Equation of the line passing through the points 4,11 and -1,-14

Answers

Answer: y = 5x -9

Step-by-step explanation:

first grt slope:

m = rise / run

m = (11- -14) / (4 - -1)

m = (25) / (5) = 5

y - 11 = 5* (x - 4)

Y = 5x -9

In the parking lot at Central, there are 21 blue cars and 75 cars total. What is the ratio of blue cars to cars that are not blue in simplest form?

Answers

Answer: The ratio of blue cars to cars that are not blue in simplest form = 7:18

Step-by-step explanation:

Given: There are 21 blue cars and 75 cars total.

Then, number of cars that are not blue = 75 -21 = 54

Now, the ratio of blue cars to cars that are not blue = $(21)/(54)=(7)/(18)$ [Divide numerator and denominator by 3.]

Hence, the ratio of blue cars to cars that are not blue in simplest form = 7:18

Rewrite the expression x^3+10x^2+13x+39/x^2+2x+1 in the form of q(x)+r(x)/b(x)

Answers

$(x^3+10x^2+13x+39)/(x^2+2x+1)$

$x^3=x\cdot x^2$ , and $x(x^2+2x+1)=x^3+2x^2+x$ . Subtracting this from the numerator gives a remainder of

$(x^3+10x^2+13x+39)-(x^3+2x^2+x)=8x^2+12x+39$

$8x^2=8\cdot x^2$ , and $8(x^2+2x+1)=8x^2+16x+8$ . Subtracting this from the previous remainder gives a new remainder of

$(8x^2+12x+39)-(8x^2+16x+8)=-4x+31$

$-84x$ is not a multiple of $x^2$ , so we're done. Then

$(x^3+10x^2+13x+39)/(x^2+2x+1)=x+8+(-4x+31)/(x^2+2x+1)$

Write 10 1/3 as an improper fraction

Answers

The 10 1/3 written as the improper fraction31/3.

To convert the mixed number 10 1/3 into an improper fraction, follow these steps:

Multiply the whole number (10) by the denominator of the fraction (3):

10 × 3 = 30

Add the result from step 1 to the numerator of the fraction (1):

30 + 1 = 31

Place the result from step 2 over the original denominator (3) to form the improper fraction:

10 1/3 = 31/3

Step-by-step explanation:

4x+17/18-13x-2/17x-32+X/3= 7x/12-x+16/36

Answers

Answer:To solve the equation 4x + 17/18 - 13x - 2/17x - 32 + x/3 = 7x/12 - x + 16/36, we can follow these steps:

1. Combine like terms on each side of the equation.

On the left side, we have 4x - 13x + x/3. Simplifying this, we get -8x + x/3.

On the right side, we have 7x/12 - x + 16/36. Simplifying this, we get -5x/12 - x + 4/9.

2. Get rid of any fractions by multiplying each term by the least common denominator (LCD).

The LCD of 3, 12, and 36 is 36. Multiply each term on both sides of the equation by 36 to eliminate the fractions.

3. Simplify and combine like terms.

On the left side, we have -8x + x/3, which becomes -24x + x^2/3 after multiplying by 36.

On the right side, we have -5x/12 - x + 4/9, which becomes -15x - 3x + 16 after multiplying by 36.

4. Move all terms to one side of the equation.

Combining like terms, we get -24x + x^2/3 = -18x + 16.

5. Multiply the entire equation by 3 to eliminate the fraction.

This gives us -72x + x^2 = -54x + 48.

6. Move all terms to one side of the equation again.

Combining like terms, we get x^2 + 18x - 48 = 0.

At this point, the equation is a quadratic equation. To solve it, we can either factor or use the quadratic formula.
