What’s 4(-8x+5)-(33x-26)=

Answers

Answer:

x = -6/65

Step-by-step explanation:

Perform the indicated multiplications:  4(-8x+5) - 1(33x-26), obtaining:

-32x + 20 - 33x + 26

Combining like terms, we get

-65x = 6, or

x = -6/65

Is the decimal for 4 over 3 a repeating decimal ? expain

Answers

Yes, the decimal form of (4)/(3)is indeed a repeating decimal. The expression is equivalent to 1 (1)/(3), which is also 1.3333333 or "1.3 bar", signifying that the 3 will repeat infinitely.

Either using a calculator or long division, we can show that 4/3 = 1.333333...

Because this string of 3's goes on infinitely, 4/3 is indeed a repeating decimal.

What is the equation of the line –3x–2y=30 in slope-intercept form?

Answers

Answer

y = (-3/2)x - 15


Explanation

The general linear equal in slope intercept form is y = mx + c.

Where m is the slope and c is the y-intercept.

–3x–2y=30 in slope-intercept form

–3x–2y=30

-2y = 3x + 30

y = (-3/2)x - 15

Answer:

y = (-3)/(2)x - 15  

Step-by-step explanation:

We are given the following information in the question:

We are given equation of line:

-3x-2y = 30

The slope intercept form of a straight line is given by:

y = mx +c

where m is the slope of the line and c is the y intercept of the line.

Considering the given equation of the line:

-3x-2y = 30\n-2y = 3x + 30\ny = \displaystyle(3x + 30)/(-2)\n\ny = (-3)/(2)x - 15

is the required form of line.

where the slope of the given line is m = (-3)/(2) and y-intercept is c = -15
