At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total

of $7.25. To determine the cost of one pickle, Kevin is writing a system of equations. His first equation is shown: x + 2y = 3.25
Which of the following could be the second equation in his system of equations?
3x + 4y = 7.25

4x + 3y = 7.25

3x - 4y = 7.25

(3 + 4)x = 7.25​

Answer:

p + 2c = 3.25 Start with these two equations

3p + 4c = 7.25

p = -2c + 3.25 Solve for one variable

3(-2c +3.25) + 4c = 7.25 Substitute

-6c + 9.75 + 4c = 7.25

-2c = -2

c = 1

p + 2(1) = 3.25 Substitute

p + 2 = 3.25

p = 1.25

A bag of chips costs $1

A pickle costs $1.25

Given fx ( ) = 2x 2 + 4 f 2 , determine ( ) f −1 and () .
TEA [102]

Answer:

<h2>12 and 6</h2>

Step-by-step explanation:

The equation is not properly formatted presumably here is the format.

Given

f(x) = 2x^2 + 4

determine f(2) , and f(−1).

So we are expect to perform substitution operation and return an answers for values of x= 2 and x= -1

1. When x= 2 we have

f(2) = 2*2^2 + 4\\\\f(2)= 2*4+4\\\\f(2)= 8+4\\\\f(2)= 12

2. When x= -1 we have

f(-1) = 2*-1^2 + 4\\\\ f(-1)= 2*1+4\\\\ f(-1)= 2+4\\\\ f(-1)= 6

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer:

1) shifts f(x) 4 units down  = g(x) = 2x-10

2) stretches by factor 4    =  g(x) = 8x-24

3) shifts f(x) 4 units right   =  g(x) = 2x-14

4) compresses by factor 4 =  g(x) = 8x-6

Step-by-step explanation:

1)<em> When we have to move the function down by 4 units, subtract the whole function by -4, that is y -4.</em>

Thus, f(x) becomes  g(x) = 2x-6-(4) = 2x-10

2) <em>When the function is stretched away from x axis, it means in Y direction.</em>

<em>  Thus, when stretched 4 units in Y direction, the function becomes 4(f(x))</em>

 =  g(x) = 4(2x-6) = 8x-24

3)<em>When we have to move the function right by 4 units, replace x with (x-4) in the function.</em>

Thus, f(x) becomes  g(x) = 2(x-4)-6 = 2x-8-6 = 2x-14

4) <em>When the function is stretched towards y axis, it means in X direction.</em>

<em>  Thus, when compressed 4 units in X direction, replace the x by 4x.</em>

 =  g(x) = 2(4x)-6 = 8x-6
