Answer:
30x +25y = 148
Step-by-step explanation:
We can use substitution to find the point of intersection of ...
Using the second equation, we can write an expression for y:
y = 6 -x
Substituting that into the first equation gives ...
3x +14 = 2(6 -x)
3x +14 = 12 -2x . . . . . eliminate parentheses
5x = -2 . . . . . . . . . . . add 2x-14
x = -0.4 . . . . . . . . . divide by 5
y = 6 -(-0.4) = 6.4
__
Now, we want an equation for a line through the point (-0.4, 6.4) that is perpendicular to 5x = 6y+1
The perpendicular line will have the coefficients swapped with one of them negated. The constant will accommodate the given point.
6x = -5y + c
6(-0.4) +5(6.4) = c = 29.6
The perpendicular line can be written ...
6x = -5y +29.6
In standard form, the equation is ...
30x +25y = 148
Answer:
1. chord 2. di 3. si 4. chromatic scale 5. I don’t know, maybe chromatic scale 6. I don’t know but c sharp is the same as d flat if that helps at all
Answer:
So the answer should be 1/4.
Step-by-step explanation:
so a cube has all equal sides and volume is equal to s^3 or side*side*side in this case 1/2*1/2*1/2. There are two cubes so you would multiply that by two creating 2*1/2*1/2*1/2
Hope this helps :)
Please tell me if not.
The number is 10.
x/5 = x-8
You multiply both sides by 5.
x = 5(x-8)
x = 5x-40
Subtract 5x from both sides
-4x = -40
x= -40 / -4
x=10
Answer:
5/22
Step-by-step explanation:
A bag has 6 blue marbles, 4 red marbles, and 2 green marbles. Wo marbles are randomly chosen without replacement.
Total number of marbles =
6 blue marbles + 4 red marbles + 2 green marbles
= 12 marbles
The probability of picking a blue marble = P(B) = 6/12
Therefore, the probablilty that both marbles picked are blue without replacement is
= 6/12 × 5/11
= 30/132
= 5/22
