In a quadratic equation, the formula is:  ax^2 + bx + c = 0

In the given formula 2x^2 + 4x -6 = 0:

a = 2, b = 4 and c = -6

Using the quadratic formula x1, x2 = -b+/-sqrt(b^2-4ac)/2a

Replace am b and c with their values and solve:

Now you have the 2 x values :

x1 = 1, x2 = -3

1^2 + -3^2 = 1 + 9 = 10

What is the answer to this?
Keith_Richards [23]

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.  

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

z^{2}  = 28.31^{2}  - 25^{2}

z = 13.29

Find the x- and y-intercepts of the graph of the linear equation −x+8y=4.
Ulleksa [173]
X intercept: (-4,0)
y intercept: (0,1/2)

x-intercept is when y = 0
-x+8(0)=4
-x+0=4
x=-4

y-intercept is when x = 0
-(0)+8y=4
8y=4
y=4/8=1/2
