How would I get this information into Y=Mx+B

One question at a time, please.  I will focus on #16 and ignore #18.

slope:  3/4              line passes thru (-8,2)

Write out    y = mx + b.  Subst. 2 for y.  Subst. -8 for x  Subst. (3/4) for m:

2 = (3/4)(-8) + b.  Find b.           2 = -6 + b    =>           b = 8

So your equation is y = (3/4)x + 8.  Please, use (  ) around those fractions!

Economists predict that Americans will spend $1,180 on Summer Vacation in 2015, this is up 5.6% from 2014. What did Americans sp
netineya [11]

Answer: $1117.42

Step-by-step explanation:

Given: The amount predicted by Economist =$1180

Let x be the amount spent by Americans on Summer vacation in 2014.

Therefore,  According to the question, we have

5.6% of x+x=1180

\Rightarrow0.056\timesx+x=1180\\\Rightarrow x(0.056+1)=1180\\\Rightarrow\ x=\frac{1180}{1.056}=1117.42\approx

Hence, the amount spent by Americans on Summer vacation in 2014 = $1117.42

The ratio of working-age population to the elderly in the United States (including projections after 2000) is given by the funct
Dovator [93]

Answer:

a) Sketch the graph of the function f. (it is in the attached file)

b) What was the ratio at the beginning of 2006? At the beginning of 2014?

For 2006 the ratio is 3.92

For 2014 the ratio is 3.5

c) Over what years is the ratio constant?

[1995, 2000]

d) Over what years is the decline of the ratio greatest?

[2010, 2030]

Step-by-step explanation:

b) We first need to know in between which function 2006 falls into, so if we start in t=0=1995, then 2006-1995=11, t=11

t=11 fall into:

f(x)=-0.03t+4.25

f(11)=-0.03(11)+4.25=3.92

For 2006 the ratio is 3.92

2014:

Same process that 2006, t=0=1995, then 2014-1995=19, t=19

t=19fall into:

f(x)=-0.075t+4.925

f(19)=-0.075(11)+4.925=3.5

For 2014 the ratio is 3.5

c) The ratio is only constant in the first section of the graph 0≤t<5, since 4.1 is constant. Following the same process for the years in star (b) we have t=0, 1995+0=1995, t=5, 1995+5=2000.

The ratio will be constant between [1995, 2000]

d) For the greatest decline we need to compare slopes. From the line equation we have:

y(x)=mx+b where m is the slope and b is the point the line intersects with the y axis. Here we have:

f(x)=-0.03t+4.25  for 5≤t<15

f(x)=-0.075t+4.925  for 15≤t≤35

So:

m=-0.03 for 5≤t<15

m=-0.075 for 15≤t≤35

If we are measuring the steepness of the decline, we have to compare:

|-0.03| and |-0.075| or 0.03 and 0.075, easily finding that 0.075>0.03

And doing the sames process for the years in question (c):

t=15, 1995+15=2010, and t=35, 1995+35=2030

This means that the biggest decline is between the years:

[2010, 2030]

Voting An appropriations bill passes the U.S. House of Representatives with 49 more members voting in favor than against. If all
sukhopar [10]

Answer:

242 members voted in favor while 193 members voted against

Step-by-step explanation:

Let those that voted against be x will those in favor will be (x+49)

Since today number of voters is 435

To find x

X + (x+49) = 435

2x + 49 = 435

2x = 435 - 49

2x = 386

X = 386/2

X = 193

Therefore, those against is 193 while this in favor is 193+49 = 242
