Answer:

x=−5 and y=−1

Step-by-step explanation:

Let's solve your system by substitution.

y=2x+9;y=−x−6

Step: Solvey=2x+9for y:

y=2x+9

Step: Substitute2x+9foryiny=−x−6:

y=−x−6

2x+9=−x−6

2x+9+x=−x−6+x(Add x to both sides)

3x+9=−6

3x+9+−9=−6+−9(Add -9 to both sides)

3x=−15

−15

(Divide both sides by 3)

x=−5

Step: Substitute−5forxiny=2x+9:

y=2x+9

y=(2)(−5)+9

y=−1(Simplify both sides of the equation)

Hope this helps!

A turtle is 20 5/6 inches below the surface of a pond. It dives to a depth of 32 1/4 inches. What was the change in the turtles

Lana71 [14]

Alrite, so their change is just their difference, namely 32 1/4 - 20 5/6.

let's change those to "improper" fractions first.

$\bf 20\frac{5}{6}\implies \cfrac{20\cdot 6+5}{6}\implies \cfrac{125}{6}
\\\\\\
32\frac{1}{4}\implies \cfrac{32\cdot 4+1}{4}\implies \cfrac{129}{4}\impliedby \textit{let's use an LCD of \underline{12}}\\\\
-------------------------------\\\\$

$\bf \cfrac{129}{4}-\cfrac{125}{6}\implies \cfrac{(3\cdot 129)+(2\cdot 125)}{12}\implies \cfrac{387-250}{12}\implies \cfrac{137}{12}
\\\\\\
\textit{hmmm 12 goes into 137, 11 times, thus}\quad \boxed{11\frac{5}{12}}
\\\\\\
\textit{because}\qquad \cfrac{11\cdot 12+5}{12}\implies \cfrac{132+5}{12}\implies \cfrac{137}{12}$

When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is tak

ddd [48]

Answer:

<h3>"When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is taken, then the distribution of is based on the <u> "t" </u>distribution</h3>

Step-by-step explanation:

Given that "When constructing a confidence interval for a population mean, if a population is normally distributed and a small sample is taken, then the distribution of is based on the "<u>t"</u>distribution."

Because the given sample size is smaller so we have to use the "t" distribution for constructing the confidence interval for a given population

A line, y = mx + b, passes through the point (1, 6) and is parallel to

docker41 [41]

Answer:

Step-by-step explanation:

Let the line to be found be Line 2

Given:

Line 1 :

y = 4x + 6

Since y = mx + b

We can substitute and find that the slope of Line 1 is 4

Therefore slope of Line 2 = (4)

Line 2:

Point - (1,6)

Slope - 4

Therefore: 6 = (4)(1) + b

So equating it we get : b = 2
