Answer:

y = -10/3x - 5

Step-by-step explanation:

slope intercept form:

y = mx + b

10x - 3y = -15

subtract 10x from both sides of the equation

10x - 10x - 3y = -15 - 10x

3y = -15 - 10x

3y = -10x - 15

divide the equation by 3

3y/3 = -10x/3 - 15/3

y = - 10x/3 - 5

Answer:

To write 14.7 as a fraction you have to write 14.7 as the numerator and put 1 as the denominator. Now you multiply the numerator and denominator by 10 as long as you get in the numerator the whole number.

14.7 = 14.7/1 = 147/10

And finally, we have:

14.7 as a fraction equals 147/10

The 8:19 ratio is the bottles of cherry to the total amounts of bottles

Step-by-step explanation:

im not sure what a model would look like but here's one part of the question

The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

Given is that a hair stylist has three colors of hair dye. She has 4 bottles of chestnut, 7 bottles of blond, and 8 bottles of cherry.

Total number of bottles = 8 + 7 + 4 = 19

Total number of cherry bottles = 8

The ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

Therefore, the ratio 8 : 19 will represent the ratio of total number of cherry bottles to the total number of bottles.

Step-by-step explanation:

Answer:

slope m=--3/-2=-3/2 is required slope

Answer:

m = -3, b = -2

Step-by-step explanation:

The equation is written in the form of slope-intercept, where m = slope and b = y-intercept.

The slope is the number before x. For the equation y = -3x - 2, it's -3.

The y-intercept is the constant. For the equation y = -3x - 2, it's -2.

Hence, m = -3, and b = -2.

Answer:

$288

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 18%/100 = 0.18 per year,

then, solving our equation

I = 3200 × 0.18 × 0.5 = 288

I = $ 288.00

The simple interest accumulated

on a principal of $ 3,200.00

at a rate of 18% per year

for 0.5 years is $ 288.00.

The polynomial is given as f(x) = (x - 5)(x + 1)(4x + 1).  

        f(x) = x² − 4x + 7.

Given is a polynomial with zeroes -

x = 5, x = - 1 and x = - 1/4

The given zeroes are -

      (x - 5) = 0

       (x + 1) = 0

       4x = - 1

       (4x + 1) = 0

So, we can write the polynomial as -

f(x) = (x - 5)(x + 1)(4x + 1)  

Therefore, the polynomial is given as f(x) = (x - 5)(x + 1)(4x + 1).

Cubic Function

Step-by-step explanation:

In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.

Answer:

C

Step-by-step explanation:

if you plug the x values into x>10 you'll see that the only set with both numbers greater than ten is C

The solutions to x > 10 are x = 12 and x = 20 shown in option C.

Any two numbers can be compared in a linear inequality statement using symbols such as "<" ">," "≤" or "≥" These values could be algebraic, numerical, or a combination of the two.

Consider the expression x > 10

As x = 0 less than 10, so, this option is incorrect.

Since, both -12 and 0 are less than 10, incorrect option.

Both 12 and 20 are greater than 10. Thus, correct option.

As, x = 5 is less than 10, incorrect option.

Therefore, the solutions for expression x > 10 are x = 12 and x = 20.

Answer:

3 tiles will not fit together.

Step-by-step explanation:

Measure of an Interior angle of a polygon = [tex]\frac{(n-2)\times 180}{n}[/tex]

Here, n = number of sides of the polygon

Therefore, measure of the interior angles of a regular hexagon,

A = [tex]\frac{(6-2)\times 180}{6}[/tex]

A = 120°

Similarly, interior angle of the regular pentagon,

B = [tex]\frac{(5-2)\times 180}{5}[/tex]

B = 108°

Now m∠A + m∠B + m∠C = 360°

m∠C = 360° - (120° + 108°)

        = 132°

To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.

D = [tex]\frac{(8-2)\times 180}{8}[/tex]

D = 135°

m∠C ≠ m∠D

Therefore, 3 tiles will not fit together.
