How many solutions does the system have? y=−2x+4
Anna11 [10]

Answer:

There is only one solution and the solution is (0,4).

Step-by-step explanation:

The given system has equations;

y=-2x+4

and

y=x^2-2x+4

We equate the two equations to determine their point of intersection;

x^2-2x+4=-2x+4

\Rightarrow x^2-2x+2x+4-4=0

\Rightarrow x^2=0

\Rightarrow x=0

We put x=0 into the first equation to get;

y=-2(0)+4=4

There is only one solution and the solution is (0,4).

Serggg [28]

Answer:

32%

Step-by-step explanation:

<h3>Given that:</h3>
  • Jackie is saving money to buy a new cell phone.
  • The cell phone costs $175
  • she has already saved $56
<h3>To find:</h3>
  • The percent of the cost of the cell phone has Jackie saved

In order to find the percent of the cost of the cell phone has Jackie saved,

  1. divide the cost of the cell phone by the amount of the money Jackie saved
  2. Multiply the result (1) by 100

See below how it's done:

\dfrac{56}{175}  \times 100

dividing yields:

0.32 \times 100

multiplying yields:

32\%

Alternative:

Instead of dividing,we can consider reducing the fraction and multiply that with 100 to get the answer.

\dfrac{56}{175}  \times 100 \\  \implies  \frac{8}{25}  \times 100 \\ \implies 8 \times 4 \\  \implies \boxed{32\%}

In conclusion:

Jackie has saved 32% of the cost of the cell phone

Vladimir [108]
She is incorrect 

the GCF of 2, 4 and 8 is 2  (not 8 has she has written)

the GCF of x2, xy and xy4  is x   not x2y4

Correct GCF of the 3 terms is 2x
