Given the function h(x) = -x2 -X2 – 5x + 8, determine the average rate of change of the function over the interval -4 < x < -2
Hi there!
[tex]\large\boxed{\text{Average rate = 1}}[/tex]
We can calculate the average rate of change using the following:
[tex]ARC = \frac{f(b)-f(a)}{b-a}[/tex]
Thus, we can plug in the endpoints of -4 and -2. Find the corresponding y-values for these x-values:
f(-2) = -(-2)² - 5(-2) + 8 = -4 + 10 + 8 = 14
f(-4) = -(-4)² - 5(-4) + 8 = -16 + 20 + 8 = 12
Plug in the solved for values into the ARC equation:
[tex]ARC(slope) = \frac{14-12}{-2(-4)} = \frac{2}{2} = 1[/tex]

36 + (12 - 8) + 2 × 5
Answer:
50
Step-by-step explanation:
To answer this we need to use the PEMDAS strategy, first solve any questions in parentheses, next solve all multiplication and division problems from left to right. Next, solve all addition and subtraction problems from left to right.
36 + (12 - 8) + 2 × 5
36 + 4 + 2 x 5
36 + 4 + 10
40 + 10
50
Answer:
[tex]50[/tex]
Step-by-step explanation:
Follow the PEMDAS order of operations:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction.
Calculate the Parentheses- (12-8)
This will equal 4.
[tex]36+4+2x5[/tex]
(x= times)
Multiply and divide, left to right.

(x+y) (x+y) - (x-y) (x-y)
Answer:
4xy
Step-by-step explanation:
(x+y) (x+y) - (x-y) (x-y)
(x² + xy + xy + y²) - (x² - xy - xy + y²)
(x² + 2xy + y²) - (x² - 2xy + y²)
x² + 2xy + y² - x² + 2xy - y²
x² - x² + 2xy + 2xy + y² - y²
4xy
Answer:
that could literally be anything, as long as the first sum is greater then the second.
example;
(2+4) (3+5) - (6+1) (5+2)
(or, 6+8 = 14, 7+7 = 14, 14 - 14 = 0)
hope this helped :)

Answer:
n=10.
Step-by-step explanation:
[tex]\frac{45}{n^{2}-3n-4 }[/tex] - [tex]\frac{3}{n-4}[/tex] = [tex]\frac{2}{n+1 }[/tex]
[tex]\frac{45}{n^{2}-3n-4 }[/tex] - [tex]\frac{3(n+1)}{(n+1)(n-4)}[/tex] = [tex]\frac{2(n-4)}{(n+1)(n-4) }[/tex]
[tex]\frac{45}{n^{2}-3n-4 }[/tex] - [tex]\frac{3n+3}{n^{2} -3x-4}[/tex] = [tex]\frac{2n-8}{n^{2} -3x-4 }[/tex]
45-3n-3=2n-8
45-3+8=5n
n=50/5=10
NO LINKS ACCEPTED -The robot factory is a learning center where children can build robots. The project fee per visit is $15 and each hour of time (x) at the factory costs $4. Jesse goes to the robot factory one afternoon and was charged $40 for the visit. Write an equation that models this situation where X is the number of hours Jesse stands at the robot factory
Answer:
15 + 4x = 40
Step-by-step explanation:
To construct this equation, we'll list all the values we will include first.
The total fee equals $40, so we'll put 40 on one side of the equation.
On the other side, we have to put the values that make up the total. The fee is made with the project cost plus the hourly rate. The first part of this is the beginning cost, $15. Added to this is the hourly cost, $4, times the number of hours spent. So, the other side of the equation is 15 (the starting cost) plus 4 (the rate) times x (the unknown number of hours).
So, our equation is 15 + 4x = 40.
Good luck ^^

A worker places tape around a rectangular shipping label that is 2 times longer than it is wide. How much tape does the worker need? The width is 74mm
Answer:
444 :) (angel number, haha)
Step-by-step explanation:
it needs 74 times 2 mm which is 148 I think, which will also be the length since 148 is 2 times more than 74
so it's : 74 + 74 + 148 + 148 which is basically just 148 times three, so the answer is 444!
can u help please :)
Answer:
z = 8
Step-by-step explanation:
All angles inside a triangle add up to 180 so:
90 + 40 + 5z + 10 = 180
5z + 140 = 180
5z = 40
z = 8
Lily walks 2 kilometers during each trip to school. Write an equation that shows the
relationship between the number of trips x and the total distance walked y.
Answer:
y = 2x
Step-by-step explanation:
Total distance walked = y
Number of trips = x
Lily walks 2 kilometers during each trip to school
Equation that shows the
relationship between the number of trips x and the total distance walked y:
y = 2x
For example, if the number of trips (x) is 3
Total distance walked,y = 2(3)
y = 6 kilometers

Heather has a bag of 15 red, 11 orange, 9 yellow, 12 green, 6 blue and 11 purple markers. how many times would you expect heather to pick a red marker if she picked a marker 90 times?
A.about 11 times
B.about 15 times
C.about 21 times
D.about 64 times
Answer:
B should be the correct answer.
Step-by-step explanation:
15 + 11 + 9 + 12 + 6 + 11 = 64
64<90
Answer:
15 red out of 64 total markers
15 / 64 = .234375
90 x .234375 = 21.09375
so she will pick a red marker about 21 times

Look at the drawing of a triangle within a rectangle. The
triangle and the rectangle have the same base, b, and
height, h.
If the area of the triangle is 48 square units, what is the
total area of sections 1 and 2?
square units
) Intro
Answer:
48 square. Units
Step-by-step explanation:
Given that :
Triangle and rectangle have the same base, b and height, h
AREA of triangle = 0.5 * base * height
48 = 0.5 bh
bh = 0.5 * 48
bh = 96
Total area of section 1 & 2 :
bh = area of triangle + x
X = bh - area of triangle
X = 96 - 48
Area of se tion 1&2 = 48

Please help me with this !!
Answer:
Step-by-step explanation:
a = 1
b = 6
c = 6
axis of symmetry = -(6) / 2*1
= -6 /2
= -3
vertex = ( -3, -3 ) :)
Answer:
Step-by-step explanation:
a = 1 because if is not written what x^2 multiply, it means that x^2 multiply 1
b = 6 b is the term that multiply x
c = 6 c is the therm without x
axis of symetry = -6/2 = -3
the x of vertex is same of the axis of the symmetry so it is -3
if we subistute x with this value we can find the y of vertex
(-3)^2 + 6(-3) + 6 = 9 -18 + 6 = -3
Vertex (-3, -3)

Answer:
∠CBE = 59°
Step-by-step explanation:
Adjacent angles of a parallelogram are supplementary.
∠BCD +∠CDE = 180°
∠BCD +∠CDB +∠BDE = 180°
(21x -5) +34 +(4x+1) = 180
25x +30 = 180
25x = 150
x = 6
∠CBE = ∠CDE = 34 +(4x +1) = 4x +35 = 4(6) +35
∠CBE = 59°

Step-by-step explanation:
Remark
Technically, we can't. We have no way of knowing what kind of figure we are working with. We can say to you that if this is not at least a parallelogram then no answer is possible.
Opposite sides of a parallelogram are equal.
Equation
2x = x + 5
Solution
Subtract x from each side
2x - x = 5
x = 5

Answer:
B. -4y^17
Step-by-step explanation:
A variable y varies directly with x and the constant of variation is 3. What is the value of y when x = 2?
Answer:
y = 6
Step-by-step explanation:
y varies directly with x
y = k*x
Where,
k = constant of variation
Find y when x = 2 and constant of variation,k =3
y = k*x
y = 3 * 2
y = 6
Check:
if y = 6 and x = 2, find k
y = k*x
6 = k*2
6 = 2k
k = 6/2
k = 3
