Answer: 203.5mg and 322.5mg

Step-by-step explanation:

Let represent two serving of Mc Donald quarter pounds with = m

Let three Burger King whopper = b

given:

1). m + b = 300 + 395......equation 1.

1). m + b = 695.

And

2). 3m + b = 288.......... equation 2.

• Using Elimination method, Multiply both sides of eqn.(1) and (2)by 3. then

-3m + 3b = 2084

9m + 3b = 864

Subtract equation (1) from (2).

6m = 1221

Divide both sides by -6

m = 203.5

Substitute (m) into equation 1

3m + b = 288.

3(203.5) + b = 288.

610.5 + b = 288

b = 610.5 - 288

b = 322.5

Two servings of Mc Donald quarter pound has 203.5mg of cholesterol.

Three servings of whopper has 322.5mg of cholesterol.

deposit of $1644.50 is (gain)

check written and deposit are (loses)  subtracted


so total of 3 checks :-   190$   +  45$  +  7.50$   =   242.50$

total of 4 debit cards :-    30$  +  5.59$  +  7.20$  + 21.30$  = 64.09$

total lose amount ( credits + debits )  =   242.50 $  +  64.09$ =  306.59$


Ending balance = Total amount - total loses =  

         1644.50$ -  306.59 $ =  1337.91$

Which of the following statement(s) describes the rate of change of f over the interval 1.5 ≤ x ≤ 3? Select all that apply.
Vesnalui [34]

2 Answers: Choice B and Choice C

The rate of change is 2.

The rate of change is constant.

======================================================

Explanation:

The first point on the left is when x = 1.5 and it has a height of y = 1

The point (1.5, 1) is on the line.

So is the point (3,4) for similar reasoning.

Compute the slope between those points

m = (y2-y1)/(x2-x1)

m = (4-1)/(3-1.5)

m = 3/(1.5)

m = 2

The slope is 2, which is the same as saying the rate of change is 2. This only applies when x > 1 of which the interval 1.5 ≤ x ≤ 3  is a part of.

Since the slope stays at 2 on the interval 1.5 ≤ x ≤ 3, this means we consider the slope to be constant. If the curve bended at all on this interval, then it wouldn't be a constant slope.
