Evaluate the expression: −(8 − 12) + 60 + (−4)2.

The constraints that describe the system of inequalities in this problem are given as follows:

The first step toward obtaining the constraints is defining the variables, as follows:

Apex feels that the ads must reach at least 37 million women, hence, for the amounts of each event, the constraint is given as follows:

7x + 2y ≥ 37.

They also want to reach at least 32 million men, hence the constraint is given as follows:

4x + 12y ≥ 32.

The reaches are already given in millions of people, hence the millions don't need to be inserted into the equations.

The value of the functions defined in the piecewise function f(1) - f(-7) is 4

From the question, we have the following piecewise function that can be used in our computation:

f(x) = | x + 8| - 9         if x ≤ -4

         -x² - 3x             if  -4 < x ≤ 1

         2x + 7               if  x > 1

So, we have the expression to be

f(1) - f(-7)

In the function f(1), we have the x value to be

x = 1

This x value is at the domain -4 < x ≤ 1

So, we make use of

f(x) = -x² - 3x

Substitute 1 for x in f(x) = -x² - 3x

f(1) = -(1)² - 3(1)

Evaluate

f(1) = -4

In the function f(-7), we have the x value to be

x = -7

This x value is at the domain x ≤ -4

So, we make use of

f(x) = |x + 8| - 9

Substitute -7 for x in f(x) = | x + 8| - 9

f(-7) = |-7 + 8| - 9

Evaluate

f(-7) = -8

Recall that

f(1) - f(-7)

So, we have

f(1) - f(-7) = -4 - -8

This gives

f(1) - f(-7) = 4

Hence, the value of f(1) - f(-7) is 4

The height of the cylindrical piece of pure gold with density and mass of 19.32 g/cm³ and 1699.48g, having a radius of 2cm is 7cm.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )

Also, density is expressed mathematically as;

p = m / v

Given that;

First, we determine the volume of the cylinder.

Density = Mass / Volume

Volume = Mass / Density

Volume = 1699.48g / 19.32g/cm³

Volume = 87.9648 cm³

Next, we determine the height.

V = π × r² × h

87.9648 = 3.14 × (2)² × h

87.9648 = 3.14 × 4 × h

87.9648 = 12.56 × h

h = 87.9648 / 12.56

h = 7cm

Therefore, the height of the cylinder is 7cm.

The remaining amount of salt that Tom needed to pour was 67.59 grams.

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

The group's total number of items decreases or becomes lower when we subtract from it.

As per the given,

The total amount that Tom needs to pour = 84.99 grams

Amount poured = 17.4 grams

Remaining = 84.99 grams - 17.4 grams = 7.59 grams

Hence "The remaining amount of salt that Tom needed to pour was 67.59 grams".

Answer:

2 7/15 miles

Step-by-step explanation:

1 4/5 = 1 + 4/5 = 5/5 + 4/5 = (5+4)/5 = 9/5

Then:

1 4/5 + 2/3 = 9/5 + 2/3

9/5 = 27/15

2/3 = 10/15

Then:

9/5 + 2/3 = 27/15 + 10/15 = (27+10)/15

= 37/15

37/15 = 30/15 + 7/15 = 2 + 7/15

The value of the given composite function f(g(7)) will be -9 for the given data.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given,

f(1)=7

Take the g function on both sides

g(f(1)) = g(7)

Since, g(7) = 11

Thus, Take f function on both sides,

f(g(7)) = f(11)

Since,f(11)=-9

Thus,f(g(7)) = -9

Hence "The value of composite function f(g(7)) is -9".

Answer:

x - 9y = -45

Step-by-step explanation:

y = 1/9 x + 5  Multiply all the way through by 9 to clear the fraction

9y = x + 45   -9y from  both sides

0 = x - 9y + 45  Subtract 45 from both sides

-45 = x  - 9y  You can rewrite

x - 9y = --45

Answer:-2

Step-by-step explanation:

Step 1: Write this in slope-intercept form

y=mx+b

Step 2: Plug in the known values

m is the slope, x is the given x value, and y is the given y value

4=2(3)+b

Step 3: Solve for the y-intercept

the y-intercept is b, so all we need to do is solve for b

4=6+b

subtract 6 from both sides so that y is isolated

Answer: b=-2

The y-intercept is -2

The numbers represented by the statement are 17 and 10

Represent the larger number with x and the smaller number with y

So, we have the following representation from the question

x = 2y - 3

x + y = 27

Substitute x = 2y - 3 in the equation x + y = 27

So, we have the following representation

2y - 3 + y = 27

Evaluate the like terms

3y = 30

Divide both sides by 3

y = 10

Recall that

x = 2y - 3

So, we have

x = 2 * 10 - 3
