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
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
what is the point given in y - 2 = 6(x+5)?
Answer:
-5,2
PLS MARK BRAINLIEST
Step-by-step explanation:
The points are (x1,y1)
using the formula
y-y1 = m(x-x1)
comparing these: - y = -2 ;y = 2
-x1 =5; x1 = -5
(-5,2) the points
m =6 (slope )

James recently hired a plumber to do some necessary work. On the final bill, James was charged a total of $593. $365 was listed for parts and the rest for labor. If the hourly rate for labor was $76, how many hours of labor was needed to complete the job?
(A) First write an equation you can use to answer this question. Use x as your variable and express any percents in decimal form in the equation.
The equation is ______
(B) Solve your equation in part (A) to find the number of labor hours needed to do the job.
Answer: The number of labor hours was _____
Answer:
A. 593 = 365 + 76x
B. 3 hours
Step-by-step explanation:
593 = 365 + 76x
228 = 76x

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.

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

Step-by-step explanation:
★ Solution :-[tex]\sf \longmapsto 139^2 - 138^2[/tex]
[tex]\sf \longmapsto a^2 - b^2 = (a + b)(a - b)[/tex]
Here,
a = 139b = 138[tex]\sf \longmapsto 139^2 - 138^2 = (139 + 138)(139 - 138)[/tex]

Step-by-step explanation:
Algebraic Identity: a²-b²=(a-b)(a+b)
Hence,

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)

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
