Edward has $400 more than Robert. After Edward spends $60 on groceries, he has three times more money than Robert. How much money does Robert have?
Answer: 170
Step-by-step explanation:
We can set up simultaneous equations such that:
E = R+400
E - 60 = 3R
Solving gives R = 170 and E =570
Answer:
Robert has $140
Step-by-step explanation:
400 - 60 = 420
420/3 = 140

ZB (82 +28)º, then find the measure of ZA.
9514 1404 393
Answer:
48°
Step-by-step explanation:
Supplementary angles total 180°.
m∠A +m∠B = 180°
(6x -30)° +(8x +28)° = 180°
14x = 182 . . . . . . . . . . . . . . . . divide by ° and add 2
x = 13 . . . . . . . . . . . . . . . . . . . .divide by 14
Then the measure of angle A is ...
m∠A = (6·13 -30)° = 6(13 -5)° = 6·8°
m∠A = 48°

Step-by-step explanation:
(x + y)2, when x = 6 and y = 9.
Answer in screenshot.
When x = 6 and y = 9, the value of the expression (x + y)² is 225.
Given an expression:
(x + y)²
It is required to find the value of the expression when the value of x = 6 and the value of y = 9.
In order to find the required value of the expression when x = 6 and y = 9, it is required to substitute the value of x and y accordingly to the given expression.
So, substitute x = 6 and y = 9 in the expression (x + y)².
Then the expression becomes:
(x + y)² = (6 + 9)²
= 15²
= 225
Hence the value is 225.

9(p-4)= 6p solve for p
Answer:
p = 12
Step-by-step explanation:
9(p - 4) = 6p
simplify
9p - 36 = 6p
subtract 6p from both sides
3p - 36 = 0
add 36 to both sides
3p = 36
divide both sides by 3
p = 12
9(p-4)= 6p
multiply the bracket by 9
(9)(p)=9p
(9)(-4)=-36
9p-36=6p
move +9p to the other side to combine like terms
sign changes from +9p to -9p
9p-9p-36=6p-9p
-36=6p-9p
-36=-3p
divide both sides by -3 to get p by itself
-36/-3=-3p/3
12=p
answer:
p=12

The general form of a hyperbola is 9x2−5y2−54x−10y+31=0.
What is the standard form of this hyperbola?
Answer:
The standard form of this hyperbola is [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex].
Step-by-step explanation:
From Analytical Geometry, the standard form of the hyperbola is defined by the following expression:
[tex]\frac{(x-h)^{2}}{a^{2}}-\frac{(y-k)^{2}}{b^{2}} = 1[/tex] (1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]a, b[/tex] - Semiaxis lengths, dimensionless.
[tex]h, k[/tex] - Coordinates of the center, dimensionless.
Let the hyperbola be defined by [tex]9\cdot x^{2}-5\cdot y^{2}-54\cdot x -10\cdot y +31=0[/tex], we proceed to derive the standard form by algebraic means:
1) [tex]9\cdot x^{2}-5\cdot y^{2}-54\cdot x -10\cdot y +31=0[/tex] Given
2) [tex](9\cdot x^{2}-54\cdot x)+(-1) \cdot (5\cdot y^{2}+10\cdot y)+31 = 0[/tex] Commutative and associative properties/[tex](-1)\cdot a = -a[/tex]
3) [tex](9\cdot x^{2}-54\cdot x + 81)+(-81)+(-1)\cdot (5\cdot y^{2}+10\cdot y +5)+(-1)\cdot (-5)+31 = 0[/tex] Modulative, distributive and associative properties/[tex](-1)\cdot a = -a[/tex]/Existence of the additive inverse
4) [tex](3\cdot x-9)^{2}+(-1)\cdot (\sqrt{5}\cdot y +\sqrt{5})^{2}+(-81)+5+31 = 0[/tex] Perfect trinomial square/[tex](-a)\cdot (-b) = a\cdot b[/tex]/Commutative property
5) [tex]9\cdot (x-3)^{2}+(-1)\cdot (5) \cdot (y+1)^{2}-45 = 0[/tex] Distributive property/[tex](a\cdot b)^{c} = a^{c}\cdot b^{c}[/tex]/Definition of addition and subtraction.
6) [tex]9\cdot (x-3)^{2}-5\cdot (y+1)^{2}= 45[/tex] [tex](-1)\cdot a = -a[/tex]/Compatibility with addition/Existence of additive inverse/Modulative property.
7) [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex] Compatibility with multiplication/Definition of division/Distributive property/Result.
The standard form of this hyperbola is [tex]\frac{(x-3)^{2}}{5}-\frac{(y+1)^{2}}{9} = 1[/tex].
