B) The graph of y = x^2–2x + 5 is

Better yet, let y = 6 and solve for x.

6 = x^2 –2x + 5

Now solve for x.

Lizzie bought 0.8 kg of pears at €1.90 per kilogram and 1.4 kg of apples. The total cost €4.46. What was the price per kilogram

scoundrel [369]

Answer:

The the cost of 1 kg apples = € 2.1

Step-by-step explanation:

The amount of pears bought by Lizzie = 0.8 kg

The amount of apple bought by Lizzie = 1.4 kg

Total amount paid = €4.46

Now, the cost of 1 kg pears = €1.90 per kg

So, the cost of 0.8 kg pears = 0.8 x (1.90) = €1.52

Now, let the cost of 1 kg apples = € m

So, the cost of 1.4 kg apples = 1.4 x ( € m) = 1.4 m

So, the total amount = Cost of Apples + Cost of Pears

⇒ €4.46 = €1.52 + 1.4 m

or, 1.4 m = 4.46 - 1.52 = 2.94

⇒ m = 2.94/1.4 = 2.1

or, m = 2.1

Hence, the the cost of 1 kg apples = € 2.1

1. Solve the system.

Sliva [168]

Answer:

Step-by-step explanation:

We put 2nd equation into 1st equation and get y:

$y=\frac{1}{7}x-4\\y=\frac{1}{7}(7y+1)-4\\y=y+\frac{1}{7}-4\\y=y-\frac{15}{4}\\NOTHING$

We can't seem to come to a solution.

Also let's rearrange the 2nd equation into y = something form:

x = 7y + 1

7y = x - 1

y = 1/7 x -1

As we can see BOTH the lines have the same SLOPE, the number before x, which is 1/7 and we know that lines with same slope are parallel, they never intersect.

Having a solution to a system means their intersection point, since they are parallel lines, they don't intersect, and hence DO NOT HAVE A SOLUTION.

D is the correct choice.

Solve for x: −2x − 4 > 8

OverLord2011 [107]

-2x - 4 > 8...add 4 to both sides
-2x > 8 + 4
-2x > 12...divide both sides by -2 and change inequality sign
x < 12/-2
x < -6
