What form of a linear equation is y - 6 = -4(x + 2) ?

Mathematics
1 answer:
Softa [21]3 years ago
3 0

Answer:

Point slope form

Step-by-step explanation:

Given

y - 6 = -4(x + 2)

Required

Determine the form of linear equation

A linear has just three forms:

1. The slope intercept form.: This is always in form of y = mx + b

2. The point slope form: This is always in form of y - y_1 = m(x - cx_1(

2. The standard form: This is always in form of Ax + Bxx = c

<em>By comparison, the three forms with the question, we can see that option B answers the question.</em>

Answer:

  A: (3x +4)

  B: (4x +5y) × (4x -5y)

Step-by-step explanation:

<u>Part A</u>:

Since we know the trinomial is a perfect square, we know the terms of each binomial factor are the square roots of the first and last terms of the trinomial.

  9x² +24x +16 = (√(9x²) +√16)² = (3x +4)²

The side of the square is 3x+4.

__

<u>Part B</u>:

The difference of squares is factored like this:

  a²-b² = (a +b)(a -b)

The given area expression is the difference of squares with ...

  a = 4x, b = 5y

so, the factorization is ...

  16x² -25y² = (4x +5y)(4x -5y)

The dimensions of the rectangle are (4x+5y) by (4x-5y).

Answer:

y = 2 \: and \: x = 2.5

y=2x-3

2=2

y = 2x - 3 \\ y =  |2 \times 2.5|  - 3 \\ y = 5 - 3 \\ y = 2 \\

Match each of the following equations according to their slope and y-intercept
satela [25.4K]

Answer:

y=3x goes with m=3, b=0

y=7 goes with m=0, b=7

y=-3x+4 goes with m=-3, b=4

y=1.5x-7 goes with m=1.5, b=-7

y=-1.5x-4 goes with m=-1.5, b=-4

Step-by-step explanation:

The b represents the y- intercept in a graph (where the line crosses the y axis). The m represents the slope of the line. You can find the slope by taking the rise of the graph and dividing it by the run (rise/run). If you get the numbers in the equation form y=mx+b, then you just take the information they give you out of the equation.
