Answer: D
Step-by-step explanation:
An equation would look like this:
x+1=3
An expression would look like this:
x+1
As you can see, an expression has no equal sign. Conversely, an equation does. That is the primary difference between a(n) (algebraic) expression and equation.
Answer: your answer is one.I took the test so I know I got this right ☺️
Step-by-step explanation:
Answer:
y = 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 2 ← is in slope- intercept form
with m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation
To find c substitute (4, 5) into the partial equation
5 = 12 + c ⇒ c = 5 - 12 = - 7
y = 3x - 7 ← equation of line
Permutation is a mathematical operation that is concerned about the ordered of the elements. The word "helicopter" has 10 elements or letters. Only 2 e's are repeated. Hence, the permutation is equal to 10! / 2!. The numerical value of this is equal to 1814400. The answer is letter B.
