Which point on the graph shows the price of 6 ounces of cheese? Use the formula y=x÷2 to find y when x is 6.
RSB [31]

The value of y is 3 when x is 6.

Solution:

The given table is the amount of cheese in ounces and the cost price.

Let x represents the amount of cheese and y represents the cost price.

The formula which derived from the table is y = x ÷ 2.

That is $y=\frac{x}{2}.

<u>To find the value of y when x is 6:</u>

$y=\frac{x}{2}

Substitute x = 6 in the formula, we get

$y=\frac{6}{2}

y = 3

Hence the value of y is 3 when x is 6.

If LN=3+8x, find LN<br><br> L•——–8•——M——6x-1——–•N
ElenaW [278]

Answer:

Value of LN = 19 units

Step-by-step explanation:

Given:

LN = 3 + 8x

Find:

Value of LN

Computation:

We know that LM + MN = LN

So,

8 + 6x - 1 = LN

So,

3 + 8x = 8 + 6x - 1

3 + 8x = 7 + 6x

8x - 6x = 7 - 3

2x = 4

x = 2

So,

LN = 3 + 8x

LN = 3 + 8(2)

LN = 3 + 16

LN = 19

Value of LN = 19 units

80 points!!! I desperately need help! tell me how to do this! PLZ<br>(4k+5)(k+1)=0
Len [333]

Lets solve your equation step by step:

(4k + 5)(k + 1) = 0



Step 1: Simplify both sides of the equation:

4k^2 + 9k + 5 = 0



Step 2: Factor left side of equation:

(4k + 5)(k + 1) = 0



Step 3: Set factors equal to 0:


4k + 5 = 0 or k + 1 = 0


k = - 5/4 or k = - 1






Answer: k = - 5/4 or k = - 1








Hope that helps!!!! ( Answer: k = -5/4 or k = -1)

solve the system of linear equations by graphing. round the solution to the nearest tenth as needed. y 2.3 = 0.45x –2y = 4.2x –
Shalnov [3]
Unfortunately, I can't do it on a graph here, but I will do it algebraically.
The solution on the graph will be the point of intersection of the two lines representing the equations.
y + 2.3 = 0.45x . . . . . (1)
-2y = 4.2x - 7.8 . . . . . (2)
From (2), y = 3.9 - 2.1x
substituting for y in (1), we have:
3.9 - 2.1x + 2.3 = 0.45x
2.55x = 6.2
x = 6.2/2.55 = 2.4
y = 3.9 - 2.1(2.4) = 3.9 - 5.04 = -1.2
Therefore, solution is (2.4, -1.2)

Sketch a graph of the linear relation 8x+2y = 24. Explain the procedure.
Dmitriy789 [7]
First we need the slope and the y int which can be found by putting ur equation in y = mx + b form, where m is ur slope and b is ur y int.

8x + 2y = 24
2y = -8x + 24
y = -4x + 12.....so the slope is -4, and the y int is 12 or (0,12)

to find the x int, sub in 0 for y and solve for x....in either the original equation or the slope intercept equation
8x + 2y = 24
8x + 2(0) = 24
8x = 24
x = 24/8
x = 3.....so the x int is 3 or (3,0)

now plot ur intercepts (3,0) and (0,12)......now start at ur y int (0,12)...and since ur slope is -4, u come down 4 spaces, then to the right 1 space, then down 4, and to the right 1...keep doing this and u should cross the x axis at (3,0)
