the french club is sponsoring a bake sale. if their goal is to raise at least $135, how many pastries must they sell at $3.00 ea
2 answers:
Answer:
45 or more
Step-by-step explanation:
If x is the amount of pastries they sell, we need to multiply it by $3.00 to know how much they raise. Total earnings: $3.00x
They need to raise at least $135, that is $135 or more.
So, $3.00x has to be greater than $135 or equal.
Written as an inequality is:
$3.00x $135
We divide both sides by $3.00 and we have:
x $135/$3.00 = 45
Therefore, they need to sell 45 or more pastries to meet the goal.

Answer:
4
Step-by-step explanation:
Here is the complete question: Use the distributive property to fill in the blanks below
As per Distributive property of multiplication, a number is multiplied to the number inside the parenthesis separately, then adding or substracting the product of the number to get result, which is equal to the number multiplied directly to the sum of the number inside the parenthesis.
As we in given question we can see:
If we multiply 4 separately to 2 and 1 as per distributive property of multiplication.
∴
Hence, 4 will be the number in the blank.
Answer:
So we have found algebraically that g(x) is <em><u>not</u></em> the inverse of f(x).
We can see graphically from the graph attached that the two lines are parallel and so g(x) cannot be the inverse of f(x).
Step-by-step explanation:
i) f(x) = y = 2x + 3
replacing x with y and y with x we get
therefore x = 2y + 3
therefore
It is given that g(x) = 2x - 3.
So we have found algebraically that g(x) is <em><u>not</u></em> the inverse of f(x)
ii) we can see graphically from the graph attached that the two lines are parallel and so g(x) cannot be the inverse of f(x)
