Rectangle A measures 12 cm by 3 cm. Rectangle B is a scaled copy of Rectangle A. Select all of the measurement pairs that could
Lana71 [14]

Answer:

A, D, and E

Step-by-step explanation:

The ratio between the sides of the rectangle is 12/3 = 4. In a scaled copy of rectangle A, the ratio between the sides needs to be 4 too.

For answer A the 6/1.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer B the 10/2 = 5, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer C the 13/4 = 3.25, it does not has the same ratio therefore is not a scaled version of rectangle A

For answer D the 18/4.5 = 4, has the same ratio therefore is a scaled version of rectangle A

For answer E the 80/20 = 4, has the same ratio therefore is a scaled version of rectangle A

What is the solution to the system of equations below? y = 1/4x + 2 and 3y = - 3/4x -6
lord [1]

Answer:

<h2>x = -8 and y= 0 → (-8, 0)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}y=\dfrac{1}{4}x+2&(1)\\3y=-\dfrac{3}{4}x-6&(2)\end{array}\right\\\\\text{Substitute (1) to (2):}\\\\3\left(\dfrac{1}{4}x+2\right)=-\dfrac{3}{4}x-6\qquad\text{use the distributive property}\\\\(3)\left(\dfrac{1}{4}x\right)+(3)(2)=-\dfrac{3}{4}x-6\\\\\dfrac{3}{4}x+6=-\dfrac{3}{4}x-6\qquad\text{subtract 6 from both sides}\\\\\dfrac{3}{4}x=-\dfrac{3}{4}x-12\qquad\text{add}\ \dfrac{3}{4}x\ \text{to both sides}\\\\\dfrac{6}{4}x=-12\qquad\text{multiply both sides by 4}\\\\6x=-48\qquad\text{divide both sides by 6}\\\\x=-8

\text{Put the value of x to (1):}\\\\y=\dfrac{1}{4}(-8)+2\\\\y=-2+2\\\\y=0
