Well 4d is an algebraic term as it has a letter representing a number, 2m - 5 is also an algebraic term. 3 + 7 is a numerical expression as it is merely numbers. hope this helps

How do i graph x-y=-3
solmaris [256]
X - y = -3
y = x + 3.......slope = 1, y intercept = (0,3)

to find x int, sub in 0 for y and solve for x
x - y = -3
x - 0 = -3
x = -3....so the x intercept = (-3,0)

plot ur points (0,3) and (-3,0)......now start at (-3,0)....and since ur slope is 1, go up one, and to the right 1, and up 1, and to the right 1.....do this over as many times as needed and u should cross the y axis at (0,3)

Each year, Kipp raises money by participating in the Walk for Breast Cancer. Last year, Mr. Madrid walked at a pace of 12 miles
Ilia_Sergeevich [38]
A.

The rate is 12:2

B.

Set up a proportion:

12/2 = x/5

Multiply 5 to both sides:

60/2 = x

Divide:

30 = x

So he will walk 30 miles in 5 hours.

C.

To find out, we can divide 12 / 2.

12 / 2 = 6 miles per hour

The formula for the area of a triangle is A = bh, where b is the length of the base and h is the height. The equation solved for
mylen [45]
The answer is:  " h = A / b " .
_________________________________________________________
Explanation:
_________________________________________________________
Given:  " A = bh " ;  Solve for "h" ; 
_________________________________________________________

A = bh ; 

↔  bh = A ; 

Divide each side of the equation by "b" ; to isolate "h" on one side of the equation; & to solve for "h" ; 

→  (bh) / b  =  A / b  ; 

to get: 

→  h = A / b .
_________________________________________________________
  The answer is:  " h = A / b " .

Write a compound interest function to model the following situation. Then, find the balance after the given number of years.
Valentin [98]

Answer:

  $23,330.66

Step-by-step explanation:

The compound interest function is ...

  FV = P(1 +r/n)^(nt)

where P is the principal amount ($19,600), n is the number of compoundings per year (4), r is the interest rate (.035), and t is the number of years (5).

Putting these numbers into the formula and doing the arithmetic, we get ...

  FV = $19,600(1 +.035/4)^(4·5) = $23,330.66

PLEASE HELP WITH 37 IM MARKING BRAINLIEST TO THE CORRECT ANSWER
Maru [420]

Answer:

Infinitely many solutions

Step-by-step explanation:

-5.9x - 3.7y = -2.1

5.9x + 3.7y = 2.1

If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.

This leaves us with:

0 = 0

Since this is true, that means there are infinite solutions.
