4x + 5y = 13

Is (2, 1) a solution to the given linear equation?

4(2) + 5(1)

8 + 5 = 13

(2, 1) is a solution to the given linear equation

Is (-3, 0) a solution to the given linear equation

4(-3) + 5(0)

-12 + 0 = -12

(-3,0) is not a solution to the given linear equation

Is (0, 1) a solution to the given linear equation

4(0) + 5(1)

0 + 5 = 5

(0, 1) is not a solution to the given linear equation

Hope this helps :)

1. The heights of two right prisms

RoseWind [281]

Answer:

They are not similar

Step-by-step explanation:

To determine whether the prism are similar we need to calculate their volumes

Volume of a prism = Base Area * Height

Volume of the first prism = 18ft *8 * 8ft

Volume of the first prism = 1152ft^2

Volume of the second prism = 30t * 15 * 15ft

Volume of the second prism = 6,750ft^2

Since the volumes are different, the prism are not similar.

$\bf \begin{array}{ccll}
hours&score\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
9&72\\
h&95
\end{array}\implies \cfrac{9}{h}=\cfrac{72}{95}\implies \cfrac{9\cdot 95}{72}=h$
