Answer:

x  = 16

Step-by-step explanation:

The sum of measures of these three angles of any triangle is equal to 180 °

54 + 90 + (2x + 4) = 180

144 + 2x + 4 = 180

148 + 2x = 180

2x = 180 - 148

2x = 32

x= \frac{32}{2} \\\\x=16

Focus on triangle KLM. Since JKLM is a rectangle, angle KLM is right. Since the sum of the interior angles of every triangle is 180, we deduce that

\hat{K}+\hat{L}+\hat{M}=180

Now plug the values for each angle and you have

54+90+(2x+4)=180

Move 54 and 90 to the right side to get

2x+4=36 \iff 2x=32 \iff x=16

PLEASE HELP I will give you a brainliest
Fed [463]

Answer:

when x = -1,  y = -3

when x = -1,  y = -1

when x = -1,  y = 1

when x = -1,  y = 3

Step-by-step explanation:

x = -1;  plug in y = 2(-1) - 1 = -2 - 1 = -3

x = 0;  plug in y = 2(0) - 1 = 0 - 1 = -1

x = 1;  plug in y = 2(1) - 1 = 2 - 1 = 1

x = 2;  plug in y = 2(2) - 1 = 4 - 1 = 3

What is the equation for exponential growth in Biology?
SpyIntel [72]
The exponential growth in biology is A=Pert, where "A" is the ending amount of whatever you're dealing with , "P" is the beginning amount of that same "whatever", "r" is the growth or decay rate, and "t" is time. The formula is related to the compound-interest formula, and represents the case of the interest being "compounded continuously".
