If you make the denominators similar, you get
6/8 and 7/8
6/8 is smaller, so no, 3/4 isn't bigger than 7/8

First, you have to find a common denominator. 4 times 2 equals 8. So, multiply 3 by 2 and you get 6. 3/4 is smaller than 7/8, not bigger.

Answer:

(-3,-1)

Step-by-step explanation:

You can graph both of the points on desmos, and then look at the slope from p1 to the midpoint. so you can get the slope, and use it to get the p2. the slope is -4/6. So you get that answer.

The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y – 4 = (x – 8). What is the slop

Elenna [48]

The slope-intercept formula can be written as follows:

y = mx + b

The variable "m" represents the slope of the line, while "b" represents the y-intercept. We'll start with the y-intercept.

We know that the y-intercept can be defined as the value of "y" when "x" is equal to zero. To do this, we will need to find point (0,y). The original problem gives us two points, one of which is (0,2). Because "x" is equal to zero, we know that the y-intercept is 2. Substitute this value into the slope-intercept formula:

y = mx + 2

Now we need to find the slope. Slope can be defined as the "rise" of the line over the "run" of the line. In other words, calculate the change in y-value over the change in x-value. To do this, we will use the "x" and "y" values of the two points given in the problem.

Starting with the y-values (rise), we have 2 and 4. The difference between these two values is 2. Moving on to the x-values (run), we have 0 and 8. The difference between these two values is 8. Now put rise over run and substitute this value into the slope-intercept formula:

y = (2/8)x + 2

Now simplify the right side of the equation:

y = (1/4)x + 2

We now have a complete slope-intercept formula of the line.

I hope this helps!

Answer:

See solution :)

Step-by-step explanation:

Let us first analyse our information given. The question tells us that each person, (i.e. Jamie and Stella) should pay $600 upfront. Thus, our first constraint (lets call it $T$ ) is that any total amount of money must be equal or more than $600, which in maths notation reads:

$T\geq 600$

where $\geq$ means More or Equal to.

We also know that Jamie washes care for $25 dollars and if represented in math notation, we can say that for every car (denoted by) $x$ , Jamie makes $25, thus for Jamie we have:

J: $25x$

Similarly we know that Stella makes pecan pies and for each pie she sells she makes $15, so we can say that for every pecan pie (denoted by) $y$ , Stella makes $15, thus for Stella we have:

S: $15y$

However, we also know that Stella does not have enough supplies for more than 40 pies, which puts a constraint on the amount of money she can make by selling pecan pies. Therefore we can now say that

$15y$ is true, for $y\leq 40$

where $y\leq 40$ is the constraint on Stellas possible profits and $\leq$ means Less or Equal to.

Now lets start answering the questions:

Part 1: Write a constraint (an inequality) to represent how much money Jamie needs for his trip.

Answer: $25x$

*provided that $25x\geq 600$ (in order to make the neccesary profit)

Part 2: Write a constraint (an inequality) to represent how much money Stella needs for her trip.

Answer: $15y\geq600$ and $y\leq40$

Part 3: Write a constraint (an inequality) to represent the relationship between Jamie's earnings and Stella's earnings.

Answer: Since Stella can not make more than 40 pies, the solution intersection between Jamie and Stella is $y\geq 40$ (Jamie) ∩ $y\leq40$ (Stella), thus y=40.

Part 4: Can Stella afford to sign up for the trip with the money she earns? Explain your answer and show any work that might support your answer.

Answer: We know that Stella's pie making is denoted by $15y$ , and the total amount needed for the trip upfront is denoted by $T\geq 600$ therefore to find if Stella can afford to sign up, we need to find the amount of pies Stella needs to produce, in order to make a profit of at least $600. Thus we write:

$15y\geq 600\\y\geq \frac{600}{15}\\ y\geq 40$

Since the number of pies Stella needs to make, to gain a profit of $600 is 40 pies, and we know that Stella can make a maximum of 40 pies with the supplies she already has, we can conclude that Stella can make the necessary money to make her trip to Washington!
