Answer:
10a + 6
Step-by-step explanation:
3a + 4 + 2a - 1
5a + 3
2( 5a + 3)
10a + 6
1/8 = 0.16/x...1 gal to 8 pts = 0.16 gal to x pints
cross multiply
(1)(x) = (8)(0.16)
x = 1.28 pints per second
1.28 * 25 = 32 pints are dispensed in 25 seconds
Lets put the equation into slope intercept form
y+2=-3(x-5)
y+2=-3x+15
subtract 2 from both sides
y=-3x+13
The formula for slope intercepts form is
y=mx+b where m=slope and b=y-intercept
So -3 is the slope
Answer=-3
Solution of 9x+8y=26 and 3x+2y=9 are given by
.
We have to plot the graphs of the given two lines or curves, then we have to find the intersection point(s) of the curves or lines. That point is the solution for the system of the equations.
Given equations are,
.................(1)
...................(2)
Now multiplying 3 with (2) and then subtracting (1) from that we get,

Substituting the value of y in (1) we get,

Also if we draw the graphs of the given equations by using graphing calculator we get,
Here in the graph we can see that the lines represented by the given equations intersects each other at point
.
Hence the solution is

Combine the 2 equations:
3x-2y=12
-3x+8y=-6
---------------
6y = 6, which tells us that y=1.
Now subst. 1 for y in the 2nd equation: -3x +8(1) = -6.
Then 14=3x, and x = 14/3.
The solution is (14/3,1).
