Answer:
6
+ 35x + 36
Step-by-step explanation:
(2x + 9) (3 x+4) = 6x*x + 36 + 27x + 8x = 6xx + 36 + 35x
= 6 + 35x + 36
<span>6x+9y = 10500
x+y = 1480
Using elimination I get:
6x + 9y = 10500
-6x-6y = -8880
Add the 2 equations and I get 3y = 1620
Divide both sides by 3 and I get y = 540
Substitute that back in to 6x+9y = 10500.
I get that 6x+9*540 = 10500
9 * 540 = 4860
Subtract 4860 from both sides and I get 6x = 5640
Divide both sides by 6 and I get x = 940
So there must have be 940 children and 540 adults</span>
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using rise/run (y2 - y1) / (x2 - x1)
Plug in the points:
(36 - 21) / (15 - 10)
15/5
= 3
Next, plug the slope and a point into the equation y = mx + b to find b (y-int)
y = mx + b
21 = 3(10) + b
21 = 30 + b
-9 = b
Then, plug this into the equation, as well as the slope:
y = 3x - 9
