Which numbers are a distance of 7 units from 1 on a number line? Select the location on the number line to plot each point.
1 answer:
We need to find the numbers those are 4 units far from 1.
If we go to 7 units left side of 1 on number line we would add -7 to 1, we get
1-7 = -6.
And if we go to 7 units right side of 1, we would add +7 on 1 to get the number.
1+7 =8.
<h3>First we would plot a number 1 on number line.</h3><h3>Then we would go 7 units on the left side of 1 on number line, we would get -6.</h3><h3>Now, we would go 7 units right of the right side of 1 on the number line, we would get 8.</h3>

Answer:
The quadratic equation form is x² - 9 x + 14 = 0
Step-by-step explanation:
Given in the question as ,
The solution of quadratic equation are x = 2 and x = 7
The constant K is a non-zero number
Now , let the quadratic equation be , ax² + bx + c = 0
And sum of roots =
product of roots =
So, 2 + 7 =
Or, 2 × 7 =
I.e = 9 ,
= 14
Or, b = - 9 a And c = 14 a
Put this value of b and c in standard form of quadratic equation
I.e ax² + bx + c = 0
Or, ax² - 9 ax + 14 a = 0
Or , a ( x² - 9 x + 14 ) = 0
∴ a = 0 And x² - 9 x + 14 = 0
Hence , The quadratic equation form is x² - 9 x + 14 = 0 Answer
