downwards by -k units.Leftward Translation : [k] units = When the leftward translation will take place then, each point will have its x - coordinate shifted by -k units to the left.Rightward Translation : [k] units = When the rightward translation will take place then, each point will have its x - coordinate shifted by +k units to the rightGiven is a coordinate point (3, 6).
The horizontal vector is given by -
A = - 2i + 0j + 0k
A = - 2j
When the point is translated along the vector, then, we can write -
P(3, 6) → P'(3 - 2, 6) → P'(1, 6)
P'(1, 6)
Therefore, after the translation the point becomes P'(1, 6).

Which system of equations is equivalent to the following system?
4x + y = 4
2x + 7y = 28
Answer:
the third one
-28x-7y=-28
2x+7y=28
Step-by-step explanation:
for the first one, the 2x+7y=28 is being multiplied by -1, but its not being distributed correctly (28 is incorrect, it should be -28)
for the second one, the 2x+7y=28 is being multiplied by -4, but again, is not being distributed correctly (112 is incorrect, it should be -112)
for the fourth one, 4x+y=4 is being multiplied by -2, but its not being distributed correctly (8 is incorrect, it should be -8)
The system of equations equivalent to the given system is -28x -7y = -28, 2x + 7y = 28, the correct option is C.
What is System of Equation?The system of equation is set of equations which have a common solution.
The system of equation is,
4x +y = 4
2x +7y =28
The equations can be solved using Substitution method, elimination method and by plotting the graph.
In substitution method, the value of one variable from an equation is substituted in the other equation.
4x +y = 4
y = 4 - 4x
This will be substituted in the equation 2
2x + 7 (4-4x) = 28
2x +28 - 28x = 28
-26x = 0
x = 0
Putting this value in equation 1 , y = 4.
In elimination method, one of the variable is eliminated to solve the system of equation.
To eliminate y, the equation 1 will be multiplied by -7,
-28x -7y = -28
2x + 7y = 28
This is equivalent to the original system of equation.
Adding the equations will yield
-26x = 0
x = 0
y = 4.

Step-by-step explanation:
Remember that domain is left to right, and range is down to up.
Question asks to find where the domain is increasing
Increasing means when the line increases
look left, the line extends infinitely in the negative direction: -infinity
There is a discontinuity at 1, and then the line decreases. So that would be the second point

Find a pattern, then select the next two terms of the sequence.
5, 1, 7, 0, 9, –1, 11, . . .
Answer:
-2 and 13
Step-by-step explanation:
the pattern here is annoying to find, but there is one. the first change is -4, then +6, then -7, then +9. The pattern starts at -4, then after that it increases by 2 and changes from a negative to a positive (and can change the other way). After that change it increases by one and changes from a positive to a negative. Essiently, the pattern is add 2 to the pattern and change the sign, then add 1 to the pattern after that and change the sign, infinitely repeating, with the two after 11 being -2 (gotten from +12 because you add 2 to -10 and change the sign) and 13 (gotten from -13 because you add 1 and change the sign of +12).

Answer:
what's the question
Step-by-step explanation:
Answer: So he has 84 animals was there a question to this or is Brian flexing his barn?
Step-by-step explanation:
Give five elements of the following sets.
A = {different land forms}
B = {x/x is a prime number greater than 20 but less than 50}
C = {even number less than 20}
D = {fraction less than 1}
E = {noun that starts with letter "a"}
Answer:
Find the answer below.
Step-by-step explanation:
1. A = {mountain, valley, plateau, plains and hills}
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain.2. B = {23, 29, 31, 37 and 41}
A prime number can be defined as any number that is greater than one (1) and can only be divided by itself or one (1). In this case, they are greater than 20 but less than 50.3. C = {2, 4, 8, 10 and 12}
An even number can be defined as any number that can be divided by two (2) without any remainder. In this instance, they should be between one (1) and twenty (20).4. D = {2/3, 1/2, 3/4, and 1/5}
A fraction that is less than one (1) refers to a proper fraction. Therefore, proper fractions must have the value of their numerator to be less than the value of their denominator.5. E = {ant, angel, angle, anaconda, and ark}
A noun can be defined as the name of any place, people, animal or things. In this context, the nouns should all start with the letter "a."You purchase a burrito for $8.39 and a juice for $2.25. You pay for both items with a $10 bill and a $5 bill. Complete a verbal model for the problem. Then find how much change you receive.
Answer:
You will get $4.36 back.
Step-by-step explanation:
You have to total the cost of the food and drink.
8.39 + 2.25 = 10.64
You give your total money to the cashier to pay for your goods.
10 + 5 = 15
The cashier will give you the refund or change back.
15 - 10.64 = 4.36
