9.43 2.3x-6.7x=-0.3x

1 answer:

7 0

First solve the X factors on the left side: 2.3x - 6.7x = -4.4x 9.43-4.4x=-0.3x Next bring the all the x terms to the same side by adding -4.4x to each side 9.43=4.1x Then divide each side by 4.4 9.43/4.4 X=2.14 I think this is the answer but have to ask what is the sign that goes between 9.43 and 2.3x? This can drastically change the answer. Your goal is to solve for x, you do this by combining like like terms and isolating the the x terms.

Find The distance between (-3,1) and (-1,6). If necessary,round to the nearest tenth.

kifflom [539]

Use distance formula:-

distance = sqrt [ (x2 - x1)^2 + (y2 - y1)^2) ]

let (x1,y1) = (-3,1) and (x2,y2) = (-1,6) Plug these values in to formula.

Given the following perfect square trinomial, fill in the missing term. <br><br> x2 − 16x + ____

soldier1979 [14.2K]

To make that a perfect square polynomial,
follow these steps:
1. Take the co-efficient of x term: here -16
2. Divide it by 2: -16/2 = -8
3. Square it. : (-8)^2 = 64

Thats it! 64 is the missing term you need :)

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

(1)

Here m = 6 and b = - 2, then

y = 6x - 2

(2)

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Here m = - 2 and b = 5, then

y = - 2x + 5 ← equation in slope- intercept form

Add 2x to both sides

2x + y = 5 ← equation in standard form

(3)

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (6, - 13) and (x₂, y₂ ) = (- 4, - 3)

m = $\frac{-3+13}{-4-6}$ = $\frac{10}{-10}$ = - 1 , then

y = - x + b ← is the partial equation

To find b substitute either of the 2 points into the partial equation

Using (- 4, - 3 ) , then

- 3 = 4 + b ⇒ b = - 3 - 4 = - 7

y = - x - 7 ← equation in slope- intercept form

Add x to both sides

x + y = - 7 ← equation in standard form
