Given the following triangle:
Area = 28.5 square in
Height = 7.5 in
We know the area is 28.5 so to find the base we need to ensure that it equals 28.5 after calculating the area.
So the base would be 7.6 inches
8x+2 it’s correct because it’s correct
Answer:
(x, y) → (x+8, y-3)
Step-by-step explanation:
You are moving the x coordinates 8 steps to the right, which is in the positive direction. This makes the change +8. This is where the x+8 comes from.
For the y coordinates, you are moving 3 down, which is in the negative direction which means it is y-3.
(You can pick one point, D, and track its movements. We can see that point D had to move 8 units to the right and 3 units down to become D'.)
Answer:
7x³ + 13x²+ 8x +9
Step-by-step explanation:
(3x² + 2x + 7x³) + (10x² + 6x + 9)
= 3x² + 2x + 7x³ + 10x² + 6x + 9
= 7x³ + (3x²+ 10x²)+ (2x+ 6x) +9
= 7x³ + 13x²+ 8x +9
First of all, observe that the graphed function is .
Now, if we want to shift the graph 4 units up, it means that we want each point on the graph enlarge its y coordinate by 4: we no longer want to associate
but
And since , we want to map
And in our case, , so the answer is
