What is the answer for3+2x=-6x+4

Mathematics
1 answer:
bixtya [17]3 years ago
6 0

Answer:

x = 1/8 or in decimal form x = 0.125

Step-by-step explanation:

<u>Step 1:  Subtract 4 from both sides</u>

<u />3 + 2x - 4 = -6x + 4 - 4

2x - 1 = -6x

<u>Step 2:  Subtract 2x from both sides</u>

<u />2x - 1 - 2x = -6x - 2x

-1 = -8x

<u>Step 3:  Divide both sides by -8</u>

<u />-1 / -8 = -8x / -8

1/8 = x

x = 0.125

Answer:  x = 1/8 or in decimal form x = 0.125

A rectangle has an area of 24 cm2 Function f gives the length of the rectangle, in centimeters, when the width is w cm. Determin
levacccp [35]

Answer:

Input is the value of w and the function f = 24/w as length x breadth = area of rectangle

If w = 0.5, then f = 24/0.5 = 48cm. So, it is a possible input of the function.

If w = 48, then f = 24/48 = 0.5cm. So, it is a possible input of the function.

If w = 0, then f = 24/0 = 0cm. So, it is not a possible input of the function as it cannot be defined

If w = -6, then f = 24/-6= -4cm. So, it is not a possible input of the function as a length and width can't be negative

If w = 3, then f = 24/3 = 8cm. So, it is a possible input of the function.

A segment has an endpoint at (1,−2). The midpoint is at (−4,−2). What are the coordinates of the other endpoint?
vodka [1.7K]

Answer:

The other midpoint is located at coordinates (-9,-2) (Second option)

Step-by-step explanation:

<u>Midpoints</u>

If P(a,b) and Q(c,d) are points in \mathbb{R} ^2, the midpoint between them is the point exactly in the center of the line that joins P and Q. Its coordinates are given by

\displaystyle x_m=\frac{a+c}{2}

\displaystyle y_m=\frac{b+d}{2}

We are given one endpoint at P(1,-2) and the midpoint at M(-4,-2). The other endpoint must be at an equal distance from the midpoint as it is from P. We can see both given points have the same value of y=-2. This simplifies the calculations because we only need to deal with the x-coordinate.

The x-distance from P to M is 1-(-4)=5 units. This means the other endpoint must be 5 units to the left of M:

x (other endpoint)= - 4 - 5 = - 9

So the other midpoint is located at (-9,-2) (Second option)

Write the expression in factored form s^2-20s-100
KatRina [158]

Answer:

The factors of given expression are 10+10√2 and 10-10√2.

Step-by-step explanation:

We have given a quadratic expression.

s²-20s-100

We have to find factors of given expression.

We use quadratic formula to find factors.

x = (-b±√b²-4ac) / 2a

From given expression, a = 1 , b = -20 and c = -100

Putting values in above formula, we have

x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)

x = (20±√400+400 ) / 2

x = (20±√800) /  2

x = (20± √400×2) / 2

x = (20±20√2) / 2

x = 10±10√2

Hence, the factors of given expression are 10+10√2 and 10-10√2.
