Is (2, 6) a solution to this system of equations? y = -x + 8 y = 5x - 4 yes no

Alexxx [7]

Answer:

Yes

Step-by-step explanation:

To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:

6 = -2+8

6 = 6

6 = 5(2)-4

6 = 10-4

6 = 6

Both of the equations are true, therefore (2, 6) is a solution to this system.

What is the value of x to the nearest tenth. <img src="https://tex.z-dn.net/?f=%20%5Ctan%2834%20%29%20%3D%20%20%5Cfrac%7B

$tan(34)=\frac{x}{20} \\\frac{tan(34)}{1} * \frac{x}{20}\\x= 20*tan(34)$

*use calculator to get final product

$x = 13.490$

*x is not equal to 13.490 it is an estimation so use (≈)

The equation of the hyperbola in standard form is $\frac{(y-4)^{2}}{100}-\frac{(x-1)^{2}}{64}=1$

Step-by-step explanation:

Let us revise the equation of the hyperbola

The standard form of the equation of a hyperbola with center (h , k) and transverse axis parallel to the y-axis is $\frac{(y-k)^{2}}{a^{2}}-\frac{(x-h)^{2}}{b^{2}}=1$

The length of the transverse axis is 2a
The length of the conjugate axis is 2b

∵ The center of the hyperbola is (1 , 4)

∴ h = 1 and k = 4

∵ The transverse axis is parallel to the y-axis

∴ The form of the equation is $\frac{(y-k)^{2}}{a^{2}}-\frac{(x-h)^{2}}{b^{2}}=1$

∴ The length of the transverse axis is 2a

∵ The length of the transverse axis is 20 units

- Equate 2a by 20 to find a

∴ 2a = 20

- Divide both sides by 2

∴ a = 10

∵ The length of the conjugate axis is 2b

∵ The length of the conjugate axis is 16

- Equate 2b by 16 to find b

∴ 2b = 16

- Divide both sides by 2

∴ b = 8

- Substitute the values of h, k, a, and b in the form of the equation

∴ $\frac{(y-4)^{2}}{(10)^{2}}-\frac{(x-1)^{2}}{(8)^{2}}=1$

∴ $\frac{(y-4)^{2}}{100}-\frac{(x-1)^{2}}{64}=1$

The equation of the hyperbola in standard form is $\frac{(y-4)^{2}}{100}-\frac{(x-1)^{2}}{64}=1$

5d2-50d+125 = Fully factor each expression

Ede4ka [16]

First, let's start off by simplifying as much as possible before factoring.

5d^2 - 50d + 125

We can divide all the numbers by 5 in order to simplify it:

5(d^2 - 10d + 25)

Now all we need to do is factor.
Since -5*-5 = 25 and -5 - 5 = -10, we can use this to factor:

5(d - 5)(d - 5)
Or
5(d - 5)^2
