To solve this problem you must apply the proccedure below:
1. Let's call:
x: hot dogs.
y: hamburguers.
2. Then, you must make a system of equations, as below:
5x+4y=12.25 (i)
4x+5y=12.50 (ii)
3. Now, you can solve the system of equation as below:
5x+4y=12.25
x=(12.25-4y)/5
4x+5y=12.50
4((12.25-4y)/5)+5y=12.50
y=1.5
4x+5y=12.50
4x+5(1.5)=12.50
x=1.25
4. Therefore, the answer is:
The cost of one hot dog is $1.25 and the cost of one hamburguer is $1.50
You have to subtract 3.2 from 3.5 to get x. 0.3+ 3.2=2.5 so x=0.3
The exponential parent function is D
A Because y=mx+b So if you graphed it then it would be A
Answer:
v = -16
Step-by-step explanation:
<u>→Distribute the 5 to (-7v - 11):</u>
14 - 10v + 11 = 20v - 35v - 55
<u>→Add like terms:</u>
25 - 10v = -15v - 55
<u>→Add 15v to both sides:</u>
25 + 5v = -55
<u>→Subtract 25 from both sides:</u>
5v = -80
<u>→Divide both sides by 5:</u>
v = -16
