Answer:

Equations that are written in slope intercept form are the easiest to graph and easiest to write given the proper information. All you need to know is the slope (rate) and the y-intercept. Continue reading for a couple of examples! Write the equation for a line that has a slope of -2 and y-intercept of 5.

3-2y-1+5x^2-7y+7+4x^2

MakcuM [25]

Answer: Hi!

The only thing we can do to simplify the equation is combine like terms.

5x^2 + 4x^2 = 9x^2

-2y - 7y = -9y

3 - 1 + 7 = 9

Our equation now looks like this:

9x^2 - 9y + 9

We have nothing left to simplify, so we're done!

Hope this helps!

PLEASE HELP! 25 PTS!!

Answer:

Solution given:

$f(x)=\frac{x-16}{x^2+6x-40}$

$g(x)=\frac{1}{x+10}$

now

f(x)+g(x)= $\frac{x-16}{x^2+6x-40}+\frac{1}{x+10}$ ....(1)

now

factoring x²+6x-40

we get

x²+10x-4x-40

x(x+10)-4(x+10)

(x+10)(x-4)

now substituting in equation 1 ,we get

f(x)+g(x)= $\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}$

taking l.c.m

= $\frac{(x-16)+(x-4)}{(x-10)(x-4)}$

=now

opening bracket

$\frac{x-16+x-4}{x²-10x-4x+40}$

= $\frac{2x-20}{x²+6x-40}$

So

answer is :

B. $\bold b\frac{2x-20}{x^2+6x-40}$

If 95% and 98% confidence intervals were calculated from the same sample data in order to estimate the true cost of an appliance

damaskus [11]

Answer:

D) The z-statistics would be different.

Step-by-step explanation:

Confidence Interval can be calculated using M±ME where

M is the sample mean
ME is the margin of error from the mean

An margin of error (ME) from the mean can be calculated using the formula

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding z-statistic in the given confidence level

s is the population standard deviation

N is the sample size

If 95% and 98% confidence intervals were calculated from the same sample data, then M, s and N are same.

$\frac{s}{\sqrt{N} }$ is called standard error. Since s and N are same the standard errors would also be same.

But, two tailed z-statistic for 95% confidence level is ≈1.96 where for 98% it is ≈2.33
