Write an explicit formula for the sequence 7, 2, –3, –8, –13, find the 14th term
Ilia_Sergeevich [38]

The 14th term is equal to -44.

y = 12 - 5x

The sequence can be represented by this function.

Each term is being subtracted by 5.

Using this function we can find the 14th time.


y = 12 - 5(14)

y = 12 - 56

y = -44

What is the solution of -2x-2y=4 and x+5y=10
AysviL [449]
-2x - 2y = 4
x + 5y = 10

It looks like the method it would be easiest to use to solve this system is substitution. To use substitution, let us isolate x in the second equation:

x + 5y = 10
x = -5y + 10

---

-2x - 2y = 4
-2(-5y + 10) - 2y = 4
10y - 20 - 2y = 4
8y - 20 = 4
8y = 24
y = 3

Now we can substitute back into the second equation to find x:

x + 5y = 10
x + 5(3) = 10
x + 15 = 10
x = -5

Finally, to check our work:

-2(-5) - 2(3) = 4   -->   10 - 6 = 4   <--True
-5 + 5(3) = 10   -->   -5 + 15 = 10   <--True

Answer:
y = 3
x = -5

HELP ASAP!<br><br> convert to slope-intercept form with steps please :)<br><br> 6x &gt; 2y = 5
luda_lava [24]

Answer:

y < 3x + \frac{5}{2}

Step-by-step explanation:

6x > 2y - 5

<em>Adding 5 to both sides</em>

=> 6x + 5 > 2y

<em>=> </em>2y < 6x+5

Dividing both sides by 2

=> y < \frac{6x+5}{2}

=> y < \frac{6x}{2} + \frac{5}{2}

=> y < 3x + \frac{5}{2}

This is the required slope intercept form in the form y = mx+b
