f(x) =2x+4 translate 7 units left
Answers
Answer:
[tex]f'(x) = 2x - 10[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x + 4[/tex]
Required
Translate 7 units left
When a function f(x) is translated b units to the left, the resulting function is:
[tex]f'(x) = f(x-b)[/tex]
In this case:
[tex]f(x) = 2x + 4[/tex]
[tex]b = 7[/tex]
[tex]f'(x) = f(x-b)[/tex] becomes
[tex]f'(x) = f(x - 7)[/tex]
Calculating [tex]f(x-7)[/tex]
[tex]f(x-7) = 2(x-7)+4[/tex]
[tex]f(x-7) = 2x-14+4[/tex]
[tex]f(x-7) = 2x-10[/tex]
So:
[tex]f'(x) = 2x - 10[/tex]

What is the solution of 5/2x-7=3/4x+14
A. X=-6
B. X=6
C. X=8
D. X=12
Answers
Answer x=12
Step-by-step explanation:
5/2x-7=3/4x+14
+7. +7
5/2x=3/4x+21
-3/4x -3/4x
5/2-3/4=7/4x
7/4x=21. since there's a fraction on one side, multiply 4 with 21
7x=84
divide and you'll get x=12
[tex] \frac{5}{2} x(4) - 7(4) = \frac{3}{4} x(4) + 14(4) \\ 10x - 28 = 3x + 56[/tex]
Solve the equation for x-term.[tex]10x - 3x = 56 + 28 \\ 7x = 84 \\ x = \frac{84}{7} \\ x = 12[/tex]

Alex is tracking how many computers he can fix in an afternoon. He listed the number of computers fixed per hour in the following table: Hour (x) Number of Customers f(x) 1 4 2 8 3 12 Determine if these data represent a linear function or an exponential function, and give the common difference or ratio.
Answers
This is a linear function because there is a common difference of 4
⇒ 2nd answer
Step-by-step explanation:
- In the linear function there is a common difference between each two
consecutive data
- In the exponential function there is a common ratio between each two
consecutive data
- Lats check the data in the data in the table
(x) === 1 ⇒ 2 ⇒ 3
f(x) === 4 ⇒ 8 ⇒ 12
∵ x has consecutive numbers 1 , 2 , 3
∵ 8 - 4 = 4
∵ 12 - 8 = 4
∴ f(x) has a common difference 4
∵ 8 ÷ 4 = 2
∵ 12 ÷ 8 = 1.5
∴ f(x) has no common ratio
∴ The table represents a linear function with common difference 4
This is a linear function because there is a common difference of 4
A linear function passes through (-2, 12) and (4,0). What is the slope of the function?
Answers
Answer:
-2
Step-by-step explanation:
I actually just did functions in math at the end of last semester I offer you my condolences dude
The slope of the function that passes through two points (-2, 12) and (4,0) is -2
Slope of the function
Slope of the function is calculated by find the rate of change of y over rate of change of x.
The formula to fidn out the slope is
[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]
The function passes through two points (-2,12) and (4,0)
substitute the points and find out the slope of the fuction
(x1,y1) is (-2,12)
(x2,y2) is (4,0)
Substitute the values
[tex]slope =\frac{0-12}{4+2}=\frac{-12}{6} =-2[/tex]
The slope of the function that passes through two points (-2, 12) and (4,0) is -2

The final exam grade of a statistics class has a skewed distribution with mean of 79 and standard deviation of 8.2. If a random sample of 35 students selected from this class, then what is the probability that average final exam grade of this sample is between 76 and 82
Answers
Answer:
0.9696
Step-by-step explanation:
Given that:
Mean, m = 79
Standard deviation, s = 8.2
Sample size, n = 35
Probability that final exam grade of the sample is between 76 and 82
P(76 < x < 82)
P(x < 82) - P(x < 76)
Using the relation :
Z = (x - m) / (s/sqrt(n))
s / sqrt(n) = 8.2/sqrt(35) = 1.3860529
P(x < 82) - P(x < 76)
P[(82 - 79) / 1.3860529] - P[(76 - 79) / 1.3860529]
P(Z < 2.1644) - P(Z < - 2.1644)
Using the Z probability calculator :
0.98478 - 0.015217
= 0.969563
Hence, probability = 0.9696

The base of a triangle is....
Answers
Answer:
[tex]a=49[/tex]
Step-by-step explanation:
You would solve this the same way you would with any other triangle problem. You will plug in for the base and the height in this formula [tex]a=\frac{1}{2}bh[/tex].
[tex]a=\frac{1}{2}bh\\a=\frac{1}{2}(\sqrt{343})(\sqrt{28})[/tex]
Now we will multiply the two radicands.
[tex]a=\frac{1}{2}\sqrt{9604}[/tex]
For this we will split the 9604 into 49 and 196.
[tex]a=\frac{1}{2}\sqrt{49}\sqrt{196}[/tex]
Now we just take the square roots of those two and since they're perfect squares they'll be whole numbers.
[tex]a=\frac{1}{2}(7)(14)[/tex]
Next we just multiply everything together.
[tex]a=49[/tex]

Answers
Answer:
t = 8w + w/2
Step-by-step explanation:
Given that :
Weight of bird = w
Amount of water consumed = 8*w = 8w
Amount of food ate = 0.5*w = 1/2w
Hence, the combined weight of water and food (t) consumed by the humming bird :
t = amount of water consumed + amount of food ate
t = 8w + w/2

Simplify. 1+i/1-I + 1/ 1 + i. if i^2 = -1
Answers
I guess you mean
(1 + i ) / (1 - i ) + 1 / (1 + i )
in which case, notice that the denominator of both fractions are conjugates of one another. Combine the fractions by multiplying either fraction by the appropriate conjugate:
[(1 + i ) / (1 - i ) • (1 + i ) / (1 + i )]+ [1 / (1 + i ) • (1 - i ) / (1 - i )]
In either denominator, we have a difference of squares:
(1 + i ) (1 - i ) = 1² + i - i - i ² = 1² - i ² = 1 + 1 = 2
→ (1 + i )² / 2 + (1 - i ) / 2
→ ((1 + i )² + (1 - i )) / 2
Expand the numerator:
(1 + i )² + (1 - i ) = (1² + 2i + i ²) + 1 - i = 1 + 2 - 1 + 1 - i = 3 - i
and so
(1 + i ) / (1 - i ) + 1 / (1 + i ) = (3 - i ) / 2
