Solve: 5x=-6x+9
A: x= -9
B: x= -9/11
C: x= 9
D: x= 9/11
Answer:
x = 9/11
Step-by-step explanation:
5x = -6x + 9
Add 6x to both sides
11x = 9
Divide both sides by 11
x = 9/11
Answer:
X Equals 9/11
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable. So X will equal 9/11, which in decimal form is 0.81.

7
Step-by-step explanation:
This is easy. You simply see what 2 1/3 is of 3. The answer is 7.
Please make brainliest!
Answer:
[tex]5 \frac{7}{50}[/tex]
Step-by-step explanation:
we can write the following ratios
laps:time
2.333:4.3333
3:x
To solve this just multiply 4.333 by 1.28571428571 (this is what we mulitplied 2.333 by to get 3)
do this and round to get 5.14 minutes
let's convert this into a fraction just in case
5.14= 514/100 = 257/50 = 5 7/50

4x + 5 + 3x – 12 =
A.9x-9
B.7x+7
C.7x-7
Answer:
7x - 7
Step-by-step explanation:
In this equation you are going to add like terms.
The like terms you have are the terms with x and then the terms without the x.
So 4x + 3x = 7x
5 - 12 = -7
So your answer is 7x-7

Name this polynomial by its degree: 3x² + 5x-3
Answer:
[tex]\boxed{\textsf {The given polynomial is a quadratic polynomial. }}[/tex]
Step-by-step explanation:
A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .
[tex]\sf\implies p(x)= 3x^2+5x-3 [/tex]
So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .
★ More to Know :-
When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.
That is ,
[tex]\sf\implies p(x)= 3x^2+5x-3=0[/tex]
This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .

Part 1) Finding the inverse
Let x = r and y = H(r)
We have the equation y = 6240(1 + x/100)^t which is the same as saying y = 6240(1 + 0.01x)^t since 1/100 = 0.01
From here, swap x and y to get the equation x = 6240(1+0.01y)^t
Let's solve for y
x = 6240(1+0.01y)^t
6240(1+0.01y)^t = x
(1+0.01y)^t = x/6240
1+0.01y = (x/6240)^(1/t)
0.01y = (x/6240)^(1/t)-1
100*0.01y = 100*((x/6240)^(1/t)-1)
y = 100*((x/6240)^(1/t)-1)
y = 100*(x/6240)^(1/t) - 100
This becomes r = 100*(H/6240)^(1/t) - 100 after we replace y with r and x with H. Note the r and H swapped places, just like x and y did. Earlier we had H isolated on the left, but now r is isolated on the left.
We could write r(H) = 100*(H/6240)^(1/t) - 100 to mean the same thing.
So what exactly does this inverse function do? Well the original function tells us the number of households for any given growth rate, which is r.
The inverse function swaps things around to allow us to find the growth rate if we know how many households there are. We're working backwards. In both cases, t is held to some constant fixed value.
===========================================================
Part 2) Finding the growth rate if the number of households is 7800 after 3 years.
We're going to plug in H = 7800 and t = 3 into the inverse function we found to determine the value of r, or r(H)
r(H) = 100*(H/6240)^(1/t) - 100
r(7800) = 100*(7800/6240)^(1/3) - 100
r(7800) = 7.72173450159419
You'll need your calculator to get this approximate value. After rounding to two decimal places, we get r(7800) = 7.72
Since r = 7.72, this means the growth rate is 7.72%

Solve for x.
18+x=y
x = 0
?
Answer:
The answer is 18
Step-by-step explanation:
18 + x really means 18 + 0, because x is equal to 0
and if 18 + x = y, it means 18 + 0 = y,
so y is equal to 18

5/7x - 14 = -22. Find x.
Answer:
x = -56/5, -11 1/5, or -11.2
Step-by-step explanation:
5/7x - 14 = -22
5x -98 = -154
5x = -154 + 98
5x = -56
x = -56/5, -11 1/5, or -11.2
Answer:
x= -11.2
Step-by-step explanation:
5/7x-14=-22
+14 +14 Add 14 on both sides
5/7x = -8
(7/5)*5/7x = -8*(7/5) Multiply by the reciprocal on both sides to leave x alone
x= -11.2 Answer

What is the standard form equation for a 1/2 line that passes though (-3,-3) and (4,2)
Answer:
y= 5/7x -2.7
Step-by-step explanation:
Y= mx + c (-3,-3) (4,2)
x1 , y1 x2, y2
to find m (gradient)
y^2 - y^1 / x^2 - x^1
2-(-3) / 4 - (-3)
5/7 m = 5/7
take (4,2) and gradient and substitute
2=5/7(4) + c
2=4.7+ c
2-4.7 = c
-2.7 = c
now we have c and m so just put it in the equation
y= 5/7x -2.7
Find the product. (2f – 1)^2 =
Answer: 4f^2 -4f+1
Step-by-step explanation:
2f-1)^2
This is equal to
(2f-1) * (2f-1)
FOIL
first: 2f*2f = 4f^2
outer: 2f*-1 = -2f
inner: -1*2f = -2f
Last = -1*-1 = 1
Add them together: = 4f^2 -2f-2f+1
Combine like terms 4f^2 -4f+1
Answer:
(2f-1)(2f-1)
2f^2-2f-2f+1
2f^2-4f+1

Answer:
volume = Pi(2x^2+3x-5) x (2x+5)^2 or P1(8x^4+52x^3+100x^2-125)
Step-by-step explanation:
radius = (4x+10)/2 = 2x+5
volume = Pi(2x^2+3x-5) x (2x+5)^2
volume = Pi(2x^2+3x-5) x (4x^2+20x+25)
volume = P1(8x^4+52x^3+100x^2-125)
