Use distributive property and multiply first
(85-65i+68i-52i^2)-(85-65i+51i-39i^2)
(85+3i-52i^2)-(85-14i-39i^2)  the subtraction sign applies to each part so
85+3i-52i^2-85+14i+39i^2  then add like terms
17i-13i^2

i^2 means i squared.

Walking path across the park is represented by the equation Y equals negative 2X -7. A new path will be built perpendicular to t
Genrish500 [490]

here the equation of path is -2x-7=y

let us find slope of this line by using y=mx+b

so slope m=-2

now new path is perpendicular to this path.

product of slopes of perpendiculars is -1

so slope of new path is 1/2

now it passes through (-2,-3) with slope 1/2

using y=mx+b to get value of b

-3=1/2(-2) +b

b=-2

plugging m=-1/2 and b=-2 in y=mx + b to get the final equation as

y=(-1/2) x -2 is the equation of new path

Put the following equation of a line into slope-intercept form, simplifying all
muminat

Answer:

y = 3/4 + 7

Step-by-step explanation:

you must put the equation into the form of y = mx + b

add 6x to both sides and put it in front of the 56

8y = 6x + 56

y must be by itself by x does not so we divide everything by 8

y = 6/8x + 7

we must simplify the fraction 6/8

y = 3/4x + 7
