What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-intercept of 2. A. x - y - 2

sammy [17]

Answer:

The answer is option C

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the line first find the slope

The line has a y intercept of 2 which is

(0 , 2)

Slope of the line using points

( 1 ,1) and (0,2) is

$m = \frac{2 - 1}{0 - 1} = \frac{1}{ - 1} = - 1$

So the equation of the line using point (1,1) is

y - 1 = - 1(x - 1)

y - 1 = - x + 1

x + y - 1 - 1 = 0

We have the final answer as

Hope this helps you

How is factoring a trinomial different than factoring a number?

JulijaS [17]

Answer:

Hope this answers the question.

Step-by-step explanation:

Factoring a number: If you use the number 10, for example, you have to find all the factors to factor it. 1, 2, 5, 10.

Factoring a trinomial: If you use the trinomial x^2 + 16 + 64, for example, to factor it you need to first find what numbers multiply up to 64 and also add up to 16. In this case, those numbers are 8, and so you get (x + 8)^2.

Ana drinks chocolate milk out of glasses that each hold 1/8 of a leader. she has 7/10 of a liter of chocolate milk in her refrig

PIT_PIT [208]

Amount of chocolate milk Ana drinks = $\frac{1}{8}$ liter

Total amount of chocolate milk in refrigerator = $\frac{7}{10}$ liter

We have to determine the total number of glasses she will pour $\frac{1}{8}$ liter of milk from $\frac{7}{10}$ liter of milk.

Total number of glasses will be determined by dividing the total amount of milk by the amount of milk required for one glass

Total number of glasses = $\frac{7}{10} \div \frac{1}{8}$

= $\frac{7}{10} \times 8$

= $\frac{56}{10}$

= 5.6 glasses

So, 5.6 glasses will be poured from the given amount of chocolate milk.

Divide. (6x³ + 2x² + 3x −4) ÷ (x² + 3x +4)

Aloiza [94]

6x³ + 2x² + 3x - 4 is not exactly divisible by x² + 3x - 4.

Given,

The expression : 6x³ + 2x² + 3x - 4

We have to divide the given expression by x² + 3x - 4.

Let's take 6x³ + 2x² + 3x - 4 as p(x) and x² + 3x - 4 as g(x).

If p(x) is divisible by the factors of g(x), then p(x) is divisible by g(x).

So, let's factorize x² + 3x - 4

x² + 3x - 4 = (x - 1) (x + 4)

Now,

p(x) = 6x³ + 2x² + 3x - 4

By using remainder theorem,

If p(1) = 0 and p(4) = 0, then p(x) is divisible by g(x).

So,

p(1) = 6 × 1³ + 2 x 1² + 3 x 1 -4

p(1) = 6 + 2 + 3 - 4

p(1) = 11 - 4

p(1) = 7

Next,

p(4) = 6 x 4³ + 2 x 4² + 3 x 4 - 4

p(4) = 6 x 64 + 2 x 16 + 12 - 4

p(4) = 384 + 32 + 12 - 4

p(4) = 424

Here, p(1) and p(4) is not 0.

So, p(x) is not divisible by g(x).

That is, 6x³ + 2x² + 3x - 4 is not exactly divisible by x² + 3x - 4.
