Hello. There was no figure to look at so I plotted all of these points for you. Which one looks like the figure to you? That will be your answer.
Remember, you plot the first number first, which will be along the X axis on a graph. Thats the line that runs right to left.
Then you plot the second number, which will be along the Y axis on a graph.
Thats the line that runs up and down.
If you go down or to the left, you will have a negative point. If you go up or to the right you will have a positive point.
Answer:
Step-by-step explanation:
2x² + 9x = -7
2x² + 9x + 7 = 0
When we multiply we should get 2*7 = 14 and when we add we should get 9. Find the factors of 14 ---> 1,2,7,14. Factors are 2,7 as when we multiply we get 14 and we we add, get 9
2x² + 2x + 7x + 7 = 0
2x( x + 1) + 7 (x + 1) = 0
(x + 1)(2x + 7) = 0
Answer:
The answer is "
"
Step-by-step explanation:
In this question, when two figures are similar so, the ratio from its size is equal to the squared factor that are:
Scaling factor= Z
Area of Polygon Y=a
Area of Polygon X=b
![z=\frac{1}{3}\\\\using \ substitution:\\\\(\frac{1}{3})^2=\frac{a}{b}\\\\\frac{1}{9}=\frac{a}{b}\\\\a=\frac{1}{9}b](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B1%7D%7B3%7D%5C%5C%5C%5Cusing%20%5C%20substitution%3A%5C%5C%5C%5C%28%5Cfrac%7B1%7D%7B3%7D%29%5E2%3D%5Cfrac%7Ba%7D%7Bb%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7B9%7D%3D%5Cfrac%7Ba%7D%7Bb%7D%5C%5C%5C%5Ca%3D%5Cfrac%7B1%7D%7B9%7Db)
