For this, to figure that out plug in (-1, -1) into the x and y coordinates and solve:

-1=3(-1)+2\\ -1=-3+2\\ -1=-1

Since -1 = -1 is a true statement, (-1,-1) is a solution to this equation.

Answer:

\large\boxed{x=\dfrac{5}{4},\ y=\dfrac{15}{16}}

Step-by-step explanation:

\left\{\begin{array}{ccc}y=\dfrac{3}{4}x&(1)\\\dfrac{5}{2}x+2y=5&(2)\end{array}\right\\\\\text{Substitute}\ (1)\ \text{to}\ (2):\\\\\dfrac{5}{2}x+2\left(\dfrac{3}{4}x\right)=5\\\\\dfrac{5}{2}x+\dfrac{3}{2}x=5\\\\\dfrac{5+3}{2}x=5\\\\\dfrac{8}{2}x=5\\\\4x=5\qquad\text{divide both sides by 4}\\\\x=\dfrac{5}{4}

\text{Put the value of}\ x\ \text{to (1)}\\\\y=\dfrac{3}{4}\cdot\dfrac{5}{4}\\\\y=\dfrac{15}{16}

The dimensions of a standard tennis court are 36 ft. × 78 ft. with a net that is 3 ft. high in the center. The court is modified
Tema [17]

Answer:

Modified court is not similar to the standard court

Step-by-step explanation:

Given that :

Dimension of standard tennis court:

36ft by 78ft

Net height = 3 ft

Dimension of Modified Court :

27ft by 60ft

Net height = 3ft

To examine similarity :

We obtain the dilation factor for width and length :

(Standard court length / modified court length)

= 36 ft / 27 ft

= 4 / 3

Width :

Standard court width / modified court width)

= 78 ft / 60 ft

= 13 / 10

Since the dilation factor for the width and length are different, then we can conclude that the standard and modified court are not similar
