f(x) = x − 7 and g(x) = x2 find f(g(−1))

Answer:

Answer is 3

Step-by-step explanation:

x/3-2x/1+3 =x-3/5

x/3-x/3 = x-3/5

0=x-3/5

0=x-3

3=x

sothat, x = 3 ans

Answer:

The inverse f-1(x) = ( x + 10)/2.

Step-by-step explanation:

f(x) = 2x - 10

Find x in terms of f(x):

2x = f(x) + 10

x = (f(x) + 10))/ 2

Replace x by the inverse f-1(x) and f(x) by x:

f-1(x) = (x + 10)/2.

Answer:

$95, $115, $135, $155

Step-by-step explanation:

If the first person gets x dollars:

the next person gets 20 more, so x + 20 dollars

the next person gets x + 40 dollars

and the last person gets x + 60 dollars

We add all these allocations together, and we get $500

x + (x + 20) + (x + 40) + (x + 60) = 500

Combine like terms

4x + 120 = 500

Subtract 120 on both sides

4x = 380

Divide by 4 on both sides

x = 95

So the first person gets $95.

The second person must get $115

The third must get $135

And the fourth must get $155

Checking our work:

95 + 115 + 135 + 155 = 500

Answer:

6/5

Step-by-step explanation:

To find the slope, we use the formula

m = ( y2-y1)/(x2-x1)

    = ( -7 - -1)/(-15 - -10)

    = (-7+1)/(-15+10)

    = -6/-5

[tex]\boxed {\boxed {\sf (3, \frac{7}{2}) \ or \ (3, 3.5)}}[/tex]

Step-by-step explanation:

The midpoint is the middle point of a line segment that bisects (splits into 2 equal parts) the line segment. When we calculate the midpoint, we basically find the average of the x-coordinate, then the average of the y-coordinates. The formula is:

[tex](\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the endpoints of the segment.

We are given the points (4,5) and (2,2). Match the value and the corresponding variable.

Substitute these values into the formula.

[tex](\frac{4+2}{2} , \frac{5+2}{2})[/tex]

Solve the numerators.

[tex](\frac{6}{2}, \frac{7}{2})[/tex]

Divide.

[tex](3, \frac{7}{2}) \ or \ (3, 3.5)[/tex]

The midpoint of the line segment is (3, 7/2) or (3, 3.5).

Answer:

7

Step-by-step explanation:

By the definition of alternate interior angle:

3x-2=2x+5

3x-2x=5+2

x=7

Note:if you need to ask any question please let me know.

Answer:

x = 7

Step-by-step explanation:

since these are alternating interior angles, these two expressions will be = to each other

2x+5=3x-2

subtract the 2x from both sides

5=x-2

add the 2 to both sides

7=x

The absolute value of a number returns the positive value of the given number. A real life situation that describes the scenario is:

"the point which a boy stands if the boy is standing 2.5 meters away from the 7.5 meters point."

Given that:

[tex]x = 5\ or\ x = 10[/tex]

An example of real life situation is as follows:

Calculate the point which a boy stands if the boy is standing 2.5 meters away from the 7.5 meters point.

Represent the point at which the boy stays with x. So, the situation is represented as:

[tex]|x - 7.5| = 2.5[/tex]

Remove absolute brackets

[tex]x - 7.5 = 2.5\ or\ x - 7.5 = -2.5[/tex]

Solve for x

[tex]x = 7.5+2.5\ or\ x = 7.5-2.5[/tex]

[tex]x = 10\ or\ x = 5[/tex]

Hence, the value of x is 5 or 10

Answer:

12,250

by dividing the 441000 by 36, I got the answer.

The population density of Miami, in people per square mile, in 2015 was 12,250

The given parameters are:

The population density of a place is the ratio of the population to the unit square area.

So, we have:

[tex]Density=\frac{Population}{Area}[/tex]

Substitute known values

[tex]Density=\frac{441000}{36}[/tex]

[tex]Density=12250[/tex]

Hence, the population density of Miami, in people per square mile, in 2015 was 12,250
