Distributive property is
a(b+c)=ab+ac
we can make it easier by splitting up 63 into 60+3
so
7(63)=7(60+3)=7*60+7*3=420+21=441
Explanation:
All values in the x-column get filled with -2.
The graph is the vertical line, x = -2.
__
You are told x=-2. There is nothing to figure out. The value of y is irrelevant.
That equation describes a vertical line. The points on the line have x-coordinate -2, and any (every) y-coordinate.
Answer:
The value of the 2nd expression is 14, so the expressions are equivalent.
Step-by-step explanation:
6 + 2x - 2
6 + 2(5) - 2
6 + (10) - 2
16 - 2
14
Answer:
Step-by-step explanation:
The function
has a horizontal asymptote which is 
The function
has a horizontal asymptote which is 
The function
has no horizontal asymptote because the numerator has a degree which is higher than the degree of the denominator,
The function
has a horizontal asymptote which is 
Answer:
y = 2x - 1
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = A(4, 7) and (x₂, y₂ ) = B(2,3)
m =
=
= 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 3), then
3 = 4 + c ⇒ c = 3 - 4 = - 1
y = 2x - 1 ← equation of line
