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

Answer:
a line graph!
Step-by-step explanation:
have you ever seen the line graph emoji?
businesses usually use line graphs to show their profit over the year, month, or week!
It is kinda hard for people to answer interactive questions.so do what it says and make a line plot
Step-by-step explanation:
Length of rectangular park = 175 m
Breadth of rectangular park = 150 m
Perimeter of park = 2 x (length + breadth)
= 2 x (175 + 150)
= 2 x 325 = 650 m
Since, cost of fencing park per meter = = Rs. 12
Therefore, cost of fencing park of 600 m = 12 x 650 = Rs. 7,800
Square park=250m
Perimeter of the square park x 4
=250x4
=1000m
So, the cost of the fencing at the park would have a rate of 20 per m = 1000x20
=20000
