if f(x) = 2x-5, which expression represents f(x+1)
Answers
Insert the value of x which is x+1 ->
F(x+1)= 2(x+1)-5
Distribute ->
F(x+1)=2x+2-5
Then, add like terms->
F(x+1)=2x-3
Answer: The required expression for f(x+1) is 2x-3.
Step-by-step explanation: We are given the following function :
[tex]f(x)=2x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to find the expression for f(x+1).
To find the expression for f(x+1), we need to substitute x+1 in place of x in (i).
So, we get from expression (i) that
[tex]f(x+1)\\\\=2(x+1)-5\\\\=2x+2-5\\\\=2x-3.[/tex]
Thus, the required expression for f(x+1) is 2x-3.

The side length of the smallest square plate is 21.2 units.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, length of diagonal on the square is 30 cm.
Let the side of a square be x.
Now, x²+x²=30²
2x²=900
x²=450
x=√450
x=21.2 units
Therefore, the side length of the smallest square plate is 21.2 units.

Which graph represents the solution set of the system of inequalities?
{−2x+y≤4
y>x+2
Answers
The correct graph is:
First graph
Step-by-step explanation:The first inequality is:
[tex]-2x+y\leq 4[/tex]
The graph of this inequality is a straight solid line ( since the inequality is a inequality with a equality sign i.e. not strict ) which passes through (-2,0) and (0,4) and the shaded region is towards the origin as it passes the zero point test.
The second inequality is:
[tex]y>x+2[/tex]
is a dotted straight line (since the inequality is strict) which passes through (-2,0) and (0,2) and the shaded region is away from the origin as it fails the zero point test.
Hence, the correct graph is the first graph.

A rectangle is cut in half along the diagonal to form a triangle. if the area of the triangle is (2x + 10) cm^2, what is the area of the rectangle? Please provide steps and reason for your answer too!
Answers
the triangle's area (a)=(1/2)*(b) (the rectangle's area) we can multiply 2 to both sides to get 2*a=b. Since a is (2x+10), we can plug it in and use the distributive property (since we just can't add up variables and integers) to get
2*(2x+10)=4x+20=b

What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
The table given is:
Type of Insurance Coverage= {Coverage Limits} and {Annual Premiums}

Property Damage $25,000 $120. 50
Collision $500 deductible $275. 75
Comprehensive $100 deductible $100. 00
Her total annual premium = 31.75 + 120.50 + 275.75 + 100 = $528
Discount offered to her = 4.5% of $528 = (in dollars)
The new premium that she needs to pay after discount = Old premium - discount = $528 - $23.76 = $504.24

A hose fills a tank at a rate of 20 gallons per minute.
What is the rate in liters per hour?
(1 gallon ≈ 3.79 liters)
Answers
Answer:
[tex]\frac{4548}{1}[/tex] liters per hour.
Step-by-step explanation:
Given : A hose fills a tank at a rate of 20 gallons per minute.
To find : What is the rate in liters per hour?
Solution : We have given
A tank can fill hose in 1 minute = 20 gallon .
1 gallon = 3.79 liters.
20 gallon = 20 * 3.79 = 75.8 liters.
20 gallon = 75 .8 liters.
So,
A tank can fill hose in 1 minute = 75.8 liters.
A tank can fill hose in 60 minute = 75.8 * 60 liters = 4548 liters.
A tank can fill hose in 1 hour = 4548 liters.
Rate = [tex]\frac{4548}{1}[/tex] liters per hour.
Therefore, [tex]\frac{4548}{1}[/tex] liters per hour.

Wyatt’s eye-level height is 120 ft above sea level, and Shawn’s eye-level height is 270 ft above sea level. How much farther can Shawn see to the horizon? Use the formula mc024-1.jpg, mc024-2.jpg with d being the distance they can see in miles and h being their eye-level height in feet.
Answers
d = √ [ 3h / 2], for h > 0
where d is the distance they can see in miles, and h is their eye-level height in feet.
In the case of Wyatt, h = 120 ft
=> d = √ [ 3(120) ] / 2 = √180 = 13.42 miles
In the case of Shawn, h = 270 ft
=> d = √ [ 3 (270) / 2 ] = √ 405 = 20.12 miles
Given that the question is how much farther Shawn can see to the horizon, you must find the difference:
20.12 miles - 13.42 miles = 6.7 miles
Answer: 6.7 miles

What is the value of a if the point (–4, a) is also on the line?If a line passes through the point (4, –2) and has a slope of 1/2, its equation can be written in point-slope form as:
y - (-2) = 1/2(x - 4)
Simplifying the equation gives:
y + 2 = 1/2x - 2
To find the value of a, substitute x = -4 and y = a into the equation:
a + 2 = 1/2(-4) - 2
a + 2 = -4
a = -6
Hence, the value of a is -6

Because we don't get the same length (for XY and ZW), this means that the segments are not congruent.
-------------------------------------------------------------
To find the length of segment XY, you can count the number of spaces between -7 and -3 to get 4 units. Or you can subtract and use the absolute value notation to ensure the result is positive
|-7-(-3)| = |-7+3| = |-4| = 4
Do the same for segment ZW.

The perimeter of a rectangle is 900 yards. what are the dimensions of the rectangle if the length is 70 yards more than the width?
Answers
900:4= 225
So, now we know each side is 225 Yards first..
Now, since the length is 70 yards longer than the width, we know that:
Length: 225+70= 295
Respectively, we also know that the width is 70 yards shorter since the length is already 70 yards longer:
Width: 225-70=155
Checking answer: (295*2) + (155*2) = 900 Yards
As our final answer, the dimension of the rectangle is 295 yards (Length) by 155 yards (Width)

a2 – 8a + 64
a2 – 4a + 64
a2 – 4a + 16
a2 – 8a + 16
Answers
I believe it is the first one
Final answer:
The number 59 is prime, and the trinomial a^2 - 4a + 4 is a perfect square trinomial.
Explanation:
Prime number: The number 59 is prime because it is only divisible by 1 and itself, while the other numbers have factors other than 1 and themselves.
Perfect square trinomial: The trinomial a2 - 4a + 4 is a perfect square trinomial because it can be factored to (a - 2)(a - 2), making it a square of a binomial.
Talia is packing a moving box. She has a square-framed poster with an area of 9 square feet. The cube-shaped box has a volume of 30 cubic feet. Will the posture lie flat in the box?
Answers
length of the poster = sqrt (9 ft^2) = 3 ft
length of the cube = cbrt (30 ft^3) = 3.11 ft
Since, the length of the cube is longer compared to the length of the poster then, the poster will lie flat on the cube.
Answer: Yes, the posture will be lie flat in the box.
Step-by-step explanation:
since we have given that
Area of square framed poster = 9 sq. feet
Volume of cube shaped box = 30 cubic feet.
As we know the formula for "volume of cube":
[tex]Volume=30\\\\a^3=30\\\\a=\sqrt[3]{30}=3.10\ feet[/tex]
So, Area of cube shaped box would be
[tex]6a^2=6\times (3.1)^2=57.9\ ft^2[/tex]
Since the cube box is large enough so that the posture will lie flat in the box.
