Answer:
B
Step-by-step explanation:
The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
We can plug in the given values to get:
(x - 1)^2 + (y - 2)^2 = 3^2
This is the sam as option B

Given m || n, find the value of x and y.
m(2y+19)
n(5x+28)(4x-11)
Answer:
[tex]m || n \\ (4x - 11) + (5x + 20) = 180 \\ 9x + 9 = 180 \\ 9(x + 1) = 180 \\ x + 1 = 20 \\ x = 19 \\ \\ then \\ (4x - 11) = (2y + 19) \\ (4 \times 19 - 11) = (2y + 19) \\ 65 = 2y + 19 \\ 2y = 46 \\ y = 23[/tex]

you spin the spinner shown below once. each sector shown has an equal area. what is P(ladybug)
Answer:
1/5 or 20%
All sectors have an equal area, so that means that all have an equal chance of being landed on. There is only 1 sector containing a ladybug out of all 5 sectors. That means you have a 1 out of 5 chances of landing on the ladybug if you spin once.

Chris is six years older than his sister Kennedy. The sum of their ages is 38. Write an equation to find Chris and Kennedy's ages. Make certain that you indicate what the variable represents.
Answer:16 , 22
Step-by-step explanation:
Given
Chris is six-year older than his sister
The sum of their ages is 38
Suppose the age of Chris sister is x
So Chris age is [tex]x+6[/tex]
the sum is
[tex]\Rightarrow x+x+6=38\\\Rightarrow 2x+6=38\\\Rightarrow 2x=32\\\Rightarrow x=16[/tex]
Chris age [tex]16+6=22\ \text{years}[/tex]
Chris sister Kennedy's age [tex]16\ \text{years}[/tex]

Answer:
-17 9/26 - > -17.35 , -17.3 with the mark over ,- [tex]\sqrt{300}[/tex] , 172/10
Step-by-step explanation:
Convert all of these into decimals
- [tex]\sqrt{300}[/tex] -> -17.32
-17 9/26 - > -17.35
172/10 -> 17.2
-17.3 with the mark over 3 is ->- 17.3333
Now arrange
-17 9/26 - > -17.35 , -17.3 with the mark over ,- [tex]\sqrt{300}[/tex] , 172/10

why is this true 7a+4-2a=7a+ -2a+4
Answer:
Step-by-step explanation:
Notice that both sides involve 7a - 2a, and both involve 4. By the associative property the order in which the addends appear is immaterial; the left side therefore equals the right side.
Answer:
7a + 4 - 2a = 7a - 2a + 4
5a + 4 = 5a + 4
Step-by-step explanation:
7a + 4 - 2a = 7a - 2a + 4
7a + 4 - 2a
Rearrange the terms.
7a - 2a + 4
Combine like terms.
5a + 4
The left side simplifies to 5a + 4.
7a - 2a + 4
5a + 4
The right side also simplifies to 5a + 4.

(4pq+3q)² - (4pq - 3q)²
Answer:
48pq².
Step-by-step explanation:
(4pq+3q)² - (4pq - 3q)²
This is the difference of 2 squares so we can use the identity
a^2 - b^2 = (a - b)(a + b):
(4pq+3q)² - (4pq - 3q)²
= (4pq + 3q - (4pq - 3q)(4pq + 3q + (4pq - 3q)
= (4pq + 3q - 4pq + 3q)(4pq + 3q + 4pq - 3q)
= 6q * 8pq
= 48pq².
Answer:
48pq²
Step-by-step explanation:
As we know,
(a + b)² = a² + 2ab + b²
and
(a – b)² = a² – 2ab + b²
So,
(4pq+3q)² - (4pq - 3q)²
= [(4pq)² + 2 X 4pq² X 3q + (3q)²] – [(4pq)² - 2 X 4pq² X 3q + (3q)²]
= (16p²q² + 24pq²+ 9q²) – (16p²q² – 24pq²+ 9q²)
= 16p²q²+ 24pq²+ 9q² – 16p²q²+ 24pq² – 9q²
= 24pq² + 24pq²
= 48pq²
Two apples cost 60 cents. How much do five cost?
cost?
Answer:
5 apples cost = 150 /-
Step-by-step explanation:
Two apples cost = 60 /-
Then 1 apple cost = 60 ÷ 2
= 30
∴ 1 apple cost = 30 /-
Then 5 apples cost = 30 × 5
= 150
∴ 5 apples cost = 150 /-

Answer:
The equation for the speed of the train is: 162 = 3x
I think the speed of the train is 54 miles per hour
Step-by-step explanation:
We know that:
y = distance in miles
x = speed of train (miles/hour)
t = time traveled from the departing station (hours)
The equation: y = xt is given, we can therefore substitute the give values:
y = xt or tx
162 = 3x (This would be the equation)
Now we can find x by diving 3 on both sides of "="
162/3 = x
54 = x (This would be the speed of train)

Answer:
y = 5√3
x = 10√3
Step-by-step explanation:
From the given sides
Adjacent = 15
Opposite = y
Hypotenuse = x
Angle of depression = 30degree
Using the SOH CAH TOA identity
tan theta = opp/adj
tan 30 = y/15
y = 15tan30
y = 15(1/√3)
y = 15√3/3
y = 5√3
Similarly
cos theta = adj/hyp
cos 30 = 15/x
x = 15/cos30
x = 15 /√3/2
x = 30/√3
x = 30√3/3
x = 10√3
