Answer:
3
Step-by-step explanation:
It is a well known trick that when you add together the digits of a number, if they are a multiple of 3 then the number is divisible by 3. Let's go through the options and check them:
7+5+7+0=19 not a multiple of 3
7+5+7+1=20 not a multiple of 3
7+5+7+2=21 multiple of 3
7+5+7+3=22 not a multiple of 3
7+5+7+4=23 not a multiple of 3
7+5+7+5=24 multiple of 3
7+5+7+6=25 not a multiple of 3
7+5+7+7=26 not a multiple of 3
7+5+7+8=27 multiple of 3
7+5+7+9=28 not a multiple of 3
As you can see, only 3 of these were possibilities that satisified the conditions. Hope this helps!
Answer: c = \frac {d + ab} {a}
Step-by-step explanation:
For this case we have the following equation:
a (c - b) = d
We want to solve the equation for the letter c.
To do this, we apply the distributive property:
ac-ab = d
Then, applying addition property of equality we have:
ac = d + ab
Then applying division property of equality we have:
c = \frac {d + ab} {a}
A :
The line should be placed in between 0 & 1 : 4
B : []

Answer:
A.
(x - 5)^2 + (y + 8)^2 = 4
Step-by-step explanation:
The equation for a circle in center radius form is
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
We need to determine the radius, from the two points which is the distance
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (5-5)^2+( -8--6)^2)
= sqrt(0+ (-8+6)^2)
= sqrt( 0+(-2)^2)
= sqrt(4)
= 2
The radius is 2 and the center is (5,-8)
(x-5)^2 + (y--8)^2 = 2^2
(x-5)^2 + (y+8)^2 = 4
Step-by-step explanation:
Hi, Hope this will help:)
