Answer: x = -4/13

Step-by-step explanation:

8x + 1 = 21x + 5

8x + 1 - 21x = 21x +5 - 21x

-13x + 1 = 5

-13x + 1 - 1 = 5 - 1

-13x/13 = 4/-13

x = -4/13

The number 0.35 is one thousandth of what number?
Anni [7]

Answer:

0.35 is one thousandth of 350

Step-by-step explanation:

Let

x ----> the number

we know that

The number multiplied by one thousandth must be equal to 0.35

so

The linear equation that represent this situation is

(\frac{1}{1,000})x=0.35

solve for x

Multiply both sides by 1,000

1,000(\frac{1}{1,000})x=1,000(0.35)\\\\x=350

therefore

0.35 is one thousandth of 350

What is the slope of the line that passes through (-4, 6) and (-6, 20)?
Hatshy [7]

Answer:

-7

Step-by-step explanation:

Since we have two points, we can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 20-6)/(-6- -4)

    = ( 20-6)/ ( -6+4)

    = 14/-2

    = -7
