Answer: 5.4n to the power of 5.
Step-by-step explanation: Remove parentheses. 4n 5 +3.5n 5
−2.1×n 5
You get 5.4n to the power of 5
Take a arbitrary line out of the figure and compare it to the same line in the other figure. You can see that every line from the left figure is halved in the second figure. The scale factor is therefore 1/2
Answer:
Step-by-step explanation:
Vertex form of a quadratic equation;
Vertex of the parabolas (h, k)
The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;
Now substitute in the given point; ( -1, 9) and solve for a;
Hence the equation in vertex form is;
In standard form it is;
Answer:
Step-by-step explanation:
y = –⁷⁄₉x + 5
+ ⁷⁄₉x + ⁷⁄₉x
___________
⁷⁄₉x + y = 5 [We CANNOT leave the equation like this, so multiply by 9 to eradicate the fraction.]
9[⁷⁄₉x + y = 5]
