Answer:

Perpendicular

Step-by-step explanation:

Parallel lines are lines which do not intersect and their equations have the same slope.

Perpendicular lines are lines which intersect at 90 degree angles and their equations have slopes which are the negative reciprocal of each other. If the slope is 2 then the negative reciprocal would be -1/2.

To determine which this pair of equations is compare their slopes from slope intercept form.

y= 7/3 x +3                                        12x + 28y = 40 becomes y = -3/7 x + 10/7

The slope is 7/3.                                The slope is -3/7.

These are negative reciprocals of each other. The lines are perpendicular,

Find the coordinates of the vertex of the following parabola algebraically. Write your answer as and x,y point
Likurg_2 [28]

The equation of the parabola in the vertex form is y =  (x - 3)^{2} - 5 with ( 3, -5) is the vertex of the parabola and 1 is the multiplier

In the above question, A parabolic equation is given as follows:

Y = x^2 - 6x + 4

The equation of the parabola in the vertex form is :

y = a (x - h)^{2} + k

Where a is a multiplier in the equation and (h,k) are the coordinates of the vertex

So, in order to obtain this form, we will use the method of completing square :

Y = x^2 - 6x + 4

y = x^{2} - 6x + (9 -9) + 4

y = (x - 3)^{2} + ( -9 + 4)

y =  (x - 3)^{2} - 5

where, ( 3, -5) is the vertex of the parabola and 1 is the multiplier

Hence, The equation of the parabola in the vertex form is y =  (x - 3)^{2} - 5 with ( 3, -5) is the vertex of the parabola and 1 is the multiplier

Suppose a club publishes a newsletter. Expenses are$.50 for printing and mailing each copy, plus$300 total for research and writ
luda_lava [24]

200 copies must be  sold

n= number od newsletters

0,50*n+300=2,00*n

300=1,5*n

Divide both sides by 1,5

200=n

0,50*200+300=2*200

100+300=400

400=400
