Answer:

Step-by-step explanation:

<em>Replace it with y</em>

<em>Exchange the values of x and y</em>

<em>Solve for y</em>

<em>Subtracting 1 from both sides</em>

<em>Dividing both sides by 2</em>

<em>Replace it by </em>
So,

Answer:
Step-by-step explanation:
Actually Welcome to the Concept of the linear equations..
Here given value of x= 5 and y =1 , so we get as,
5a + b = 38 and 5b - a = 8
so, now we multiply equation no. 2 by 5 all over.
==> 25b - 5a = 40....(1)
hence adding new equation and equation no. 1
26b = 78
b = 78/26
hence b = 3 , and a = 7
Answer:Tap for more steps... By the Sum Rule, the derivative of x 4 + 3 x 2 x 4 + 3 x 2 with respect to x x is d d x [ x 4] + d d x [ 3 x 2] d d x [ x 4] + d d x [ 3 x 2]. Differentiate using the Power Rule which states that d d x [ x n] d d x [ x n] is n x n − 1 n x n - 1 where n = 4 n = 4.

Answer:
Step-by-step explanation:
Similar figures have the same shape but the same size.
Moving from left to right:
The first figure is similar because it is rotated
The second figure is not similar because of shape
The third figure is not similar because of different ratio the ratio for the figure above is 3/5 or 0.6, while this figure is 12/15 or 0.8
The fourth figure is not similar because of ratio, but it is still a rectangle
The fifth figure is not similar because of shape
The last figure is similar because the ratio is the same with 6/10 or 0.6
