Answer:
-6x+7
Step-by-step explanation:
Start by multiplying (x-1) by -4 and (x+1) by -2.
Then you will have the equation 5-4x+4-2x-2
Next, just find your like-terms.
Your like-terms are 5,4,-2 and -4x, 2x
Then, for easier for calculation, just use the equation:
-4x-2x+5x+4-2
Your final answer should then be:
-6x+7

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)
Answer:
(3,-4)
Step-by-step explanation:
You can find the vertex where x = -b/2a
To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c
y = 2(x^2 - 6x + 9) - 4
y = 2x^2 - 12x + 18 - 4
y = 2x^2 - 12x + 14
In this equation, a = 2 and b = -12.
So let's plug that into x=-b/2a
x = -(-12)/2(2)
x = 12/4
x = 3
Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.
y = 2(x - 3)^2 - 4
y = 2(3 - 3)^2 - 4
y = -4
The temperature on a spring day is 70 degrees. The temperature increases by 1 degree every hour. Which of the following representations does not show the relationship between the number of hours (h) elapsed and the temperature (T) it has reached?
Answer:
B. [tex]T=h[/tex]
*Sorry, I'm probably too late
Step-by-step explanation:
If the answer was [tex]T=h[/tex], the starting temperature would be [tex]0[/tex]. This is wrong because the starting temeperature is supposed to be [tex]70[/tex].

Answer:
100% is 9, 55% is 4.95, 75% is 6.75.
Step-by-step explanation:
Suppose that 100% were [tex]x[/tex]. Then 30% is 27, so [tex]0.3x=27[/tex] and we can divide both sides by 0.3 to see that [tex]x=\frac{27}{0.3}=\frac{27}{\frac{3}{10}} = \frac{27\cdot 10}{3} = 90.[/tex] So 55% is [tex]0.55x = 0.55 \cdot 9 = 4.95[/tex] and 75% is [tex]0.75x = 0.75\cdot 9=6.75[/tex]. (Note that we can divide the value of a percentage by 100 - the same as moving the comma by two places to the left - to get the decimal value.)
what is y = 5/3x + 2
Answer:
Solving for x : x = 3y/5 - 6/5. Solving for y : y= 5x/3 +2
Step-by-step explanation:
Solving for x: Solve for x by simplifying both sides of the equation, then isolating the variable.
Solving for y: Combine 5/3 and x.
You didn't say which one to solve for so I put out both for you.

Solve the following equations:
x/3+1=7/5
Answer:
8/5..............…is the answer
Answer:
Standard Form: 6/5 Mixed Number: 1 1/5 Decimal: 1.2
Step-by-step explanation:
1. Subtract 1 from both sides of the equation
x/3 + 1 = 7/5
x/3 + 1 - 1 = 7/5 - 1
2. Simplify
2a.
x/3 + 1 - 1 = 7/5 - 1
x/3 = 7/5 - 1
2b.
x/3 = 7/5 - 1
x/3 = 2/5
3. Multiply all terms by the same value to eliminate fraction denominators
x/3 = 2/5
3 x x/3 = 3 x 2/5
4. Simplify
4a. Cancel multiplied terms that are in the denominator
cross out the threes in 3 x x/3 then you should get x = 3 x 2/5
4b. Multiply the numbers
x = 3 x 2/5
x = 6/5
And your answer should be 6/5|
I hope this helps you or anyone
Simplify:
√3 (√3+x)
A. (3+x)√3
B. 2x√3
C. 3+x√3
(I'll mark brainliest if you explain and show your work)
Answer:
C
Step-by-step explanation:
[tex]\sqrt{3}[/tex] times [tex]\sqrt{3}[/tex] = 3 and [tex]\sqrt{3}[/tex] times x = [tex]\sqrt{3}[/tex]x
So that means that answer is 3+[tex]\sqrt{3}[/tex]x which is C
Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it
Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
Answer:
0.98
Step-by-step explanation:
3n-6=-8(6+5n)
3n-6=-48-40n
3n=-48-40n+6
40n+3n=-42
43n=-42
n=0.98 (I rounded it)
Solve for the measure
Answer:
A) 130°
Step-by-step explanation:
Angle UTV = angle YTX = 75°
Angle VTW = 55°
so UTW = 75 + 55
if this helps, please give brainliest if possible
Answer:
A
Step-by-step explanation:
∠ UTV = ∠ YTX = 75° ( vertically opposite angles )
∠ VTW = 55° ( angle at centre is equal to arc that subtends it )
Then
∠ UTW = ∠ UTV + VTW = 75° + 55° = 130° → A
what is the gradient of (0,3) and (1,8)
Answer: 5/1 = 5
Step-by-step explanation:
The gradient is the slope of something. The slope = rise/run so you just do 8-3 = 5 is the rise and then 1-0 = the run so its a gradient of 5
Katrina bought a new sofa. She was able to pay $100 at the
time she received the sofa. She will pay $22 each month on
the balance. The original cost of the sofa was $298. The
equation 100 + 22 = 298 represents this situation.
Use the equation to determine how many months will it take
Katrina to pay off the sofa.
================================================
Work Shown:
100 + 22x = 298
22x = 298-100 ........ subtracting 100 from both sides
22x = 198
x = 198/22 .............. dividing both sides by 22
x = 9
It will take 9 months for her to pay off the sofa.
She pays the original $100, and then on top of that, she pays an extra 22*x = 22*9 = 198 dollars since she paid $22 per month for 9 months. So this leads to 100+198 = 298 dollars total to help confirm our answer.
