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)

Step-by-step explanation:

Answer:

a) 5, -3, -4, 0

b)B

Step-by-step explanation:

a) plug in the x values into the equation but be carfeul for squaring negative numbers, they become positive OR read the values from the graph

b)you can see that when x = 0 y= 0 and the only one that goes through the origin is B

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:

1) A reflection across the y-axis

and then

2) A reflection across the x-axis    

Step-by-step explanation:

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

20% of 650

1/5 of 650

130=red

520= not red

Answer:

520

Step-by-step explanation:

20% are red which means 130 are red

650-130= 520

or you could look at it this way

if 20% is red that means 80% is not red

80% of 650 is 520

no

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.

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
