Answer:
The amount of Data needed for monthly charge to be same = 5 GB
Step-by-step explanation:
Given as :
<u>Cell Phone plan A </u>
Monthly rent of $ 20 per month
The charge on use of Data is $2 per GB
<u>Cell Phone plan B</u>
Monthly rent of $ 15 per month
The charge on use of Data is $3 per GB
Now from given two data plan ,
To make the monthly charge on Internet for both the cell phone to be same
Let the amount of data needed be x GB
So, A|C to question :
20 + x × 2 = 15 + x × 3
Or, 20 - 15 = (3x - 2x)
Or, 5 = x
∴ x = 5 GB
Hence The Amount of Data needed to make charges same is 5 GB Answer
Answer:
<u>The system has two solutions:</u>
<u>x₁ = 5 ⇒ y₁ = -10</u>
<u>x₂ = -2 ⇒ y₂ = 11</u>
Step-by-step explanation:
Let's solve the system of equations, this way:
y = -3x + 5
y = x ² - 6x - 5
Replacing y in the 2nd equation:
y = x ² - 6x - 5
-3x + 5 = x ² - 6x - 5
x ² - 3x - 10 = 0
Solving for x, using the quadratic formula:
(3 +/- √(9 -4 * 1 * -10))/2 * 1
(3 +/- √9 + 40)/2
(3 +/- √49)/2
(3 +/- 7)/2
x₁ = 10/2 = 5
x₂ = -4/2 = -2
x₁ = 5 ⇒ y₁ = -10
x₂ = -2 ⇒ y₂ = 11
<u>As we can see the system has two different solutions</u>
Answer:
2 2/3 cup apple juice
Step-by-step explanation:
The scale factor is 1/22.
In the drawing, the height of the school shows 1.6 feet.
In order for us to know the actual height, we can have it as.
1.6 = Height of school * (1/22)
1.6 = Height of school / 22
Height of school = 35.2
So the actual height of the school is 35.2 feet.
