Lets make the graph of our systems of equations:

The blue line correspond to the equation x-y=3 and the red one correspond to 7x-y=-3. The lines intersect at point (-1,-4), then, the solution of the system is (-1,-4).

The square of a number plus three times the number is 70. find the numbers.
Harrizon [31]

Answer:

Step-by-step explanation:

The equation for that is

x^2+3x=70

If we subtract over the 70, we have a quadratic that we can factor to solve for the values of x that will make that equation true.

x^2+3x-70=0

Now we need the factors of 70 that will either add or subtract to give us the linear term of 3. The factors of 70 that will work are 10 and 7. 10 times 7 is 70, and 10 - 7 = 3:

x^2+10x-7x-70=0 and now we will factor by grouping:

(x^2+10x)-(7x-70)=0 and factor out what's common:

x(x+10)-7(x+10)=0

The factor (x + 10) is common, so we will now factor that out:

(x+10)(x-7)=0

By the Zero Product Property, either x + 10 = 0 or x - 7 = 0, so x = -10 or 7

Those are the 2 numbers that will work.

(-10)^2+3(-10)=70 simplifies to

100 - 30 which does in fact equal 70. OR

(7)^2+3(7)=70 which simplifies to

49 + 21 which also equals 70.

So you're done!

Simplify <br> 3(x - 6) - 4(x + 3).<br> A)-x - 30<br> B)-x - 9<br> C)-x - 6 <br> D)-x - 30
morpeh [17]

Answer:

-x-30

Step-by-step explanation:

<em>first you need to </em><em>distribute</em><em>:</em>

<em>3(x)+3(-6) -4(x)+ (-4)(3)</em>

<em>Then you </em><em>multiply:</em>

<em>3x+(-18)-4x+(-7)</em>

<em>then you </em><em>combine like terms:</em>

<em>3x-4x= -1x </em>

<em>-18+(-7)= -25</em>

<em>simplified:</em>

<u><em>-1x-30</em></u>

I need help. This isn’t school related but it’s for my early college essay. The topic is why is early college a good fit for me?
Diano4ka-milaya [45]

Answer:

Early college provides high school students the ability to get a sneak-peak into what college is like as a whole. Credits, professors, homework, campus and friends don't need to be intimidating topics anymore.

What number goes in the box in the followng sequence 5 11 23 ? 95 191​
Alina [70]

Answer:

47

Step-by-step explanation:

The number that should go after 23 is 47.

The pattern seems to be (n * 2) + 1, where n is the value of the previous number.

We start with the number 5:

5

(5 * 2) + 1  = 11

11

(11 * 2) + 1 = 23

23

(23 * 2) + 1 = 47

47

... and so on

The pattern should continue as follows.

Hope this helps!
