Answer:
i only know this
The equation of the line of slope 4 is y=4x+b. The line goes through (-1,-6) If you step 1 unit positive in the x direction you reach the y-axis, (x=0). In order to remain on the line you need to go up 4 units, that is from -6 to -2. y=4x-2.
Step-by-step explanation:
Answer:
Area = 8.1902ft² (Rounded up to 4 decimal places)
Step-by-step explanation:
Let side a = 7.2ft, side b = 3.4ft and angle β = 42°
Area of the triangle will be given by:
1/2 × a × b × sinβ
Area = 1/2 × 7.2 × 3.4 × sin 42°
Area = 8.1902 ft² (Rounded up to 4 decimal places)
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.

First phrase is an equation bc there’s an equal sign. second phrase is an expression bc there’s no equal sign/inequality symbol. the third phrase is an inequality because of this “>” symbol. any symbol like “>” or “<“ represent inequalities. the inequalities also include these < symbols with the lines underneath them!
