Answer:

x = 3

Step-by-step explanation:

we know that if we have an original line and we are finding the perpendicular we know that the slope of the second line is gonna be the negative reciprocal of the first line and given that we know it must be perpendicular to the original line it will be heading downwards on the y axis with no slope so instead of y equals it will be x equals and we know that our x value of the point given is three so the answer is x = 3

Television sizes are measured on the diagonal Tony's television length is 42 inches and the television width is 31 inches what i

ValentinkaMS [17]

Answer:

52 in approx

Step-by-step explanation:

Given data

Length of TV= 42 in

Widht of TV= 31 in

Required

The diagonal of the TV

Applying the Pythagoras theorem

D^2= L^2+W^2

D= √L^2+W^2

D= √42^2+31^2

D=√1764+961

D=√2725

D=52.20 in

Hence the diagonal of the Tv is 52 in approx

NEED HELP WITH PART B

Sergeu [11.5K]

Answer:

y = -20x + 100

Step-by-step explanation:

As per your requirement For Part B, the solution is

The equation in slope-intercept form to model the relations is below:-

To reach 2 points on the graph the line passes through

lets use p1(0, 100), p2(1, 80)

now we will compute the slope:

$m = \frac{(y2 - y1)}{(x2 - x1)}$

$m = \frac{(80 - 100)}{(1 - 0)}$

= -20

and now use line equation in form point-slope:

y - y1 = m(x - x1)

y - 100 = -20(x - 0)

y = -20x + 100
