Answer:

Step-by-step explanation:

The notation (f∘g)(1) means f(g(1)). We can first find g(1), then use that value as the argument to the f function.

g(1) = 2·1-6 = -4

f(-4) = -4(-4)+7 = 16+7 = 23

In the 1800s, wagon trains traveled west along the oregon trail. A wagon train traveled from missouri to wyoming in 1 2/3 months

strojnjashka [21]

Answer: 2 4/15 months

Step-by-step explanation:

From the question, we are informed that a wagon train traveled from Missouri to Wyoming in 1 2/3 months and from Wyoming to Utah in 3/5 month.

The number of months that it will take the wagon train to travel from Missouri to Utah will be:

= 1 2/3 + 3/5

The common lowest multiple is 15

= 1 10/15 + 9/15

= 1 19/15

= 1 + 1 4/15

= 2 4/15 months

It will take they train 2 4/15 months to travel from Missouri to Utah.

Find a point on the y-axis that is equidistant from the points (8, −8) and (1, 1).

artcher [175]

$\text{We know that any point on the y-axis is of the form (0, y),}\\
\text{because on y-axis we have x=0.}\\
\\
\text{So let (0, y) be the point on the y-axis that is equidistance from}\\
\text{the points }(8,-8) \text{ and }(1,1)\\
\\
\text{so using the distance formula, we have}\\
\\
\text{Distance between (0, y) and }(8,-8)=\text{Distance between (0,y) and }(1,1)\\
\\
\Rightarrow \sqrt{(0-8)^2+(y-(-8))^2}=\sqrt{(0-1)^2+(y-1)^2}$

$\Rightarrow \sqrt{64+(y+8)^2}=\sqrt{1+(y-1)^2}\\
\\
\text{Squaring both sides, we get}\\
\\
(\sqrt{64+(y+8)^2})^2=(\sqrt{1+(y-1)^2})^2\\
\\
\Rightarrow 64+(y+8)^2=1+(y-1)^2\\
\\
\Rightarrow 64+(y^2+16y+64)=1+(y^2-2y+1)\\
\\
\Rightarrow y^2+16y+128=y^2-2y+2\\
\\
\Rightarrow y^2+16y-y^2+2y=2-128\\
\\
\Rightarrow 18y=-126\\
\\
\Rightarrow y=\frac{-126}{18}\\
\\
\Rightarrow y=-7$

So the point on the y-axis that is equidistant from the points (8,-8) and (1,1) is: (0,-7)

I don't understand can someone help please.

Roman55 [17]

Answer: The point where the two graphed lines cross is the solution to the system of equations. (1, -1)

Step-by-step explanation:

The second equation is already in slope-intercept form y = x - 2

the slope is +1 (invisible coefficient of x) and the y-intercept is -2

y = mx +b

"m" is the slope (the coefficient of x) Positive slopes go up from left to right

"b" is the y-intercept, where the graphed line crosses the x-axis

Rewrite the first equation in slope-intercept form.

6x + y = 5 subtract 6x from both sides

<em>-6x</em> + 6x +y = -<em>6x</em> + 5 .( left side 6x + 6x =0 so "cancel")

y = -6x + 5

Then you know the slope and the intercepts

b = 5 so start with a point at +5 in the y-axis

m = -6 so from there go down 6 and over to the right 1 square and plot another point. Draw a straight line through the two points.

The point where the two graphed lines cross is the solution to the system of equations.

Your graph should look like the screenshot below.
