The line AB is shown on the grid.
1 answer:
a) The gradient of a line perpendicular to AB is -2.
b) equation of line is y=-2x+6
<h3>What is gradient?</h3>The gradient is the measure of the steepness of a straight line.
a)The gradient of line is
=(-2-2)/(7+1)
=-4/8
=-1/2
So, gradient of a line perpendicular to AB is -2
b)The coordinates of mid point (3, 0)
m = -2
So,
0= -6+ b
b= 6
So, equation of line is y=-2x+6

Answer:
Here, b represents buying fins and leashes.
As per the statement:
Vincent is ordering accessories for his surfboard. A set of fins cost $24 each and a leash costs $15.
A set of fins cost $24 each and a leash costs $15
⇒ Cost of total fins = 24 b and Cost of total leashes = 15 b
It is also given that: The shipping cost is $4 per order.
then;
Cost in dollars of buying b fins and b leashes plus the cost of shipping
=
Therefore, the expression represents the cost in dollars of buying b fins and b leashes plus the cost of shipping.

(a)
True.
The given terms in the expressions are 24b, 10b and 4
(b)
True.
Like terms are those which have same variable.
Like terms in the given expression are: 24 b and 15 b
(c)
False.
Combine like terms in the given expression:
Therefore, the simplified given expression is,
Answer:
Step-by-step explanation:
meants when
, that the value for
is 5.
So this gives us this equation:
meants when
, that the value for
is 10.
So this gives us this equation:
So I take equation 2 and divide it be equation 1 I get:
Simplifying:
Since the base for an exponential function can't be negative then .
So plugging into one of my equations I began with gives me an equation to solve for the initial value,:
Divide both sides by 2:
The function is:
