Answer:
65 < or equal to x > or equal to 100
Ps: had to put "or equal to", because I can't put the lines underneath
Anyways, when an inequality says and, it is automatically a compound inequality. The x is in the middle.
<span>Let x represent Harry's age now, and Nick's age now is 7x. [t]
In 6 years, Harry is x + 6 , and it is given that Nick's age will be 5(x+6). [t+6]
Combining [t] and [t+6], 7x + 6 = 5(x+6).
So the formula 7x + 6 = 5(x+6) represents the problem.
And x = 12 , so Harry's age in 6 years will be x +6 or 18 years .
I hope this helps!</span>
The two roots obtained for the quadratic equation by quadratic formula are 1.5 and 4.
<h3>What is defined as the quadratic formula?</h3>
- A quadratic equation is just a polynomial with a second degree first term.
- There are several methods for determining the roots, or solutions, of such a quadratic equation.
- Every quadratic equation has two solutions, that might or might not be real numbers.
- The quadratic formula is a simple method for resolving a quadratic equation. whether the answer is a whole number, an irrational number, or perhaps an imaginary number
If the quadratic equation is ax² + bx + c = 0.
Then, the roots are given by x = [-b ± √(b² - 4ac)]/2a.
The quadratic equation is given as; 2x² - 5x - 12 = 0.
On comparing with the standard form;
Put the values in the formula,
x = [-b ± √(b² - 4ac)]/2a.
x = [-(-5) ± √((-5)² - 4×2×(-12))] / 2×2
On simplification,
x = [5 ± 11]/4
There will be two roots of equation,
a; x = [5 + 11]/4
x = 16/4 = 4
b ; x = [5 - 11]/4
x = 6/4 = 1.5
Thus, the two roots obtained for the quadratic equation by quadratic formula are 1.5 and 4.

Let the missing value = x
Slope is the change in y over the change in x:
3 = (x-2)/ (8-3)
3 = (x-2) / 5
Multiply both sides by 5:
15 = x-2
Add 2 to both sides:
X = 17
The missing coordinate is 17
