Answer:
k=-3
Explanation:
Plug in x and y values
-40=k(14)+2
-2 both sidea
-42=k(14)
divide by 14 both sides
k=-3
k = -3
Step-by-step explanation:
y = kx + 2 through the point a(14, -40)
Subtitute…
y = kx + 2
-40 = k(14) + 2
-40 = 14k + 2
-40 - 2 = 14k
-42 = 14k
(-42)/14 = k
-3 = k

The value of 2√5 x 5√5 is 50.
What is Radical?The √ symbol that is used to denote square root or nth roots. Radical Expression - A radical expression is an expression containing a square root.
An expression that uses a root, such as a square root, cube root is known as a radical notation.
Given:
2√5 x 5√5
So, Multiplying the roots
= 2√5 x 5√5
= ( 2x 5) ( √5 x √5)
= 10 x 5
= 50
hence, the multiplication of Radical gives 50.

A. V(t)=0.87(22,000)^t
B. V(t)=1.13(22,000)^t
C. V(t)=22,000(0.87)^t
D. V(t)=22,000(1.13)^t
Answer:
C.
Step-by-step explanation:
A and B you can already eliminate because you need to power the rate not the starting value. D is wrong because it's increasing, so if the value increased by 0.13 each year it would be right. So you're left with C

Answer:
A = 8
Step-by-step explanation:
For the equation to have infinitely many solutions , then the terms on both sides must be the same.
Qw require the x- terms on the right side to be 6x
Ax - 2x = 6x ( consider the coefficients )
A - 2 = 6 ( add 2 to both sides )
A = 8
10. Tell whether the sequence is arithmetic. If it is, what is the common difference?
2,7,13,20,...
no
yes: 2
yes; 6
yes; 5
Answer:
not arithmetic
Step-by-step explanation:
An arithmetic sequence has a common difference between consecutive terms.
7 - 2 = 5
13 - 7 = 6
20 - 13 = 7
The difference between consecutive terms is not equal , then
The sequence is not arithmetic

Find two consecutive positive even integers such that the square of the first decreased by 64 equals 3 times the second.
Answer:
10 and 12
Step-by-step explanation:
let the consecutive even integers be n and n + 2 , then
n² - 64 = 3(n + 2) ← distribute parenthesis
n² - 64 = 3n + 6 ( subtract 3n + 6 from both sides )
n² - 3n - 70 = 0 ← in standard form
(n - 10)(n + 7) = 0 ← in factored form
Equate each factor to zero and solve for n
n - 10 = 0 ⇒ n = 10
n + 7 = 0 ⇒ n = - 7
Since n must be a positive even integer then n = 10 and n + 2 = 10 + 2 = 12
The 2 numbers are 10 and 12

Answer:
A) 83 km/ hour
B) 2/7 penalties / game
C) $16 / CD
D) 9 donuts / box
Step-by-step explanation:
A)
For this question they are asking for the distance traveled in 1 hour.
Since 747km was travelled in 9 hours, we divide 747 by 9 to find the distance travelled in 1 hour
747 ÷ 9 = 83
The unit rate is 83 km/ hour
B)
You have to find the number of penalties per game
Like before divide 10 by 35:
10 ÷ 35 = 10/35 = 2/7
2/7 penalties / game
C)
