Answer:

5\sqrt{2}

Step-by-step explanation:

h(x)=\sqrt{5x} \\\\then\\\\h(10)=\sqrt{5*10} = \sqrt{50} = \sqrt{25*2} = \sqrt{25}*\sqrt{2} = 5*\sqrt{2} = 5\sqrt{2}

Given the equation Y-4=3/4(x+8) in point-slope form, identify the equation of the same line in standard form
alisha [4.7K]

Answer:

3x-4y=-40

Step-by-step explanation:

Hi there!

We're given the equation of the line, y-4=3/4(x+8) in point-slope form (y-y_{1}=m(x-x_{1}), where (x_{1},y_{1}) is a point and m is the slope)

We need to convert y-4=3/4(x+8) into standard form (ax+by=c, where a, b, and c are integer coefficients; a CANNOT be 0, and CANNOT be negative).

So we need to get y-4=3/4(x+8) out of point-slope form

We can do this by converting the equation into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

to do this, we need to isolate y by itself in the equation

first, do the distributive property and distribute 3/4 on the right side

y-4=3/4x+6

add 4 to both sides

y=3/4x+10

now the equation is in slope-intercept form, but remember, we want it in standard form

x and y are on the same side in standard form, so let's subtract 3/4 x from both sides

-3/4x+y=10

however we aren't done; in standard form, the coefficients need to be integers (whole numbers), and a (the coefficient in front of x) CANNOT be negative

so let's multiply both sides by -4 to clear the fraction and change the sign of a

-4(-3/4x+y)=-4(10)

do the distributive property

<u>3x-4y=-40</u>

Hope this helps! :)

Help me on number 24 plss
chubhunter [2.5K]
The animal that shows the fastest change is the horse. The animal that shows that slowest rate of change is the mouse.
We can use graphs to find the rate of chabge by comparing. From using only the beginning and ending of the data, we would be finding the average rate of change over the specified period of time.
I think yes, my answers are reasonable.


I hope this helps :)
