Did you mean

81* 9∧(-2b-2)=27 => First divide whole equation with 81 and get

(3∧2)∧(-2b-2)=1/3 => 3∧(-4b-4)=3∧(-1) => -4b-4=-1 => -4b= -1+4 => -4b=3 =>

we will multiply whole equation with (-1) and get 4b=-3 => b=-(3/4)

If the start item is correct.

Good luck!!!

Use matrices to write the equation of the function in the form y = mx + b that contains the points
Fofino [41]

The line has a slope of -6 and a y intercept of 7.

The linear equation is given by:

y = mx + b;

where m is the slope of the line, b is the y intercept, y, x are variables.

The equation of the line passing through the points (6.-29) and (-4,31) is:

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-29)=\frac{31-(-29)}{-4-6}(x-6)\\\\y+29=-6(x-6)\\\\y=-6x+7

Hence the line has a slope of -6 and a y intercept of 7.

Dedi had a combination lock.To open the lock he started at 37.He made 3 half turns clockwise and 3 quarter turns anticlockwise
Lerok [7]
Turning clockwise means the number increase, and counterclockwise means the number decreases

Therefore your answer is 37 + (3*1/2)-(3*1/4)

= 37.75

Hope this helped :)
