CAN SOMEBODY HELP WITH THIS QUESTION ASAP​

Answer:

The rectangles are not similar

Step-by-step explanation:

In order to check whether they are similar, we need to take the ratio of their similar sides and ensure they are equal to a constant k.

Hence;

AB/PL = AD/LM = k

32/26 = 18/12 = k

16/13 = 9/6 = k

Since the scale factor is not the same, hence the rectangles are not the same.

Which function has the same y-intercept as the function y equals 2/3 x - 3​
aleksley [76]

We have the function y = \frac{2}{3} x -3 and we want to find a function that has the same y-intercept than the previous function.

First, let's find the y-intercept by subtituting 0 for 'x'.

y = \frac{2}{3} (0) -3 = -3

Now that we found that y-intercept =-3, any lineal function of the type: y = ax - 3 will have the same y-intercept. Where 'a' can take all the real values.

Also, any quadratic function of the type: y=ax^{2} + bx - 3 will have the same y-intercept. Where 'a' and 'b' can take all the real values.

What percent of 33 is 96
Nataly_w [17]
<span>96/x=100/33
(96/x)*x=(100/33)*x       - we multiply both sides of the equation by x
96=3.0303030303*x       - we divide both sides of the equation by (3.0303030303) to get x
96/3.0303030303=x 
31.68=x 
x=31.68

now we have: 
33% of 96=31.68
