Answer:
[tex]f(2x) = 8x^{2} +3[/tex]
Step-by-step explanation:
f (x) = 2x²+3
f(2x) = [tex]2(2x)^{2}[/tex] + 3
f(2x) = [tex]2(4x^{2} )[/tex] + 3
f(2x) = [tex]8x^{2}[/tex] + 3
how do you solve 5y-2=10y-4
Answer:
y=2/5
Step-by-step explanation:
Using the power of inequalities, first, change the -2 to a positive by adding it to both sides of the equation. Second, get 10y and make it into a negative by subtracting it from both sides of the equation. Lastly, divide each side.
5y-2=10y-4
5y+2=10y+2
__________
5y=10y-2
-10y=-10y-2
__________
-5y=-2: Then Divide negative -5 in which your final answer should be y=2/5

Answer:(-5,4)
Step-by-step explanation:
given the equation y= - 3x + 2.5 answer the following when X is 1 what value of Y makes the equation true part B when x is -1.5 what value of y makes the equation true? part c when y is 8.5 what value of x makes the equation true
Answer:
y = -0.5y = 7x = -2Step-by-step explanation:
Fill in the given values and solve for the remaining variable.
a) y = -3(1) +2.5
y = -0.5
__
b) y = -3(-1.5) +2.5 = 4.5 +2.5
y = 7

A quilt piece is designed with four congruent triangles to form a rhombus so that one of the diagonals is equal to the side length of the rhombus. A rhombus with diagonals is shown. The diagonals form 4 triangles. All sides are 4 inches long. The distance from the top point to the middle point is 2 inches. The distance from the right point to the middle point is x. One interior angle is 30 degrees and another is a degrees. Which measures are true for the quilt piece? Select three options. a = 60° x = 3 in. The perimeter of the rhombus is 16 inches. The measure of the greater interior angle of the rhombus is 90°. The length of the longer diagonal is approximately 7 inches.
Answer:
1) a = 60°
3) The perimeter of the rhombus is 16 inches.
5) The length of the longer diagonal is approximately 7 inches.
Step-by-step explanation:
From the attached diagram, we begin to compare the options
1)a = 60°
From the question, we are told that:
One interior angle is 30 degrees and another is a degrees
The sum of angles in a rhombus = 360°
There are 4 angles in a rhombus and each angle should normally be equal to 90° hence,
a = 90° - 30°
a = 60°
2) x = 3 in.
Looking at the attached diagram,
We solve for x using Pythagoras Theorem
a² + b² = c²
a = 2 inches
b = x = ??
c = 4 inches
Hence,
2² + b² = 4²
b² = 4² - 2²
b² = 16 - 4
b² = 12
b = √12
b = 3.4641016151 inches
Option 2 is incorrect
3) The perimeter of the rhombus is 16 inches.
A rhombus is a quadrilateral with 4 sides that are equal to each other.
The perimeter of a Rhombus = 4a
Where a = Length of the side of a rhombus
From the above question, we are told that, the length of each side = 4 inches
Hence, perimeter = 4 × 4
= 16 inches.
Option 3 is correct
4)The measure of the greater interior angle of the rhombus is 90°.
The measure of the greater interior angle = 2 × a°
a° has already been solved for in option 1 as 60°
Hence,
Measure of the greater interior angle = 2 × 60°
= 120°
Option 4 is not correct.
5)The length of the longer diagonal is approximately 7 inches.
Since the Rhombus forms 4 equal triangles, it means the diagonals are the same.
Hence, the length of the longer diagonal
= 2 × 3.4641016151
= 6.9282032303 inches
Approximately = 7 inches.
Option 5 is correct.
Hence, the correct options are
1) a = 60°
3) The perimeter of the rhombus is 16 inches. The measure of the greater interior angle of the rhombus is 90°.
5) The length of the longer diagonal is approximately 7 inches.

Cwicky Cleaners charges $100 up front plus $20 an hour to clean a house. No Mo Mess charges $50 up front plus $30 an hour
to clean a house. For how many hours is the cost the same for Cwicky Cleaners and No Mo Mess?
Answer:
5 hours
Step-by-step explanation:
Variable x = number of hours
Step 1: set up equations
Cwicky Cleaners: 100 + 20x
No Mo Mess: 50 + 30x
Step 2: to find the same hours equal the two equations
100 + 20x = 50 + 30x
Isolate the variable (x)
100 - 50 = 30x - 20x
50 = 10x
50 ÷ 10 = x
5 = x
Step 3: Check your work
Plug in 5 for x on both sides and equal equations together
100 + 20(5) = 50 + 30(5)
100 + 100 = 50 + 150
200 = 200
If they equal each other, then the answer is correct.
This answer is correct.
Can someone tell me ththe answer??? I’m confused on This one
Answer:
2 hours including the layover (time between arriving and departing at Orleans)
1 hour and 48 minutes without the layover <-- probably this one
Step-by-step explanation:
Answer:
108 minutes = 1.8 hours
Step-by-step explanation:
We need to go from Paris to Limoges in a train via Orleans.
We first saw that the time it takes to go from Paris to Orleans is 29 minutes
So, Paris to Orleans = 29 minutes (Time 1)
Then we saw that the time from Orleans to Limoges is 79 minutes long journey
So, Orleans to Limoges = 79 minutes (Time 2)
Now, the question asks us, how long will it take in train from Paris to Orleans
So, to answer that it will be Time 1 + Time 2 =
=> 29 + 79 = 108 (Total time spent in train)
As the question asks us the time in hours, we can get that by
Total time / number of minutes in one hour
=> 108 / 60 = 1.8 hours
