Answer:
C. The functions have the same y-intercept
Step-by-step explanation:
In slope intercept form, y = mx + b, b represents the y-intercept, and in the first function the y-intercept is 10.
The y-intercept is when x = 0, and in the chart, when x equals 0, y equals 10.
10 = 10, so they have the same y-intercept.
Answer:
C. 4
Step-by-step explanation:
All other answer choices involve the variable 'b' and/or are tied to it in some way. The sole number 4 has no connection to the variable b, therefore it is C. 4.
The evaluate expression is 8
Answer:
9g/mL
Step-by-step explanation:
The density of something is mass/volume and the density of something never changes, no matter how much or how little there is of it.
We know that the mass of Cu (copper) is 45g and its volume is 5.0mL.
density = 45g/5.0mL
Plug that into a calculator and you'll get your answer.
