Noir drove from the Dead Sea up to Amman, and her altitude increased at a constant rate. When she began driving her altitude was 400 meters below sea level. When she arrived in Amman 2 hours later, her altitude was 1000 meters above sea level. Let y represent noir’s altitude in meters relative to sea level after x hours.
Answer:
y(x) = -400 m + (700 m/hr)x
Step-by-step explanation:
Let y = 0 represent sea level. Noir's initial altitude was -400 m. In two hours she went from -400 m to +1000 m, a positive change of 1400 m. Thus, the rate of ascent was m = slope = (change in altitude) / (change in time), or
rate of ascent = 1400/2 m/hr = 700 m/hr
Thus, an equation describing her altitude relative to sea level after x hours is
y(x) = -400 m + (700 m/hr)x, where x is the number of hours of driving completed. This formula correctly predicts the altitude after two hours:
y(2) = -400 m + (700 m/hr)(2 hr) = 1000 m above sea level.

Help it’s confusing please
Answer:
She had $150 in the beginning before she bought the swimming items.
Step-by-step explanation:
You have the right numbers for the equation but you also times the money she had in total.
The equation is x-3(44)=18
44 is the total for one daughter and you times that by three to get for three duaghters.
Then you multiply -3 and 44 which is -132.
Which would be x-132=18
Now you would move -132 to the other side which would be +132 →x=18+132
x=150

Answer:
vertex = (7, - 2 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = x² - 14x + 47
Using the method of completing the square
add/subtract ( half the coefficient of the x- term)² to x² - 14x
y = x² + 2(- 7)x + 49 - 49 + 47
= (x - 7)² - 2 ← in vertex form
with vertex = (7, - 2 )
Select all the parallelograms.
Step-by-step explanation: In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
A line passes through the points (4, 6) and (8, 7). What is its equation in point-slope form?
Hello there! :)
First, let’s find the slope.
We can find it using this formula:
m=y2-y1/x2-x1
m=7-6/8-4
m=1/4
So the slope is 1/4.
Now, we can use the point-slope formula:
y-y1=m(x-x1)
y-6=1/4(x-1/4)
Hope it helps. :)

Answer:
18.725
Step-by-step explanation:
4 5/8 = (4*8 + 5) /8 = 37/8
10 7/10 = (10*10 + 7) / 10 = 107/10
3 2/5 = (3*5 + 2) / 5 = 17/5
lcm of 8, 10, 5 is 40
37/8 + 107/10 - 17/5
= (37*5 + 107*4 - 17*8) / 40
= (185 + 428 + 136) / 40
= 749/40
= 18.725
I hate maths pleas help
Answer:
These should be the answers you are looking for.
A: 62
B: 8.9
C: 2.8
This should be correct, but please tell me if it isnt.
Explanation:
The simplest way to figure this out is by counting how many marks there are on the number line. If the numbers are betweeen 1 and 2 on a number line for example, youll want to use decimals.
Example of a problem:
I--I--I--I--I--I--I--I--I--I--I
1 ^ 2
Count the markings like this: 1.1, 1.2, 1.3, 1.4, 1.5 .
the furthest you can go with a decimal until you get a full number is 0.9.
If you are solving a question with full numbers (example: 20 through 30), you would count normally.
I--I--I--I--I--I--I--I--I--I--I
20 ^ 30
The answer would be 25 for this one.
I hope this helps you out in the future.

Astore pays $927.40 for a water heater and marks the price up by 5%. What is the new price?
Answer:
$973.77
Step-by-step explanation:
$927.40 = 100%
New price = 100% + 5%
New price = 105% of 927.40
105% of 927.40 = 1.05(927.40)
1.05(927.40) = 973.77

Bruno and Willie need a total of $50,000 to start an accounting business. Bruno has spent a lot of time getting the business set up, so Willie agrees to contribute $12,000 more than Bruno. How much money will Willie contribute?
The amount contributed by Willie and Bruno is $31000 and $19,000 respectively.
Let amount contributed by Willie be x
Let amount contributed by Bruno be y
Since Willie agreed to contribute $12,000 more than Bruno;
Therefore;
x - y = 12000....…....... equation (1)x + y = 50,000...…....... equation (2)By solving the system of equations simultaneously;
2x = 62000x = 31000and y = 50,000 - 31000y = 19,000In essence; The amount contributed by Willie and Bruno is $31000 and $19,000 respectively.

Which set of ordered pairs does not represent a function?

O{(-6, -9), (-2, -3), (–9,2), (2, -3)}
O {(-2,0), (-5,8), (7,9), (6,8)}
O {(6,9), (-7,8), (1, –4), (8,8)}
O{(-2, -6), (-1,2), (-2, – 7), (6,6)}
Submit Answer
Answer:
Option 4: {(-2, -6), (-1,2), (-2, – 7), (6,6)}
Step-by-step explanation:
Definitions:A function is a relation for which no two ordered pairs have the same first component (or x-values) and different second component (y-values). The set of first components is the input, also referred as the domain. The set of second components is the output, also referred as the range.In order to determine whether a given relation is a function, one must always take notice of the x-values ⇒ make sure that an x-value does not have more than one corresponding y-value.
Solution:Option 1: {(-6, -9), (-2, -3), (–9,2), (2, -3)} ⇒ This relation is a function. Each input has one corresponding output.
Option 2: {(-2,0), (-5,8), (7,9), (6,8)} ⇒ This relation is also a function. Each input has one corresponding output.
Option 3: {(6,9), (-7,8), (1, –4), (8,8)} ⇒ This relation is also a function. Each input has one corresponding output.
Option 4: {(-2, -6), (-1,2), (-2, – 7), (6,6)} ⇒ This relation is not a function. The x-value, x = -2, has two corresponding y-values: y = -6, and y = -7.
Therefore, the correct answer is Option 4: {(-2, -6), (-1,2), (-2, – 7), (6,6)}.
Answer:
