Answer:
D. a line graph
Step-by-step explanation:
Answer:
Step 2 because Richard multiply the powers of same base in denominator instead adding powers of same base.
Step-by-step explanation:
We are given that Richard simplified an expression in threes steps
We have to find the incorrect step in simplification of Richard
Step 1: all the exponent are multiplied by 3
![\frac{x^{-4}y^2}{yx^2\cdot x^2y^{-4}}^{3}=\frac{x^{-12}y^6}{y^3x^6\cdot x^6y^{-12}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-4%7Dy%5E2%7D%7Byx%5E2%5Ccdot%20x%5E2y%5E%7B-4%7D%7D%5E%7B3%7D%3D%5Cfrac%7Bx%5E%7B-12%7Dy%5E6%7D%7By%5E3x%5E6%5Ccdot%20x%5E6y%5E%7B-12%7D%7D)
Step 2:The exponents in the denominator are multiplied
![\frac{x^{-12}y^6}{y^3x^6\cdot x^6 y^{-12}}=\frac{x^{-12}y^6}{x^{12}y^{-9}}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-12%7Dy%5E6%7D%7By%5E3x%5E6%5Ccdot%20x%5E6%20y%5E%7B-12%7D%7D%3D%5Cfrac%7Bx%5E%7B-12%7Dy%5E6%7D%7Bx%5E%7B12%7Dy%5E%7B-9%7D%7D)
Step 3:The exponents of the same base are subtracted during division
![\frac{x^{-12}y^6}{x^{12}y^{-9}}=x^{-12-12}y^{6+9}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-12%7Dy%5E6%7D%7Bx%5E%7B12%7Dy%5E%7B-9%7D%7D%3Dx%5E%7B-12-12%7Dy%5E%7B6%2B9%7D)
![=x^{-24}y^{15}](https://tex.z-dn.net/?f=%3Dx%5E%7B-24%7Dy%5E%7B15%7D)
Richard makes mistake in step 2 when we multiply then power of same base should be added but Richard multiply the powers of same base in denominator.
Answer: y=17
Explanation:
Notice that every time x decreases by 2, y increases by 8, and every time x decreases by 1, y increases by 4. That mean when x = 0, y = 5+4+4+4=17
Answer:
1200 L
Step-by-step explanation:
2/3 of the tank is removed, so 1/3 of the tank is left. This is equal to 400 L.
1/3 V = 400 L
V = 1200 L
The volume of the tank is 1200 L.
Answer:
b. The greater the number of independent variables measured, the more difficult it is to interpret higher-order interactions.
