On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how much she raised in one day.
Answers
Answer: Hello daema, let's let x be the goal and c be the collection per day.
x - 45 + c = x + 5 is the answer so now let's talk about how we did that.
So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.

paz and her scout troop makes 325 granola bars for a fundraiser. four granola bars are put in each bag. paz says that there will not be any left over. find and correct her mistake.
Answers
Answer:
Her mistake was in how many bags would be able to equally hold 4 bars.
325/4 is 81.25, which would mean there needs to be 82 bags, in which you wouldnt be able to hold 4 each equally.
A better option for Paz is to put 5 bars in each bag as 325 is an even multiple of 5. As such would result in the bag count being brought down to 65 bags to evenly hold all of the bars.

Function g is an exponential function passing through points (3,-53) and (5,-41). Which statement is true over the interval [3,5]?
Answers
Answer: The function is increasing in the given interval.
Step-by-step explanation:
The options are not given, so i will answer in a general way.
We have an exponential function g(x) such that:
g(3) = -53
and
g(5) = -41
From this we can only conclude that in the interval [3, 5] the function is increasing, because g(5) > g(3) and the general form of a exponential function is:
g(x) = A*(r)^x + C
Notice that we have two equations and 3 variables in the equation, this means that we can not find an exact solution for g(x) (we need the same number of independent equations than variables)
Then we can not conclude anything else for g(x)

Step-by-step explanation: This is a rotation. An easy way to tell the difference between a rotation and a reflection is that the order of the points will not change in a rotation. For this problem, pre-image ABCD is still in the order of ABCD when mapped to the image. (You can still follow along the points in that order). When something is reflected, the points swap orders and you would not be able to follow the points in order.
Now that we know this is a rotation, Notice A’ B’ C’ and D’ are all left of the pre-image. This means the mapped image moves counter clockwise.
A rectangle has an area of 2x2 - 19x +45 ft? What are the dimensions of the rectangle? (hint: factor)
Answers
The dimensions of the rectangle will be (2x - 9)(x - 5).
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the area of the rectangle is represented by a quadratic equation 2x² - 19x +45.
The dimensions of the rectangle will be the factors of the quadratic equation.
2x² - 19x + 45
2x² - 10x -9x + 45= 0
2x( x - 5 )-9(x - 5)= 0
( 2x - 9 ) ( x - 5 ) = 0
Therefore, the dimensions of the rectangle will be (2x - 9)(x - 5).
