Percent error = (estimate - real)/(real) * 100
percent error = (78.25 - 75.50)/(75.50) * 100
percent error = 3.6%
Step-by-step explanation:
Matrix has 5 rows and 3 columns.
So it's order is 5x3.
Answer:
Remove 1 x-tile from both sides.
Remove 3 unit tiles from both sides.
Step-by-step explanation:
2x + 3 = x + 5
First we want all the variables on one side
Subtract x from each side so Remove 1 x-tile from both sides.
x+3 = 5
Now we need to get all the constants on the same side
Subtract 3 from each side so Remove 3 unit tiles from both sides.
x = 5-3
x=2
Answer:
x=-4 x=2
Step-by-step explanation:
y = x^2 + 2x - 8
Set equal to zero
0 = x^2 + 2x - 8
Factor
What two numbers multiply to -8 and add to 2
4 * -2 = -8
4+-2 = 2
0=(x+4) ( x-2)
Using the zero product property
x+4 =0 x-2 =0
x=-4 x=2
