The equations 3x-2y=-14 and 3x+y=-11 are plotted on the same set of axes. what are the coordinates of a point that's common to both equations? how do you know?​

Answers

Answer:

14

Step-by-step explanation:

Answer:

(-4, 1)

Step-by-step explanation:

Solve it as a system of equations:

[tex]3x-2y=-14\\3x+y=-11[/tex]

subtract the two equations

[tex]-3y = -3[/tex]

divide both sides by -3

[tex]y=1[/tex]

Plug this into the equation 3x + y = -11 to solve for x

[tex]3x + 1 = -11\\[/tex]

subtract 1 from both sides

[tex]3x = -12[/tex]

divide both sides by 3

[tex]x = -4[/tex]

So the answer is (-4, 1)

What is the equation, in slope-intercept form, of the line with a slope of -1/3 and y-intercept of (0, 9)? Choices in picture below

Answers

Step-by-step explanation:

The formula is y=mx+b, with m representing the slope, x representing the x coordinate, and b representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.

Answer:

y=-⅓+9

Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.

Answers

Answer:

Step-by-step explanation:

WeMoveU charges an hourly rate for a moving team to load and unload a truck. The charges is a different hourly rate for a team pack and unpack boxes. Use the quotes below to determine the company's hourly rates. Weekday Move: 5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost. Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.

Let us represent:

Hours of Loading and Unloading = X

Hours of packing = y

5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost.

5x + 4y = 730..... Equation 1

Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.

4x + 5y = 710.... Equation 2

Combining both Equations together

5x + 4y = 730..... Equation 1

4x + 5y = 710.... Equation 2

We solve using Elimination method

One month Mai rented 12 movies and 2 video games for a total of $53. The next month she rented 3 movies and 5 video games for a total of $38. Find the rental cost for each movie and each video game.

Answers

Answer:

Movie cost $3.5 and the video game cost $5.5

Step-by-step explanation:

Given data

Let the cost of movies be x

and the cost of video game be y

12x+2y= 53----------1

and

3x+5y= 38-----------2

solve 1 and 2

12x+2y= 53X 5

3x+5y= 38  X2

 60x+10y= 265

- 6x+10y= 76

 54x= 189

x= 189/54

x= $3.5

put x= 3.5 in  1

12(3.5)+2y= 53

42+2y= 53

2y= 53-42

2y= 11

y= 11/2

y= $5.5

Hence the movie cost $3.5 and the video game cost $5.5

Give an example of a two variable function that is not continuous at (1,2) . Explain why your example works.

Answers

Answer:

A two-variable function is something like:

z = f(x, y).

We want this function to not be continuous at (1, 2), this means that x = 1 and y = 2.

Now, a easy way to make a function not continuous at a given point, we can have a denominator that is equal to zero at that particular point, and this is because we can not divide by zero

For example, we could have:

[tex]f(x, y) = \frac{1}{(x - 1) + (y - 2)}[/tex]

The denominator is (x - 1) + (y - 2)

When x = 1, and y = 2, this is equal to zero, then this function is not continuous in the point (1, 2).

Answer:

m2KJL = 54°

Step-by-step explanation:

In AJKL,

MAJKL = 72°

JK = KL

Since, two sides of AJKL are congruent, triangle is an isosceles triangle.

By the property of an isosceles triangle,

Opposite angles of the congruent sides of an isosceles triangle are equal in measure.

Therefore, J = ZL

By the property of a triangle,

Sum of all interior angles of a triangle is 180°.

m2J + m2K + m2L = 180°

mzJ + 72° + mzJ = 180° [Since, mzJ = mzL]

2mzJ = 180° - 72°

mzJ = 54°

Therefore, mZKJL or mzJ is 54°.

A store is offering a 20% discount on all items. Is there a proportional relationship between the original price of an item and its price after the discount?

Answers

Answer:

A store is offering a 14% discount on all items. Write an equation relating the sale price S for an item to its list price L.

Step-by-step explanation:

Yes there is  a proportional relationship between the original price of an item and its price after the discount assuming a store is offering a 20% discount on all items

Let p represent  original price of the commodity

Let the current price be:

Current price (p1)=Original price-Discount amount

Current price (p1)=P-Px20%)

Current price (p1)=p(1-20%)

Current price (p1)=0.8P

Hence:

P1=0.8P

P1÷P=0.8

Based on the above there is  a proportional relationship between the original price of an item and its price after the discount.

Inconclusion Yes there is  a proportional relationship between the original price of an item and its price after the discount assuming a store is offering a 20% discount on all items.
