Answer:

1. 1, 2. -15, 3. -18, 4. -1, 5. -11. 6. 22

Step-by-step explanation:

REMEMBER: If a positive multiplies a negative, it will result in a negative. If a negative multiplies a negative, it will resolve as a positive

1. 7 - 2 x 3 = 1

First, multiply 2 and 3 to get 6

7 - 6

Subtract the numbers to get 1

2. -8 + 14 / (-2) = -15

First, do 14 divided by -2 to get -7

-8 + -7

Add the two numbers to get -15

3. -6 + (-3) x 4 = -18

First, multiply -3 and 4 to get -12

-6 + -12

Add the two numbers together to get -18

4. 48 / (-12) +3 = -1

Divide 48 and -12 to get -4

-4 + 3

Add the two numbers to get -1

5. 16 / (-2) -3 = -11

Divide 16 by -2 to get -8

-8 - 3 = -8 + (-3)

Add the two numbers together to get -11

6. -11 x 4 / (-2) = 22

Work the problem from left to right, start with -11 x 4 to get -44

-44 / -2

Divide the equation to get 22

Write an equation of the line that is perpendicular to y = 1/2
atroni [7]

Answer:

the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)

= -5 = -2x + 15

Step-by-step explanation:

Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).

Using the slope intercept equation,

y = mx +c

m = slope = 1/2

For two lines to be perpendicular, the product of their slopes is -1

Let the slope of the other line be m2

m1×m2 =-1

1/2×m2 = -1

m2 = -1/(1/2) = -2

Slope of line = -2

For points (10, -5), x = 10, y =-5

-5 = -2× 10 +c

-5 = -20+ c

c = -5+20= 15

the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)

-5 = -2x + 15

Need help on this problem

Using an exponential function, it is found that:

  • For Country A, the doubling time is of 43 years.
  • For Country B, the growth rate is of 1.9% per year.

<h3>What is the exponential function for population growth?</h3>

The exponential function for population growth is given as follows:

P(t) = P(0)e^{kt}

In which:

  • P(t) is the population after t years.
  • P(0) is the initial population.
  • k is the exponential growth rate, as a decimal.
  • t is the time in years.

For Country A, we have that k = 0.016. The doubling time is t for which P(t) = 2P(0), hence:

P(t) = P(0)e^{kt}

2P(0) = P(0)e^{0.016t}

e^{0.016t} = 2

\ln{e^{0.016t}} = \ln{2}

0.016t = \ln{2}

t = \frac{\ln{2}}{0.016}

t = 43 years.

For Country B, P(36) = 2P(0), hence we have to solve for k to find the growth rate.

P(t) = P(0)e^{kt}

2P(0) = P(0)e^{36k}

e^{36k} = 2

\ln{e^{36k}} = \ln{2}

36k = \ln{2}

k = \frac{\ln{2}}{36}

k = 0.019.

For Country B, the growth rate is of 1.9% per year.

3x+2y=4<br> 8x-3y=-6 solving systems of equations by substitution
Over [174]

Answer:

x=0, y=2. (0, 2).

Step-by-step explanation:

3x+2y=4

8x-3y=-6

---------------

3(3x+2y)=3(4)

2(8x-3y)=2(-6)

-----------------------

9x+6y=12

16x-6y=-12

----------------

25x=0

x=0/25

x=0

3(0)+2y=4

0+2y=4

2y=4-0

2y=4

y=4/2

y=2
