Answer:
awnser is 1718
Step-by-step explanation:
Answer:
You divide by - 1
Step-by-step explanation:
-x divided by - 1 is x
5 divided by - 1 is - 5
x > - 5
$88.00 minus $70.00 base fee is $18.00 then you divide that by $4.50.
The answer is 4 liters.
Answer:
B
Step-by-step explanation:
Let's create an equation in point-slope form, which is:
, where
is the point and m is the slope.
Here, our point is (-2, 7) and our slope is m = -5 so plug these in:
![y -7=-5*(x-(-2))](https://tex.z-dn.net/?f=y%20-7%3D-5%2A%28x-%28-2%29%29)
![y -7=-5*(x+2)](https://tex.z-dn.net/?f=y%20-7%3D-5%2A%28x%2B2%29)
Now, if (a, 2) lies on this line, then it should satisfy the equation. So plug in a for x and 2 for y:
2 - 7 = -5(a + 2)
-5 = -5(a + 2)
Divide by -5:
1 = a + 2
Subtract 2 from both sides:
a = -1
Thus, the answer is B.
Hope this helps!
Let's actually find the solution of
<span>2x - 6y = 8
-x + 3y = 10
Let's use the addition/subtraction method. Multiply the 2nd equation by 2, obtaining
</span> 2x - 6y = 8
-2x + 6y = 20
--------------------
0 + 0 = 28
Since this can never be true, the system of linear equations
2x - 6y = 8
-x + 3y = 10
has no solution.
