Answer:

h\neq 7.5

k = -4

Step-by-step explanation:

Given system of equations are,

-3x-3y = h

-4x + ky = 10

We have to find the values of h and k such that system of equations has no solution.

The standard form of system of equation in two variables can be given by,

a_1x+b_1y+c_1=0

a_2x+b_2y+c_2=0

And condition for the system of equations has no solution is given by,

\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\neq \dfrac{c_1}{c_2}

So, by comparing the standard form of equations with given equations, the condition such that system has no solution can be written as,

\dfrac{-3}{-4}=\dfrac{-3}{k}\neq \dfrac{h}{10}

=>\dfrac{-3}{-4}=\dfrac{-3}{k}

=> k = -4

and \dfrac{-3}{-4}\neq \dfrac{h}{10}

    =>\ \dfrac{-3\times 10}{-4}\neq h

    =>\ h\neq \dfrac{30}{4}

    =>\ h\neq 7.5

So, the value of h and k for above given system of equations is

h\neq 7.5 and k = -4.

Find the equation of the linear function represented by the table below in slope-intercept form.
OLEGan [10]

Answer:

y = 8x+7

Step-by-step explanation:

firstly reduce the equation to an arithmetic series starting from the 0th term so:
7, 15, 23, 31, 39....

Secondly, identify the common difference: 8
we now know that the answer must contain 8x

Thirdly, form the equation 8x + c = y where y is a constant. Afterwards insert the values of any given x and y so:
8*0 + c = 7
c = 7
Thusly we now know that the series and thus equation is 8x+7 = y
