Solve the equation. 25=9x+4-6x

raketka [301]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}$

Step-by-step explanation:

$\star{ \tt{ \: 25 = 9x + 4 - 6x}}$

$\sf{Step \: 1 \: }$ : Collect like terms

Like terms are those which have same base

$\longmapsto{ \sf{25 = 3x + 4}}$

$\tt{Step \: 2 \: }$ : Swap the sides of the equation

$\longmapsto{ \sf{3x + 4 = 25}}$

$\tt{Step \: 3 \: }$ : Move 4 to right hand side and change it's sign

$\longmapsto{ \sf{3x = 25 - 4}}$

$\tt{Step \: 4}$ : Subtract 4 from 25

$\longmapsto{ \sf{3x = 21}}$

$\tt{Step \: 5}$ : Divide both sides by 3

$\longmapsto{ \sf{ \frac{3x}{3} = \frac{21}{3}}}$

$\tt{Step \: 6}$ : Calculate

$\longmapsto{ \sf{x = 7}}$

The value of x is 7

Hope I helped!

F(x)=x^2. What is g(x)

ANTONII [103]

Answer: D

Step-by-step explanation:

I substituted in the value of x (2) to see if it gave me the value of y (1) because that’s the point it gave on g(x).

The only equation that worked was D.

1/2*2=1 then 1^2=1

A random sample of 700 home owners in a particular city found 112 home owners who had a swimming pool in their backyard. Find a

vekshin1

Answer: $(13.28\%,\ 18.72\%)$

Step-by-step explanation:

Given : A random sample of 700 home owners in a particular city found 112 home owners who had a swimming pool in their backyard.

i.e. n= 700 and x= 112

Sample proportion : $\hat{p}=\dfrac{x}{n}=\dfrac{112}{700}=0.16$

z-value for 95% confidence interval : $z_c=1.960$

Now, the 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard will be :-

$\hat{p}\pm z_c\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$=0.16\pm (1.96)\sqrt{\dfrac{0.16(1-0.16)}{700}}$

$=0.16\pm (1.96)(0.013856)\\\\\approx 0.16\pm0.0272\\\\ =(0.16-0.0272,\ 0.16+0.0272)=(0.1328,\ 0.1872)=(13.28\%,\ 18.72\%)$

Hence, 95% confidence interval for the true percent of home owners in this city who have a swimming pool in their backyard : $(13.28\%,\ 18.72\%)$
