Parallel Lines A line is parallel to y = 2x - 8 and intersects the point (-4,-1). What is the equation of this parallel line?
Assoli18 [71]

Answer:

y= 2x+7

Step-by-step explanation:

Since the line is parallel to y = 2x - 8 it has slope m= 2

The equation of the line passing through (-4,-1) is given by,

\frac{y - ( - 1)}{x - ( - 4)}  = m

\frac{y  + 1}{x + 4}  = 2

y  + 1 = 2(x + 4)

y + 1 = 2x + 8

y = 2x + 8 - 1

y = 2x + 7

Country A has a growth rate of 3.4​% per year. The population is currently 4,118​,000, and the land area of Country A is 29​,000
Eduardwww [97]

Answer:

time period is 260.57 years

Step-by-step explanation:

given data

growth rate = 3.4 % = 0.034

population = 4118000

area  P = 29000000000 square yard

to find out

time period that one person for every square yard of​ land need

solution

we will apply here population growth formula that is

total population P  = initial population × e^{rt}    ..............1

here r is rate of growth and t is time period and

we consider here initial population is current population

so put value in equation 1 to get t

29000000000 = 4118000 × e^{0.034t}

take ln both side

ln 7042.25 = ln e^{0.034t}

8.8596 = 0.034 t

t = 260.57

so time period is 260.57 years

I don't understand this question very well
shepuryov [24]
There are 10 marbles in the bag all together.
(8/10) = 80% of the marbles in the bag are white.

So if you pull a marble out of the bag, you have an 80% chance
of pulling a white one.

And if you do it many times, you expect that you'll pull
a white one out about 80% of the times.

   80% pf 45 times  =  0.8 x 45  =  36 times .

I want solution 1 and 2 with the steps to know the final answer
Delicious77 [7]
Question 1:

Slope = 1/5

y = mx + c 
y = 1/5 x + c
at point (5, -1)
-1 = 1/5 (5) + c
- 1= 1 + c
c = - 2

y = 1/5x - 2
5y = x - 10

Question 2:
slope = (9-5)/(3-1)
Slope = 2

y = mx + c
y = 2x + c

at point (1, 5)
5 = 2(1) + c
c = 5 - 2
c = 3

y = 2x + 3

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was
alekssr [168]
The formula would be set up as ratios (or fractions). The first ratio is 6:5, which in total is 11. There were 6 yes out of 11, so the fraction = 6/11.

The second fraction has a total of 5918, however you do not know the amount of yes votes, so the variable placeholder will be called "x".

The final formula would be:
 6/11 = x/5918

 You do cross multiplication and you get:
11x = 35508. You divide both sides, and you get x = 3228.

Because x is the placeholder for the amount of yes votes, and x = 3228, the amount of yes votes is 3228
