Answer:

Find the slope of the line. Do that by putting the equation in slope-intercept form, y = mx + b. That means solve for y.

9x+3y = 36

3y= - 9x + 36

y = -3x + 12

The slope, m = -3

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

The slope of lines parallel is the same.

The slope of lines perpendicular is the negative inverse, m = +1/3

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

Use y = mx + b and the point (1,2) to find b.

2 = (1/3)*1 + b

b = 5/3

The equation is y = (1/3)x + 5/3 (slope-intercept form)

x - 3y = -5 (standard form)

Answer:

he explanation is shown below:

1. You must keep on mind the information given in the exercise:

- She bough 3 pounds of coffee.

- She bought 2 pounds of chocolate.

- She spent a total of $24.

2. Therefore, you can call the price per pound of coffee and the price per pound of chocolate .

3. When you multiply 3 pounds by the price per pound of coffee, you obtain the amount of money she spent for 3 pounds. When you multiply 2 pounds by the price per pound of chocolate, you obtain the amount of money she spent for 2 pounds. If you add both amounts, you obtain the total spent, which was $24.

4. Therefore, you can express this as following:

What is the 100th term of the sequence with a1 = 222 and d = -5?

Leokris [45]

Answer: -273

Step-by-step explanation:

This is an arithmetic progression and the formula to find the nth term is given as:

= a + (n-1)d

Therefore, the 100th term will be:

= a + (n-1)d

= a + (100 - 1)d

= a + 99d

where a = 222

d = -5

Therefore, a + 99d = 222 + 99(-5)

= 222 + (-495)

= 222 - 495

= -273

What is the answer please.... need help

Answer:

$f\left(x\right)=x^3-6x^2+3x+10$ is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

$f\left(x\right)=x^3-6x^2+3x+10$

As the highest power of the x-variable is 3 with the leading coefficients of 1.

So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.

solving to get the zeros

$f\left(x\right)=x^3-6x^2+3x+10$

$0=x^3-6x^2+3x+10$ ∵ $f(x)=0$

$Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0$

$\left(x+1\right)\left(x-2\right)\left(x-5\right)=0$

Using the zero factor principle

if $ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)$

$x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0$

$x=-1,\:x=2,\:x=5$

Therefore, the zeros of the function are:

$x=-1,\:x=2,\:x=5$

$f\left(x\right)=x^3-6x^2+3x+10$ is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.
