What is the solution of x^2+x-6/x-7<0 PLEASE HELP ME :( (it’s not the 2nd one i already tried it)

blsea [12.9K]

Answer:

the first one $\:x\le \:-3\quad \mathrm{or}\quad \:2\le \:x$

Step-by-step explanation:

Factor $x^2+x-6$ :

Break the expression into groups

$\left(x^2-2x\right)+\left(3x-6\right)$

$\mathrm{Factor\:out\:}x\mathrm{\:from\:}x^2-2x\mathrm{:\quad}$

$x\left(x-2\right)$

$\mathrm{Factor\:out\:}3\mathrm{\:from\:}3x-6\mathrm{:\quad}$

$3\left(x-2\right)$

$x\left(x-2\right)+3\left(x-2\right)$

$\mathrm{Factor\:out\:common\:term\:}x-2$

$\left(x-2\right)\left(x+3\right)$

$\frac{\left(x-2\right)\left(x+3\right)}{x-7}\\$

$\frac{\left(x-2\right)\left(x+3\right)}{x-7}\le \:0$

$\mathrm{Find\:the\:signs\:of\:the\:factors\:of\:}\frac{\left(x-2\right)\left(x+3\right)}{x-7}$

$\mathrm{Identify\:the\:intervals\:that\:satisfy\:the\:required\:condition:}\:\le \:\:0$

$x$

Merge Overlapping Intervals

$x\le \:-3\quad \mathrm{or}\quad \:2\le \:x$

Which statement is true about the graphs of the two lines y = –6 and x = 1/6 ?

ivanzaharov [21]

The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = 1/6 is a vertical line with a slope of 0.

Richard caught f fish two weeks ago and 32 fish last week.

svp [43]

If the answer needs to be in an expression then the answer is 32 + f because we don't know how many fish he caught the first week

Identify the parameter p in the following binomial distribution scenario. The probability of buying a movie ticket with a popcor

choli [55]

Answer: p=0.711

Step-by-step explanation:

The binomial distribution probability formula :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(X) is the probability of success in x trials , p is the probability of success in each trial and n is the total number of trials .

Given : The probability of buying a movie ticket with a popcorn coupon is 0.711 and without a popcorn coupon is 0.289.

If you buy 21 movie tickets, we want to know the probability that more than 14 of the tickets have popcorn coupons.

Then, the event of success is tickets have popcorn coupons.

Hence, the parameter p for the given binomial distribution scenario : p=0.711
