<span>1. Through: (5, -1) and (-5, -4) 
slope = (-4 +1)/(-5 -5) = -3/-10 = 3/10
y = mx + b
-1 = 3/10 (5) + b
-1 = 3/2 + b
b = -1 -3/2
b = - 5/2
equation

y = 3/10x - 5/2

</span><span>2. Through: (-3, 2) and (0, -1) 
</span><span>slope = (-1 - 2)/(0 +3) = -3/3 =-1
passing thru </span>(0, -1) so b = -1
<span>
equation
y = -x - 1

If four times the sum of a number and 3 is divided by 2, the quotient is 0: find the number
AveGali [126]

The other number is -3.

Step-by-step explanation:

Step 1; First we develop formulae for the given information. A number is added with 3 and the resulting sum is multiplied by 4. This number is then divided by 2 and the quotient is 0. Assume the unknown number is x, then the given information is as follows

The quotient of \frac{4(x+3)}{2} is 0. So \frac{4(x+3)}{2} = 0.

Step 2; Now we solve the above equation. The denominator is taken to the RHS and the RHS remains zero.

\frac{4(x+3)}{2} = 0, 4(x+3)= 0, 4x+ 12 = 0, 4x = -12, x = \frac{-12}{4} = -3.

So the other number is -3.

the solution:

-4.5 t = 75-120

-4.5t = -45

t = -45/(-4.5) = 10 minutes
