Johnny ask for 8 fewer items then bobby, bobbys list had 3 more then johnny there’s actually 2answers 13 and 5
Answer:
x = 1 and y = 1
Step-by-step explanation:
You can eliminate x first to get the value of y which is 1 and then replace it in one of the equations.
Answer:
How about; Six cats live in a house. Twenty more cats move in. It cost $3 to feed each cat. How much $ do you need to feed all the cats?
This is just and idea lol please don't use it as your own. it would be plaigarism and if someone found out the teacher would give you 0% or F. Hope this helps though!
Step-by-step explanation:
Answer:
(6)
Step-by-step explanation:
Since it is an isosceles trapezoid the length of the two legs (i.e. AB = 5y-10 and CD = 2y+8) are equal. In other words,
5y - 10 = 2 y + 8
Subtract 2y from each side:
5y - 2y - 10 = 8
Now add 10 to each side
5y - 2y - 10 + 10 = 8 + 10 =>
3y + 0 = 18 =>
3y = 18 =>
y = 6
Answer:
B. x < -4 and x > 3
Step-by-step explanation:
Factor and set = to 0
= 0
x = - 4 or x = 3 I call these critical values
The two numbers would divide a number line into 3 intervals. Pick a value in one of the intervals and put it in the original expression. If it makes the function positive, then all the values in that interval make the function positive. If the value you picked makes the function negative, then the values in the other intervals will make the function negative. Let's pick the value of 0 and substitute it into the function
We get
+ 0 - 12 = -12 which is not positive. Therefore, all the values between -4 and 3 will make the function negative. So, the values less than -4 or greater than 3 will make the function positive. Therefore, B is the correct answer.
Another way to do this problem is to graph the function and see where the graph is above the x-axis. But, sometimes it is not easy to graph the function.
