Hey there! I'm happy to help!
This is slope intercept form: y=mx+b, where m is the slope and b is the y intercept. The slope is what is multiplying x. In our case, 2.83 is multiplying x, so 2.83 is the slope.

In the 21st century, people measure length in feet and meters. At various points in
history, people measured length in hands, cubits, and paces. There are 9 hands in 2
cubits. There are 5 cubits in 3 paces.
a. Write an equation to express the relationship between hands, h, and cubits, c.
b. Write an equation to express the relationship between hands, h, and paces, p.
Answer:
The answer to b is 22.5 hands is 3 paces
Step-by-step explanation:

We want to find equations for changes of units, which allow us to change the units of a given measure to an equivalent value.
a) [tex]C = H*\frac{2c} {9h}[/tex]
b) [tex]P = H*\frac{6p}{45h}[/tex]
--------------------------------
We know two relations:
9 hands = 2 cubits.5 cubits = 3 paces.a) We want to find an equation to express the relationship between hands, h, and cubits, c.
Let's start with the relation:
9 hands = 2 cubits
we can rewrite:
[tex]1 = (2 c)/(9 h)[/tex]
Now suppose that we have a measure in hands, H.
If we multiply this measure by 1, we do not affect the measure, then we have:
[tex]H = H*1 = H*\frac{2c}{9h}[/tex]
Notice that we are dividing by hands, so we are cancelling the hands units, and we are multiplying by cubits, so we changed the units.
Then we can define C as the equivalent measure to H, such that C is in cubits.
[tex]C = H*\frac{2c}{9h}[/tex]
b) Similar to before.
Again, let's use H as a measure in hands.
With the relation:
[tex]C = H*\frac{2c}{9h}[/tex]
We change from hands to cubits.
Now with:
5 cubits = 3 paces.
We can write:
1 = 3p/5c
If we multiply our measure in cubits by the above fraction, we can change the units from cubits to paces, so we will have that P, the equivalent measure to H in paces is given by:
[tex]P = C*\frac{3p}{5c} = H*\frac{2c}{9h}*\frac{3p}{5c}= H*\frac{6p}{45h}\\\\P = H*\frac{6p}{45h}[/tex]

2y - 3x = -27
5y + 3r = 6
X= ?
Y= ?
Answer:
y = -3 x = 7
Step-by-step explanation:
2y - 3x = -27
5y + 3x = 6
3x cancels.
7y = -21
y = -3
Substitute y in 2y - 3x = -27
2(-3) - 3x = -27
-6 - 3x = -27
-3x = -21
x = 7

The situation that is best modeled by a discrete graph is the daily records of the distance of each hotel from home during a cross-country trip. the height of a wave over time. the speed of a motorcycle over the distance it travels. the body temperature of an athlete during a workout.
Answer:A
Step-by-step explanation: the other dude is wrong
and if im right mark me brainiest
The best modeled by a discrete graph is body temperature of an athlete during a workout.
The correct option is (D)
What is Discrete graph?A discrete graph is one with scattered points. They may or may not show a direction or trend. They don't have data in between the points already given.
A continuous graph has a line because there is data in between the points already given.
So, according to the condition the best modeled discrete graph is body temperature of an athlete during a workout.
This is because for the body temperature measure, we only need to measure it once in a while.

2. Mourette is a member of her high school golf team. She hits a golf ball
off the ground with an initial upward velocity of 60 meters per second.
a. Write a formula describing the height h of the ball (in meters)
after t seconds.
b. After how many seconds, to the nearest tenth, will the
golf ball land on the ground?
c. What is the maximum height the golf ball reaches?
please help!
Answer:
a. h = 60t − 4.9t²
b. 12.2 seconds
c. 183.7 meters
Step-by-step explanation:
a. Given:
y₀ = 0 m
v₀ = 60 m/s
a = -9.8 m/s²
y = y₀ + v₀ t + ½ at²
h = 0 m + (60 m/s) t + ½ (-9.8 m/s²) t²
h = 60t − 4.9t²
b. When the ball lands, h = 0.
0 = 60t − 4.9t²
0 = t (60 − 4.9t)
t = 0 or 12.2
The ball lands after 12.2 seconds.
c. The maximum height is at the vertex of the parabola.
t = -b / (2a)
t = -60 / (2 × -4.9)
t = 6.1 seconds
Alternatively, the maximum height is reached at half the time it takes to land.
t = 12.2 / 2
t = 6.1 seconds
After 6.1 seconds, the height reached is:
h = 60 (6.1) − 4.9 (6.1)²
h = 183.7 meters

How many ink cartridges can you buy with 150 dollars if one cartridge costs 15 dollars ?
Answer:
10
Step-by-step explanation:
Very easy equation if you know how to do it. All you need to do is divide your total amount of something (in this case "150" as that's our amount of "money we're given") by whatever the price or amount is. (In this case 15. Each cartridge costs $15. I'm not amazing at explaining things like this.. Sorry about that. If you have any questions about this feel free to let me know!)
So to put it "all together":
150 ÷ 15 = 10.
10 is your answer.

The USDA reported that in 1990 each person in the United States consumed an average of 133 pounds of natural sweeteners. They also claim this amount has decreased by about 0.6 pounds each year. a. If 1990 could be considered year zero, which of the above numbers represents the slope and which represents the y intercept? b. What is the equation of the line of best fit using the slope and y-intercept above? c. Predict the average consumption of sweeteners per person for the year 2005.
Answer:
The problem implies that we want to write the (average) amount of natural sweeteners consumed per person as a function of time. Let y represent the (average) amount of natural sweeteners consumed per person (in pounds), and let x represent the time measured in years since 1990. That is, x = 0 represents 1990. If y is a linear function of x, then we can use the slope-intercept form y = mx + b (where m is the slope and b is the y-intercept) to write the function.
The slope can be interpreted as the rate of change of y with respect to x, which in this case means the change in consumption of natural sweeteners per year. The statement that consumption has decreased by 0.6 pounds per year tells us that the slope is m = -0.6 Also, the y-intercept is the same as the y-value of the function when x = 0. (In our case, that means time 0, that is, 1990.) Therefore the y-intercept is b = 133. Hope that helps! Let me know if you have any further questions.

A cell phone company charges $4 per GB beyond
20GB in a month. The monthly plan is $59.99, and
the bill for January is $75.99. How many GB were
used in that month?
Answer:
25GB was used that month
Step-by-step explanation:
Here, we want to calculate the GB used for the month.
Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.
The extra charges is thus $75.99 - $59.99 = $20
Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5
So the total GB for that month is 20 + 5 = 25GB

-14-7(9v+3)=13v+41
Answer:
v=−1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−14−7(9v+3)=13v+41
−14+(−7)(9v)+(−7)(3)=13v+41(Distribute)
−14+−63v+−21=13v+41
(−63v)+(−14+−21)=13v+41(Combine Like Terms)
−63v+−35=13v+41
−63v−35=13v+41
Step 2: Subtract 13v from both sides.
−63v−35−13v=13v+41−13v
−76v−35=41
Step 3: Add 35 to both sides.
−76v−35+35=41+35
−76v=76
Step 4: Divide both sides by -76.
−76v
