Answer:

(2,12)

Step-by-step explanation:

Original point is given as (2,-4) and the image point is give as (-3,6).

How do we get from x=2 to x=-3? We move left 5 units from x=2.

How do we get from y=-4 to y=6? We move up 10 units from y=-4.

So let's do this translation to the point (7,2)

Starting at x=7 we move left 5 units to get x=7-5=2.

Starting at y=2 we move up 10 units to get y=2+10=12.

The new point is (2,12)

2+x=15-7/8x how do you solve this?
uranmaximum [27]

Answer:2+x=15-7/8x

We move all terms to the left:

2+x-(15-7/8x)=0

Domain of the equation: 8x)!=0

x!=0/1

x!=0

x∈R

We add all the numbers together, and all the variables

x-(-7/8x+15)+2=0

We get rid of parentheses

x+7/8x-15+2=0

We multiply all the terms by the denominator

x*8x-15*8x+2*8x+7=0

Wy multiply elements

8x^2-120x+16x+7=0

We add all the numbers together, and all the variables

8x^2-104x+7=0

a = 8; b = -104; c = +7;

Δ = b2-4ac

Δ = -1042-4·8·7

Δ = 10592

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

x1=−b−Δ√2ax2=−b+Δ√2a

The end solution:

Δ−−√=10592−−−−−√=16∗662−−−−−−−√=16−−√∗662−−−√=4662−−−√

x1=−b−Δ√2a=−(−104)−4662√2∗8=104−4662√16

x2=−b+Δ√2a=−(−104)+4662√2∗8=104+4662√16
