Answer:
[tex]\text{B. }\frac{1}{3}x-3=-x+1[/tex]
Step-by-step explanation:
Let's start by taking a look at the blue line. The slope of any line that passes through two points is equal to the change in y-values over the change in x-values. We can see that the line passes through points (0, 1) and (1, 0). Assign these points to [tex](x_1,y_1)[/tex] and [tex](x_2, y_2)[/tex] (doesn't matter which you assign) and use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let:
[tex](x_1,y_1)\implies (0,1)\\(x_2,y_2)\implies (1, 0)[/tex]
The slope is equal to:
[tex]m=\frac{0-1}{1-0}=\frac{-1}{1}=-1[/tex]
Therefore, the slope of this line is -1. In slope-intercept form [tex]y=mx+b[/tex], [tex]m[/tex] represents slope, so one of the lines must have a term with [tex]-x[/tex] in it, which eliminates answer choices A and D.
For the second line, do the same thing. The red line clearly passes through (0, -3) and (3, -2). Therefore, let:
[tex](x_1,y_1)\implies (0,-3)\\(x_2,y_2)\implies (3, -2)[/tex]
Using the slope formula:
[tex]m=\frac{-2-(-3)}{3-0}=\frac{1}{3}[/tex]
Thus, the slope of the line is 1/3 and the other line must have a term with [tex]\frac{1}{3}x[/tex] in it, eliminating answer choice C and leaving the answer [tex]\boxed{\text{B. }\frac{1}{3}x-3=-x+1}[/tex]
*You can find the exact equation of each line by using the slope formula as shown and plugging in any point the line passes through into [tex]y=mx+b[/tex]

What is exponential function?As the name suggests, the exponential function contains an exponent. Note, however, that the exponential function has a constant as its base and a variable as its exponent, not vice versa (if a function has a variable as its base and a constant as its exponent, it is a power function). The exponential function can be in one of the following forms:
Definition of exponential function
In mathematics, an exponential function is a function of the form f(x) = aˣ. where "x" is a variable and "a" is a constant called the base of the function, which must be greater than 0.
Given, exponential function
f(x) = 4(1/3)ˣ
exponential function is defined for x∈R
Putting x = 3
f(3) = 4(1/3)³
f(3) = 4/27
Hence, 4/27 is value of function f(x) = 4(1/3)ˣ when x = 3

6. Find the area of the figure below. Round to the hundredths place.
Answer:
300.94 sq.m
Step-by-step explanation:
A solid in the shape of cylinder with two hemisphere to each of its ends.
Length of the entire solid = 18 mDiameter of the solid = 7 mRadius of hemisphere , r = 7 / 2 = 3.5 mTo findTotal surface area Formula UsedCurved surface area of hemisphere= 2π ×r ²Curved surface area of cylinder = 2 π × r × hSolution :-Finding, the Curved surface area of cylinder
Calculate the height of cylinder
Height of cylinder = total length of solid - 2 × radius of hemisphereHeight of the cylinder = 18 m - 2 × 3.5= 18 m - 7 mHeight of cylinder = 11 m
Now, we have
Height of cylinder = 11 m
Radius of cylinder = 7 / 2 = 3.5 m
Using Formula :-
Curved surface area of cylinder = 2× π × r × h
Substitute the values
Curved surface area of cylinder = 2π× 3.5m×11m.
Using the value of π = 3.14
Curved surface area of cylinder =2×3.14× 3.5m × 11 m.
multiply, we get.
Curved surface area of cylinder = 241.78 m².
Finding curved surface area of hemisphere
Using Formula
Curved surface area of hemisphere = 2 × π × r²
substitute the values into the formula
Curved surface area of hemisphere = 2 π × ( 3.5 )²
Evaluate the exponent
Curved surface area of hemisphere =2π×12.25m².
Using value of π = 3.14
Curved surface area of hemisphere = 2 × 3 14 × 12.25 m ²
multiply , we get
Curved surface area of hemisphere = 76.93 m².
Find the total areaTotal area of capsules = Curved surface area of cylinder + 2 (Curved surface area of hemisphere)
Total surface area of capsules = 241.78 m²+ 2 × 76.93 m².
Total surface area = 241.78m² + 153.86m².
Subtract and finally we get
Total surface area = 395.64 m ²

Find the value of x and y. Write your answers in simplest form
Answer:
x = 16, y = 8[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{x}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
x = 16
----------------------------------------------------------
Using Pythagoras' identity in the right triangle
y² + 8² = 16²
y² + 64 = 256 ( subtract 64 from both sides )
y² = 192 ( take the square root of both sides )
y = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = 8[tex]\sqrt{3}[/tex]

Answer:
y= 1/2x-3
Step-by-step explanation:
2y - x = 8
First find the slope
2y = x+8
Divide by 2
2y/2 = x/2 +8/2
y = 1/2 x +4
The slope is 1/2 ( y=mx+b where m is the slope and b is the y intercept)
When lines are parallel they have the same slope)
Using y = mx+b
y =1/2x+b
Substituting the point (4,-1) into the equation
-1 =1/2(4)+b
-1 = 2+b
-3 =b
The equation of the line is
y= 1/2x-3

Answer:
a). -65
b). -61
c). -20ab + 3bc +3ac
Step-by-step explanation:
According To the Question,
a). the sum of 72 − 104 + 5 and -32 + 4 - 10 .
(72 − 104 + 5) + (-32 + 4 - 10)(-27) + (-38)-27 - 38 -65b). What should be added to 32 + 32 + 3 to get 3 + 3 , Let X be Added .
Thus, (32 + 32 + 3) + X = 3 + 367 + X = 6X = 6 - 67X = -61c). Subtract the sum of 12ab –10bc –18ac and 9ab + 12bc + 14ac from the sum of ab + 2bc and 3bc – ac.
Thus, [(ab + 2bc) + (3bc – ac)] - [( 12ab –10bc –18ac) + (9ab + 12bc + 14ac)] (ab + 5bc - ac) - (21ab + 2bc - 4ac)ab + 5bc - ac - 21ab - 2bc + 4ac-20ab + 3bc + 3acWhich is the best description for the graph below?
A graph decreases from (0, 3) to (9, 0).
Answer:
Step-by-step explanation:
As we move from (0, 3) to (9, 0), we see x increasing by 9. This is the 'run.'
At the same time, we see y decreasing by 3. This is the 'rise.'
The slope of this line (graph) is m = rise / run = -3/9, or m = -1/3
Since we witness a decrease in y as we move from the first point to the second, we immediately suspect that the slope is negative.
