Answer:

Step-by-step explanation:

candy sold vs money earned

money earned =  2 dollars * number of bars sold- cost of bars

money earned = 2 b -20

this is an equation of a line

(y= 2x-20)  

A.The relationship is linear    true

B.The relationship is nonlinear   false

C.The relationship is always results in a negative profit   false

it crosses the x axis at 10 candy bars

D.The relationship always result in a positive profit   false

it crosses the x axis at 10 candy bars

E.The relationship is proportional   false

F.The relationship is non-proportional  true  it is a line that does not cross the origin

Explain why the equation 5(2x+1)-2=6x+5 has only one solution. Then find the solution.
netineya [11]

Answer:

10x + 3 = 6x + 5

Based on this, we have the lines y=10x+3 and y=6x+5. Both of the equations are linear, so they are straight lines when graphed. A system of straight lines can only have one solution maximum.

Solution:

x = 1/2

y = 8

(1/2 , 8)

Step-by-step explanation:

Start by expanding with the distributive property, then simplify by collecting like terms.

5(2x + 1) - 2 = 6x + 5     Multiply "5" with each term in the brackets.

10x + 5 - 2 = 6x + 5       Collect left side's like terms (5 - 2 = 3)

10x + 3 = 6x + 5

Based on this, we have the lines <u>y=10x+3 and y=6x+5</u>. A solution is the same as the POI (point of intersection). Both of the equations are linear, so they are straight lines when graphed. A system of straight lines can only have one solution maximum.

Some linear systems might have no solutions (when the lines are parallel) or infinite solutions (when the lines are equivalent, the same).

To find the solution, continue with the equation and isolate "x". This will give you the x-coordinate of the point of intersection.

To isolate 'x', move everything to the other side of 'x'. To move something, you do its reverse operation to both sides in reverse BEDMAS order.

10x + 3 = 6x + 5

10x - 6x + 3 = 6x - 6x + 5     Subtract 6x from both sides

4x + 3 = 5     "6x" cancelled out on the right. Simplified left (10x-6x=4x)

4x + 3 - 3 = 5 - 3      Subtract 3 on both sides. "3" on the left will cancel out

4x = 2      The right side was simplified (5 - 3 = 2).

4x/4 = 2/4      Divide both sides by 4 to isolate 'x'. Simplify right side.

x = 1/2          Solution's x-coordinate

Substitute what you found for 'x' into any equation that has 'y' (either <u>y=10x+3 or y=6x+5</u>). I will choose the first equation.

y = 10x + 3      

y = 10(1/2) + 3        Multiply 1/2 and 10

y = 5 + 3       Add

y = 8          Solution's y-coordinate

Therefore the solution is when x=1/2 and y=8, or as an ordered pair, (1/2 , 8).

A quantity b varies jointly with c and d and inversely with e. When b is 18, c is 4, d is 9, and e is 6. What is the constant of
Fantom [35]
B\alpha\frac{cd}{e}
b=k \frac{cd}{e}
Where k is a constant of proportionality.
b=18, c=4,d=9, e=6
Finding the value f k,
18=\frac{k*4*9}{6}
6k=18
k=3
The equation then is;
b=\frac{3cd}{e}
The constant of variation=3
