f(x) =2x squared - 5x - 3 g(x) = x squared + 6x - 1 what is h(x), if h(x) = g(x) - f(x)
Answer:
-2x^2 + x^2 +11x +2
Step-by-step explanation:
f(x) = 2x^2-5x -3
g(x) = x^2 + 6x -1
h(x) = g(x) - f(x)
x^2 + 6x -1 - 2x^2 +5x +3
-2x^2 + x^2 +11x +2

What is the value of x^6+y^2x 6 +y 2 x, start superscript, 6, end superscript, plus, y, squared when x=1x=1x, equals, 1 and y=11y=11y, equals, 11?
Try 122.
Step-by-step explanation:
Since x = 1, x^6 = 1.
Since y = 11, 11^2 = 121.
1 + 121 = 122.
So, the value of x ^ 6 + y ^ 2 = 122.Answer:82

What will be the return value of =SUM({10;15;20;25;30})?
Answer:
The return value is 100
Step-by-step explanation:
Given
[tex]=SUM({10;15;20;25;30})[/tex]
Required
Determine the return value
In Microsoft Office Excel, the sum of values is represented as:
[tex]=SUM({a_1;a_2;a_3;.....;a_n})[/tex]
This is interpreted as:
[tex]SUM= a_1;a_2+a_3+.....+a_n[/tex]
So, in the case of:
[tex]=SUM({10;15;20;25;30})[/tex]
The return value is:
[tex]Value= 10 + 15+ 20 + 25 + 30[/tex]
[tex]Value= 100[/tex]
Hence, the return value is 100
100 - (25 + 40) +5 What is the answer?
Answer:
100-25=75 75+40=115 115+5=120
Answer:
The answer is 40.
Step-by-step explanation:
100 - (25+40) +5
100- (65) +5
35 +5
= 40

Answer:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
Width = 55ft
Area = 4950 sq ft
Cost = $9900
Step-by-step explanation:
Derrick mistakenly combined the numbers adding it together but the numbers are not the same value to be combined. You cannot add yards and ft together.
You have to convert the yards to ft to add it to the other ft.
1 Yard = 3 ft
So the width is 18 yards 1 ft = 54ft + 1ft = 55ft
To calculate the area is L x W
The length is 30 yards. Convert that to ft = 90ft
So 90 x 55 = 4950 sq ft
At $2 per sq ft, you multiply the 4950 sq ft by $2
2 x 4950 = $9900
The equation y = 3.5x represents the total cost y in dollars of buying x pounds of cheddar cheese at Art’s Deli. The graph below shows the total cost y in dollars of buying x pounds of cheddar cheese at Jon’s Deli. What conclusion can you draw about the cost of cheddar cheese at these delis? Cheddar cheese costs $4 more per pound at Jon’s Deli than Art’s Deli. Cheddar cheese costs $0.50 more per pound at Jon’s Deli than Art’s Deli. Cheddar cheese costs $3.50 less per pound at Art’s Deli than Jon’s Deli. You pay the same price per pound for cheddar cheese at both delis.

What are the interest cost and the total amount due on a six-month loan of $1,800 at 14.4 percent simple annual interest
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Principal (P)= $1,800
Number of periods (t)= 6 months
Monthly interest rate (r)= 0.144/12= 0.012
To calculate the interest to be paid and the total amount due, we need to use the following formula:
I= P*r*t
I= 1,800*6*0.012
I= $129.6
Total amount= $1,929.6

Which inequality describes all the solutions to -5x + 6 < 2(-3 − x)?
Answer: x>4
Step-by-step explanation:
The solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.
The given inequality is 5x + 6 < 2(-3 - x).
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality can solved as follows:
5x + 6 < 2(-3 - x)
Multiply 2 to the bracket
5x + 6 < -6 - 2x
Add 2x to both the sides of inequality
5x + 6 + 2x < -6 - 2x + 2x
⇒7x+6<-6
Subtract 6 to both the sides of inequality
7x+6-6<-6-6
⇒7x<-12
Divide 7 to both the sides of inequality
7x/7<-12/7
⇒x<-12/7
⇒x<-1.7
Solution set = {-2, -3, -4, -5, -6,.......}
Therefore, the solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

Find the height of an equilateral triangle with side length 8.
Answer:
U need to just do
[tex] \sqrt{3 \div 4} a {}^{2} [/tex]
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
The segment from a vertex to the side opposite is a perpendicular bisector.
The equilateral Δ is divided into 2 right triangles with legs 8 and 4
let height be h, then using Pythagoras' identity
h² = 4² + 8² = 16 + 64 = 80 ( take the square root of both sides )
h = [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex] ← exact value
