Answer:x-5
Step-by-step explanation:
-6(2x+1)=54
Distribute:
-12x-6=54
Add 6 on both sides:
-12x-6+6=54+6
-12x=60
Divide 12 on both sides:
-12x/-12=60/-12
x=-5

Determine whether the inverse of f(x)=2x2−5
is a function. Then find the inverse.
Answer:
Not a function. The inverse is
[tex]y = \sqrt{ \frac{x + 5}{2} } [/tex]
and
[tex]y = - \sqrt{ \frac{x + 5}{2} } [/tex]
Step-by-step explanation:
Any even-degree polynomial functions that are inverted will not be a function.
[tex]f(x) = 2 {x}^{2} - 5[/tex]
Let y = f(x)
[tex] y = 2 {x}^{2} - 5[/tex]
To proceed the inverse, swap the x-term and y-term.
[tex]x = 2 {y}^{2} - 5[/tex]
Convert into function form.
[tex]x + 5 = 2 {y}^{2} \\ 2 {y}^{2} = x + 5 \\ {y}^{2} = \frac{x +5 }{2} [/tex]
The reason why inverted even-degree polynomial function cannot be a function because the inverse graph doesn't pass line test.
Thus the answer is
[tex]y = \sqrt{ \frac{x + 5}{2} } \\ y = - \sqrt{ \frac{x + 5}{2} } [/tex]
which is greater -12/6 or -9/3
Answer: -9/3

what is 9x minus 7= 65 what is x
Answer:
8
Step-by-step explanation:
First, you add the 7 to both sides. Then you divide both sides by 9. This gets you left with x by its self on one side. x = 8
Answer:
x=8
Step-by-step explanation:
x=8 because if you add 65 and 7 you get 72 and when you divide it by 9 you get 8.

Answer:
Solution is invalid
Step-by-step explanation:
Let the time when they will have the same water content be x hours
At x hours;
For the first tank, the content will be;
50 + 10x
For the second;
29 + 3x
Equating both, will give us x
29 + 3x = 50 + 10x
We will get x as a negative number here
Since number of hours can not be negative, the solution is invalid

Step-by-step explanation:
the square root of any negative value results in an imaginary number, 'i'
so, [tex]\sqrt{-3}[/tex] = 3i and [tex]\sqrt{-12}[/tex] is 12i
'i' is equal to -1

3x + 7y = 2 6x-5y=4 solve this by elimination method
Answer:
x=2/3, y=0
Step-by-step explanation:
3x + 7y = 2,
6x - 5y = 4
Make the x coefficient the same in both equations.
3x + 7y = 2
(whole thing multiplied by 2)
6x + 14y = 4
Now subtract the equations to eliminate the x variable.
6x + 14y = 4
-(6x - 5y = 4)
19y = 0
y = 0
Substitute 0 for y in one of the equations.
3x + 7(0) = 2
3x = 2
x = 2/3
Answer:
well your equation has 2 equal signs in it but imma take a guess and say the first one is supposed to be a plus sign so

expand 3a(2b+c) .............
Answer:
We know that the distributive property says this:
a(b+c) = ab + ac
If we apply this to our case, we can put
3a(2b+c) = 3a * 2b + 3a * c
When we multiply numbers and letters, we should multiply both of them:
3a * 2b + 3a * c = 3*2*a*b + 3*a*c = 6ab +3ac
We can use this when we find a number multiplied by a parenthesis..
Answer:
6ab + 3ac
Step-by-step explanation:
3a(2b) + 3a(c)
6ab + 3ac

Find the 13Th term of geometric sequence 1,2,4,
Answer:
a₁₃ = 4096
Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{2}{1}[/tex] = 2 , then
a₁₃ = 1 × [tex]2^{12}[/tex] = 4096

Cindy works in a cake shop and earns $42 per day. She earns an extra $4 for each cake she sells. If Cindy wants to earn at least $50 per day, which inequality shows the minimum number of cakes, n, that she should sell?
42 + 4n ≤ 50, so n ≤ 2
42 + 4n ≥ 50, so n ≥ 4
42 + 4n ≥ 50, so n ≥ 2
42 + 4n ≤ 50, so n ≤ 4
Answer:
Step-by-step explanation:
42+4n<50, so n<4
Answer:
42+4n ≥ 50, so n ≥ 2

So when finding a number in a percent you wanna see how much that percent will go into that number. So like if I said how many times does 60% go into 200 you would have to see how many times the number 200 would go into 60%. does this make sense? If so this is how you can find your answer.
Sorry if I'm wrong I hope you get this right!! Stay beautiful ❤️

Okay, uh... this is gonna be confusing to explain.
So a hexagon's angles add up to 720. This means, we can find each angle's supplementary angle by subtracting each value we know away from the total.
So, we know the inside angle of angle 6 is 90.
So: 720-90=630
Now, typically, you would divide by the remaining angles, but we have basically 2 angles of different values since 1, 2, and 3 are equal, and 4 and 5 are equal.
However, we know that 1, 2, and 3 are 10 degrees less than 4 and 5. So if we "add" 10 degrees to each of those angles we get:
10*3=30
630-30=600
Now we made it as though each angle (1-5) is equal. So now we divide by 5.
600/5=120
This means the supplementary of angles 4 and 5 is 120, so we subtract that value from 180 since a straight angle is 180.
180-120=60
Now, to check this we reverse it.
(120*2)+(120*3)+(10*3)+(90)=
240+360+30+90=
600+30+90=
600+120=
720.

A slow boat to china travels at a constant speed of 17.25 miles per hour for 200 hours. how far was the voyage?
Answer:
3450 miles
Step-by-step explanation:
Multiply the number 17.25 by 200 since the boat is traveling for 200 hours and each hour is 17.25 miles to get 3450 miles which is your answer.
Answer:
[tex]\boxed {\boxed {\sf 3,450 \ miles}}[/tex]
Step-by-step explanation:
Distance can be found by multiply the speed by the time.
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
1. Define Variables
The speed is 17.25 miles per hour and the time is 200 hours.
[tex]s= 17.25 \ mi/hr[/tex]
[tex]t= 200 \ hr[/tex]
2. Calculate Speed
Substitute the values into the formula.
[tex]d=17.25 \ mi/hr * 200 \ hr[/tex]
Multiply. The hours (hr) will cancel each other out and leave miles as the units.
[tex]d=17.25 \ mi *200\\[/tex]
[tex]d=3450 \ mi[/tex]
The voyage was 3,450 miles
