Solve the equation. Check your answer. 27=9x+2-4x
Plz help
The x's are varibles not multiplication btw
Step-by-step explanation:
27=9x+2-4x
or, 27-2=9x-4x
or,25=5x
or,25/5=X
so, X=5
how high is a tree that cast a 23ft shadow at the same time
a 9ft post casts a shadow which is 11ft long
Answer:
tree is about 18.82 ft high
Step-by-step explanation:
The triangles (that are formed by the tree and the poll with their shadows and the line from top to the end of the shadow) are in proportion because they cast the shadow at the same time.
x/9 = 23/11 , we write the proportions
x = 23*9 / 11, multiply both sides by 9
x ≈ 18.82 ft.

(7 - 1) to the 2 power plus 2 and to the 4 power - 8
The answer is 56. work is shown below.
Step 1: apply 2nd power to everything inside parentheses
(7 - 1)² = 7² - 1²
Step 2: apply exponents (remember, exponents are a shorter way to express a number multiplied by itself a number of times).
1 x 1 = 1
7 x 7 = 49
Step 3: subtract
49 - 1 = 48
Step 4: apply exponent
2 x 2 x 2 x 2 = (2 x 2) x (2 x 2)
2 x 2 = 4
2 x 2 = 4
4 x 4 = 16
2⁴ = 16
Step 5: add
48 + 16 = 64
Step 6 (final step): subtract
64 - 8 = 56
final answer: 56

Resuelve las siguientes ecuaciones
a. 3x + 30 = 80 + 2x
Answer:
3x + 30 = 80 + 2x
3x – 2x = 80 –30
x= 50
I hope I helped you^_^
Answer:
x=50
Step-by-step explanation:
3x + 30 = 80 + 2x
subtract 2x from both sides
1x + 30 = 80
subtract 30 from both sides
x=50
Is square root of 11+10 a rational or irrational number
Answer:
Irrational Number is the answer
Answer:
[tex] \sqrt{11 + 10} = \sqrt{22} = 4.69041576 [/tex]
THIS IS IRRATIONAL
Step-by-step explanation:
The correct answer is irrational and the reason for that is the decimals for sqrt of 22 are non-recurring, are non-terminating and lastly it cannot be expressed in a form of a fraction.
I hope this makes sense

The shaded rectangle, which is the correct expression of its perimeter
Answer:
2x + 2y - 4
Step-by-step explanation:
The opposite sides are congruent so perimeter (P) is
P = 2(x + 2) + 2(y - 4)
= 2x + 4 + 2y - 8
= 2x + 2y - 4
[tex]-4\sqrt{28x}[/tex] times [tex]\sqrt{7x^3}[/tex]
Answer:
[tex] {56x}^{2} [/tex]
Step-by-step explanation:
[tex] - 4 \sqrt{28x} \times \sqrt{ {7x}^{3} } [/tex]
[tex] = -4 \times 2 \sqrt{7x} \times \sqrt{7x} [/tex]
[tex] = - 4 \times 2 \times 7x \times x[/tex]
[tex] = {56x}^{2} [/tex]
Choose a linear function for the line represented by the point-slope equation y - 5 = 3(x - 2).
f(x) = 3x - 1
Step-by-step explanation:
[tex]y - 5 = 3(x - 2) \\ y - 5 = 3x - 6 \\ y = 3x - 6 + 5 \\ y = 3x - 1[/tex]
find an equation for the line passing through (4, 1) and perpendicular to the line 2y+4=6x
Answer:
y = 3x - 11
Step-by-step explanation:
2y+4=6x
2y = 6x - 4
y = 3x - 2
y = 3x + b
1 = 3(4) + b
1 = 12 + b
-11 = b
Help me with this question
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The statement of proportionality tells you ...
m = kr³
The values in the fourth column can tell the value of k:
k = m/r³ = 6.75/1.5³ = 2
Then we have ...
m = 2r³
Solving for r gives ...
m/2 = r³
r = ∛(m/2)
These two relations were used to fill in the spaces in the table. (It is convenient to let a spreadsheet do the calculations.)

What is the inverse of f(x) = 2x2 –4?
Answer:
The inverse of the function is
[tex]{ \underline{f {}^{ - 1}(x) = \sqrt{ \frac{x + 4}{2} } }}[/tex]
Step-by-step explanation:
let the inverse of f(x) be m:
[tex]m = {2x}^{2} - 4 [/tex]
take 4 to the left hand side ( changes sign to positive ):
[tex]m + 4 = {2x}^{2} \\ \frac{m + 4}{2} = {x}^{2} [/tex]
take a square root on all sides:
[tex] \sqrt{ \frac{m + 4}{2} } = \sqrt{ {x}^{2} } \\ \\ x = \sqrt{ \frac{m + 4}{2} } [/tex]
substitute x in place of m:
[tex] {f}^{ - 1} (x) = \sqrt{ \frac{x + 4}{2} } [/tex]

Need help fast!!! This question is for algebra 2 and for a Quiz.
Thank youu.
Step-by-step explanation:
it is unclear what is meant by f1 and f2. do you mean f' and f'' ?
I don't think so, as you mentioned algebra 2.
so, is it just a way to identify different functions ? like function 1 vs. function 2 ?
if that's the case, then both functions represent lines.
both lines go through the origin.
but as their slopes are of same size but different sign, one is actually the mirrored version of the other one (mirrored around the x-axis).
FYI - the created visible pattern (4 lines emanating from the origin) would also indicate that the visible pattern (but not the functions) is also mirrored around the y-axis.
find any points of discontinuity for the rational function... y=x-3/x^2-3x-10
Answer:
x = -2 or 5
Step-by-step explanation:
y = (x-3)/((x-5)(x+2))
y is undefined when the denominator is zero.
Assume that an investment of $3000 earns an APR of 6% compounded monthly for 18 months.
How much money is in your account after 18 months?
9514 1404 393
Answer:
$3281.79
Step-by-step explanation:
The compound interest formula is ...
A = P(1 +r/n)^(nt)
where A is the balance resulting from investment of P at annual rate r compounded n times per year for t years.
We have P=$3000, r=0.06, n=12, t=1.5, so the account balance is ...
A = $3000(1 +0.06/12)^(12·1.5) = $3000(1.005^18) ≈ $3281.79
There will be $3281.79 in the account after 18 months.
