The sum of two integers is 74. The larger is 26 more than twice the smaller. Find the two integers.

1 answer:

7 0

To find the answer,we can set up two equations:

Let the integer be x and y seperately,and x be the larger number:

x+y=74
y=74-x....(1)

x-2y=26...(2)

Put (1) into (2):

x-2(74-x)=26
x-148+2x=26
3x=26+148
x=174/3
x=58

Put the above answer into (1):

y=74-58
y=16

Therefore,the answer is x=58, y=16.

Hope it helps!

If f(x)=4x^2 and g(x)=x+1, find (fog)(x)

iren [92.7K]

Answer: The value of $(f_\circ g)(x)$ is $4(x+1)^2$ .

Step-by-step explanation:

Given: $f(x) = 4x^2 \text { and } g(x) = x+1$

To find: $(f_\circ g)(x)$

As we know it is composition function which means that g(x) function is in f(x) function.

So we have

$(f_\circ g) (x) = f[g(x)]$

$\Rightarrow( f_\circ g)(x)= f(g(x)) = 4(g(x))^2$

Now substitute the value of g(x) we get

$(f_\circ g)(x)= 4(x+1)^2$

Hence, the value of $(f_\circ g)(x)$ is $4(x+1)^2$ .

Determine the equation of the linear function that generates the following table of values.

Mashutka [201]

Answer:

y = -19x + 14

Step-by-step explanation:

For each increase of x by 1, y decreases by 19, giving us -19x. When x = 0, y = 14, therefore, y = -19x + 14

What is the problem for this Problem?

ratelena [41]

Answer:

Negative: (-∞,-3] and [1/2,-∞)

Positive: [-3,1/2]

Step-by-step explanation:

The derivative is the instantaneous rate of change at any given point for a function. Given this we know that anywhere the function is in the positive or negative direction, the derivative will also be in the positive or negative direction. We also know that wherever there is a peak or a trough, there will be no slope and it signifies a change in direction. For this function, this means the direction changes at -3 and 1/2.
