The only linear equation that matches the graph is: Option E: y = 2/3 x

What is the equation of the line?

The general form for the equation of a Line in slope intercept form is:

y = mx + c

Where:

m is slope

c is y-intercept

We can find the slope between two coordinates using the formula:

m = [tex]\frac{(y_{2} - y_{1}) }{(x_{2} - x_{1})}[/tex]

Using the given coordinates (-3, -2) and (3, 2), we have:

m = (2 - (-2))/(3 - (-3))

m = 4/6 = 2/3

The only equation with slope of 2/3 is Option E

Answer:

The price of the burrito is $3.5 and the price of the taco is $2.5.

Step-by-step explanation:

2x+5y=19.5

5x+2y=22.5

------------------

5(2x+5y)=5(19.5)

-2(5x+2y)=-2(22.5)

-----------------------------

10x+25y=97.5

-10x-4y=-45

-----------------------

21y=52.5

y=52.5/21=2.5

2x+5(2.5)=19.5

2x+12.5=19.5

2x=19.5-12.5

2x=7

x=7/2=3.5

x=3.5, y=2.5

The price of the burrito is $3.5 and the price of the taco is $2.5.

The required price of the burrito is $3.50 and the price of the taco is $2.50.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's represent the price of a burrito b and the price of a taco t.

If two students have burritos, then the cost of the burritos is 2b.

If five students have tacos, then the cost of the tacos is 5t.

The total cost of the meal is 2b + 5t = $19.50.

Similarly, if five students have burritos, then the cost of the burritos is 5b.

If two students have tacos, then the cost of the tacos is 2t.

The total cost of the meal is 5b + 2t = $22.50.

We can set up a system of equations to solve for b and t:

2b + 5t = $19.50

5b + 2t = $22.50

We can solve this system using the elimination method. Multiplying the first equation by 5 and the second equation by 2, we get:

10b + 25t = 97.50

10b + 4t = 45.00

Subtracting the second equation from the first equation, we get:

21t = 52.50

t = $2.50

Substituting this value for t into the first equation, we get:

2b + 5 x $2.50 = $19.50

2b = $7

b = $3.50

Therefore, the price of a taco is $2.50 and the price of a burrito is $3.50.

Answer:

We should invest 9600 .

Step-by-step explanation:

Interest received in Two and a half year = 1,200

So, Interest that should be received in a year = 1200×[tex]\frac{2}{5}[/tex]

                                                                            = 480

Interest rate = 5%.

Let we had invested  amount X.

Thus 5 % of X we will get in a year as interest

Which is [tex]\frac{5}{100}[/tex]×X = [tex]\frac{X}{20}[/tex].

It is also equal to 480 as calculated above,

So. X = 480×20 = 9600.

Thus,

Answer:

The first mechanic worked for 20 hours and the second mechanic worked for 5 hours

Step-by-step explanation:

Let f be the number of working hours of first mechanic

Let s be the number of working hours of second mechanic

Given that they both worked for a combined total of 25 hours

⇒f + s = 25 → equation 1

First mechanic charged $95 per hour and second mechanic charged $90 per hour and they both together charged $2350

⇒95f + 90s = 2350 → equation 2

Using equation 1 in equation 2:

95f + 90(25-f) = 2350

⇒95f + 2250 - 90f = 2350

⇒5f = 100

or f = 20 hours

⇒s = 25 - f ⇒ s = 5 hours

The first mechanic worked for 20 hours and the second mechanic worked for 5 hours

For this case we have the following inequality:

[tex]-5y \leq-15[/tex]

To solve, we follow the steps below:

We divide between 5 on both sides of the inequality:

[tex]-y \leq \frac {-15} {5}\\-y \leq-3[/tex]

We multiply by -1 on both sides taking into account that the sense of inequality changes:

[tex]y \geq3[/tex]

Thus, the solution is given by all values of "y" greater than or equal to 3.

Answer:

[tex]y \geq3[/tex]

Answer: The Customers have to spend $4000 in order to raise $1000 for the pet rescue program.

Step-by-step explanation:

Hi, to answer this question we have to write a proportion.

Proportion = money spent / money raised for the pet rescue program

For every $120 that customers spend, $3: 120/3

To raise $100 : x / 100

Where x is the money that customers spent to raise $100 for the pet rescue program.

Solving for x:

Final answer:

An absolute value inequality that includes 3 and -6 as solutions is |x + 1.5| ≤ 4.5. Both numbers satisfy the inequality when substituted for x.

Explanation:

To write an absolute value inequality that has 3 and -6 as two of its solutions, we must find an inequality such that both of these numbers satisfy the condition when their absolute values are considered. One such inequality is |x + 1.5| ≤ 4.5.

Let's verify the solutions:

For x = 3: |3 + 1.5| = |4.5| = 4.5, which is less than or equal to 4.5.

For x = -6: |-6 + 1.5| = |-4.5| = 4.5, which is also less than or equal to 4.5.

Therefore, the inequality |x + 1.5| ≤ 4.5 is a valid inequality that includes 3 and -6 as solutions.

Answer:

∠NQP = 74°

Step-by-step explanation:

NPQ is a triangle.

We know the sum of 3 angles of a triangle is 180 degrees. So we can write:

N + P + Q = 180

2x + 34 + 2x + 2 = 180

Now, we can solve for x:

[tex]2x + 34 + 2x + 2 = 180\\4x+36=180\\4x=180-36\\4x=144\\x=\frac{144}{4}\\x=36[/tex]

The measure of NQP is "2x+2", we plug in x = 36, and find the measure of NQP:

∠NQP = 2(36) + 2 = 74°

Final answer:

To find out how many more sweets Gavin gets over Stephan, we use the ratio 1:4:4, knowing that Stephan gets 13 sweets. Gavin, who has 4 times Stephan's amount, ends up with 52 sweets, which is 39 sweets more than Stephan.

Explanation:

To determine how many more sweets Gavin gets compared to Stephan, we need to use ratios. Since Stephan, Gavin, and Jim share sweets in the ratio 1:4:4, and Stephan gets 13 sweets, we can assign variables to the parts of the ratio to make this easier to solve. Let's assign 'x' to the value of one part, so Stephan gets 1x=13 sweets.

Since 1x is equal to 13, that means 4x is the amount Gavin gets. Now we calculate 4x, which is 4 [tex]\times[/tex] 13=52 sweets. To find out how many more sweets Gavin gets we subtract Stephan's 13 sweets from Gavin's 52 sweets to get the difference.

So, Gavin gets 52-13=39 sweets more than Stephan.

Answer:

the answer is type 2

Step-by-step explanation:

ok so you first have to find the ratio of all of them and for type 1 it is 40 to 1 for type 2 it is 50 to 1 type 3 is 25 to 1 and type 4 is 30 to 1 so there for type two has the biggest ratio of fragrance to wax

The required table that has a higher ratio of fragrance to wax is type 2.

As given in the question, a company makes four different types of candles. The ratio of fragrance to wax for each type of candle is shown in the tables.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
For Type 1
The ratio of Fragrance to wax.
= 20 / 0.5 = 40 / 1

For Type 2
The ratio of Fragrance to wax.
= 150 / 3 = 50 / 1

For Type 3
The ratio of Fragrance to wax.
= 250 / 10 = 25

For Type 4
The ratio of Fragrance to wax.
= 30 / 1

Now,
50 > 40 > 30 > 25
Type 2 > type 1 > type 3 > type 4

Thus, the required table that has a higher ratio of fragrance to wax is type 2.

Explanation:

If school starts at 8:55 AM and Katie was a quarter of an hour late, that means she was 15 minutes late because a quarter of an hour is 15 minutes (60 minutes divided by 4 equals 15 minutes).

To find out what time Katie arrived, we need to add 15 minutes to the starting time of school:

School starts: 8:55 AM

Time late: + 15 minutes

Time of arrival: 9:10 AM

So, Katie arrived at school at 9:10 AM.

Step-by-step explanation:

The length of basketball court is 32 meters and width is 13 meters.

Step-by-step explanation:

Perimeter = 90 meters

Let w be the width

Length = l = 2w + 6

As basketball court are in rectangular shapes, therefore,

Perimeter = 2(length+width)

[tex]90=2(2w+6+w)\\90=2(3w+6)\\90=6w+12\\90-12=6w\\6w=78[/tex]

Dividing both sides by 6;

[tex]\frac{6w}{6}=\frac{78}{6}\\w=13\ meters[/tex]

Length = 2w+6

[tex]l=2(13)+6\\l=26+6\\l=32\ meters[/tex]

The length of basketball court is 32 meters and width is 13 meters.
