Answer:
340.65
Step-by-step explanation: Add 84.79+44.75+18.66=148.2
148.2-$488.85= 340.65
For linear, the y-differences are equal. An example is the total cost of buying a single type of item.
Quadratic - the 2nd differences are equal,. Example: path of a kicked ball
Cubic - the 3rd differences are equal. Example: modeling the shapes of vases or curved designs
Exponential - the y-ratios are equal. Example: growth of bacteria
Answer:
1 Simplify 75\times 875×8 to 600600.
600\div 25
600÷25
2 Simplify 600\div 25600÷25 to 24
24
Step-by-step explanation:
Answer:
y = 3/4x+8
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (8-2)/ (0- -8)
= (8-2)/(0+8)
= 6/8
3/4
The y intercept is 8 The y intercept is where x =0
The equation of a line is
y = mx+b where m is the slope and b is the y intercept
y = 3/4x+8
Answer:
x = -4
Step-by-step explanation:
Square both sides:
The square root and the square will cancel to leave simply the argument within the square root:
-5 - 2x = -1 - x
Now simply isolate the variable x:
x = -5 + 1 = -4
Check to see if x = -4 will work:
This works, so we know that x = -4 is a solution.
Hope this helps!
