Answer:
[tex] \frac{105}{6} [/tex]
Step-by-step explanation:
[tex] \frac{21}{2} + \frac{21}{3} [/tex]
lowest common multiple of 2 and 3 is 6
21×3 = 63
21×2= 42
they are now going to have the same denominator of 6
[tex] \frac{63}{6} + \frac{42}{6} [/tex]
now u are just gonna add the neumerators and keep the denominator
[tex] \frac{105}{6} [/tex]
(x - 5)2 + (y-(-3))2 = 34 (x - 5)2 + ( + 3)2 = 34 Exercises 12.2 Complete the following: 1. Find the equation of the circle having the given center and ra (a) C(0,0), r= 3 (c) C(4, 3), r = 5 (d) C(2, (b) C(-2.
Answer:
Step-by-step explanation:
The general equation of the circle
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Center = c = (h,k) , radius = r
if C = (0,0) , r = 3
The equation will be :
(x-0)^2+(y-0)^2=3^2
[tex]x^2+y^2=9[/tex]

y ≤ 7
y ≥ 7
y ≥ –7
y ≤ −7
9514 1404 393
Answer:
(d) y ≤ -7
Step-by-step explanation:
The solution is found by dividing by the coefficient of y. Since that is a negative number, the sense of the comparison is reversed.
-8y ≥ 56
(-8y)/(-8) ≤ 56/(-8)
y ≤ -7

-8 - x = x - 4x
Answer:
−8−x=x−4x
Step 1: Simplify both sides of the equation.
−8−x=x−4x
−8+−x=x+−4x
−x−8=(x+−4x)(Combine Like Terms)
−x−8=−3x
−x−8=−3x
Step 2: Add 3x to both sides.
−x−8+3x=−3x+3x
2x−8=0
Step 3: Add 8 to both sides.
2x−8+8=0+8
2x=8
Step 4: Divide both sides by 2.

Here is a pattern of squares:
Step 1
Step 2
Step 3
Write an equation to represent the relationship between the step number and the
number of squares in the pattern.
Briefly describe how each part of the equation relates to the pattern.
9514 1404 393
Answer:
y = n^2 +nupper left corresponds to n^2; lower right corresponds to nStep-by-step explanation:
The number of squares in the upper left portion of the figure is the number in a square n on a side, so is n^2. The number of squares in the lower right portion of the figure is equal to the step number, n. A suitable equation adds these numbers together.
y = n^2 +n . . . . where y is the number of squares in the pattern of Step n.
Answer:Your answer is...
Step-by-step explanation:
y = n^2 +n

1.Encuentra de dos formas diferentes el área de las figuras mostradas en cada literal:
Answer:
Cuadrilátero A: [tex]A = y^{2}+4\cdot y +4[/tex]
Cuadrilátero B: [tex]A = a^{2}+6\cdot a + 9[/tex]
Step-by-step explanation:
Existen dos formas distintas de determinar las áreas de cada cuadrilátero:
(i) Obtener el área de cada cuadrado y sumar los resultados.
(ii) Calcular los lados del cuadrilátero grande y determinar el área.
Cuadrilátero A
Método (i)
[tex]A = y^{2}+2\cdot y +4+2\cdot y[/tex]
[tex]A = y^{2}+4\cdot y +4[/tex]
Método (ii)
[tex]A = (y+2)\cdot (y+2)[/tex]
[tex]A = y^{2}+4\cdot y + 4[/tex]
Cuadrilátero B
Método (i)
[tex]A = a^{2}+3\cdot a +9 + 3\cdot a[/tex]
[tex]A = a^{2}+6\cdot a +9[/tex]
Método (ii)
[tex]A = (a+3)\cdot (a+3)[/tex]
[tex]A = a^{2}+6\cdot a + 9[/tex]
Amy is x years old. Jennifer is 5 years older than Amy. Their father is 4 times as old as Jennifer. Write an expression to represent the fathers age. Then write an expression to represent the sum of their ages. Make sure your final expresson is simplifed.
Answer:
Refer to explanation below^
Step-by-step explanation:
Amy = x
Jennifer = x + 5
Father = x + 5 x 4 = 4x + 5
Total = 4x + 5 + x + 5 + x = 6x + 10

What is 49% in a decimal
Answer:
0.49
Step-by-step explanation:
Answer:
Step-by-step explanation:
49% = 0.49 in decimal form. Percent means 'per 100'. So, 49% means 49 per 100 or simply 49/100. If you divide 49 by 100, you'll get 0.49 (a decimal number).

find product of 5/12×6
Answer:
2 and 1/2
Result in decimals: 2.5
Step-by-step explanation:
5/12 × 6/1 = 5/2 = 2 and 1/2
Result in decimals: 2.5
Calculation steps:
5/12 × 6/1 = (5 × 6)/(12 × 1) = 30/12
30 ÷ 6 = 5
12 ÷ 6 = 2
= 5/2
= 2 and 1/2
Which of the following is not a function
{(-1,-2), (0, -3),(1,-2), (2,1)}
{(-1,-2), (0, -3), (1, -2), (2, 1)
{(-2, 2), (-1,1),(0,0),(1,1)}
{(-2,0), (2,2), (2, -2), (7,3)}
Answer:
The final set is not a function.
Step-by-step explanation:
There are two x-values that are the same, making it not a function. Notice, this is not the same in the other sets, because each x corresponds to exactly one y-value in the other functions.

Every year, Jada's scout troop makes and sells tie-dyed shirts to raise money for charity. Short-sleeved shirts are easier to make, so they try to sell more short-sleeved shirts than long-sleeved shirts. Last year, her troop sold 20 short-sleeved shirts and 25 long-sleeved shirts. This year, her troop sold 35 short-sleeved shirts and 50 long-sleeved shirts. Which year's sales had a greater ratio of short-sleeved shirts to long-sleeved shirts?
Answer:
long-sleeved
Step-by-step explanation:
long-sleeved shirt has gained 25 more sales than last year while short sleeved shirt sales only gained 15 more sales than last year.

Express the terms of the following sequence by giving an explicit formula.
9, 12 15, 18, 21
A. u(n) = n + 3, where n = 1, 2, 3, 4, . . .
B. u(n) = 6 + 3n, where n = 1, 2, 3, 4, . . .
C. u(n) = 3 + n, where n = 1, 2, 3, 4 . . .
D. u(n) = 3n, where n = 1, 2, 3, 4, . . .
Answer:
B.
Step-by-step explanation:
The common difference is + 3 so we have an arithmetic sequence.
u(n) = a1 + d(n - 1)
= 9 + 3(n - 1)
= 9 + 3n - 3
= 6 + 3n.

NEED HELP WITH GEOMETRY
Answer:
Please look down below
Step-by-step explanation:
∠1 + 69 + 47 = 180 (because straight line)
∠1 = 180 - 116
∠1 = 64
∠2 + ∠1 + 63 = 180 (because triangle)
∠2 + 64 + 63 = 180
∠2 = 180 - 127
∠2 = 53
∠3 + ∠1 = 180 (because straight line)
∠3 + 64 = 180
∠3 = 116
∠5 = ∠4 (given)
∠5 + ∠4 + ∠3 = 180
Denote ∠5 and ∠4 as x, so 2x
2x + ∠3 = 180
2x + 116 = 180
2x = 64
x = 32
∠5 = 32, ∠4 = 32
∠6 + 136 = 180 (because straight line)
∠6 = 44
∠7 + ∠6 + 47 = 180 (because triangle)
∠7 + 44 + 47 = 180
∠7 = 180 - 91
∠7 = 89

At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
A tree diagram. Random student studies for test is 0.6, and does not study for test is 0.4. Studies for test to Gets B or higher is 0.55; does not get B or higher is 0.45. Does not study for test to Gets B or higher is 0.20; does not get B or higher is 0.80.
The professor informs the class that there will be a test next week. What is the probability that a randomly selected student passes the test with a B or higher?
