Evaluate f(x) = 2x - 7 when x = 4.

Mathematics
1 answer:
gavmur [86]3 years ago

Answer:

x =  \frac{11}{2}  \\

Step-by-step explanation:

f(x) = 2x - 7

when x = 4

It means that equate f(x) to the value of x that's 4 and solve for x

That's

f(x) = 4

We have

2x - 7 = 4

<u>Add 7 to both sides of the equation</u>

2x  + 7 - 7 = 4 + 7 \\ 2x = 11

<u>Divide both sides by 2</u>

\frac{2x}{2}  =  \frac{11}{2}  \\

We have the final answer as

x =  \frac{11}{2}  \\

Hope this helps you

So here's the information we know:
Tanya bought 3 items
Tony bought 4 items
Tony's items were all 2.50 less than Tanya's

So, our equation should look like this:
3x = 4(x - 2.25)

(b)
3x = 4(x - 2.25)
3x = 4x - 9
-x = -9
x = 9

Tanya spent = 9 (x)
Tony spent = 6.75 (x - 2.25)

(c)
3(9) = 4((9) - 2.25)
27 = 36 - 9
27 = 27

or

Tanya: 3x = 3 (9) = 27
Tony: 4( x - 2.25) = 4(9-2.25) = 4(6.75) = 27

(d)
We can conclude that Tanya bought 3 items with a cost of $9 each, and Tony bought 4 items with a cost of $6.75 each. Both Tanya and Tony spent a total of $27.

Point N(7, 4) is translated 5 units up.
lutik1710 [3]

It is given in the question that

Point N(7, 4) is translated 5 units up.

And we have to find the coordinates of its image after this transformation.

Since the point translated up by 5 units, so the x coordinate remains same and we have to add 5 to y coordinate.

So the new coordinate after the transformation is

N'(7+5,4)&#10;\\&#10;N'(12,4)

And that's the required coordinate  after the given transformation .

Oksi-84 [34.3K]
Rents his place for $125 per day and his goal has to be in 5 days. Lets use 125 times 5 days then each chime sold is $12 and we need the number of chimes sold so we use "x" as our variable. Equation 125(5) + 12x = 3500. Hope this helps.
