A function cannot have multiple outputs (y-values) for any given input
(x-values). For example, y=2x+3 is a function because no mater what
number x represents, there is a single, unique y-value (When x=3 y=9 ).
In other words, you can never have two (or more) y-values that
correspond to a single x-value. Therefore, a vertical line, for example
x=2, cannot be a function because it has an infinite amount of y-values
for a single x-value. A horizontal line is a function
because there is only one y-value for any given x-value. For example,
y=3. No mater what x-value is used, there is only one y-value possible
(in this case, y will always equal 3). I am, of course,
referring to the cartesian coordinate system, also known as the
rectangular coordinate system
Step-by-step explanation:
AO = DO
2x+3 = 5x
3 = 5x-2x
3 = 3x
x = 1
DO = 5(1)=5cm
AC = 2×5 = 10cm
BC =√10²-8²
= √100-64
=√36
=6 cm
therefore, the perimeter of the rectangle
= 2×(8+6) = 2(14) = 28 cm
Answer:
Step-by-step explanation:
Let the no. Of rye bread = x
Wheat bread = x + 8
The total bread is 32
: x + x + 8 = 32
2x = 32 - 8
2x = 24
x = 24/2
x = 12
No. Of wheat bread = x + 8 = 12+8
No. Of wheat bread = 20
Answer:
Step-by-step explanation:
Subtract 1/10 from 9/10 to find out how much is left.
9/10 - 1/10
8/10 = 4/5
Answer:177
Step-by-step explanation:so for short, you need to multiply the 300 miles with the 59 precent we have and divide it to 100 this provides us the answer of miles he slept through the road trip
