Can you take a picture of the tables so i can see my choices??
Answer:
14:6
21:9
28:12
Step-by-step explanation:
Given the initial ratio of 7:3, you can find equivalent ratios by multiplying the two numbers by the same factor:
7 x 2 = 14
3 x 2 = 6
14:6
7 x 3 = 21
3 x 3 = 9
21:9
7 x 4 = 28
3 x 4 = 12
28:12
Answer:
Step-by-step explanation:
Given equation of the quadratic function is,
y = x² + 5x - 7
Convert this equation into vertex form,
y = x² + 2(2.5x) - 7
= x² + 2(2.5x) + (2.5)² - (2.5)² - 7
= (x + 2.5)²- 6.25 - 7
= (x + 2.5)² - 13.25
Therefore, vertex of the function is → (-2.5, -13.25)
For the solutions,
y = 0
(x + 2.5)² - 13.25 = 0
x = (±√13.25) - 2.5
x = (±3.64) - 2.5
x = 1.14, -6.14
Solutions → (-6.14, 0) and (1.14, 0)
Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values. Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.
