Solve the quadratic equation and give both solutions.<br><br> 14x^2 − 29x − 15 = 0
BartSMP [9]

Answer:

Step-by-step explanation:

x_{1,\:2}=\frac{-\left(-29\right)\pm \sqrt{\left(-29\right)^2-4\cdot \:14\left(-15\right)}}{2\cdot \:14}     so    x=\frac{5}{2}     x=-\frac{3}{7}

NEED ANSWER FAST!<br> what is the value of X?
vredina [299]
<span>Angles on one side of a straight line always add to 180°.

Look at the picture.

a = 180° - 134° = 46°
b = 180° - 130° = 50°

</span><span>In a triangle, the three interior angles always add to 180°.

a + b + c = 180°

c = 180° - (46° + 50°) = 180° - 96° = 84°

x° = 180° - 84° = 96°

</span>
<span>We can see that:
x = a + b

You don’t have to answer all just help. please
Studentka2010 [4]

Answer:

Step-by-step explanation:

a.) When you have the following equation a(x-h)^2+z To find the vertex you take the h value, change its sign (to positive in this case) and that will give you the x value. To find the y-value just take the z. This gives us (15,-100)

b.) The axis of symmetry is just the x value of the vertex which is 15

c.) I'm not too sure what this means but can tell you that it's concave up because there's no way x can be negative

d.)Because the a value is positive that means that the graph is concave up which means that it has a minimum. The minimum is just the y value of the vertex which is just -100

e.) I'm going to write this in interval notation. The domain is all the possible x values of the graph which is all real numbers or (-∞,∞). The range is all the possible y values. We know that the minimum is -100 which means all the possible y values are [-100,∞)

f.) This is obviously a parabola and because the graph is concave up and has a negative minimum there must be 2 x intercepts.
