Answers

Answer:

x = 30 and y = 50

Step-by-step explanation:

Given that,

The cost of 4 shirts and 1 pair of pants is $170 and the cost of 5 shirts and 2 pair of pants is $250.

Let the cost of 1 shirt is x and that of 1 pant is y.

So,

4x+y=170 .....(1)

5x+2y = 250 .....(2)

Multiply equation (1) by 2.

8x+2y=340 .......(3)

Subtract equation (2) from (3).

8x+2y-(5x+2y)=340-250

3x = 90

x = 30

Put the value of x in equation (1).

4(30)+y=170

120+y=170

y = 170-120

y = 50

Hence, the value of x is 30 and that of y is 50.

Factor this polynomial completely.

which equation represents a line parallel to y= -2x+9

Answers

The equation of the parallel line is:

y = -2x + k

such that k ≠ 9.

How to represent the parallel line?

We know that two linear equations are parallel if they have the same slope and different y-intercept.

Then, a parallel line to:

y = -2x + 9

Would be something of the form:

y = -2x + k

such that k ≠ 9.

Then, for example:

y = -2x + 3

Is parallel to the given line.

Draw an angle of -45 degrees in standard position . Then find the reference angle

Answers

Answer:

45°

Step-by-step explanation:

-45° would be 360°-45°=315°

Since 315° is in Quadrant IV, then its reference angle is 360°-315°=45°

So really, -45° is just 45° clockwise which is also our reference angle.

Explain your answer (be careful he said 1 MONTH).

Answers

Answer:

The poster say, "Open an account of $3,500 and earn at least $10 interest in 1 month!" is correct

Step-by-step explanation:

Given, A bank manager wants to encourage new customers to open accounts with principals of at least $3,500.

He decides to make a poster advertising a simple interest rate of 4.8%.

We have to find what must the principal be if the bank manager also wants to advertise that one can earn $10 the first month

We know that, banks offer simple interest

In our problem, simple interest = $10, rate = 4.8%, time = 1 month

Let us see Can the poster correctly say, "Open an account of $3,500 and earn at least $10 interest in 1 month!"?

So now, in our problem, amount = $3500, rate = 4.8% and time = 1 month =

So, the statement is correct.

Hence, amount to be invested is $2500 and poster says correctly.
