Answer:
0
Step-by-step explanation:
(x₁ , y₁) = (-9, -2)
(x₂ , y₂) = ( 5 , -2)
In these two points, there is no change in the y co-ordinates. So the line is parallel to x-axis.
slope of line parallel to x-axis = 0
First, you have to convert 33% to decimals by dividing it to 100. And that would be 0.33.
Then you want to know the 100 percent of 198 because it's just a 33% part of a whole.
You will have to divide 198 by 33% or 0.33 to get the whole. So the answer would be 600.
If you're going 804 miles in 16 hours, you're going to want to do 804 / 16, which is 50.25, so you're going either 50.25 mph or 50 1/4 mph depending on the format you choose.
Answer:
1°F to 7°F is the best range to store ice cream.
Step-by-step explanation:
The ideal storage temperature of ice cream = 4°F
The allowance in the temperature is 3°F
So, the range of the store = 4°F ± 3°F
Now, 4°F + 3°F = 7°F
and 4°F - 3°F = 1°F
Hence, 1°F to 7°F is the best range to store ice cream.
Answer:
Hey there!
When we are given what one of our variables is equal to, we can easily solve the system of equations via substitution, which is where we take the variable value, plug it into the other equation, and solve for the other variable.
In this case, we just take our value for y and plug it in for the value for y in the first equation and solve for x.
2(-x+7)=14-2x
-2x+14=14-2x
-2x=-2x
x=x
As we can see, there are infinitely many solutions to this first equation, which means that there is no possible way to solve for y because x has infinitely many solutions, so there are infinitely many solutions to this system of equations, because they are both the same line.
I hope this helps! :D
