Show whether each equation has one solution, infinitely, many solutions or no solutions: 2x+7=-8x-9+10x

Step-by-step explanation:

Step 1: Collect the like terms

2x+7 = -8x-9+10x

2x+7 = 2x-9

Step 2: Cancel equal terms of both sides of the equation

2x+7 = 2x-9

7 = -9

Result: The statement is false and there is no solution as 7 is not equal to -9.

I hope this helped ! ;)

answer: c i think

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
