Answer:
Let's start with part B. if it was originally 10 cm tall and it goes up 0.5 cm. each day, then we know that to go up one cm it needs two days. With that information we can say that 8*2 = 16. So it needs 17 days to go up 8.5 cm which would make it 18.5 cm tall.
Step-by-step explanation:
f(x) = 0.5x + 10
0.5x + 10 = 18.5
0.5x = 18.5 - 10
0.5x = 8.5
x = 8.5/0.5
x = 17 days
Answer: An equations is a number, a variable, or a combination of numbers and variables and operational symbols. An equation is made up of two expressions connected by an equal sign.
Example Expression: 8x+5y-3x-5
Example Equation: 5x-4=x
Hope this helps a little bit:)
Combining like terms would be defined as multiplying each term in a set of parentheses by the number outside of the parentheses.
Answer:
Step-by-step explanation:
The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.
m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.
So the inverse slope would be -1.
Answer:The approximate square root is 2.23
Step-by-step explanation:√ 5 = 2.23
Thus: 2.23 x 2.23 = 5
