. Which graph represents the solution to the inequality below? 4 – 2x > -2
Please help. Will mark as Brainliest.
Answer: Choice A
Arithmetic, common difference = -10
==========================================
Explanation:
We subtract 10 from each term to get the next one
5-10 = -5
-5-10 = -15
-15-10 = -25
This is the same as adding -10 to each term
5+(-10) = -5
-5+(-10) = -15
-15+(-10) = -25
So this is why the common difference is -10 and the sequence is arithmetic.

A group of seven golfers paid $345 to play a round of golf. Of the golfers, one is a member of the club and six are nonmembers. Another group of golfers consists of two members and two
nonmembers. They paid a total of $140. What is the cost for a member to play a round of golf, and what is the cost for a nonmember?
Answer:
member = 15
nonmember = 55
Step-by-step explanation:
m = member, n= nonmember
1m+6n=345
2m + 2n =140 (divide all by 2 )
m + n = 70
m= 70 - n
70-n + 6n =345
70 + 5n = 345
5n = 345-70
5n = 275
n = 275÷5
n = 55
m = 70 - 55 = 15
m=15
Given the function f(x) = −2x2 + 3x + 10, find f(1) and f(3). Choose the statement that is true concerning these two values.
Answer:
The value of f(1) is greater than value of f(3)
Step-by-step explanation:
We substitute..x = 1..into the given equation....where we say...
; -2(1)^2 + 3(1) + 10 = 11
Then we substitute..x = 3..into the given equation
;-2(3)^2 + 3(3) + 10
;-2(9) + 9 + 10 = 1
If f(1) = 11 and f(3) = 1...then the value of f(1) is greater than the value of f(3)
Step-by-step explanation:
The given function is f(x) = -2x² + 3x + 10. We are asked to find f(1) and f(3).To find f(1), we substitute 1 in the place of x in the given function and evaluate it.
That is,f(1) = -2(1)² + 3(1) + 10= -2 + 3 + 10= 11To find f(3), we substitute 3 in the place of x in the given function and evaluate it.
That is,f(3) = -2(3)² + 3(3) + 10= -18 + 9 + 10= 1We see that f(1) is larger than f(3).
Hence, the correct answer is "The value of f(1) is larger than the value of f(3)."

the building and equipment. Make a table of values and then write an equation for C,
in terms of p, representing total cost, in dollars, of producing p phones in a given day.
Write an equation
Answer:150p + 300 = x
Step-by-step explanation: Cost $450
For making a phone a day
150p + 300 = x
The required expression representing the total cost in dollars of producing p phones in a given day is C = 150P + 300.

Step-by-step explanation:
Im not 100% sure this is correct but what I did was
Y=2(x-1)^2+6
2(x-1) = 2x -2
Y=2x -2^2 +6
Y=2x -4 + 6
