Answer:
a = -21
Step-by-step explanation:
Multiply the equation by the reciprocal of the coefficient of 'a'.
(-7/6)(-6/7)a = (-7/6)(18)
a = (-7)(18/6) = (-7)(3)
a = -21
Answer:
I think the answer is a=-1/21

when rounding off numbers to specific decimal places look at the number after that place. If that number is less than 5 then keep the needed decimal the same. if it is greater than 5 then round up by one.
Examples:
15.69 ⇒ 15.7
15.64 ⇒ 15.6
17.890 ⇒ 17.89
17.898 ⇒ 17.90

Answer:
B
Step-by-step explanation:
Start by using the distance formula to find the raidus
The two points are (-2,1) and (-4,1)
√((-4+2)²+(1-1)²)= 2
The radius is two and we have our center which means we can write
(x+2)²+(y-1)²=4
now it's just a matter of expanding everyhting
x²+4x+4+y²-2y-3=0
x²+y²+4x-2y+1=0
This is equal to B

Greetings from Brasil...
G = {4; 8; 12; 16; 20; 24; 28; 32; 36; 40; 44; 48; 52; 56; 60; 64; 68; 72; 76; 80; 84; 88; 92; 96; 100; 104; ...}
F = {1; 4; 9; 16; 25; 36; 49; 64; 81; 100; ...}
So, according to the statement, it is desired:
G ∩ F - the intersection between the 2 sets, that is, which numbers are present simultaneously in the 2 sets....
Looking at the sets we conclude that
G ∩ F = {4; 16; 36; 64; 100}
OBS: note that in truth G are the multiples of 4
Final answer:
The first five elements of set H, which include positive integers divisible by 4 that are also perfect squares, are 4, 16, 36, 64, and 100.
Explanation:
The two sets mentioned in the problem are Set G, which contains positive integers divisible by 4, and Set F, which contains perfect squares. The intersection of these two sets is Set H. To find the elements of Set H, we look for numbers that are both divisible by 4 and perfect squares. The first five such numbers are 4, 16, 36, 64, and 100. For example, 16 is both a multiple of 4 and a perfect square because it can be expressed as 4*4 and is the square of 4. Similarly, 36 fits both criteria because it can be expressed as 4*9 and is the square of 6. We continue this pattern to identify the first five elements of Set H.
