A.

variable  - an unknown value represented with a letter

B.  

coefficient  - a number written with a variable denoting how many

exponent - a number written on a base denoting how many times to multiply the base by itself

Hi there!

The answer is: 49

Because if we square a negative number, we get a positive number.

But there's a difference between (-7)² and -(7)².

(-7)² equals 49

-(7)²=-49

Hope this helps you!

Step-by-step explanation:

(45)(150)cos(30degrees)

The work done by the lawn mower is 3375 ft-lb.

The work done is equal to the force applied times the distance moved, but only in the direction of the force. In this case, the force is not horizontal, so we need to find the component of the force that is parallel to the ground.

The force applied to the lawn mower is 45 lb, and the angle between the force and the horizontal is 30°. We can use the sine function to find the component of the force that is parallel to the ground:

[tex]F_{parallel[/tex] = F * sin(theta) = 45 lb * sin(30°) = 22.5 lb

The work done is then:

W = [tex]F_{parallel[/tex] * d = 22.5 lb * 150 ft = 3375 ft-lb

Therefore, the work done is 3375 ft-lb.

Here is the solution in mathematical notation:

Work = [tex]F_{parallel[/tex] * d = F * sin(theta) * d = 45 lb * sin(30°) * 150 ft = 3375 ft-lb

Elena's total cost (C) is 5(9.98 + 24.99 + x)

Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:

Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)

C = 5(9.98 + 24.99 + x)

Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)

Answer:

  y -2 = 3/2(x -1)

Step-by-step explanation:

The slope formula tells you the slope:

  m = (y2 -y1)/(x2 -x1)

  m = (8 -2)/(5 -1) = 6/4 = 3/2

Using the first point in the point-slope form ...

  y -k = m(x -h) . . . . . line through (h, k) with slope m

  y -2 = 3/2(x -1)

Answer:

-2b

Step-by-step explanation:

since

|x| = x if x>0

and

|x| = -x if x<0

then it is -2b

The given modulus function at (b < 0) is written as (f(b) = -2b) and this can be determined by using the properties of the modulus function.

Given :

Expression  --  |2b| where b < 0

The following steps can be used in order to rewrite the given expression:

Step 1 - The generalized modulus function is given by:

f(x) = |x|

Step 2 - When x > 0 the above function becomes:

f(x) = x

Step 3 - When x < 0 the above function becomes:

f(x) = -x

Step 4 - So, the given expression is also a modulus function. The given modulus function at (b < 0) is written as:

f(b) = -2b

y is 5 times x plus 2

y=5x+2

The solution is, y=5x+2,  an equation that shows the relationship between the number of students photographed, x, and the total number of pictures on the memory card, y.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

She took 2 pictures to check that everything is working properly.

Now that it's picture day, she expects to take 5 pictures of each student.

now, we get,

the pattern is

y is 5 times x plus 2

Step-by-step explanation:

the numbers : x, y

x - y = 8

2y = x + 4

2y - 4 = x

we use the last equation in the first :

2y - 4 - y = 8

y - 4 = 8

y = 12

x = 2y - 4 = 2×12 - 4 = 24 - 4 = 20

the smaller number is 12.

The value of the smaller number will be 12.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The difference between two whole numbers is 8.

And, Twice the smaller number is 4 more than the larger number.

Now,

Let two numbers are x and y.

Where, x is larger number and y is smaller number.

Since, The difference between two whole numbers is 8.

Hence, We get;

⇒ x - y = 8

⇒ x = 8 + y  ..(i)

And, Twice the smaller number is 4 more than the larger number.

So, We get;

⇒ 2y = 4 + x  ..(ii)

Substitute the value of x from (i) in above equation, we get;

⇒ 2y = 4 + 8 + y

Solve for y as;

⇒ 2y - y = 12

⇒ y = 12

Thus, The value of the smaller number will be 12.
