Answer:

m = -4.33333 or -4 and 1/3

Step-by-step explanation:

m = (-1-12)/(8-5)

m = -13/3

m = -4.3333333

Answer:

x = 10 and y = 2

Step-by-step explanation:

multiply first equation by 5 and 2nd equation by 3 then subtract equation 1 and 2, we get,

10x+15y= 130

9x+15y=120

( -) (-) (-)

x= 10

substituting the value of x in equation 1 we get

2x + 3y = 26

2*10 + 3y = 26

3y = 26-20

y =6/3

y= 2.i hope this helps

Measuring by using Trigonometry

liberstina [14]

Answer:

x approximately = 11.971, y approximately = 0.837

Step-by-step explanation:

the 12 ft is the hypotenuse of the right angle triangle formed

Cos (theta) = adjacent/hypotenuse

so Cos(4) = x/12, solving for x = 11.971

Sin(theta) = opposite/hypotenuse

so Sin(4) = y/12, solving for y = 0.837

Help on logarithmic equations

$D:x\in\mathbb{R^+}\\\\use:\\log_ab-log_ac=log_a(\frac{b}{c})\\\\log_ab^c=c\cdot log_ab\\============================$

$log_6x-2log_62=4log_62\\\\log_6x-log_62^2=log_62^4\\\\log_6x-log_64=log_616\\\\log_6\frac{x}{4}=log_616\iff\frac{x}{4}=16\ \ \ \ |multiply\ both\ sides\ by\ 4\\\\\boxed{x=64}$
