Solve the inequality <br><br> −10 ≤ 2x - 4 < 8

Roman55 [17]

Answer:

- 3 is greater than or equal to x is greater than or equal to 6

Step-by-step explanation:

$- 10 \leq 2x - 4 \leq 8\\\\-10 + 4\leq 2x - 4 + 4\leq 8+4\\\\-6 \leq 2x \leq 12\\\\\\frac{-6}{2} \leq \frac{2x}{2} \leq \frac{12}{2} \\\\-3 \leq x \leq 6$

Hope this helps!!!!

A school director must randomly select 6 teachers to part in a training session. There are 34 teachers at school. In how many di

prohojiy [21]

Answer:

Total possible ways to select 6 teachers from 34 teacher are $^{34}C_6=1344904$ .

Step-by-step explanation:

It is given that total number of teachers at a school is 34.

The school director must randomly select 6 teachers to part in a training session.

$^nC_r=\frac{n!}{r!(n-r)!}$

Where, n is total possible outcomes and r is number of selected outcomes.

Total teachers = 34

Selected teachers =6

Total number of possible ways to select 6 teachers from 34 teacher is

$^{34}C_6=\frac{34!}{6!(34-6)!}$

$^{34}C_6=\frac{34\times 33\times 32\times 31\times 29\times 28!}{6!(28)!}$

$^{34}C_6=1344904$

Therefore total possible ways to select 6 teachers from 34 teacher are $^{34}C_6=1344904$ .

Find the equation of a line that is perpendicular to line g that contains (P, Q). coordinate plane with line g that passes throu

maw [93]

Answer:

$y - Q = - \frac{1}{4}(x - P)$

Step-by-step explanation:

Line g passes through (-2,6) and (-3,2).

The slope of line g is given by:

$\frac{ y_2-y_1}{x_2-x_1}$

Let's substitute the values to get:

$\frac{2 - 6}{ - 3 - - 2}= \frac{ - 4}{ - 1} = 4$

The equation that is perpendicular to line g will have a slope that is the negative reciprocal of 4.

i.e -1/4

If this line passes through (P,Q), then the equation is:

$y - Q = - \frac{1}{4} (x - P)$
