Mathematics

poizon [28]4 years ago

Ok, so here your being asked to solve 6x2<span> + 5x = -7 

The procedure that I did was using this formula it led me to get the following:
</span>Using the formula:

x = -(-5) ± √(-5)² - 4(6)(-6)/ 2(6)
x = 5 ± √ 25 + 144 / 12
x = 5 ± √ 169 / 12
x = 5 ± 13/12

x1 = 5 + 13/12
x1 = 18/12
x1 = 3/2

x2 = 5 - 13/12
x2 = -8/12
<span> x2 = - 2/3 

Hope this helped :)</span>

Which Venn diagram correctly describes the relationship between Set R and Set Q?
Tanzania [10]

Answer:

D. because all irrational numbers are real numbers.

Step-by-step explanation:

Real numbers include virtually all numbers we can come up with, either negative or positive, rational or irrational, decimals, etc. They are not imaginary numbers.

Irrational numbers include all numbers that cannot be written as a quotient of two integers. They are numbers whose decimals are never terminating. Examples include π, √2 etc.

Irrational are a subset of real numbers.

Therefore, the correct venn diagram that shows this relationship between Set R {real numbers} and Set Q {irrational numbers} is the venn diagram in option D (last option), because, all irrational numbers are real numbers.

WILL GIVE BRAINLIEST PLZ HELP
avanturin [10]

Answer:

y = -5x - 9.

Step-by-step explanation:

(-2, 1)

(0, -9)

(1 - -9) / (-2 - 0) = (1 + 9) / (-2) = 10 / (-2) = 5 / (-1) = -5

Since -5 is the slope, and the y-intercept is at (0, -9), we have an equation of y = -5x - 9.

Hope this helps!
