Two numbers are 10 units away in different directions from their midpoint, m, on a number line. The product of the numbers is –9

9.
Which equation can be used to find m, the midpoint of the two numbers?

(m – 5)(m + 5) = 99
(m – 10)(m + 10) = 99
m2 – 25 = –99
m2 – 100 = –99

In my opinion the answer is <span>m2 – 100 = –99
proof
</span>m2 – 100 =<span>(m – 10)(m + 10)
for eg. m=1, </span>(-9)(11)= <span>–99</span>

The volumes of a water balloon and an air balloon after they are punctured are represented by the
spin [16.1K]

Answer:

Both air balloon  and water balloon data are best modeled by an  exponential function.  

Step-by-step explanation:

Air balloon

Time (seconds) Volume (cubic centimeters)

0                          95

3                         69  

6                          50

9                          37

12                         27

The relation Volume variation/time is constant for lines, In this case, this value change from point to point, as can be seen next.

(69 - 95)/3 = -8.67

(50 - 69)/3 =  -6.33

(37 - 50)/3 = -4.33

(27 - 37)/3 = -3.33

Water balloon

Time (seconds) Volume (cubic centimeters)

0                           30

3                           15.8

6                           7.8

9                           4

12                          2

(30 - 15.8)/-3 = -4.73

(15.8 - 7.8)/-3 = -2.67

(7.8 - 4)/-3 = -1.27

(4 - 2)/-3 = -0.67

In this case, the relation Volume variation/time also change from point to point.

Then, both air balloon  and water balloon data are best modeled by an  exponential function.

The sum of 7/8 and 4/9 is closer to 0,1,2,or 3?
tresset_1 [31]
2 because you make them with the same denominators that both go into each other EX: 8x9=72 7/8 now equals 63/72 and 4/9 now equals 28/72 now add them together 63/72 + 28/72= 91/72= 1 19/72

Find an equation of the circle that has center (-1, 3) and passes through (1.<br> 1)
pshichka [43]

Answer:

(x + 1)² + (y - 3)² = 8

Step-by-step explanation:

radius (r): √(1 - (-1))² + (1 - 3)² = √8 = 2√2

Formula for circle with center (h,k): (x – h)² + (y – k)² = r²

(x + 1)² + (y - 3)² = 8
