That answer would be (2)+3(3)+8(4) which would give you 2+9+32. If you add all of that together you get 43

i've asked this 5 times already if y'all answer or points and answer with nmo explanation i am going to download photomath
mina [271]

Answer:

Rahm: 0.8

Bain: 1.2

Step-by-step explanation:

For this, they ask for the rate of change or slope. To find slope you can use slope formula to get your slope/rate of change.

Steps for Rahm:

We can take points (10,8) and (20,16) and find the slope with the following formula: \frac{y^2-y^1}{x^2-x^1}

\frac{16-8}{20-10} = 0.8

This is the rate of change for Rahm

Steps for Bain:

Take the points (5,6) and (11,13.2) and plug them into the Slope Formula:

\frac{13.2-6}{11-5} = 1.2

Therefore, Bain hiked faster than Rahm for he had the higher rate of change compared to Rahm.

Richard simplified an expression in three steps, as shown:
soldi70 [24.7K]

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}}

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}}

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}

=x^{-24}y^{15}

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.
