2(-2y-4)-3y=13
-4y-8-3y=13
-7y=21
y=-3
x=2
substitute three into one of the original two problems and you get 2!
Hope this helped
The circle is in A, so (-1, 4) coords
(x - xo)² + (y - yo)² = r²
(x - (-1))² + (y - 4)² = r²
(x + 1)² + (y - 4)² = r²
And the radius is the length of segment AC
distance of AC is
So r = 5
(x + 1)² + (y - 4)² = 5²
(x + 1)² + (y - 4)² = 25
Answer:
z + 7
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
The sum of z and 7
<em>z + 7</em>
<em />
Answer: z + 7
<u>If needed solve:</u>
z + 7 - 7 = 0 - 7
<em>z = -7</em>
Answer:
332=y
Step-by-step explanation:
It must be B.
There are two possibilities; in the first, the first digit is below 5, in the second, it is above. The probability of the first possibility is 3/8, because there are 3 possible digits below 5 and 8 total digits. In this scenario, the chance of the second digit being below 5 is 2/7, because one of the digits is taken. In the other possibility, which has a chance of 5/8, the probability of choosing a number below 5 is 3/7, since all of them are still available. Doing the arithmetic, you find that the total probability is 2/7. Hope this helps!
