What is y in the first line if the line passing though (-1,y) and (1,0) perpendicular to the line passing (8,4) and (-1,1) ?

.

Step-by-step explanation:

A line that goes through and where would have a slope of .

The slope of the line that goes through and would thus be:

.

Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is .

Thus, if and denote the slope of the first and second lines in this question, since the two lines are perpendicular to one another. Since , the slope of the first line would be:

.

Given that the first line goes through the point , the point-slope equation of that line would be:

.

.

Substitute in to find the -coordinate of the point in question:

.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
