Answer:
c is the answer
Step-by-step explanation:
so we know one equation
y=6x+15
we need to find the other one
24-10=14
14 miles in 2 hours
7 miles in 1 hour
y=7x+10
henry's ballon begins at 10 miles from the town and is 24 miles from the town in 2 hours
Where henry starts is 10 the y-intercept
look at the slopes
Henry: y=7x+10
Tasha: y=6x+15
Tasha starts farther away
Henry goes farther
Answer: Option C is correct.
<h3><u>Part A</u></h3>
⇒ 4x = 20
⇒ x = 20/4
⇒ x = 5
<h3><u>Part B</u></h3>
⇒ x/2 = 8
⇒ x = 8(2)
⇒ x = 16
<h3><u>Part C</u></h3>
⇒ x + 8 = 3x
⇒ 3x - x = 8
⇒ 2x = 8
⇒ x = 4
<h3><u>Part D</u></h3>
⇒ x = (x + 5)/2
⇒ 2x = x + 5
⇒ 2x - x = 5
⇒ x = 5
Answer:
∠ 2 = 70°
Step-by-step explanation:
∠ 13 and ∠ 14 are adjacent angles and sum to 180° , then
12x - 22 + 9x - 29 = 180
21x - 51 = 180 ( add 51 to both sides )
21x = 231 ( divide both sides by 21 )
x = 11
Then
∠ 14 = 9x - 29 = 9(11) - 29 = 99 - 29 = 70°
∠ 7 = ∠ 14 = 70° ( Alternate angles )
∠ 2 = ∠ 7 = 70° ( Alternate angles )
The correct answer according to me is 3=12
Answer:
-a² + 2ab + b² is your answer, or C).
Step-by-step explanation:
b(a + b) -a (a - b)
Distribute b to (a + b), and -a to (a - b)
b(a + b) = ab + b²
-a(a - b) = -a² + ab
Simplify. Combine like terms.
(-a² + ab) + (ab + b²) = -a² + 2ab + b²
-a² + 2ab + b² is your answer, or C).
