Answer:
See below.
Step-by-step explanation:
1)
So we have:
This can be interpreted as:
"There exists a natural number <em>x</em> and an integer <em>y</em> such that x² is equal to y²."
2)
So we want even numbers are in the set of integers.
This is interpreted as:
"The set of even numbers (2n such that n is an integer) is in the set of integers"
Y intercept is where the graph crosses the y axis or wheren x=0
set x=0 and solve
y=0+5
y=5
yintercept=5 aka the point (0,5)
one way to graph is to find the x and y intercepts and connect
y intercept is when x=0
x intercept is when y=0
yint, y=0+5, y=5 graph point (0,5) (from origin, go 5 units up)
xint, 0=x+5, subtract 5, -5=x, point (-5,0) (from origin go 5 units left )
then connect the points
Answer:
the desired equation is y = 3^x
Step-by-step explanation:
if x = 2, then y = 9, and 9 is 3². If x = 4, y = 81 = 3^4.
Therefore we can conclude that the desired equation is y = 3^x
Given:
The temperature on the moon can vary from -172 to -126 degrees Celsius.
To find:
The difference between the maximum and minimum temperatures.
Solution:
It is given that the temperature on the moon can vary from -172 to -126 degrees Celsius.
Since , therefore the minimum temperature is -172 and the maximum temperature is -126.
The difference between the maximum and minimum temperatures is:
Difference = Maximum temperature - Minimum temperature
Therefore, the difference between the maximum and minimum temperatures is 46 degrees Celsius.
Answer:
3.8
Step-by-step explanation:
0.2 x 7=1.4
1.4+2.4=3.8
