write the equation of the line, in standard form, that is perpendicular to y=3x-2 and passes through (-7,2)

34kurt

Answer:

x+3y=-1

Step-by-step explanation:

y=3x-2 so m=3 old slope

the new slope must be -1/3 (opposite reciprocal of the old slope).

y-y0=m*(x-x0)

y-2=-1/3*(x-(-7))

y-2=-1/3x-1/3*7

y-2=-1/3x-7/3

3y-6=-x-7

The standard form for linear equations in two variables is Ax+By=C.

x+3y=6-7

x+3y=-1

Please help me?!<br> I need help!?

Olin [163]

Answer:

Area = 6.25 $\pi$ ft^2

Step-by-step explanation:

Area = $\pi \\$ $r^{2}$

The diameter is 5 feet. That makes the radius 2.5 feet

Area = $\pi \\$ $r^{2}$

Area = $\pi \\$ $2.5^{2}$

Area = 6.25 $\pi$ ft^2

What to the tenth power can get you 300

OLEGan [10]

Answer:

1.7689 (rounded to 4 decimal places)

Step-by-step explanation:

Let the number we are seeking be "x", thus we can write the equation as:

$x^{10}=300$

Since we have raised "x" to the "10th power", to get "x" back again, we need to take 10th root. Same goes for right side, we take 10th root of 300. We will get our answer. The process shown below:

$x^{10}=300\\\sqrt[10]{x^{10}} =\sqrt[10]{300} \\x=\sqrt[10]{300} \\x=1.7689$

hence, 1.7689 raised to 10th power will give us 300

A student is solving the problem x^2 + 10x+ ___ = 16 + ___ by the method of completing the square. What number should the studen

kvv77 [185]

Answer:

I believe it could be any number because:

let y=any number

x^2+10x+y=16+y

x^2+10x+y-y=16+y-y

x^2+10x=16

you can add any number to both side and not change the solution.
