Answer:
2
Step-by-step explanation:
Answer:
the solution is (4, 1).
Step-by-step explanation:
The goal here is to "solve this system of linear equations." You need to share that along with the equations.
We can begin the solution by substituting 3y + 1 for x in the second equation:
2(3y + 1) + 4y = 12
Performing the multiplication, we get 6y + 2 + 4y = 12, or 10y = 10.
Then y must be 1.
Substituting 1 for y in the first equation, we get x = 3(1) + 1 = 4
Thus, the solution is (4, 1).
On a cube there are 6 sides with the numbers: 1,2,3,4,5,6.
so probability of 1 role to get a 4 would be 1/6
The probability of getting a 4 on 240 roles would be 40 times because:
1/6=x/240
240=6x
divide by 6
40 is final answer
Let x = 30% y=16%
We need 5 liters of 27.2% acid
A) x + y = 5
B) .30 x + .16y = 5 * .272
Multiplying A by -.30
A) -.30 x - .30y = -1.5 then adding to B
B) .30 x + .16y = 1.36
-.14y = -.14
y = 1 liter 16%
x = 4 liters 30%
This function is Exponential
- Reason: Exponential graphs tend to get very big quickly, and though they start out smaller than polynomial functions or vice versa
Hope that helps!
