Solve the system using elimination. Write the solution as an ordered pair. (1 point) SHOW YOUR WORK FOR FULL CREDIT! (2 points)
Gre4nikov [31]

Answer: (1,-1)

Step-by-step explanation:

- You can multiply the first equation by -1

- Add the equations.

- Solve for x, as following:

\left \{ {{-5x - 4y = -1} \atop {-3x + 4y = -7}} \right.\\------\\-8x=-8\\x=1

- Substitute the value of x into any of the original equations and then you must solve for y:

5(1)+4(y)=1\\4y=-4\\y=-1

Therefore, the solution is: (1,-1)

A phone company offers two monthly plans. Plan A costs $11 plus an additional $0.11 for each minute of calls. Plan B costs $27 p
irina1246 [14]

Solution:

Let x represent a number of calling minutes. According to the problem, we want:

11\text{ + 0.11 x = }27\text{ + 0.07 x}

now, putting the similar terms together, we obtain:

0.11\text{ x - 0.07 x = 27 -11 }

this is equivalent to:

0.04x\text{ = 16}

now, solving for x, we get:

x\text{ = }\frac{16}{0.04}\text{ = 400}

then, the correct answer for the first question is:

400 minutes is the number of minutes the two plans cost the same

now, for the second question, we can replace the above value (400 minutes) into the following equation:

11\text{ + 0.11(400) = }55

so that, the correct answer for the second question is:

$55 is the cost when the two plans cost the same

Which of the following is the complete factorization of 25a 2-100
Westkost [7]

Answer:

25(a-2)(a+2)

Step-by-step explanation:

25a^2 -100  

We can factor out 25

25(a^2 -4)

a^2 -4  is the difference of squares a^2-b^2= (a-b)(a+b)

where a =a and b=2

a^2 -4 = (a-2)(a+2)

25a^2 -100 = 25(a-2)(a+2)
