Find the x- and y-intercept of the line.
-1.2x + 8.2y = 39.36
The x- and y-intercept of the line -1.2x + 8.2y = 39.36 are -32.8 and 4.8
Finding x and y intercepts of a line:An intercept is a point at which the line crosses the axis of a graph. The point at which the line crosses the x-axis is known as the x-intercept, whereas if a line crosses the y-axis at a point, then the point will be the y-intercept.
Here we have,
-1.2x + 8.2y = 39.36
To find x - intercept substitute y = 0
=> -1.2x + 8.2(0) = 39.36
=> -1.2x = 39.36
=> x = 39.36/1.2
=> x = -32.8
To find y - intercept substitute x = 0
=> -1.2(0) + 8.2y = 39.36
=> 8.2y = 39.36
=> y = 39.36/8.2
=> y = 4.8
Therefore
The x- and y-intercept of the line -1.2x + 8.2y = 39.36 are -32.8 and 4.8

________ where f(x) =5-2x^2 increasing?
(-inf,0)
(0,inf)

(-inf,5)
The quadratic function is increasing on the interval:
(-∞, 0)
On which interval is the function increasing?
Here we want to see on which intervals is the quadratic function increasing.
Or function is:
f(x) = 5 - 2x^2
Notice that we have a negative leading coefficient, which means that the parabola opens downwards.
Then the function will be increasing from negative infinity to the x-value of the vertex.
Remember that for the general quadratic:
y = a*x^2 + b*x + c
the x-value of the vertex is:
x = -b/2a
In this case we don't have a linear term, so b = 0, then the vertex is at x = 0.
Which means that the function is increasing on the interval (-∞, 0)

2. Esther trabaja como mesera en el restaurante de su familia. Ella trabaja 2 horas cada mañana durante el turno del

Si Esther trabaja la misma cantidad de horas todas las noches, ¿cuántas horas trabajó durante cada turno de la
noche?
Respuesta:
5
Explicación paso a paso:
28- (2*4)= 20
20/4=5
28 es el total de horas
2 horas por la mañana durante cuatro días
20 es el total de horas por la noche
4 días trabajados
5 es horas cada día durante la noche
Answer:
Durante cada turno de la noche Esther trabajo 5 horas
Step-by-step explanation:
Primero hallemos cuantas horas trabaja Esther en un día
[tex]2 + x = horas\ en \ un\ dia[/tex]
2 es el número de horas que trabaja en cada turno de la mañana y [tex]x[/tex] el número de horas que trabaja en su turno de la noche (en este momento desconocemos el valor de [tex]x[/tex] y es el que queremos hallar). Ahora se tiene que en 4 días ester trabaja 28 horas en total, por lo tanto, multiplicamos 4 a ambos lados de la ecuación para conservar la igualdad
[tex]4\times (2 + x) = horas\ en \ cuatro \ dias[/tex]
[tex]8+4x= 28[/tex]
Ahora se despeja [tex]x[/tex] de la ecuación anterior
[tex]4x=28-8=20\\x=\frac{20}{4} =5[/tex]
De tal manera que Esther en cada turno nocturno trabaja 5 horas

A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week. She noticed that when she reduces the price such that she earns $1 less in profit from each bouquet, she then sells three more bouquets per week. The relationship between her weekly profit, P(x), after x one-dollar decreases is shown in the graph below.
A graph for p of x is a downward open parabola with its vertex at (5, 725) and passes through the points (negative 10, 0), and (20, 0).
Use the graph to complete each statement about this situation.
The maximum profit the florist will earn from selling celebration bouquets is $
.
The florist will break-even after
one-dollar decreases.
The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (
,
).
Answer:
We use the attached graph
a. The maximum profit is the y value that is the value of P(x) that reaches maximum. From the graph the maximum value of P(x) is 675
So the maximum profit the florist will earn from selling bouquets = $675
b. Break even is the point where the profit p(x) becomes 0
From the graph we can see that P(x) =0 at x= -10 and x=20
x=-10 is invalid
So, break even after 20 one- dollar decreases
c. The interval of number of one dollar decreases is where the profit P(x) is greater than 0.
From the graph its very clear that the profit P(x) is greater than 0 in the interval 0 to 20.
So, The interval of number of one dollar decreases for which the florist makes a profit from celebration bouquet is (0, 20)
The cost of the pendant is 3/4 the cost of the bracelet. If their total cost is P413 how much does the pendant cost?
Answer:
P 717
Step-by-step explanation:
Fraction addition using algebra:
Let the cost of bracelet = x
[tex]\sf Cost \ of \ pendent = \dfrac{3}{4}*Cost \ of \ bracelet[/tex]
[tex]\sf = \dfrac{3}{4}x[/tex]
Cost of bracelet + cost of pendent = 413
[tex]\sf x + \dfrac{3}{4}x = 413\\\\ \dfrac{4}{4}x+\dfrac{3}{4}x=413[/tex]
[tex]\sf \dfrac{7}{4}x=413[/tex]
Muliply both sides by 4,
[tex]\sf 4*\dfrac{7}{4}x = 413*4\\\\[/tex]
7x = 413 * 4
Now, divide both sides by 7
[tex]\sf x = \dfrac{413*4}{7}\\\\ x = 59*4\\\\x = 236[/tex]
Cost of bracelet = P 236
Cost of pendent = 413 - 236
= P 177
The speed of a stream is 5 mph. A boat travels 9 miles upstream in the same time it takes to travel 19 miles downstream. What is the speed of the boat in still water?
Answer: 14 mph
Step-by-step explanation:
Let x = the speed of the boat in still water.
Then the speed of the boat relative the bank of the river is u-5 km/hb when it moves upstream, and u+5 when it moves downstream.
We can write the basic equation for travel and distance problems
Time = Distance/Speed in the form
t = 9/x-5 for moving upstream, and
t = 19/x+5 for moving downstream.
Since the left side, t, is the same in both equations, you get a single equation for u
9/x-5 = 19/x+5
To solve it, multiply both sides by the product (x-5)*(x+5) and simplify:
9*(x+5) = 19*(x-5),
9x + 45 = 19x - 95,
45 + 95 = 19x - 9x,
10x = 140,
u = 140/10 = 14 mph.
hope this helps

The first derivative by implicit differentiation of 2 · x⁶ + 5 · x⁴ · y - 7 · x · y⁶ = 8 is y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵).
How to find the derivative of a given function by implicit differentiation
Implicit differentiation is a differentiation method for implicit functions that combines chain rule and derivative rules. First, define the original function:
2 · x⁶ + 5 · x⁴ · y - 7 · x · y⁶ = 8
Second, use chain rule and derivative rules in the expression of the previous step:
12 · x⁵ + 20 · x³ · y + 5 · x⁴ · y' - 7 · y⁶ - 42 · x · y⁵ · y' = 0
Third, clear y' within the resulting equation:
12 · x⁵ + 20 · x³ · y - 7 · y⁶ + (5 · x⁴ - 42 · x · y⁵) · y' = 0
(5 · x⁴ - 42 · x · y⁵) · y' = 7 · y⁶ - 20 · x³ · y - 12 · x⁵
y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵)
The first derivative is y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵).

The correlation coefficient, r, of the data (1 , 6) , (3 , 4) , (5 , 2) is calculated as: r = -1
What is Correlation Coefficient?The correlation coefficient can be described as a numerical value that ranges from -1 through 0, to 1. It is a test of the strength of the relationship between two different variables. It is denoted as "r".
The formula for finding the correlation coefficient (r) between two variables x and y is given as:
