write an equation of the line with the following information. Through (4,1) and perpendicular to y=1/3x +3
Yakvenalex [24]
Perpendicular means the two lines' slopes are negative reciprocal to each other. the slope of the given line is 1/3, therefore the slope of the perpendicular line is -3/1, which is -3
use the point-slope form: the given point is (4,1), so (y-1)=-3(x-4)
you can stop right here or you can write it into slope intercept form:
y-1=-3x+12
y=-3x+13

Answer:

x = 5

Step-by-step explanation:

Add the degrees of m<VUJ and m<JUT and make them equal to 175 since both angles exist with m<VUT.

17x - 3 + 17x + 8 = 175

34x - 3 + 8 = 175

34x + 5 = 175

34x = 170

x = 5

Answer:

The treatment decays by half each week.

Step-by-step explanation:

The decay function is given by:

y=a(1-r)^{t}

Here,

<em>y</em> = final value

<em>a</em> = initial value

<em>r</em> = decay rate

<em>t </em>= time

The decay function for one medications to treat dogs for fleas is:

F(x)=4\cdot (\frac{1}{2})^{w}

Here the decay rate is:

1-r=\frac{1}{2}\\\\r=1-\frac{1}{2}\\\\r=\frac{1}{2}

The treatment decays by half each week.
