Determine if the ordered pair (6, 4) is a solution to the inequality

Mathematics

kvasek [131]3 years ago

Answer:

A

Step-by-step explanation:

all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :

pay attention that here we have x=6  y=4

4<\frac{3}{4} (6) - 3

we simplify we get :

4<4.5-3  

4<1.5  which is incorrect  so (6,4) is not a solution. moreover

notice that 4 is > than 1.5  so the point lies above the line

thus the answer is : A

you can also solve this problem by graphing the line y=\frac{3}{4} x-3  and plotting the point (6,4)  and hence you will notice that the point is above the line

Answer:

<h2>A. No, because (6, 4) is above the line</h2>

Step-by-step explanation:

y

\text{Other mathod:}\\\\\text{Show this inequality in the coordinate system.}\\\\\text{Draw the dotted line}\ y=\dfrac{3}{4}x-3.\\\\for\ x=0\to y=\dfrac{3}{4}(0)-3=0-3=-3\to(0,\ -3)\\\\for\ x=4\to y=\dfrac{3}{4}(4)-3=3-3=0\to(4,\ 0)\\\\\text{shaded region below the line}\\\\\text{Mark point (6, 4) and check if it lies in the shaded region.}

2. Solve the equation p2 + 6p = 1 by completing the square method. Show your work.
goldfiish [28.3K]

Answer:

p=0.125

Step-by-step explanation:

2p+6p=1

Add like terms

8p=1

Divide both sides by 8 to get p by itself

8p/8=1/8

p=0.125

What is the equation standard form of through (2,-4))and the slope is -4
Sloan [31]

Answer:

4x + y = 4

Step-by-step explanation:

Equation of Line in point slope form is given as:

y - y_1= m(x-x_1)

Plug x_1= 2\: and\: y_1= - 4 in the above equation we find:

y - ( - 4) =  - 4(x - 2) \\  \\ y + 4 =  - 4x + 8 \\  \\ 4x + y + 4 - 8 = 0 \\  \\ 4x + y - 4 = 0 \\ \\ 4x + y = 4 \\this \: is \: the \: required \: equation.
