This one is pretty easy.
x+ 4 = 7
Subtract 4 from both sides so you can isolate the x (Get the x alone)
x = 7 -4
x = 3
That's your answer. 3.
Answer: There are 5 red pencils, 16 blue pencils and 23 brown pencils.
Step-by-step explanation:
Since we have given that
Number of red pencils = 5
Number of blue pencils are 11 more than red pencils.
So, Number of blue pencils would be
Number of brown pencils are 7 more than blue pencils.
So, number of brown pencils would be
Hence, there are 5 red pencils, 16 blue pencils and 23 brown pencils.
Answer:
Yes, it is a function
Step-by-step explanation:
Every possible input x value is paired with a unique output y value.
Another approach is to graph the function then conduct the VLT (vertical line test) at which point you will realize that any vertical line will intersect the graph at one point only meaning it is a function.
Hope this helps.
Answer:
a=(2/5), b = (-2,6)
Step-by-step explanation:
well slope formula is rise/run. So for the first one you start at the point rise 2 run 5 and you reach the endpoint. That is how you know you got the correct slope. (2/5)
For the second one you start at the first point and you cannot go up because it is a negative slope you run 6 till you hit the other point go down 2. Since you go down 2 that would make it -2. (-2,6)
