If a+b=13, and ab-40, then find a3+b3
Answer:
[tex]637[/tex]
Step-by-step explanation:
Step 1: Set Up System of Equations
[tex]a + b = 13[/tex]
[tex]ab = 40[/tex]
Solve for a in the first equation
[tex]a = 13 - b[/tex]
Subsitur that in for the 2nd equation
[tex](1 3 - b)(b) = 40[/tex]
[tex] - b {}^{2} + 13b = 40[/tex]
[tex] - {b}^{2} + 13b - 40[/tex]
[tex] - (b - 5)(b - 8)[/tex]
Set each monomial to zero
Think of a number that adds to 13 and multiply to 40.
Th
[tex]b = 5[/tex]
[tex]b = 8[/tex]
So the answer is 5 and 8. Remember factos are interchangeable so a and b can be either 8 or 5.
Cubed both 5 and 8.

Answer:
d = 6
Step-by-step explanation:
Since the line is horizontal then the distance from B to C is the distance between the x- coordinates.
d = | - 3 - 3 | = | - 6 | = | 6 | = 6
Answer:
option C
Step-by-step explanation:
[tex]distance, d = \sqrt{(x_B- x_C)^2 + (y_B - y_C)^2}[/tex]
[tex]=\sqrt{(-3 -3)^2 + (6 - 6)^2 }\\\\=\sqrt{(-6)^2 + 0 }\\\\=\sqrt{36}\\\\= 6[/tex]
The difference between 32.6 and a number is 10.2. Which equation can be used to solve this problem?
32.6 minus y = 10.2
y minus 36.2 = 10.2
10.2 minus y = 32.6
y + 32.6 = 10.2
Answer:
The answer is 10.2-y=32.6 D. y+32.6=10.2
Step-by-step explanation:
Given : The difference between 32.6 and a number is 10.2
Let the number be : y
⇒ 32.6 - y = 10.2
⇒ 32.6 minus y = 10.2

A triangle has side lengths of (5.5x + 6.2y) cm, (4.3x + 8.3z) cm, and (1.6z - 5.1y) cm. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
9.8x+1.1y+9.9z
Step-by-step explanation:
Hi there!
Perimeter = Sum of all sides
[tex]P=(5.5x + 6.2y)+(4.3x + 8.3z)+(1.6z - 5.1y)[/tex]
Open up the parentheses
[tex]P=5.5x+6.2y+4.3x+8.3z+1.6z-5.1y[/tex]
Combine like terms
[tex]P=5.5x+4.3x+6.2y-5.1y+8.3z+1.6z\\P=9.8x+1.1y+9.9z[/tex]
Therefore, the expression 9.8x+1.1y+9.9z (cm) best represents the perimeter of the triangle.

Step-by-step explanation:
The Chang family is on their way home from a cross-country road trip. During the trip, the function D(t)=3260−55t can be used to model their distance, in miles, from home after t hours of driving. find D(12) and interpret the meaning in the context of the problem.
Answer:
D(12) = 2,600 miles
It means a distance of 2,600 miles is already traveled from home after 12 hours
Step-by-step explanation:
To find D(12); all we have to do is to substitute the value of 12 for D
We have this as;
D(12) = 3260-55(12)
D(12) = 2,600
In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours

Answer:
[tex]z = 6[/tex]
Step-by-step explanation:
Let's solve:
[tex]5(z+1)=3(z+2)+11[/tex]
Step 1: Simplify both sides of the equation.
[tex]5(z+1)=3(z+2)+11 \\ (5)(z)+(5)(1)=(3)(z)+(3)(2)+11(Distribute) \\
5z+5=3z+6+11 \\
5z+5=(3z)+(6+11)(Combine Like Terms) \\
5z+5=3z+17 \\
5z+5=3z+17[/tex]
Step 2: Subtract 3z from both sides.
[tex]5z+5−3z=3z+17−3z \\ 2z+5=17[/tex]
Step 3: Subtract 5 from both sides.
[tex]2z+5−5=17−5 \\ 2z=12[/tex]
Step 4: Divide both sides by 2.
[tex] \frac{2z}{2} = \frac{12}{2} \\ z = 6[/tex]

Answer:
Expression B: 0.8p
Expression D: p - 0.2p
Step-by-step explanation:
The regular price of an item at a store is p dollars. The item is on sale for 20% off the regular price. Some of the expressions shown below represent the sale price, in dollars, of the item.
Expression A: 0.2p
Expression B: 0.8p
Expression C:1 - 0.2p
Expression D: p - 0.2p
Expression E: p - 0.8p
Which two expressions each represent the sale price of the item?
Regular price of the item = $p
Sale price = 20% off regular price
Sale price = $p - 20% of p
= p - 20/100 * p
= p - 0.2 * p
= p - 0.2p
= p(1 - 0.2)
= p(0.8)
= 0.8p
The sale price is represented by the following expressions
Expression B: 0.8p
Expression D: p - 0.2p

Answer:
Step-by-step explanation:
sams house=6 miles east and 9 mies south
let the distance towards east be a and distance towards south be b
so we have to find straight line distance from sams house to amys house .let it be c(or hypotenuse)
according to the pythagors theorem
a^2 + b^2 =c^2
6^2 + 9^2 =c^2
36 + 91 =c^2
117 =c^2
[tex]\sqrt{117[/tex] =c
10.8=c
the two coordinate points are
(4,12)=(x1 , y1)
(6,2)=(x2 , y2)
distance formula = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]
=[tex]\sqrt{(6-4)^2 + (2-12)^2}[/tex]
=[tex]\sqrt{2^2 + (-10)^2}[/tex]
=[tex]\sqrt{4 + 100}[/tex]
=[tex]\sqrt{104}[/tex]
=2[tex]\sqrt{26}[/tex]
=10.1 units
fairy travels=10.1 * 2
=20.2 miles
three sides are 17,8,15
according to the pythagoras theorem
to be right angles triangle square of hypotenuse(longest side) must equal to the sum of square of two other smaller sides
so here 17 is longest and 8 and 15 are two other smaller sides of a triangle
17^2=8^2 + 15^2
289=64 + 225
289=289
since both sides are equal it can be concluded that they form a right angled triangle.

Answer:
1. option b : 10.8 miles
2. Distance = 10.2 units

b)
Grid (units) Distance( miles)
1 2
10.2 x
[tex]\frac{1}{10.2} = \frac{2}{x}\\\\x = 2 \times 10.2\\x = 20.4 \ miles[/tex]
3.
a)
Square of Longer side = sum of squares of other sides
[tex]17^2 = 8 ^2 + 15^2 \\289 = 64 + 225\\289 = 289 \\[/tex]
Yes, Paulie is Correct.
b)
Paulie is correct because the measurements of the sides of triangle satisfies Pythagoras theorem.
Pythagoras' theorem states that for all right-angled triangles, the square on the hypotenuse is equal to the sum of the squares on the other two sides.
