Use the graph that shows the solution to f(x)=g(x). f(x)=1+2x/x g(x)=2+x What is the solution to f(x)=g(x)?
The solution if h(x) = g(x) is ±1
Solution to set of functionsGiven the following functions
h(x)=1+2x/x
g(x)=2+x
The solution of the function occur at h(x) = g(x)
If h(x) = g(x), then;
1+2x/x = 2 + x
Cross multiply
1+2x = x(2+x)
1 + 2x = 2x + x^2
Equate the resulting expression to zero to have;
x^2 = 1
x = ±1
Hence the solution if h(x) = g(x) is ±1

A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?
Answer:
y=1/6x-6
Step-by-step explanation:
The first step is to set up the equation. Since the lines are parallel the slopes will be the same.
Note: y=mx+b; m is the slope and b is the y-intercept
Since we know that the slopes are the same all we have to do is plug in (12,0) in the equation to find b (y-intercept),
0=1/6(12)+b
0=6+b
-6=b
Now that we know b all we have to do is put it in the formula y=mx+b
y=1/6x-6.
Answer:
y = (1/6)x - 2
Step-by-step explanation:
"Parallel" means "has the same slope as..." so the slope of the line you want is 1/6.
y = (1/6)x + b where b is the y-intercept (now, find it using the point (12, 0) ).
0 = (1/6)(12) + b
0 = 2 + b
b = -2
The equation is y = (1/6)x - 2

When Janya was in 6th grade, she invested $1000 into an account that earns 15% interest, compounded quarterly. Six years later, she is a senior and she wants to withdraw the interest earned to help with college expenses. She will learn the initial investment of $1,000 in the account. How much will she withdraw?
a. $2,419
b. $1,150
c. $1,000
d. None of the above
The amount she will withdraw is $2,419.44. (option d)
How much will she withdraw?The interest earned in the account is the difference between the amount invested and the future value of the investment.
Interest earned = future value - amount invested
The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate = 15%/4 = 3.75%m = number of compounding= 4N = number of yearsFV = 1000 x (1 + 0.0375)^(6 x 4)
= 1000 x (1.0375^24) = $2,419.44
Interest earned = $2,419.44 - $1000 = $1,419.44

Y=-3x-14
-2x-y=9
Answer:
The value of x is -5 and y is 1
Step-by-step explanation:
Here,
y = -3x - 14
-2x - y = 9
Substitution Method
y = -3x - 14 ...(1)
-2x - y = 9 ...(2)
Now, substitute the value of y = -3x - 14 in equation (2) we get,
-2x - y = 9
-2x - (-3x - 14) = 9
-2x + 3x + 14 = 9
x = 9 - 14
x = -5
Now, put the value of x in equation (1) we get,
y = -3x - 14
y = -3(-5) - 14
y = 15 - 14
y = 1
Thus, The value of x is -5 and y is 1
FOR VERIFICATION ONLY:y = -3x - 14
1 = -3(-5) - 14
1 = 15 - 14
1 = 1
-2x - y = 9
-2(-5) - 1 = 9
10 - 1 = 9
9 = 9
Hence, L.H.S = R.H.S

In a right triangle, a and b are the lengths of the legs and c is the length of the hypotenuse. Of a = 7 miles and b = 3 miles, what is the perimeter? If necessary, round to the nearest tenth.
Answer:
17.6 miles.
Step-by-step explanation:
Use Pythagoreans Theorem to find c.
a^2+b^2=c^2
49 + 9 = c^2
58 =c^2
√58=c
7.6=c
Now add all of your sides together to find the perimeter.
7 + 3 + 7.6 = 17.6 miles.
The perimeter of the triangle is 17.6 units.
What is the Pythagorean theorem?The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.
Using the Pythagorean theorem, we can find the length of the hypotenuse c:
c² = a² + b²
c² = 7² + 3²
c² = 58
c = √58 ≈ 7.6 miles
The perimeter is the sum of the three sides:
Perimeter = a + b + c
Perimeter = 7 + 3 + 7.6
Perimeter ≈ 17.6 miles

At the aquarium, posters of sharks cost $2 and posters of jellyfish cost $6. Mr. Benson spent $64 to buy 12 posters. How many of each type of poster did Mr. Benson buy?
Answer:
8
Step-by-step explanation:
Step 1: Add the cost of the posters together
Shark: 1 = $2
Jellyfish: 1 = $6
2 + 6 = 8
Step 2: Divide the result by the total amount Mr. Benson spent
64 ÷ 8
[tex]= \frac{64}{8}[/tex]

An ice cream Store with 12 different flavors sells 1 and 2 scoop ice cream cones. A boy sitting outside the store Counted 11 people with ice cream cones and a total of 15 scoops of ice cream how many one Scoop cones were sold
Answer:
7 cones of 1 scoop ice cream were sold.
Step-by-step explanation:
A total of 15 scoops were sold .
Let x be the number of 2 scoop ice cream and y be the number of 1 scoop ice cream
Then
15= 2x+ y---- eq. 1
There were 11 cones sold.
and x+ y = 11--- eq.2
11-x= y
15= 2x+ y
Putting value of y from eq.2 in eq. 1
15= 2x + 11-x
15= x+11
15- 11= x
x= 4
There will be 2*4=8 scoops for 4 cones
ie 4 cones of two scoops ice creams will be sold.
11- 4= 7 cones
and 7 scoops for 7 cones

PROMISE TO GIVE BRAINIEST BUT ONLY IF YOU GET IT RIGHT!
Answer:
5.2
Step-by-step explanation:
Formula for any right triangle is a^2 + b^2 = c^2
So plug in the values and you get:
a^2 + 3^2 = 6^2
convert the squared numbers and you get:
a^2 + 9 = 36
subtract 9 from both sides
9 = 36
-9 = -9
you get:
a^2 = 27
we can't have a squared number as our answer, so we find the square root of both.
[tex]\sqrt{a^2 = 27}[/tex]
a^2 cancels out and you get:
a = 5.2 (simplified and rounded to nearest tenth)
Answer:
3√3
Step by step explanation:
36^2- 3^2= 27
√27= 3√3
3√3 = 5.2
