Answers

Answer:

25. 50 percent of 50 is 25 divided by 2.

Step-by-step explanation:

step1:Our output value is .50.

step2:we represent the unknown value with x

step3: from step1 above,.50=100%

step4: similarly,x=50%

step5: This results in a pair of simple equation:

.50=100%(1)

x=50%(2)

step6:by dividing equation 1 by equation 2 and noting that both the RHS(right hand side)of both equations have the same unite(%);we have

.50. 100%

____. = ____

x. 50%

step7: again,the reciprocal of both sides gives

x. 50

___ =. ___

50. 100

°x=0.25

therefore,50%of.50 is 0.25

Step-by-step explanation:

Isaiah earns $60 per week mowing lawns in the summer and shoveling driveways in the winter. He invested $220 in equipment. How long will it take him to earn $860? Find the equation and solve.

Answers

Answer:

18 weeks

Step-by-step explanation:

Create an equation where x is the number of weeks he works

60x - 220 will represent his profit, since he gets $60 a week but spent $220 in equipment.

Set this equal to 860, then solve for x, to find when he will earn $860

60x - 220 = 860

60x = 1080

x = 18

So, it will take him 18 weeks to earn $860

Solve 2x + 20 = 6x – 12*

Answers

Answer:

x = 8

Step-by-step explanation:

Given

2x + 20 = 6x - 12 ( subtract 2x from both sides )

20 = 4x - 12 ( add 12 to both sides )

32 = 4x ( divide both sides by 4 )

8 = x

=> 2x + 20 = 6x - 12

=> 20 + 12 = 6x - 2x

=> 32 = 4x

=> x =32/4

=> x = 8

Step-by-step explanation:

f(x)= 2x +6 , vertical shrink by a factor of 1/2

Answers

Answer:

g(x) = x+3.

Step-by-step explanation:

i hope this helps :D

When a function is shrunk vertically, the function has undergone a form of transformation.

The resulting function when [tex]f(x) = 2x + 6[/tex] vertically shrink by 1/2 is [tex]f'(x) = x + 3[/tex]

Given that:

[tex]f(x) = 2x + 6[/tex]

[tex]k = \frac 12[/tex] --- shrink factor

When a function is shrunk vertically, the rule of transformation is:

[tex](x,y) \to (x,ky)[/tex]

So, we have:

[tex]f'(x) = k f(x)[/tex]

The new function becomes

[tex]f'(x) = \frac 12 \times (2x + 6)[/tex]

[tex]f'(x) = x + 3[/tex]

Hence, when [tex]f(x) = 2x + 6[/tex] is vertically shrunk by 1/2, the new function is [tex]f'(x) = x + 3[/tex]

Answers

Answer:

k=−0.8

Step-by-step explanation:

Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)

Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)

(0.2)(3k) + (0.2)(1) = 0.6k + 0.2

(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k

New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k

Now we can combine like terms on the right side. (-0.4 and 0.2)

0.6k + 0.2 = 0.1k - 0.2

Now to get rid of k on one side, we can subtract 0.1k from the right side.

(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2

0.5k + 0.2 = -0.2

Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.

0.5k + (0.2 - 0.2) = (-0.2 - 0.2)

0.5k = -0.4

To get k by itself, we must divide both sides by 0.5.

(0.5k / 0.5) = (-0.4 / 0.5)

k = -0.8
