What is the equation if x=1 and y=16/3

1 answer:

4 0

There may be more than one way in which to answer this question. I will assume that the "equation" is a linear one: f(x) = mx + b.

Then (16/3) = m(1) + b
This is one equation in two unknowns, so it does not have a unique solution. Was there more to this problem than you have shared?

If we assume that the y-intercept (b) is zero, then y = mx, and

16/3 = 1m, so that m = 16/3, and so y = (16/3)x.

How many real solutions does the equation 8x^2 − 10x + 15 = 0 have?

Nimfa-mama [501]

Answer:

The correct option is (A) No real solution.

Step-by-step explanation:

The expression provided is a quadratic equation.

$8x^{2}-10x+15=0$

The roots of a quadratic equation are:

$x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{ 2a }$

Here,

a = 8

b = -10

c = 15

The conditions to determine real and complex roots are:

If $b^{2}-4ac$ then the quadratic equation has two complex roots.
If $b^{2}-4ac>0$ then the quadratic equation has two real roots.

Compute the value of $b^{2}-4ac$ as follows:

$b^{2}-4ac=(-10)^{2}-(4\times 8\times15)\\\\$

$=100-480\\=-380\\$

The equation has two complex roots.

Thus, the correct option is (A).

The hypotenuse of a 30-60-90 triangle is 12 inches long. How long is the leg opposite the 60 degree angle?

atroni [7]

Answer: D

Step-by-step explanation:

Remember that the Opposite side to an angle is in the same order of length as the Angle. So, $90 = 12, and 60 = 8$ . Using Cross multiplication, this answer can be solved:

$\frac{90}{12} = \frac{60}{n}$ , 60 x 12 = 720, and 90 x 8 = 720. N = 8.

$\frac{90}{12} = \frac{30}{n}$ , 30 x 12 = 360, and 90 x 4 = 360. N = 4
