Answer:
The zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.
Step-by-step explanation:
From the information provided, you can say that the result of adding up the African elephants cost to feed per day for the number of African elephants plus the Asian elephants cost to feed per day for the number of Asian elephants would be equal to £1000, which can be expressed as:
11x+9y=1000, where:
x is the number of African elephants
y is the number of Asian elephants
Now, as the statement indicates that the zoo has an equal number of African elephants and Asian elephants, this means that x=y and you can replace y with x and solve for x:
11x+9x=1000
20x=1000
x=1000/20
x=50
According to this and considering that the zoo has an equal number of African elephants and Asian elephants, the answer is that the zoo has 50 African elephants and 50 Asian elephants which means that there are 100 elephants.
The answer is C
12 * 4 = 48, 180 - 48 = 132
I hope this helps :)
Answer:
choices A, B, and D are all true
choice C is false
Step-by-step explanation:
Choice A is true because both functions shown on the graph have exactly one asymptote at about y=1.
Choice B is true because well, the reason Choice C is not true. logarithmic graphs and exponential graphs look very similar. However, exponential graphs get very close to the x-axis but never actually touch it. In this graphing, the blue function crosses the x-axis, so it cannot be an exponential function. The only other function that has graphs that look like this is a logarithmic function, so Choice B is correct and Choice C is not correct.
Once again, Choice C is not correct because the blue graph crosses the x-axis and exponential functions never actually touch the x-axis no matter how close they get to it.
Choice D is correct because the red graph has been reflected over the x-axis and shifted upward, and the blue graph has been reflected across the y-axis and shifted to the right.
Answer:
Step-by-step explanation:
x^2=+5X=300
Let
x = the width of the rectangle
y = the length of the rectangle
we know that
the area of the rectangle is equal to
A=xy ___ equation 1
y=x+5 ___equation 2
substitute equation 2 in equation 1
------> given problem
so
the area of the rectangle is equal to
Solve the quadratic equation
we know that
The formula to solve a quadratic equation of the form is equal to
we have
so
substitute in the formula
The solution is
Find the value of y
y=x+5
