Answer:
The answer is -72/5.... also as 14.4
Answer:
Step-by-step explanation: first put in the value for x, 8(-6) -5y=24
Then solve from there, 8x-6= -48
-48-5y=24
-5y=24+48 ( becomes pos when transferred to this side, since it turns to the opposite direction )
Now, -5y=72
Decide both sides by -5 and then
Y = -14.4 or -14 2/5

y=x+ - 4x3
Find the two stationary points
on the graph of y=x4 - 4x3
Answers
Answer: [tex](0,0), (3,-27)[/tex]
Step-by-step explanation:
Given
Curve is [tex]y=x^4-4x^3[/tex]
The stationary point on a differentiable function is the points where the differentiation of the function is zero i.e. slope is zero at that point.
Differentiate the curve [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f'(x)=4x^3-12x^2[/tex]
Equate it to zero
[tex]\Rightarrow 4x^3-12x^2=0\\\Rightarrow 4x^2(x-3)=0\\\Rightarrow x=0,0,3[/tex]
Put [tex]x=0,3[/tex] in the function [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f(0)=0\\\Rightarrow f(3)=3^4-4(3)^3\\\Rightarrow f(3)=81-108\\\Rightarrow f(3)=-27[/tex]
Therefore, the stationary points are [tex](0,0), (3,-27)[/tex]

in figure 5.19 to the right PQRS is a rectangle. if PS=5cm and PR=13cm find SR and QS.
Answers
Given:
PQRS is a rectangle.
[tex]PS=5\ cm,\ PR=13\ cm[/tex]
To find:
The length of SR and QS.
Solution:
We know that, all interior angles of a rectangle are right angle. So, [tex]\angle S=90^\circ[/tex].
According to the Pythagoras theorem, in a right angle triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Using Pythagoras theorem in triangle PRS, we get
[tex]PR^2=PS^2+SR^2[/tex]
[tex]13^2=5^2+SR^2[/tex]
[tex]169-25=SR^2[/tex]
[tex]144=SR^2[/tex]
Taking square root on both sides.
[tex]\sqrt{144}=SR[/tex]
[tex]12=SR[/tex]
So, the measure of SR is 12 cm.
We know that the diagonals of a rectangle are equal. PR and QS are the diagonals of the rectangle PQRS. So,
[tex]PR=QS[/tex]
[tex]13=QS[/tex]
Therefore, the length of SR is 12 cm and the length of QS is 13 cm.

David compro 23 boligrafos y 15 lapizes, cada boligrafo le costo 14 pesos y cada lapiz 9. ¿Cuanto gasto en total David?
Answers
Answer:
457 pesos
Step-by-step explanation:
From the above question, we are told that:
David bought 23 pens and 15 pencils.
Each pen = 14 pesos
Each pencil = 9 pesos
The amount of money David spent in total =
(23 × 14 pesos) + (15 × 9 pesos)
= 322 pesos + 135 pesos
= 457 pesos
Therefore, David spent in total 457 pesos

Jamya is making a rectangular blanket. The length of the blanket is 10inches greater than it's worth, W, in inches. Write the function, f(w), that describes the area, in square inches, of Jamya's blanket as a function of the width, w.
Answers
Answer: (w² + 10)inches²
Step-by-step explanation:
Since the width of the rectangular blanket is given as w and the length of the blanket is 10inches greater than it's width, therefore the length will be:
= 10 + w.
Therefore,
length = 10 + w
width = w
Area = length × width
Area = (10 + w) × w
Area = 10w + w²
Therefore, the area of the blanket will be (w² + 10)inches².

Yasmine's Mom had to buy 9 pints of ice cream and each pint cost $2.73 (tax is included in that cost). How much did the 9 pints of ice cream cost? If she paid for the ice cream with $40, how much money did she get back?
Answers
Answer:
$24.57
$15.43
Step-by-step explanation:
Cost per pint of ice cream = $2.73
Number of pints purchased = 9
Total cost = cost per pint * Number of pints
Total cost = $2.73 * 9 = $24.57
If she paid $40
Change collected = $40 - $24.57 = $15.43
