Answer:
The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330
Step-by-step explanation:
<u><em>The correct question is</em></u>
Birds burgers barn sold <em>495 hamburgers</em> today. The number sold with cheese wise half the number sold without cheese. How many of each kind were sold?
Let
x -----> the number of hamburgers sold with cheese
y -----> the number of hamburgers sold without cheese
we know that
-----> equation A
----> equation B
substitute the equation B in equation A and solve for y
Find the value of x
therefore
The number of hamburgers sold with cheese was 165 and the number of hamburgers sold without cheese was 330
Answer:
The domain ⇒ x ∈ real number
The range ⇒ y ≥ -3
The y-intercept ⇒ (0 , -1)
Step-by-step explanation:
∵ y = 2Ix - 1I - 3
∴ y = 2(x - 1) - 3
∴ y = 2x - 2 - 3 = 2x - 5 ⇒ positive slope
∴ y = 2(-x + 1) - 3
∴ y = -2x + 2 - 3 = -2x - 1 ⇒ negative slope
∴ 2x - 5 = -2x - 1 ⇒ 4x = 4 ⇒ x = 1
∴ Y = 2(1) - 5 = -3
∴ The two lines intersect each other at (1 , -3)
∴ The domain is x ∈ real number
∴ The range is y ≥ -3
∴ The y-intercept = -1 ⇒ (0 , -1)
It’s b and don’t open the link above they take you’re information
First, you need to turn it into a fraction by doing the multiplication. 6/1 × 3/20 which is 18/20. then you simplify it to get 9/10. 9/10 is your answer
