4x^2-4x=+1 by factoring
Answer:
Below.
Step-by-step explanation:
4x^2 - 4x - 1 = 0
This will not factor.
But 4x^2 - 4x + 1 = 0 will:
= (2x - 1)(2x - 1) = 0
x = 0.5 (*2)
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
Hope this helps, please mark me as brainliest!! Thank you

-8x-27=-7\left(1+2x\right)+2x
Answer:
[tex]x=5[/tex]
Step-by-step explanation:
[tex]-8x-27=-7\left(1+2x\right)+2x[/tex]
Expand:
[tex]-8x-27=-7\times 1-7\times 2x+2x[/tex]
[tex]-8x-27=-7-12x[/tex]
Add 27 to both sides:
[tex]-8x-27+27=-7-12x+27[/tex]
[tex]-8x=-12x+20[/tex]
Add 12x to both sides:
[tex]-8x+12x=-12x+20+12x[/tex]
[tex]4x=20[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4}=\frac{20}{4}[/tex]
[tex]x=5[/tex]
Write the equation for the graph below.

Step-by-step explanation:
Marni has 11 ounces of walnuts. She needs 6 ounces for one recipe and \frac {1}{4} 4 1 pound for another. There are 16 ounces in 1 pound. Does she have enough? 1. To answer this question, you first need to convert all measurements to the same units. Since two of the measurements are in ounces and only one is in pounds, convert \mathbf{\frac {1}{4}} 4 1 pound to ounces. Show your work.
Answer:
Yes she has enough walnuts for her two recipes
Step-by-step explanation:
Total number of walnuts that Marni has = 11 ounces
She has two receipe
First recipe = 6 ounces
Second recipe = 1/4 pounds
Hence,
To find out if she has enough:.we add up the number of ounces from both recipes
The second recipe is in pounds hence, we convert to ounces.
1 pound = 16 ounces
1/4 pound =
Cross Multiply
= 1/4 pounds × 16 ounces/1 pound
= 4 ounces
Hence, we can add up now
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
Since both recipes would require a total of 10 ounces of walnuts and Marin has 11 ounces, we can conclude that Marin has enough ounces of walnuts for her two recipes.

umm first you write down the number of zeros (but only the zeros at last if a zero comes in middle or between other numbers, then you must have to multiply it) and then multiply the remaining numbers. I am not good at explaining. ;)
What is an equation of the line that passes through the points (4,-7) and (-4,5)
Answer:
y = -1.5x -1
Step-by-step explanation:
moves right 8
and down 12
so m = -12/8x or -1.5x
(4,-7) moves up 6, (0, -1)
Step 1: Subtract 3 from both sides of the inequality.
Step 2: __________
Step 3: Divide both sides of the inequality by the coefficient of x.
What is the missing step in solving the inequality 5 – 8x < 2x + 3?
Add 2x to both sides of the inequality.
Subtract 8x from both sides of the inequality.
Subtract 2x from both sides of the inequality.
Add 8x to both sides of the inequality.
Answer:
The missing step is;
Add 8x to both sides of the inequality
Step-by-step explanation:
The step by step solution is presented as follows;
Step 1: Subtract 3 from both sides of the inequality
From the given inequality equation, we have;
5 - 8·x < 2·x + 3
Subtracting 3 from both sides of the inequality gives;
5 - 8·x - 3 < 2·x + 3 - 3
2 - 8·x < 2·x
Step 2: Subtract 8·x from both sides of the resulting inequality
2 - 8·x - 8·x < 2·x - 8·x
2 < -6·x
Step 3: Dividing both sides of the resulting inequality from above by the coefficient of x gives;
2/(-6) < -6·x/(-6)
-1/3 > x.
Answer:
D. Add 8x to both sides of the inequality

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.
For question 4 I know it has the answer already but I just need the steps by step for it its the midpoint formula. If you know can you help me out
Answer:
M = ((-4+5)/2, (-1+3)/2) = (1/2, 2/2) = (1/2, 1)
Step-by-step explanation:
The midpoint (M) of segment AB is ...
M = (A +B)/2
That is, for coordinates A = (ax, ay) and B = (bx, by), the midpoint is ...
M = ((ax, ay) +(bx, by))/2
M = ((ax+bx)/2, (ay+by)/2) . . . . midpoint formula
__
For A(-4, -1) and B(5, 3), M will be ...
M = ((-4+5)/2, (-1+3)/2) = (1/2, 2/2)
M = (1/2, 1) . . . . as you know

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
__
c) 8.5 = -3x +2.5
6 = -3x . . . . subtract 2.5
-2 = x . . . . . divide by -3
find the measure of the angle indicated. please help fast.
Answer:
The measure of the angle indicated is 35 degrees.
Step-by-step explanation:
The missing angle in the left triangle
= 180 - (45 + 87)
= 180 - 132
= 48 degrees.
So the angle external to the triangle on the right
= 48 + 82 = 130 degrees.
By the external angle of a triangle theorem:
130 = 95 + ?
? = 130 - 95
= 35 degrees.
