Ok, so the function form is y = a * bx.
Substitute in the values:
750 = a * b5
and
48 = a * b2
Then divide the two equations:
750/ 48 = (a * b5) / (a * b2)
So:
15.625 = b3
Take the cube root of both sides:
2.5 = b
Now, substitue b into one of the equations (the one with 48 has smaller numbers and is easier to work with.)
48 = a * 2.52
Simplify.
48 = a * 6.25
Divide both sides by 6.25
7.68 = a
Now substitute in a and b to write the exponential function:
y = 7.68 * 2.5x
Answer: a=3, b=1
A parallelogram have its opposite sides equal and parallel.
Step-by-step explanation:
SO, the quadrilateral WXYZ have its opposite sides equal as its a parallelogram.
From the given figure the side XY= WZ and XW= YZ, which gives two equations i.e
Equation 1 is 3a-4=a+2 and Equation 2 is b+1=2b
Solving Equation 1 Solving equation 2
3a-a = 2+4 2b-b = 1
2a = 6 b=1
a = 3
So, by solving the two equations a=3 and b=1.
4. Change the sign of the integer
Y = -5x -5
To check, we can insert 0 for y and -1 for x
0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0
So yes, the equation is correct
