Answer:
denoted interchange solve
Step-by-step explanation:
y= (2-x)/3 Let f(x) be denoted by y, thus y= -3x+2 Now interchange x and y, it becomes x= -3y+2 Solve for y, y= (2-x)/3 This is f^(-1) x

Answer:
slope is m= y_2-y_1/x_2-x_1 and the y-intercept is where the line crosses over the x-axis
Step-by-step explanation:
fill in the points and do the equation m= rise(y points)/ run(x points)
m=slope
(x_1, y_1) =coordinates of first point in the line

I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?
Answer:
Cost of 110 g bag = $ 0.132
Step-by-step explanation:
As we know ,
1 kg = 1000 g
⇒1000 g = 1 kg
⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg
⇒110 g = 110 (0.001) kg = 0.11 kg
⇒110 g = 0.11 kg
Now,
Cost of 10 kg bag = $12
⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]
⇒Cost of 1 kg bag = $ 1.2
⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132
∴ we get
Cost of 110 g bag = $ 0.132

Find g(-4) if g(x) = 8x^2 + 4x
Answer:
Your answer would be -144
The value of the function g(x) = 8x² + 4x at g(-4) is 112.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, a function g(x) = 8x² + 4x.
Now to obtain the value of g(-4) we'll simply substitute - 4 in place of x.
which is g(-4) = 8(-4)² + 4(-4).
g(-4) = 8×16 - 16.
g(-4) = 128 - 16.
g(-4) = 112.

Step One
Find the supplement of both exterior angles. They both have angles that add with them to make 180 degrees.
x + 105 = 180 Subtract 105 from both sides
x = 180 - 105
x = 75
y + 148 = 180 Subtract 148 from both sides
y = 180 - 148
y = 32
Step Two
There are two ways to conclude the problem. You could find the value of the 3rd angle of the triangle, or you could notice that x is going to be the sum of the 2 angles you just found. These two angles are called the remote interior angle.
Method One
x = 32 + 75
x = 107
Method Two
32 + 75 + y = 180
107 + y = 180
y = 180 - 107
y = 73
The sum of x + 73 = 180
x = 180 - 73
x = 107

[tex]a_{n}[/tex] = 10n + 26
Step-by-step explanation:
[tex]a_{n} = a_{1} + (n - 1)d[/tex]
In your problem d = 46 - 36 = 10 and [tex]a_{1} = 36[/tex]
So, [tex]a_{n}[/tex] = 36 + (n - 1)10
= 36 + 10n - 10
= 10n + 26

Answer:
y = -25x + 170
Step-by-step explanation:
For the graph equation y = ax + b, we have to find a and b.
Pick two points that are on the grid for best accuracy.
e.g., (2,120) and (6,20)
Then a = (20-120)/(6-2) = -25
b is the y coordinate of the line with the y axis: 170
So the formula is:
y = -25x + 170

A project manager has ordered 252 pallets of concrete blocks for a construction project. Casone's trucks can each carry 14 pallets of blocks at a time. The project manager used partial quotients to find the number of delivery trucks to expect. His work is shown at the right. Is his solution correct? Explain
Answer:
18 trucks of delivery
Step-by-step explanation:
Total pallets of concrete blocks ordered = 252 pallets
If each truck can carry 14pallets, then;
1 truck = 14pallets
To determine the number of delivery truck 252pallets can carry, we can express this as:
x truck = 252pallets
Divide both expressions
1/x = 14/252
Cross multiply
14x = 1×252
14x = 252
x = 252/14
x = 18
Hence the manger should expect 1 18 trucks of delivery

Answer:
-12Step-by-step explanation:
Let the equation of the line be x = y - 12
The x intercept occurs at y = 0
Substitute y = 0 into the equation
x = 0 -12
x = -12
Hence the x intercept of the line is -12

You are running the concession stand at a volleyball game, selling hot dogs and cans of pop. Each hot dog costs $1.50 and each soda costs $0.50. At the end of the night you have made exactly $78.50. You know that you have sold exactly 87 items, but cannot remember how many of each. That mean PTA lady will never let you work the concession stand again if you don’t report the correct number of each item sold! How many of each did you sell?
Answer:
Hot Dogs: 35
Soda: 52
Step-by-step explanation:
35 hot dogs + 52 sodas is 87 items.
35 x $1.50 = $52.50
52 x $0.50 = $26.00
$52.50 + $26.00 = $78.50
