Answer:

2x + y = -4

Step-by-step explanation:

standard form of equation of straight line is

ax+by = c

that  is terms containing x and y should be  on LHS and constant term should be  on RHS

______________________________________________

Given equation

y + 1 = - 2x - 3

lets bring -2x on LHS ,

add 2x on lHS and RHS

y + 1  + 2x = - 2x - 3 + 2x

=> y + 1  + 2x = -3

on lHS, 1 is there which constant term lets bring it on RHS

subtract 1 from both sides

y + 1  + 2x  - 1= -3 -1

y + 2x = -4

rearranging it

2x + y = -4  (Answer)

-x/6 + 6 = 32<br> What is the answer and how do I solve it
masha68 [24]

Answer:

x= -120

Step-by-step explanation:

-x/6+6+6=32

  1. Use -a/b=a/-b= -a/-b to rewrite the fraction.
  2. -x/-6+6+6=32
  3. Add the two 6's then you get 12
  4. -x/-6+12=32
  5. Multiply both sides with the equation by 6
  6. -x+72=192
  7. Move the constant to the right-hand side and change its side
  8. -x=192+72
  9. Subtract the numbers, -x=192-72
  10. -x=120
  11. Change the signs on both sides of the equation
  12. You have your answer it is x= -120

Pls help if you only know the correct answer! Thanks! :)
LiRa [457]

Answer:

A. -3/5 B. 1/5. C. 0.8.

Step-by-step explanation:

Since A is on the left side of 0, it will be negative, in which -3/5 is the only negative answer on there, so A= -3/5. Since B is on the right side of the 0 it's positive, and it is equal to 1/5 which gets you to 0.20, which will be the value of each line since 1 divided by 5 is equal to 0.20. 0.8 is also known as 0.80 so C will be next to the 1.

A deer population is estimated to be 4,350. The growth rate of the population is given by the equation y=4350(1.07) . What is th
HACTEHA [7]

Answer:

Step-by-step explanation:

Analyzing the growth rate of 1.07:

If the growth rate is a number greater than 1, we have exponential growth; if the growth rate is a number greater than 0 but less than 1, we have exponential decay.

Our growth rate is actually growth.  But the rate of growth is not 107%.  The rate of growth means that we already had 100% of the population and that it is growing by 7% each year.  100% + 7% = 107%; as a decimal, 1.07

So the rate of growth is 7%
