Step-by-step explanation:
the money that Shelly will owe after buying x sandwiches and using the card will be:
if x < 4 then 15 - 4.5x <= 15 - 3*4.5 = 1.5 she will not owe anything plus she will receive change of $1.5.
if x=> 4 then 4.5x - 15 => 18 - 15 = 3 that is Shelly will owe 4.5x - 15 dollars.
So this is a Pythagorean problem where
A^2+b^2=c^2
a is 2
X is b
5 is c
Plug that into the equation and get
4+b^2=25
B^2=21
B=sqrt(21)=4.6kilometer
There are 1000 millimeters in a meter and 0.001 meters in a millimeter

Answer:
(d) 16
Step-by-step explanation:
Angles opposite sides of the same measure are congruent. Here, the triangle is isosceles, so the base angles are congruent:
2x = 32
x = 16 . . . . . . divide by 2°
Answer:
y = - 5x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
here m = - 5 and b = - 3, hence
y = - 5x - 3 ← equation of line
