(12/7, 9/7)

Since y = -x + 3, substitute it into the first equation.

-x + 3 = 5/2x - 3

Now add x and subtract 3 from both sides.

0 = 7/2x - 6

Now add 6 on both sides.

6 = 7/2x

Now divide by 7/2 on both sides.

12/7 = x

Now, just substitute x into the second equation.

y = -12/7 + 3

y = -12/7 + 21/7

y = 9/7

When factoring a trinomial of the form ax2 + bx + c where a, b, and c are all positive, you need to find two numbers, m and n, s

Elena-2011 [213]

Answer:

A. m and n both are positive is correct choice.

Step-by-step explanation:

We have been given that When factoring a trinomial of the form ax2 + bx + c where a, b, and c are all positive. That means:

a>0

b>0

c>0

Then ac>0 as product of same sign numbers is always positive.

Positive produce ac is possible only when both factors are of same sign.

In this situation, b>0 is possible only if both numbers are positive.

Hence choice A. m and n both are positive is correct choice.

XD Plzzzzzz do 2 slides (4 problems)

Leya [2.2K]

Answer:

Slide 1:

1. Solution = (-3,2)

y = 2x - 1

y = 3/2x + 6

2. No solution

y = -4/2x + 4

y = -4/2x - 5

Slide 2:

3. Solution = (1, -6) ONE SOLUTION

4. Solution = (-4, -1) ONE SOLUTION

p.s i attached the graphs for problems 3 and 4. The first picture is for problem 3 and the second picture is for problem 4

I really hope this helped :)

Which of ghe following is equivalent to (x+4)(3x^2+2x)?

Alexxandr [17]

The given expression is

$(x+4)(3x^2 +2x)$

And in the second factor, x is common. So on taking x out, we will get

$(x+4)(x)(3x+2) = x(x+4)(3x+2)$

We can expand it by distributing , that is

$(x+4)(3x^2 +2x) = x(3x^2 +2x) +4 (3x^2 +2x)$

$= 3x^3 +2x^2 + 12x^2 +8x$

Combining like terms,

$= 3x^3 +14x^2 +8x$

And that's the expanded form ., and the given expression can also be written in that way .

Find the solution to the system of equations: x + 3y = 7

tigry1 [53]

Answer:

(-2,3)

Step-by-step explanation:

Doing it the way you did and working out the problem you substituted 3 into, x+3(3)=7, 3(3) is 9 and then you subtract 9 from both sides.

7-9=-2

x=-2

Then all you have to do is put it into ordered pairs.

(x,y)

(-2,3)
