Find the center and radius of the circle with equation (x + 2)2 + (y + 7)2 = 81.

seropon [69]

The equation of a circle is:

(x - h)² + (y - k)² = radius²
where (h, k) is the center of the circle.

Your center is (- 2, - 7).
Your radius is √81 = 9

Mrs adams buys 4 bananas and 6 apples. Tell wether true or false the ratio of bananas to apples is 6:4

TEA [102]

Answer: The given statement is FALSE.

Step-by-step explanation: Given that Mrs Adams buys 4 bananas and 6 apples.

We are to check whether the following statement is true or false :

" the ratio of bananas to apples is 6 : 4".

The number of bananas, b = 4

and

the number of apples, a = 6.

Therefore, the ratio of number of bananas to number of apples is given by

$b:a\\\\=\dfrac{b}{a}\\\\=\dfrac{4}{6}\\\\=\dfrac{2}{3}\\\\=2:3\neq6:4.$

That is, the ratio of number of bananas to number of apples is 2 : 3.

Thus, the given statement is FALSE.

Belleview High School has 1212 chaperones for 186186 students on a field trip. Which of the following schools has the same ratio

ser-zykov [4K]

12 chaperones to 210 students....12/210 reduces to 2/35

18/300 reduces to 3/50
20/350 reduces to 2/35
8/160 reduces to 1/20
14/260 reduces to 7/130

so the same ratio would be Jefferson High School

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

$m$ - slope

$b$ - y-intercept

$11)\ m=-1,\ b=2\\\\y=-x+2\\\\12)\ m=-\dfrac{3}{2},\ b=3\\\\y=-\dfrac{3}{2}x+3\\\\13)\ m=3,\ y=-2\\\\y=3x-2\\\\14)\ y=\dfrac{3}{4},\ b=1\\\\y=\dfrac{3}{4}x+1\\\\15)\ m=\dfrac{1}{2},\ b=1\\\\y=\dfrac{1}{2}x+1\\\\16)\ m=-\dfrac{2}{5},\ b=0\\\\y=-\dfrac{2}{5}x\\\\17)\ m=-7,\ b=2\\\\y=-7x+2\\\\18)\ m=\dfrac{4}{3},\ b=-4\\\\y=\dfrac{4}{3}x-4$

19) and 20) you have in other your question.
