Write the slope intercept form of the equation given the point (-2,4) and a slope of 3
Hitman42 [59]

Given the points:

(x, y) ==> (-2, 4)

slope, m = 3

To write the slope intercept form, use the form below:

y = mx + b

Where m = slope and b = y-intercept.

Now, substitute -2 for x, 4 for y, and m for 3 in the equation above to solve for b.

We have:

y = mx + b

4 = 3(-2) + b

4 = -6 + b

Add 6 to both sides:

4 + 6 = -6 + 6 + b

10 = b

b = 10

Therefore, the slope intercept form of the equation is:

y = 3x + 10

ANSWER:

y = 3x + 10

What is the product of the polynomials below? (4x^2-2x-4)(2x+4)
Travka [436]

Answer:  8x³ + 12x² - 16x - 16

<u>Step-by-step explanation:</u>

  (4x² - 2x - 4)(2x + 4)

= (2x + 4)(4x² - 2x - 4)

= 2x(4x² - 2x - 4)  +  4(4x² - 2x - 4)

=   8x³ - 4x² - 8x   +  16x² - 8x - 16

=   8x³ + (-4x² + 16x²) + (-8x - 8x) - 16

=   8x³ + 12x² - 16x - 16

Which sets of ordered pairs represent functions from A to B? (Select all that apply.) A = {a, b, c} and B = {3, 4, 5, 6}
sesenic [268]

Answer:

See Explanation

Step-by-step explanation:

<em>The question has mission options; However, the question is still solvable.</em>

Given

A = \{a,b,c\}

B = \{3,4,5,6\}

Required

Determine possible ordered pairs of A to B

A function is of the form (x,y)

Let A be the range of the function and B, the domain

Let (x,y) be a function of A to B, where x represents any of the values in A sets and y represents any of the values in B

A ordered pair can only be regarded as a function if and only if it has unique y-values

Hence, a possible ordered pair is:

(A,B) = \{(a,3),(b,4),(c,5)\}

Another possible ordered pair is

(A,B) = \{(a,4),(b,5),(c,6)\}

<em>Note that there as as many as possible ordered pair as long as the y-values are unique</em>

prove that the fast squaring trick for two-digit numbers ending in 5 works. the trick: if you have a 2-digit number that ends in
blondinia [14]

The procedure to squaring a two digit number is by multiplying the first number by a integer greater than the number and putting 25 beside it.

Finding the Square of a Value is a simple method. Multiply the specified integer by itself to determine the square number. The square term is always represented as an integer multiplied by two. For example, the square of 5 is 25 multiplied by 5, giving 5×5 = 5² = 25.

What if we want to calculate the square root of a two-digit number . It might be a little challenging. Ordinary multiplication cannot be used to compute the square of two-digit values. This article will show us how to calculate the precise square of such integers.

Simply multiply a single-digit number by itself to find its square. Furthermore, by memorizing the tables from 1 to 10.

We taught about two triangles and how to find the point of any base of a triangle given the other two sides using Pythagoras' theorem.

A right triangle has three sides: the hypotenuse, perpendicular, and base. Pythagoras' theorem states that

Hypotenuse² = Perpendicular² + Base².
