solve for x
(4/9)^√x=(2/3)^39-√x
Answer:
169
Step-by-step explanation:
(4/9)^√x = (2/3)^39-√x
(2/3)^2√x = (2/3)^39-√x
Comparing the bases ,
2√x = 39-√x
3√x = 39
√x = 13
x = 169

y=3x+5
m=3Parallel lines has equal slope .
So equation of parallel line also have slope 3Take the 2nd option
[tex]\\ \sf\longmapsto 6x+2y=12[/tex]
Cut 3[tex]\\ \sf\longmapsto 3x+y=4[/tex]
[tex]\\ \sf\longmapsto y=-3x+4[/tex]
Note the answerTake 3rd option
[tex]\\ \sf\longmapsto -3x+y=8[/tex]
[tex]\\ \sf\longmapsto y=3x+8[/tex]
Take the 1st option
[tex]\\ \sf\longmapsto 3y=9x[/tex]
[tex]\\ \sf\longmapsto y=3x[/tex]
Option C and A is correct
Answer:
C and A
Step-by-step explanation:
Parallel means same slope, which is 3. Just solve for y in each equation, and see if 3 is the slope.
a. 3y = 9x
y = 3x
---
b. 6x + 2y = 12
2y = -6x + 12
y = -3x + 6
---
c. -3x + y = 8
y = 3x + 8
---
d. y = -1/3 x

Answer:
13/20
Step-by-step explanation:
12/20-4/20+5/20=
8/20+5/20=
13/20
Answer:
[tex] \frac{13}{20} [/tex]
Step-by-step explanation:
Before we can do anything with the fractions, we need to find a common denominator.
To do that, we will first divide 10 by 2 to get a denominator of 5, and whatever we do to the bottom we must do to the top as well. So we will also divide 6 by 2 to get 3.
So 6/10 has now been simplified to 3/5.
Next we can subtract 1/5 from 3/5 since they both share a common denominator of 5, now we have 2/5.
Now in order to find the common denominator of 2/5 and 1/4, we will simply cross multiply the two fractions together like so: (2 × 4 = 8 and 5 × 1 = 5), to get 8/20 and 5/20. So now we can add 8 and 5 normally, since they both share a common denominator now. That's how you get 13/20.
Hope it helps :)
I tried to keep it simple for you.

HELP ASAPPPPPPPPPPPPP
Answer:
Answer: A
Step-by-step explanation:
(go to attachment to see explanation)
hope this helped :D
How to solve this? If u can ols sho step by step
for example, the line is y = ax + b (1)
we have the line go through the point ( 0 ; 3 ) so y = 3 (2)
we also have the line go through the point ( 0 ; 5 ) so x = 5 (3)
And look at the picture we also have b= 3 (4)
Put (2)(3)(4) in (1) we gonna have a= -3/5
so the line gonna be y = -3/5x + 3
P/s: if you don't understand, you can try this:
we have the line go through the point ( 0 ; 3 ) so y = 3
we also have the line go through the point ( 0 ; 5 ) so x = 5
so put it in the answer :
+) -3x -5y = 15
when x = 0 => y = -3 but y = 3 so it's wrong
+) y = -3/5x + 3
when x = 0 => y = 3
when y = 0 => x = 5 it's right :))
+) 3x + 5y = 15
when x = 0
when y = 0 => x = 5 it's right :)) but write improperly :'))
+) y = -3/5 ( x - 5 )
when x = 0 => y = 3
when y = 0 => x = 5 it's right :)) but write improperly :'))
so we choose y = -3/5x + 3
ok done. Thank to me :>
what´s the answer to this?
Step-by-step explanation:
it is a linear function, if the increases in y are constant from point (ordered pair of x and y) to point reissue to the increase in x.
the first table (top left) increases x constantly by 1.
but y increases first by 2 and then by 3 and then again by 3.
this is not constant, so it does not follow the pattern of x.
in technical terms : the slope of the function is not the same for every point of the function.
in other words : it is not a straight line all the way.
so, it is not a linear function.
the second table (top right) increases x constantly by 2.
and y increases constantly by 2.
this is constant also in relation to x.
in technical terms : the slope of the function is the same for every point of the function.
in other words : it is a straight line all the way.
so, it is a linear function.
the third table (bottom left) increases x constantly by 1.
but y increases first by 4 and then by 1 and then again by 1.
this is not constant, so it does not follow the pattern of x.
in technical terms : the slope of the function is not the same for every point of the function.
in other words : it is not a straight line all the way.
so, it is not a linear function.
the fourth table (bottom right) increases x constantly by 2.
but y increases first by 2 and then by 3 and then again by 3.
this is not constant, so it does not follow the pattern of x.
in technical terms : the slope of the function is not the same for every point of the function.
in other words : it is not a straight line all the way.
so, it is not a linear function.
−7a − 12q + 6a + 13q + 4a − 7a
Answer:
-4a + q
Step-by-step explanation:
Group the a-values together and the q-values together and simplify:
-7a + 6a + 4a - 7a - 12q + 13 q
= -4a + q
A satellite’s original velocity is 40000
m/s. After 10 minutes, the velocity of
the satellite is 4000 m/s. What is the
satellite’s acceleration?
Answer:
-60m/s²
Step-by-step explanation:
The first thing to do is know the equation:
(Final velocity - initial (original) velocity) / time (seconds)
Next you check the units:
10 minutes = 600 seconds
Then you use the equation to solve the problem:
(4000 - 40000) = -36000
-36000 / 600 = -60
Units for acceleration = m/s²
Answer = -60m/s²
The value is negative because the satellite's velocity has decreased
Hope this helps.

I’m downloading a 50 gigabyte game at a rate of 5.5 megabytes per second. How many hours would it take to finish installing.
Answer:
It will take 20.2 Hours to finish By the way? What game are you playing???Answer:
2.6 hours to download; installation time is unknown
Step-by-step explanation:
We assume there are 1024 MB in 1 GB, so the time required is ...
time = quantity/rate
time = 50(1024 MB)/(5.5 MB/s) ≈ 9309.1 s
There are 3600 seconds in 1 hour, so this is ...
9309.1 s/(3600 s/h) ≈2.5858... h ≈ 2.6 hours . . . to download
__
This is the time expected for the download. We have no information about the installation time, so we cannot tell you how long it would take to finish installing.

then add this to the above one together,you can eliminate the x, then solve an equation w only y.
after you get y, get it into whatever the above one or below one,you will get the x as well
Answer:
x = 5/6
y = 1 and 3/5
Step-by-step explanation:
12x + 15y = 34
-6x + 5y = 3
12x + 15y = 34
3(-6x + 5y = 3)
12x + 15y = 34
-18x + 15y = 9
30x = 25
30x/30 = 25/30
x = 5/6
-6x + 5y = 3
-6(5/6) + 5y = 3
-5 + 5y = 3
+5 +5
5y = 8
5y/5 = 8/5
y = 1 3/5

a+1, 2a-1 ,a+7 and 3a+4 are in ascending order. if the median is 17. find the value of a.
Since we have an even amount of numbers here, the median is going to be the average of the two middle values, in this case:
(2a-1+a+7)/2 = 17
(3a +6)/2 = 17
3a + 6 = 34
3a = 28
a = 9[tex]\frac{1}{3}[/tex]
Write an explicit formula for the recursive formula
A(n) = A(n - 1) + 3; A(1) = 6
Answer:
[tex]a_{n}[/tex] = 3n + 3
Step-by-step explanation:
The sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
From the recursive formula
a₁ = 6 and d = 3 [ the constant being added to A(n - 1) ] , then
[tex]a_{n}[/tex] = 6 + 3(n - 1) = 6 + 3n - 3 = 3n + 3

i need help...Which table represents a function?
A 2-column table with 4 rows. The first column is labeled x with entries negative 3, 0, negative 2, 8. The second column is labeled y with entries negative 1, 0, negative 1, 1.
A 2-column table with 4 rows. The first column is labeled x with entries negative 5, 0, negative 5, 6. The second column is labeled y with entries negative 5, 0, 5, negative 6.
A 2-column table with 4 rows. The first column is labeled x with entries negative 4, negative 2, negative 2, 0. The second column is labeled y with entries 8, 2, 4, 2.
A 2-column table with 4 rows. The first column is labeled x with entries negative 4, 3, 1, negative 4. The second column is labeled y with entries 2, 5, 3, 0.
Explanation:
A function has each x value map to exactly one y value. Choice A demonstrates this, which is why it's a function. Note how none of the x values are repeated in this table.
Choices B, C and D have repeated x values, which in turn means that we have an x input lead to multiple y outputs. For instance, choice B says that the input x = -5 has the two outputs y = -5 and y = 5; this is sufficient to show that table B is not a function. Choices C and D are a similar story.
