7x-6y=18 14x+9y=-27?

Effectus [21]

Answer: Hope this helped(tried my best thinking what the question was asking)

x=0

y=-3

Step-by-step explanation:

(Im going to add and subtract)

Add:

14x-12y=36

14x+9y=-27

28x-3y=9

Subtract:

-14x+12y=-36

14x+9y=-27

21y=-63

y=-3 (substitute in first equation)

7x+18=18

7x=0

x=0

y=-3 and x=0

Grandma Gertrude's Chocolates, a family owned business, has an opportunity to supply its product for distribution through a la

igor_vitrenko [27]

<h2>Answer with explanation:</h2>

Given : Sample size : n = 36

Significance level for 90% confidence : $\alpha: 1-0.9=0.1$

Sample mean : $\overline{x}=0.60$

Standard deviation : $\sigma=0.08$

By using standard normal table for t-values,

Critical t-value : $t_{(n-1, \alpha/2)}=t_{(35,\ 0.05)}=1.690$

Thus, the correct value of t to construct a 90% confidence interval for the true mean percentage of cacao : $t_{(35,\ 0.05)}=1.690$

Confidence interval for population mean :

$\overline{x}\pm t_{(n-1, \alpha/2)}\dfrac{\sigma}{\sqrt{n}}\\\\=0.60\pm(1.69)\dfrac{0.08}{\sqrt{36}}\\\\=0.60\pm0.0225333333333\\\\\approx0.60\pm0.023\\\\=(0.60-0.023,\ 0.60+0.023)=(0.577,\ 0.623)$

Hence, A is the correct answer .

Function g(x) = 2x2-8

irga5000 [103]

Answer: Confusing.

If it's f(x) is 2 times 2 minus 8, it's a horizontal line at y-4.

If it's f(x) is 2x 2-8

It's handy to use a graphing calculator.

Step-by-step explanation:

Be sure to clarify what the equation means

Thanks to Desmos for the graphs.

As you can see, the numbers could represent a lot of different things-- especially when 'x' can be a variable -- or confused with the multiplication sign.
