Answer:(question8 x=28),(question9 x=18),(question10 x=22),(question11 x=45)

Step-by-step explanation:

Question 8

2x+1+33=90

2x+34=90

2x=90-34

2x=56

Divide both sides by 2

x=56/2

x=28

Question 9

3x+11+25+90=180

3x+126=180

3x=180-126

3x=54

Divide both sides by 3

x=54 ➗ 3

x=18

Question 10

5x+12=6x-10

Collect like terms

6x-5x=12+10

x=22

Question 11

45+3x=180

3x=180-45

3x=135

Divide both sides by 3

x=135 ➗ 3

x=45

Solve the system of equations using the substitution method. -x − 2y = 0 y = -8x (x, y) = ( , )
marta [7]

Answer:

= { \tt{(0, \: 0)}}

Step-by-step explanation:

Let:

{ \bf{ - x - 2y = 0 -  -  - (a)}} \\ { \bf{y =  - 8x -  -  - (b)}}

Substitute for y in equation (b) to equation (a):

{ \tt{ - x - 2( - 8x) = 0}} \\ { \tt{ - x + 16x = 0 }} \\ { \tt{x = 0}}

Also, y = 0

If h(x)=4x - 3 and g(x) = x^2 -3x find g(-3)
Xelga [282]
When you’re told to find g(-3) it just means you’re going into the g(x) equation and replacing the x’s with -3’s. In this case, -3^2-3(-3). =9-(-9) =18

The population of Mathloversville is given by the equation P=38e^0.095t , where t is the number of years from now. How long will
lys-0071 [83]

Answer:

Approximately 107years

Step-by-step explanation:

Given the population of Mathloversville modelled by the equation P=38e^0.095t where t is the number of years from now.

To find the time it will take the population to reach 1million from now, we will substitute P = 1,000,000 into the equation given

1,000,000 = 38e^0.095t

Dividing both sides by 38

1,000,000/38 = e^0.095t

Taking the ln of both sides

ln(1,000,000/38) = ln e^0.095t

ln26,315.79 = 0.095t

10.18 = 0.095t

t = 10.18/0.095

t = 107.16years

It will take approximately 107years for the population to reach 1million
