Solve the following system of inequalities graphically on the set of axes below. State
the coordinates of a point in the solution set.
y > -2x - 1
y > x + 2
Answer:
[tex](x,y) = (-1,1)[/tex]
Step-by-step explanation:
Given
[tex]y>-2x - 1[/tex]
[tex]y>x + 2[/tex]
Required
Solve graphically
See attachment for graph;
The black shade represents [tex]y>-2x - 1[/tex]
While the green, represents [tex]y>x + 2[/tex]
Next, determine the intersection points between the two lines
From the attached graph, we have:
[tex](x,y) = (-1,1)[/tex]
Hence, the solution is:[tex](-1,1)[/tex]

Use △GHJ, where A, B, and C are midpoints of the sides. When AC = 3y−5 and HJ = 4y+2, what is HB?
Use △GHJ, where A, B, and C are midpoints of the sides
HB=14
Given :
Use △GHJ, where A, B, and C are midpoints of the sides
AC = 3y−5 and HJ = 4y+2
Apply mid point theorem
mid segment = half of base
[tex]AC=\frac{1}{2}(HJ)[/tex]
Now we replace AC and HJ
[tex]AC=\frac{1}{2}(HJ)\\3y-5=\frac{1}{2} (4y+2)\\3y-5=2y+1\\Subtract \; 2y\\1y-5=1\\Add \; 5\\1y=1+5\\y=6[/tex]
B is the midpoint . HB is half of HJ
[tex]HB=\frac{1}{2} HJ\\HB=\frac{1}{2}(4y+2)\\x=6\\HB=\frac{1}{2}(4(6)+2)\\\\HB=\frac{1}{2}(28)\\\\HB=14[/tex]
So the value of HB = 14

Jeremy will roll a number cube, numbered 1–6, twice. What is the probability of rolling an odd number, then a number bigger than 2?
Answer:
1/12
Step-by-step explanation:
The probability of rolling an odd number = 3/6
The probability of rolling 2 after an odd number =
1/6
3/6 x 1/6 = 3/36
3/36 = 1/12 (after simplified)
Find all complex solutions of the equation z⁴-1-i=0.
Answer:
Step-by-step explanation:
hello :
z⁴=1+i given : z² = t t is the complex number so : z⁴= (z²)² =t²
solve for t this equation : t² = 1+i
if : t = x+iy t² =(x+iy)² = x²+2xiy+(iy)² =x²-y²+2xyi ...... ( i² = -1)
t² = 1+i means : x²-y²+2xyi = 1+i
you have this system : x²-y² = 1.....(*)
2xy = 1.....(**)
slve for x and y you ca add this equation : ....(***)
( use : t² = 1+i
/t²/ = /1+i/ so :/t/² = /1+i/ .... (√(x²+y²))²=√(1²+1²) =√2 means x²+y² = √2)
the system is : x²-y² = 1.....(*)
2xy = 1.....(**)
x²+y² = √2 ....(***)
add (*) and (***) : 2x²= 1+√2
x² = (√2+1)/2
substrac (*) and (***) you have : y² = (√2-1)/2
use (**) the proudect xy is positif (same sign) so :
x=√( (√2+1)/2) and y = √( (√2-1)/2) so : t1 =√( (√2+1)/2)+i√( (√2-1)/2)
x= -√( (√2+1)/2) and y = -√( (√2-1)/2) so :t2= -t1
same method for equation : z² =t1 ..(2 solution ) and z² = t2..(2 solution )

The local theater has three types of seats for Broadway plays: main floor, balcony, and mezzanine. Main floor tickets are $48, balcony tickets are $45, and mezzanine tickets are $34. One particular night, sales totaled $65,140. There were 381 more main floor tickets sold than balcony and mezzanine tickets combined. The number of balcony tickets sold is 328 more than 2 times the number of mezzanine tickets sold. How many of each type of ticket were sold?
I already have these equations: 48x+45y+34z=65140, x=y+z+381, y=2x+328, but I can't figure out how to substitute them.
Answer: In this problem, you have three unknowns: broadway tickets for the (1) main floor, (2) balcony and (3) mezzanine. To solve algebraic equations, the total number of unknowns must be the same with the number of independent equations. With that, let's formulate these three equations.
Let the 3 unknowns be
x = number of tickets for the main floor
y = number of tickets for the balcony
z = number of tickets for the mezzanine
The independent equations are:
59x+50y+40z=73,785 --> eq 1
x = y+z+435 --> eq 2
y = 78 + 33 z ---> eq 3
Solve the equations simultaneously. Substitute eq3 to eq 2
x = 78+33z+z+435
x = 513+34z --> eq 4
Substitute eq 4 and eq 3 to eq 1
59(513+34z)+50( 78 + 33 z)+40z=73,785
Solve for z using the calculator: z = 11
Use eq 4 to find x: x = 877
Use eq 2 to find y: y = 432
There were 877 main floor tickets, 432 balcony tickets and 11 mezzanine tickets sold.
Step-by-step explanation:
Answer:
Main floor - 892, balcony - 450, mezzanine- 61Step-by-step explanation:
Main floor - x, balcony - y, mezzanine- zEquations:
48x + 45y + 34z = 65140 ↔ (1)x = 381 + y + z ↔ (2)y = 2z + 328 ↔ (3)Substitute (3) into (2):
x = 381 + 2z + 328 + z ⇒ x = 3z + 709 ↔ (4)Substitute (2) and (4) into (1) and solve for z:
48(3z + 709) + 45(2z + 328) + 34z = 65140144z + 48*709 + 90z + 45*328 + 34z = 65140268z + 34032 + 14760 = 65140268z = 65140 - 48792268z = 16348z = 16348/268z = 61Find x and y:
x = 3z + 709 = 3*61 + 709 = 892y = 2z + 328 = 2*61 + 328 = 450What is the area of the figure show

1551
A 315 f12
B 225 fra
C 180 ft2
D 90 fre?
Answer:
315 ft²
Step-by-step explanation:
•Split the shape into a triangle and a square.
•A=bh so 15*15=225 (area of square)
•Since the height of the square is 15, subtract given height of 3 from 15 which is 12 and that is the base of triangle.
• To find the height, subtract 15 since the base is equal to the top side.
•A=1/2bh for triangles so 1/2(15)(12) is 90.
•Add 225 and 90 then boom. 315ft²

Question 4 options:
A)
8
B)
–8
C)
9
D)
–9
Answer:
x = -9
Step-by-step explanation:
Given:
BC = x + 19
ST = x + 29
Required:
Value of x
Solution:
Midsegment theorem states that the midsegment of a triangle = ½ of the length of its third side
Thus:
BC = ½(ST)
Substitute
x + 19 = ½(x + 29)
Multiply both sides by 2
2(x + 19) = x + 29
2x + 38 = x + 29
Collect like terms
2x - x = -38 + 29
x = -9

y^4-2y^2+1...........
Answer:
(y²-1)²
Step-by-step explanation:
Given:
y⁴ - 2y² + 1
Find:
Factor of given equation
Computation:
y⁴ - 2y² + 1
Change given equation in quadratic equation.
(y²)² - 2(y)²(1) + (-1)²
We know that
(a)² - 2(a)(b) + (b)²
(a-b)²
So,
(y²)² - 2(y)²(1) + (-1)²
(y²-1)²

The volume of the polyhedron is ______ cm3.
Answer:
Volume = 144 cm³
Step-by-step explanation:
Volume of the polyhedron = volume of triangular prism = ½*b*h*l
Where,
b = 4 cm
h = 6 cm
l = 12 cm
Substitute
Volume = ½*4*6*12
Volume = 144 cm³
