Answer: The slope of the line = 4.

Step-by-step explanation:

We know that ,

Slope of a line passes through $(x_1,y_1)$ and $(x_2,y_2)$ = $\dfrac{y_2-y_1}{x_2-x_1}$

Here , the line passes through points (2,18) and (8,42).

Then the slope of the given line = $\dfrac{42-18}{8-2}$

$=\dfrac{24}{6}=4$

Hence, the slope of the line = 4.

Solve for x*<br> (17x - 8)

djyliett [7]

Answer:x=4

Step-by-step explanation:

This triangle is an equilateral triangle with all angles equal.

Sum of angles in a triangle=180

17x-8+17x-8+17x-8=180

Collect like terms

17x+17x+17x-8-8-8=180

51x-24=180

51x=180+24

51x=204

Divide both sides by 51

51x/51=204/51

x=4

1. The value of k for which equation 9x2 + 8xk+8 = 0 has equal roots is:

Nesterboy [21]

Answer:

Option C

+ or - 3

Step-by-step explanation:

A quadratic equation will have equal roots if its Discriminant is equal to zero.

the discriminant in this case is $b^{2}- 4 ac$

considering the equation,

$9x^{2} + 8xk+8 = 0$

a = 9, b= 8k, c=8

Replacing the variables in the original equation with their respective values, we will have:

$8k^{2}- 4 \times 9 \times 8=0\\64k^{2}=288\\k=\sqrt{288/64} =\sqrt{9/2}$

Note: The values of k are meant to be + or -2.12 as seen from the workings

However, these are not in the options given. the closest choice to it

is + or - 3
