A. Function B has a greater rate of change because it's rate of change is 4/3
B. Function A has a greater rate of change because it's rate of change is 4/3
C. Neither function has a greater rate of change because their slopes are both 4/3

the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality

Which equation for g(x) represents the transformation of f(x) given that f(x) =x^2
g(x) = f(x) shifted right 2 units
Help!!
Answers
Answer:
g(x) = (x - 2)²
Step-by-step explanation:
If we want to shift a function to the right, we subtract the number we are asked to move to the right inside the function's argument:
⇒ To shift f(x) b units to right → f(x - b)
Similarly, in function notation, if we want to shift a function to the left, we add the number we are asked to move to the left inside the function's argument:
⇒ To shift f(x) b units to left → f(x + b)
Given function f(x) = x²
Shift 2 units to the right: f(x - 2) = (x - 2)²
Therefore, g(x) = (x - 2)²
----------------------------------------------------------------------
Additional info:
g(x) = (x - 2)²
= (x - 2)(x - 2)
= x² - 4x + 4

Answers
The possible number of solutions to the equations in the system is 2. A solution is a collection of data designated to the unexplored variables.
What is the solution?A solution is a set of values assigned to the unknown variables that ensure the equation's equality.
To put it another way, a solution is a value or a set of values (one for each unknown) that, when substituted for the unknowns, makes the equation equal.
The given system of equation is;
[tex]x^2+y^2=9[/tex]
The standard equation of the circle is;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
On comparing the given equation with the standard equation;
The first equation shows the center is at origin(0,0). and radius is 3.
The second equation shows the given equation is a straight line.
As we know that a straight line can only intersect a circle at a maximum of 2 points.
Hence the possible number of solutions to the equations in the system is 2.

A nonagon has angles that measure 150°, 130°, 130°, 150°, 140°, 140°, 150°, 130°, and d. What is d?
Answers
Answer:
d = 140°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
a nonagon has 9 sides , then
sum = 180° × 7 = 1260°
sum the angles and equate to 1260
150° + 130° + 130° + 150° + 140° + 140° + 150° + 130° + d = 1260°, that is
1120° + d = 1260° ( subtract 1120° from both sides )
d = 140°

x = 8
Step-by-step explanation:
11x - 34 and 7x - 2 are vertical angles and congruent, thus
11x - 34 = 7x - 2 ( subtract 7x from both sides )
4x - 34 = - 2 ( add 34 to both sides )
4x = 32 ( divide both sides by 4 )
x = 8
-----------------------
11x - 34 = 11(8) - 34 = 88 - 34 = 54
18y and 11x - 34 are adjacent angles and supplementary , thus
18y + 54 = 180 ( subtract 54 from both sides )
18y = 126 ( divide both sides by 18 )
y = 7

Answers
Answer:
20 caramel apples are covered with sprinkles
Step-by-step explanation:
Let the fraction representing total number of apples = 120 = 1
We are told in the question:
1/5 of the caramel apple are covered with peanuts 1/3 are covered with chocolate chips 3/10 are covered with coconut The rest with sprinkles
Hence:
1 = 1/5 + 1/3 + 3/10 + Sprinkles
Sprinkles = 1 - (1/5 + 1/3 + 3/10)
LCM = 30
1 - (6 + 10 +9/30)
1 - 25/30
1 - 5/6
Fraction of caramel apples covered sprinkles = 1/6
The number caramel apples covered with sprinkles = 1/6 of 120 caramel apples
= 1/6 × 120
= 20 caramel apples are covered with sprinkles

Given the definitions of f(x) and g(x) below, find the value of g(f(0))
f(x)= -x+9
g(x)=x^2 - 6x+9
Answers
Answer:
The value of g(f(0)) is 36
Step-by-step explanation:
g(f(x)) is a composite function, where f(x) is the value of x in g(x), which means substitute x in g(x) by f(x)
Let us use this rule to solve our question
∵ f(x) = -x + 9
∵ g(x) = x² - 6x + 9
→ Substitute x in g by f
∵g(f(x)) = g(-x + 9)
∴ g(f(x)) = (-x + 9)² - 6(-x + 9) + 9
→ Let us simplify it
∵ (-x + 9)² = (-x)(-x) + (-x)(9) + (9)(-x) + (9)(9)
∴ (-x + 9)² = x² + -9x + -9x + 81
→ Add the like terms (-9x + -9x)
∴ (-x + 9)² = x² + -18x + 81
→ Remember (+)(-) = (-)
∴ (-x + 9)² = x² - 18x + 81
∵ - 6(-x + 9) = -6(-x) + (-6)(9)
∴ - 6(-x + 9) = 6x + -54
∴ - 6(-x + 9) = 6x - 54
→ Substitute them in g(f(x))
∴ g(f(x)) = x² - 18x + 81 + 6x - 54 + 9
→ Add the like terms
∴ g(f(x)) = x² + (-18x + 6x) + (81 -54 + 9)
∴ g(f(x)) = x² + (-12x) + (36)
∴ g(f(x)) = x² - 12x + 36
→ Now substitute x by 0
∴ g(f(0)) = (0)² - 12(0) + 36
∴ g(f(0)) = 0 - 0 + 36
∴ g(f(0)) = 36
There is an easy way to find it quickly
Substitute x in f by 0
f(0) = -(0) + 9
f(0) = 9
Substitute x in g by 9
Find g(9)
g(9) = (9)² - 6(9) + 9
g(9) = 81 - 54 + 9
g(9) = 36

3. triangle: 16 ft²; semicircle: 6.28 ft²; rectangle: 48 ft²
4. 57.72 ft²
Step-by-step explanation:
2.The area that needs to be painted can be found by determining the overall area of the shape and subtracting the area that is not painted.
__
3.The area of the triangle is given by the formula:
A = 1/2bh
A = 1/2(8 ft)(4 ft) = 16 ft²
The area of the semicircle is ...
A = 1/2πr²
A = 1/2(3.14)(2 ft)² = 6.28 ft²
The area of the rectangle is ...
A = bh
A = (8 ft)(6 ft) = 48 ft²
__
4.The triangle and rectangle are painted. They constitute the overall shape of the set piece. The semicircular window is a hole, so does not need to be painted. Then the painted area is ...
triangle area + rectangle area - semicircle area
= 16 ft² +48 ft² -6.28 ft² = 57.72 ft² . . . painted area
What is the equation of the line that passes through the point -4, —8) and has a
slope of 4?
Answers
Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8
