Answer:
y = (3/4)x - 9
Step-by-step explanation:
The slope-intercept form of the equation of a straight line is y = mx + b.
Here we know x, y and m, but must find b.
Substituting 8 for x, -3 for y and 3/4 for m in the equation above results in:
-3 = (3/4)(8) + b, or (after multiplying all three terms by 4 to clear fractions):
-3 = 6 + b
Then b = -9, and the desired equation is y = (3/4)x - 9
Answer:
Ok take the root of both side and solve
So the Answer is x = 3i, - 3i Hope this helps :)

Answer:
Area = 396 units²
Step-by-step explanation:
Let's assume:
Length = 2c - 5
Width = 5c + 9
Perimeter = 2(L + W) = 106 units
Thus:
2[(2c - 5) + (5c + 9)] = 106
Find the value of c
2[2c - 5 + 5c + 9] = 106
2[7c + 4] = 106
14c + 8 = 106
14c = 106 - 8
14c = 98
Divide both sides by 14
c = 98/14
c = 7
✔️Area of the rectangle = Length × Width
Area = (2c - 5)(5c + 9)
Plug in the value of c
Area = (2×7 - 5)(5×7 + 9)
Area = (14 - 5)(35 + 9)
Area = (9)(44)
Area = 396 units²
