Answer:
Yo Rick Astley
Step-by-step explanation:
y ∝ 1 √ x
y = k (1 √ x)
y = 7 when x = 36
7 = k ( 1 / √36)
7 = k (1/6)
k= 7 × 6
k = 42
If x = 4 then,
y = 42 ( 1/√4)
y = 42 ( 1/2)
y= 21

Consider the linear function f(x) = 3x-1. Find f(0), f(1), f(2)
Answer:
f(0) = -1, f(1) = 2, f(2) = 5.
Step-by-step explanation:
f(0) = 3(0) - 1 = -1
f(1) = 3(1) - 1 = 2
f(2) = 3(2) - 1 = 5
The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = 3x + 1
The value of the function at x = 0 will be
f(0) = 3(0) + 1
f(0) = 0 + 1
f(0) = 1
The value of the function at x = 1 will be
f(1) = 3(1) + 1
f(1) = 3 + 1
f(1) = 4
The value of the function at x = 2 will be
f(2) = 3(2) + 1
f(2) = 6 + 1
f(2) = 7
The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

plssss help me i cant do this stuff
Answer: See explanation: 10, 1, 1, -7
Step-by-step explanation:
I'll assume you are working with Excel. The Product function multiplies all the cells given in the specified range. Here, those are cells A2 through A5. As presnted, this would be [10*5*0*(-7)] = 0, which is the value of cell B2. If we want cell B2 to be -70, we must change one or more of the numbers in cells A2 to A5.
Initial: 10, 5, 0, -7 B2=0
Change: 10, 1, 1, -7 B2 = -70
Other combinations are possible.

The state fair is a popular field trip destination. This year the senior class at High School A and
the senior class at High School B both planned trips there. The senior class at High School A
rented and filled 1 van and 3 buses with 80 students. High School B rented and filled 14 vans
and 1 bus with 218 students. Each van and each bus carried the same number of students. Find
the number of students in each van and in each bus.
Answer:
each bus carries 22 students
each van carries 14 students
Step-by-step explanation:
1v+3b=80
14v+b=218
eliminate b by multiplying the bottom equation by 3.
(42v+3b=654)-(1v+3b=80)=
41v=574
divide both sides by 41
v=14 (each van carries 14 students)
substitute the value of v into either of the og equations
1(14)-14+3b=80-14
3b=66
divide both sides by 3
b=22 (each bus carries 22 students)

If 2k - 3 = 9 (k+7)-3 then k is ????
Answer:
k= -9
Step-by-step explanation:
2k-3=9k+63-3 [expand the 9(k+7) first]
2k-9k=63-3+3 [put the like terms together]
-7k=63 [do the simple math]
k= 63 ÷ by -7
k=-9
Answer:
K = -9
Step-by-step explanation:
2k-3 = 9(k+7)-3
2k-3 = 9k+63-3
2k-3 = 9k+60
2k-9k = 60+3
-7k = 63
-k = 9
k = -9

Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double time rate. Her gross pay was $734.40. What was her hourly rate?
Answer:
15.30 per hour
Step-by-step explanation:
The hourly rate for Mr Frasier will be $15.30.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double-time rate. Her gross pay was $734.40.
The hourly rate will be calculated as:-
Rate = 40 + 2 x 4 = 734.40
Rate = 40 + 8 = 734.40
Rate = 734.40 / 48
Rate = $15.3
The hourly rate is $15.3.

Solve and graph x - 2 > -5 and x - 2 < 4 on a number line
Answer:
(-3, 6)
Step-by-step explanation:
Solve x - 2 > -5 for x as follows: Add 2 to both sides, obtaining x > -3. To graph this, find -3 on the number line and put a circle there. Draw a solid line from this circle towards the right.
Solve x - 2 < 4 for x as follows: Add 2 to both sidees, obtaining x < 6. Find 6 on the number line and put a circle there. Draw a solid line from this circle to the left.
Notice that the two lines you've drawn overlap on the interval (-3, 6). This is the desired solution set.

(7 x 10^5) divided by (2 x 10^2) in standard form
Answer:
3.5x10³
Step-by-step explanation:
7x10^5=700000
2x10^2=200
Divide both by 100
7000÷2=3500
divide by 1000 as standard form is less than 10
1000 is 10 cubed
3500÷1000 is 3.5
