HELPP Which equation is related to Vx+10-1-x?
O
x + 10 = x2 + x + 1
O x + 10 = x2 + 2x + 1
O x + 10 = x2 + 1
O x + 10 = x2-1
Answer:x + 10 = x2 + 2x + 1 x + 10 = x2 + 1 x + 10 = x2 – 1.
Step-by-step explanation:
The solution is, x+10 = x^2 + 2x + 1 is the equation is related to
√x+10 - 1 = x.
What is simplification?Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
here, we have,
given that,
the equation is,
√x+10 - 1 = x
or, √x+10 = x+1
now, taking square on both side, we get,
x+10 = (x+1)^2
we have,
(a+b)^2 = a^2 + 2ab + b^2
so, applying that, we get,
x+10 = x^2 + 2x + 1
Hence, The solution is, x+10 = x^2 + 2x + 1 is the equation is related to √x+10 - 1 = x.

Answer:
i dont see the question
Step-by-step explanation:
For what value of q is the equation -13(q + 4) = 7q + 16
Answer:
Q = -3.4
Step-by-step explanation:
Our original equation is: -13(q+4)=7q+16
if we simplify this, we get: -13q-52=7q+16
Subtract 16 from both sides: -13q-68=7q
Add 13q to both sides to get: -68=20q
divide the equation to get this: -3.4=q

Answer:
13.2 miles
Step-by-step explanation:
To solve this, we will need to first solve for the base of the triangle and then use the information we find to solve for the shortest route.
(5.5 + 3.5)² + b² = 15²
9² + b² = 15²
81 + b² = 225
b² = 144
b = 12
Now that we know that the base is 12 miles, we can use that and the 5.5 miles in between Adamsburg and Chenoa to find the shortest route (hypotenuse).
5.5² + 12² = c²
30.25 + 144 = c²
174.25 = c²
13.2 ≈ c
Therefore, the shortest route from Chenoa to Robertsville is about 13.2 miles.

Answer:
there is no solution-
Step-by-step explanation:
there's no solution because its impossible for a to have 2 different values; you see that 0.1 and 0.01 are not equal, therefore a can not be equal,, otherwise the equation would be false
Solve. A standard coffee mug has a capacity of 16 fluid ounces. If Annie needs to fill 6 mugs with coffee, how many total quarts of coffee does she need?
Answer: 3 quarts of coffee.
Step-by-step explanation:
A coffee mug can take 16 fluid ounces.
Annie needs to fill up 6 mugs so the total ounces needed for 6 mugs would be:
= 16 * 6
= 96 fluid ounces
As the answer needs to be in quarts, convert the above.
1 quart = 32 fluid ounces
96 fluid ounces = 96/32
= 3 quarts

y = 4(x + 6)2 + 2
O y = -4x² + 48x + 136
O y = 4x2 + 48x + 146
O y = x² - 48x + 146
O y = -14x2 – 48x – 146
Answer:
2nd option will be the answer (y=4x²+48x+146)
Step-by-step explanation:
y=4(x+6)²+2
y=4(x²+2*x*6+6²)+2 [(a+b)²=a²+2ab+b²]
y=4(x²+12x+36)+2
y=4(x²)+4(12x)+4(36)+2
y=4x²+48x+144+2
y=4x²+48x+146

Answer:
1/6
Step-by-step explanation:
When subtracting or adding fractions, you always want the denominator (aka the bottom number of the fraction) to be the same number. Since both of your denominators are both the same, we can subtract!
2/6 - 1/6 = 1/6
Remember that you don't subtract the bottom, just the top. Hope this helped :)
Rapid Rental Car charges a $55 rental fee, $20 for gas, and $0.65 per mile driven. For the same car, Capital Cars charges $55 for rental and gas and $0.75 per mile.
Answer:
200 miles
Step-by-step explanation:
Given data
Rapid Rental Car
charges a $55 rental fee
$20 for gas, and
$0.65 per mile driven
let the number of miles be x, the total charges y
y=55+20+0.65x
y= 75+0.65x----------1
Capital Cars
charges $55 for rental and gas and
$0.75 per mile.
let the number of miles be x, the total charges y
y=55+0.75x
y= 55+0.75x----------2
Required
The number of miles driven before the two Rental companies charge the same amount
equate 1 and 2
75+0.65x= 55+0.75x
collect like terms
75-55= 0.75x-0.65x
20= 0.1x
x= 20/0.1
x= 200miles
Hence the distance will be 200 miles for the charges to be the same
A new Playstation game system costs $380. The tax on the system is 4%. What is the total cost of the system including tax? *
Answer:
395.2
Step-by-step explanation:
380 x 0.04 = 15.2
380 + 15.2 = 395.2
Answer:
The cost of the system including the tax is $395.20.
Step-by-step explanation:
If the tax is 4% that means that the total price will equal...
380 + (380)(0.04) = $395.20
Therefore the cost of the system including the tax will be $395.20.

What is the inverse of the function
Answer:
second option
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 9 ( add 9 to both sides
y + 9 = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = x + 9

Answer: 28 degrees
Step-by-step explanation:
Since angle KJL = LJM then that means angle 7x=3x+16
First we need to solve for x
7x=3x+16
4x=16
x=4
now we can input it into either equation to solve for the angle KJL
7(4)= 28 so the angle is 28 degrees
Which functions are linear Select all that applies A) s=4r - 2 B) s=r + 10 C) s= 9r - 7 D) s=6r + 6
Step-by-step explanation:
The graph of linear function is a straight line.
General form of the linear function is -
y = a + bx
where a is the y -intercept and b is the slope.
Both a and b are constants.
Here,
x is independent variable whereas y is dependent variable.
For example -
y = 2x + 15

The diagram shows triangle ABC. Calculate the length of AC
Given:
In triangle ABC, AB=8.2 cm, C=13.5 cm and angle A= 81 degrees.
To find:
The length of AC.
Solution:
According to the Law of Sines:
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]
Using Law of Sines, we get
[tex]\dfrac{\sin A}{a}=\dfrac{\sin C}{c}[/tex]
[tex]\dfrac{\sin (81^\circ)}{13.50}=\dfrac{\sin C}{8.2}[/tex]
[tex]\dfrac{\sin (81^\circ)\times 8.2}{13.50}=\sin C[/tex]
[tex]\sin^{-1}\dfrac{\sin (81^\circ)\times 8.2}{13.50}= C[/tex]
[tex]C\approx 36.86^\circ[/tex]
Using angle sum property, we get
[tex]\angle A+\angle B+\angle C=180^\circ[/tex]
[tex]81^\circ+\angle B+36.86^\circ=180^\circ[/tex]
[tex] \angle B =180^\circ-81^\circ-36.86^\circ [/tex]
[tex] \angle B =62.14^\circ [/tex]
Now,
[tex]\dfrac{\sin A}{a}=\dfrac{\sin B}{b}[/tex]
[tex]\dfrac{\sin (81^\circ)}{13.50}=\dfrac{\sin (62.14^\circ)}{b}[/tex]
[tex]b=\dfrac{13.50\times \sin (62.14^\circ)}{\sin (81^\circ)}[/tex]
[tex]b\approx 12.08[/tex]
Therefore, the length of AC is 12.08 cm.
