Answer:
Average Rate of change of given function [tex]h(x)=-x^2-6x+17[/tex] is 2
Step-by-step explanation:
We are given function: [tex]h(x)=-x^2-6x+17[/tex] (considering x is missed)
We need to find average rate of change of the function over the interval [tex]- 6 < x < -2[/tex].
[tex]x_{1} = -6\\x_2 =-2[/tex]
Formula used to find average rate of change is: [tex]Average \ Rate \ of \ Change =\frac{h(x_2)-h(x_1)}{x_2-x1}[/tex]
Finding f(x₁) and f(x₂)
[tex]We \ have \ x_1=-6\\h(x_1)= -x^2-6x+17\\h(x_1)=-(-6)^2-6(-6)+17\\h(x_1)=-36+36+17\\h(x_1)=17[/tex]
[tex]We \ have \ x_2=-2\\h(x_2)=-x^2-6x+17\\h(x_2)=-(-2)^2-6(-2)+17\\h(x_2)=-4+12+17\\h(x_2)=25[/tex]
Putting values in the formula of average rate of change
[tex]Average \ Rate \ of \ Change =\frac{h(x_2)-h(x_1)}{x_2-x1}\\h(x_2)=25, h(x_1)=17, x_1 =-6 \ and \ x_2=-2\\Average \ Rate \ of \ Change =\frac{25-17}{-2-(-6)}\\Average \ Rate \ of \ Change =\frac{8}{4}\\Average \ Rate \ of \ Change =2[/tex]
So, Average Rate of change of given function [tex]h(x)=-x^2-6x+17[/tex] is 2
Type the integer that makes the following addition sentence true:
-5+? = -8
The answer to this question is -3
Answer:
The answer of -5+?=8
Let ? be x
so, A.T.Q
-5+x=8
we take x Right hand side and -5 left hand side with 8
x=8+5
x=13
so, the answer is -5+13=8
Which angles form a linear pair?
HURRY!! WILL MARK BRAINLIEST!!!
Find the slope of the line.
- 1/3
-3
4
1/4
Answer:
-3
Step-by-step explanation:
First, we find points on the line, (1,1) and (4,1). Then we can use the slope formula, (y2 - y1)/(x2-x1). Plugging those two points into the formula gives -3/1 which is equal to -3.

Answer:
your answer woulsd be 4/15 or how many times does 4 gois in ta 15
Step-by-step explanation:
A student can type
2
3
of a page in
1
5
hour. How many pages can the student type in an hour?
Answer:
A student can type 3.33 pages in 1 hour.
Step-by-step explanation:
(Assuming you mean 2/3 of a page and 1/5 of an hour)
To solve this we need to multiply both sides by 5. This is because when you multiply 1/5 by 5 you get 1 hour and what you do to one side you must do to the other.
1/5 * 5 = 1
2/3 * 5 = 3.3333
Rounding to the nearest hundredth:
3.33
A student can type 3.33 pages in 1 hour.
an internet service provider chargers $18 per month plus an initial set up fee. One customer paid a total of $81 after 2 months. Write an equation modeling this situation on slope- intercept form.
Answer:
y = 18x + 45
Step-by-step explanation:
81 = 18x + b
81 = 18(2) + b
81 = 36 + b
b = 45 so 45$ is the initial set up fee

PB = QC (Given) (S)
BC (common side) (S)
QB = PC (Since ABC is isosceles triangle and PB = QC) (S)
Topic: congruence and similarity
If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!
Answer:
SAS criteriaStep-by-step explanation:
Given is isosceles triangle as AB = AC, it means angles B and C measure same
Triangles PBC and QCB have common side BC, equal sides PB = QC as PB = AB - AP and QC = AC - AQ
So two sides and the angle between are congruent:
BC ≅ BC, PB ≅ QC, ∠PBC ≅ ∠QCBSo ΔPBC≅ΔQCB as per SAS criteriaSuppose a radio station desires to estimate the proportion of the market

-9=2(18)+9y how do you work it out
Answer:
y = -5
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-9 = 2(18) + 9y
Step 2: Solve for y
Multiply: -9 = 36 + 9ySubtract 36 on both sides: -45 = 9yDivide both sides by 9: -5 = yRewrite: y = -5Step 3: Check
Plug in y to verify it's a solution.
Substitute: -9 = 2(18) + 9(-5)Multiply: -9 = 36 - 45Subtract: -9 = -9The Shortest women living is jyoli ange, born on December 16,1993. She measures 24 inches tall. how many feet tall is she

MATH
Answer:
[tex]B=\frac{2A}{h}-b[/tex]
Step-by-step explanation:
To solve this B needs to be isolated. First we must multiply both sides of the equation by 2 to get rid of the fraction on the left side. Next, divide both sides by h to get rid of the h on the left side. Finally, subtract b form both sides to get B by itself.
