Answer:
not a function
Step-by-step explanation:
for example
In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.
For x2+y2=9
XXXXif (for example) x=0
XXXXthere are two values for y (namely +3 and −3) which satisfy the equation
and therefore the equation is not a function.

A shopper bought the following items at the farmer’s market:
6 ears of corn for $1.80. What was the cost per ear?
12 apples for $2.88. What was the cost per apple?
5 tomatoes for $3.10. What was the cost per tomato?
How do you find out the problem?
What would happen if the decimal was put in the wrong place?
Answer:
$0.30 per corn
$0.24 per apple
$0.62 per tomato
Step-by-step explanation: you divide the price by the amount to give you the per item cost. If you put the decimal in the wrong spot your coat could go from $.30 per corn to $3 per corn. big difference!

Y=2x
Y=7x-20
I’ll give you brainlessly
Answer:
(4,8)
Step-by-step explanation:
y = 2x
y = 7x-20
Step 1: plug in 2x for y
Step 2: subtract 7x on both sides
Step 3: divide by -5 on both sides
Step 4: plug in 4 into y = 2x
2x = 7x -20
-7x -7x
-5x = -20
-5 -5
x = 4
y = 2(4)
y = 8

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1
Isabel’s class has collected 90 cans in a food drive. They plan to sort the cans into n bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.
Answer:
90/n
Step-by-step explanation:
There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.

calculate the value of 1/3 a = -5
Answer:
- 15
Step-by-step explanation:
[tex] \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15[/tex]
Answer:
-15
Step-by-step explanation:
As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Solve the system by substitution.
y = 5x
y = 9x + 4
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

In 8 hours if Martha writes 2 essays, how many essays can she write in 15 hours?
Answer:
Martha can write 3.75 essays in 15 hours. (Which is a lot for me)
Step-by-step explanation:
First, I divide 2 by 8.
2 ÷ 8 = 0.25
Next I multiply 0.25 by 15.
0.25 * 15 = 3.75
So, the answer is 3.75
Hope this helps! :)
Step-by-step explanation:
in 8 hours she wrote = 2 essay
in 1 hour she wrote = 2/8 = 1/4
in 15 she wrote = 15 × 1/4 = 15/4 or 3.75 essays .

The total cost of making a daily taco special for a restaurant is represented by the function C (t) = 2.5t + 1 , where t is the number of tacos made. How does the total cost change for every taco special the food truck makes?
A. The total cost increases by $1.
B. The total cost increases by $2.50.
C. The total cost decreases by $1.
D. The total cost decreases by $2.50.
Answer:
C. The total cost increases by $2.50
Step-by-step explanation:
This is because 1 dollar is constent--- you will always have 1 dollar.
However 2.5 is the change, you have to times a number to get the answer.
EX:
(t) = 2.5t + 1
(4) = 2.5( 4) + 1 ----- plug in 4 for t
= 10 +1
= 11
The is the multiplyer or change is the 2.5t
and when you graph it it will almost always be the slope of the line.

Choose the linear inequality that describes the graph. The gray area represents the shaded region.
4x – 6y ≥ 10
4x + 6y ≤ 10
4x + 6y ≥ –10
4x + 6y ≥ 10
please help !
Answer:
4x+6y<=10
Step-by-step explanation:
The linear inequality that describes the graph is 4x+ 6y ≤ 10.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
As, The bold straight line passes through the points (1,1) and (-2, 3).
so, equation of line will be
(y- 1) = (3-1)/ (-2-1) (x-1)
y-1 = 2 / (-3) (x-1)
-3y + 3 = 2x - 2
-3y -2x = -5
If we multiply by 2 both side we get
-6y - 4x = -10
4x+ 6y= 10
So, the required inequality for gray area is 4x+ 6y ≤ 10.

What is the sign of f on the interval?
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending S15 a week. Write a system of equations that model the following situation.
Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]
Sam : [tex]y=\$705-\$15x[/tex]
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]
The equation for Nancy:
[tex]y=\$425+\$25x[/tex]
2)
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
Let the number of weeks Sam spending his money be 'x'
Let the total amount of money left in Sam's bank after x weeks ='y'
[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]
The equation for Sam:
[tex]y=\$705-\$15x[/tex]
