A proportional relationship between the number of pounds of cabbage (x) and the price in dollars (y) is graphed, and the ordered

Marta_Voda [28]

Answer: A. 1 pound of cabbage will cost 40 cents. B. (10,4) means that 10 pounds of cabbage will cost 4 dollars.

Step-by-step explanation:

If it is proportional that means the y value divided by the x value will give you a constant slope.

So using that use the coordinates (5,2) to find the cost of 1 pound of cabbage.

2/5 = 0.4

so you could write the equation y= 0.4x where x is the number of pound.

Part A: y= 0.4(1)

y= $0.40 which means one pound of cabbage will cost 40 cents.

Part B. (10,4) in this case it will means that for 10 pounds of cabbage it will cost $4.

Plot it into the equation and find out

in the coordinates (10,4) 4 is the y and 10 is the x

4= 0.4(10)

4= 4

Which means it true that 10 pounds of cabbage will cost 4 dollars.

Solve the following equations;- x - 9 /√x + 3 =1

fgiga [73]

Answer:

13 , 6.

Step-by-step explanation:

A equation is given to us and we need to find out the value of x . The given equation to us is ,

$\sf\implies \dfrac{ x -9}{\sqrt{x+3}}= 1$

Cross multiply ,

$\sf\implies x - 9 =\sqrt{ x +3}$

Squaring both sides ,

$\sf\implies (x - 9)^2 = x + 3$

Simplify the whole square ,

$\sf\implies x^2+9^2-2.9.x = x +3 \\$

$\sf\implies x^2+81 - 18x = x -3$

Add 3 and subtract x on both sides ,

$\sf\implies x^2 -18x-x +81-3=0$

Simplify ,

$\sf\implies x^2 -19x +78=0$

Split the middle term of the quadratic equation,

$\sf\implies x^2-13x-6x+78=0$

Take out common ,

$\sf\implies x( x -13)-6(x-13)=0$

Take out ( x -13 ) as common ,

$\sf\implies ( x -13)(x-6)=0$

Equate both factors to 0 ,

$\sf\implies \boxed{\pink{\sf x = 13,6}}$

Hence the value of x is 13 or 6 .
