1. (MGSE9-12.F.BF.1) This table shows the number of people at a festival at certain times during
the day. Which function best represents the table below?
Hour (PM) 1 2 4 7 8
Number of People 12 19 33 54 61
A. f(x) = 7x + 12
B. f(x) = 7x + 5
C. f(x) = 5x + 7
D. f(x) = 5x + 12
Answers
Answer:
[tex] f(x) = 7x + 5 [/tex].
Step-by-step explanation:
The equation that represents the function can be written in the slope-intercept form, [tex] f(x) = mx + b [/tex].
To create an equation, we need to find the slope (m) and the y-intercept (b) of the function.
First, calculate the slope of the function using two points, (1, 12) and (2, 19).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{19 - 12}{2 - 1} = \frac{7}{1} = 7 [/tex]
Next, find b by substituting x = 1, f(x) = 12, and m = 7 into [tex] f(x) = mx + b [/tex].
[tex] 12 = (7)(1) + b [/tex]
[tex] 12 = 7 + b [/tex]
Subtract 7 from each side
[tex] 12 - 7 = b [/tex]
[tex] 5 = b [/tex]
[tex] b = 5 [/tex]
Substitute m = 7 and b = 5 into [tex] f(x) = mx + b [/tex].
✅Thus, the equation that represents the function would be:
[tex] f(x) = 7x + 5 [/tex].
A line passes through the points(4,10) and (9,20) Write a linear function in terms of X and Y for this line
Answers
Answer:
y = 2x + 2
Step-by-step explanation:
given : line passes through the points (4,10) and (9,20)
Required : write a linear function in terms of x and y
solution :
substitute the coordinate points into the equation: y = mx + b
(x=9, y=20) _ 20 = 9m + b
(x=4, y=10) 10 = 4m + b
subtracting 10 = 5m
m = 10/5
m = 2
substitute x=2 back into eq.1 to solve for b
20 = 9m + b
20 = 9(2) + b
20 - 18 = b
b = 2
therefore the straight line equation is:
y = mx + b
y = 2x + 2
The sum of two numbers is 46. The larger number is two less than three times the smaller number. Find the numbers.♀️
Answers
Answer:
Smaller number: 12
Larger number: 34
Step-by-step explanation:
Let x represent the smaller number.
Let 3x - 2 represent the larger number (The larger number is two less than three times the smaller number, or x)
x + 3x -2 = 46
Add 3x + x:
4x - 2 = 46
Add 2 to both sides:
4x = 46 + 2
Add 46 + 2:
4x = 48
Divide both sides by 4:
4x/4 = 48/4
x = 12 is the smaller number
Since 12 is the smaller number, and the sum of the two numbers is 46, than the larger number must be 34.

Explain at least one way solving an
inequality is different than solving an
equality.
Answers
Answer:
Inequalities are used to demonstrate relationships between numbers or expressions. An inequality describes a relationship between two different values.
The notation
a
<
b
means that
a
is strictly smaller in size than
b
, while the notation
a
>
b
means that
a
is strictly greater than
b
.
The notion
a
≤
b
means that
a
is less than or equal to
b
, while the notation
a
≥
b
means that
a
is greater than or equal to
b
.
Inequalities are particularly useful for solving problems involving minimum or maximum possible values.

A phone company charges a base fee of $12 per month plus an additional charge per minute. The monthly phone cost C can be represented by this equation: C=12+a⋅m, where a is the additional charge per minute, and m is the number of minutes used.
Which equation can be used to find the number of minutes a customer used if we know a and C?
A
m=C−12a
B
m=(C−12)−a
C
m=C−12a
D
m=Ca−12
Answers
Answer:
It’s actually m = (C - 12) /3 But I don’t see it in the 4 option you have.
Step-by-step explanation:
C = 12+ am
C - 12 = am
(C - 12) /a = m
Answer:
beside in this equation where C=$12 a= the additional charges and m= minutes used the equation would be C m=C-12a

Fill in the blank to complete the equation below. 99 + 33 = 11(?+3)
Answers
Answer:
? = 9
Step-by-step explanation:
you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!

Mario deposited $6,500 in a simple interest account that pays 2.8% interest annually. If Mario leaves the money in the account for 12 years, how much interest will he earn?
Answers
Answer:
$2,184
Step-by-step explanation:
Simple interest = (Principal × Rate × Time) / 100
Principal = $6,500
Rate = 2.8%
Time = 12 years
Simple interest = (Principal × Rate × Time) / 100
= (6,500 × 2.8 × 12) / 100
= 218,400 / 100
= 2,184
Simple interest = $2,184
The simple interest on $6,500 at 2.8% for 12 years is $2,184

Answer:
Read left to right
Do parenthesis first
-4 ( 1 + 5) ^2
-4 (6) ^2
Then exponent
6^2 = 6 x 6 = 36
-4 x 36 = -144
Then divide
-144 / 6 = -24
Then the next parenthesis
(42+5) = 47
-24 - 47 = -71
Step-by-step explanation:
Step: -4(1+5)^2/6 -(42+5)
=-4(6^2)/6 -(42+5)
=( -4) (36)/6 -(42+5)
=-144/6 -(42+5)
= -24-(42+5)
= -24-47
= -71
