Answer:

(\frac{13}{3},0) and

Step-by-step explanation:

3x-y=13 \\ \\ -y=-3x+13 \\ \\ y =3x-13

Any point on this line will do.

For this example, let's find the x and y intercepts by plugging in 0 for x and y.

You'll get (\frac{13}{3},0) and (0,-13)(0,-13)

Which of these correctly rearranges the terms in this polynomial so like terms are next to each other?3 – 6x + 4x2 + 3x – 6x2 –
fomenos

Answer:

The rearrangement of the terms is 4x^2-6x^2-6x+3x+3-4.

Step-by-step explanation:

The given expression is

3-6x+4x^2+3x-6x^2-4

Two terms are called like terms if they have same variables having same degree.

In the given expression 3 and -4, -6x and 3x, 4x² and -6x² are like terms.

Arrange the given terms according to their degree and arrange in this way so like terms are next to each other.

4x^2-6x^2-6x+3x+3-4

Therefore the rearrangement of the terms is 4x^2-6x^2-6x+3x+3-4.

A mathematics Teacher brought 40 expensive calculator at 16400 each and a number of cheaper calculator costing tshs 5900 each. S
Novay_Z [31]

Answer:

20

Step-by-step explanation:

First, let's find how much she spent on the expensive calculators

40 times $16400= $656,000

Now, lets find how much money she had for the cheap calculators.

$774,000- $656,000=$118000

Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.

$118000/$5900=20
