Answer:

-115

Step-by-step explanation:

Using BODMAS

+(-9) = -9

2(-9) = -18

5(-18) = -90

(-90) + (-25) = -90 - 25 = -115

What is the slope of (-12,-12) and (9,-9)

telo118 [61]

Step-by-step explanation:

Slope, which is the same as gradient, is equal to

change in y axis ÷change in x axis

<h3> $slope = \frac{change \: in \: y}{change \: in \: x}$ </h3>

Our coordinates are (-12,-12) and (9,-9)

In (-12,-12),let the first -12 be x1 and the second one be y1

Same goes for the (9,-9), let 9 be X2 and -9l be y2

 $slope = \frac{y2 - y1}{x2 - x1}$ 

 $= - \frac{ - 9 - - 12}{9 - 12}$ 

 $= \frac{3}{21}$ 

=0.1428571429

= 0.1429

Answer:

x : -3

Step-by-step explanation:

1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)

2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)

3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)

4) -6x = 18 (divide the -6 on both sides)

5) x = -3

Answer:

C) 35

Step-by-step explanation:

$^7C_3 \\ = \frac{7!}{3!(7 - 3)!} \\= \frac{7!}{3! \: 4!} \\ = \frac{7 \times 6 \times 5 \times 4!}{3 \times 2 \times 1 \times 4!} \\ = \frac{7 \times 6 \times 5 \times 4!}{3 \times 2 \times 1 \times 4!} \\ = 35 \\ \huge \red{ \boxed{ \therefore \: ^7C_3 = 35}}$
