Answer:The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) .The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
Step-by-step explanation: 6x² + 11x - 35 = 0.
2x² - 4x - 2 = 0.
-4x² - 7x +12 = 0.
20x² -15x - 10 = 0.
x² -x - 3 = 0.
5x² - 2x - 9 = 0.
3x² + 4x + 2 = 0.
-x² +6x + 18 = 0.
Hello :
let : A(3,0)
the ridus is : CA = <span>√((3-3)² +(0+13)²) = 13
</span><span>he equation of the circleis : (x-3)² + (y+13)² = 169</span>
The point-slope form:
We have
Substitute:
<h3>Answer:</h3><h3>point-slope form: y - 7 = 2(x - 1)</h3><h3>slope-intercept form: y = 2x + 5</h3><h3>standard form: 2x - y = -5</h3>
It's asking you to shift the graph of; y = 5x up 3 units. if you add 3 to the equation, all y-values will be increased by 3 this shifts the graph up exactly 3 units.
y = 5x + 3
