tatyana61 [14]

Answer:

$13$

Step-by-step explanation:

Donna's Rate is $R$

Rico's Rate is $R+2$

$\frac{R}{R+2}=\frac{2}{3}$

Cross-Multiply

$2(R+2)=32$

$2R+4=3R$

$4=R$

Donna's Rate is $R=4$

Rico's Rate is $R+2=6$

$\frac{6(130)}{60} = \frac{130}{10}=13$

Verify the property: a ×( b+c ) = ( a×b ) + ( a×c ) by taking a = 3/5 , b = -2 , c = 10/13

Ivanshal [37]

Answer:

This is the distributive property

Step-by-step explanation:

You use the distributive property to allocate a number outside of the parentheses to inside the parentheses.

For this example, they distributed a to both b and c making it a*b + a*c

This will result in the same answer:

3/5(-2 + 10/13) = 3/5*-2 + 3/5*10/13

3/5(-1.23..) = -6/5 + 30/65 (..= approx)

approximately- 0.74 = -0.74

Answer:

C. F(x) = 4x² + 1

Step-by-step explanation:

→The function F(x) shifted 1 unit upwards, meaning there needs to be a 1 being added to the function.

→In addition, the function F(x) has grown narrower, compared to the function G(x). This is from the absolute value of a number being greater than 1, which is being multiplied.

<u>This means the correct answer should be "C. F(x) = 4x² + 1."</u>
