A = b is given to us
Multiply both sides by c to get
a = b
a*c = b*c
The rule to multiply both sides by c is the multiplicative property of equality
Then on the right side, replace c with d. This replacement is possible due to the fact that c = d. This is using the substitution property.
So we go from
a*c = b*c
to this
a*c = b*d
YES!!! 2.78778777 is an irrational number because it has endless numbers, and a irrational number cant be put as a fraction but rational numbers can be put as a fractio!!
Answer:
Step-by-step explanation:
so first you need to make a equation
since we are trying to find out the amount of rides we can make that stand for x so..
we can first write it as 2.50x
(x = the numbers of rides)
since the entree fee is 17 dollars but they are two kids we have to times 17 by 2 giving us 34 we can add 34 dollars to the equation
34 + 2.50x
alex and kendra have only $51.50 dollars and they cant spend more then that so that means the whole equation has to equal $51.50
34 + 2.50x = 51.50
since we are trying to find the number of rides we can subtract 34 on both sides giving us
2.50x = 51.50 - 34
2.50x = 17.50
then we solve for x which you can divde 2.50 on both sides
x = 17.50 /2.50
x = 7
Given:
The function is
To find:
The domain, range, and intercepts of the function.
Solution:
We have,
It is a linear function, and domain and range of these types of functions are all real numbers.
Put x=0 in f(x), to find the y-intercept.
So, the y-intercept is 11.
Put f(x)=0 in f(x), to find the x-intercept.
Divide both sides by 7.
So, the x-intercept is 
.
Therefore,
