What is the solution to this system of equations?

Leto [7]

Use the property of substitution to solve:
2 ( x - 2y = 15) ... 2x - 4y = 30
   2x + 4y = -18

subtract..... 4x = 12
divide by 4    x =3 place into original equation 3 - 2y = 15
   -2y = 12
   y = -6

Answer:

The simplified fraction of the expression $\frac{5^2\times 5^{-4}}{5}$ will be:

$\frac{5^2\times \:5^{-4}}{5}=\frac{1}{125}$

Step-by-step explanation:

Given the expression

$\frac{5^2\times 5^{-4}}{5}$

Steps to solve the expression

$\frac{5^2\times 5^{-4}}{5}=\frac{5^{-2}}{5}$ ∵ $5^2\times \:5^{-4}=5^{2-4}$

$=\frac{1}{5^3}$

$=\frac{1}{125}$ ∵ $5^3=125$

Therefore, the simplified fraction of the expression $\frac{5^2\times 5^{-4}}{5}$ will be:

$\frac{5^2\times \:5^{-4}}{5}=\frac{1}{125}$

Shaded=big rectangle-white rectangle

area recangle=base times height=(x+10) times (2x+5)=2x²+25x+50

area white=(x+1) times (x+1)=x²+2x+1

big-white=(2x²+25x+50)-(x²+2x+1)=
2x²+25x+50-x²-2x-1=
x²+23x+49

de area is x²+23x+49

Answer: Null hypothesis: $p\leq0.50$

Alternative hypothesis: $p>0.50$

Step-by-step explanation:

A null hypothesis is a type of hypothesis that states that there is no difference between a particular parameter of a population whereas an alternative hypothesis states that there is a difference.

Given: p = Proportion of all marketing researchers who disapprove of the actions taken in the conflict of interest scenario.

n= 200

Sample proportion = $\hat{p}=\dfrac{109}{200}=0.545$

Claim : p>0.50

Null hypothesis: $p\leq0.50$

Alternative hypothesis: $p>0.50$
