Y (y + 2) = y2 - 6<br> also<br> 2 [x - (1-3x)] = 3 (x + 1)

vladimir1956 [14]

Answer:

Step-by-step explanation:

y(y+2)=y²-6

y²+2y=y²-6

2y=-6

y=-3

2[x-(1-3x)]=3(x+1)

2[x-1+3x]=3x+3

2(4x-1)=3x+3

8x-2=3x+3

8x-3x=3+2

Determine if x+3 is a factor of -3x^3+6x^2+6x+9. How do u know

krek1111 [17]

By the factor theorem, if x + 3 is a factor of f(x) = -3x^3 + 6x^2 + 6x + 9, then f(-3) = 0
f(-3) = -3(-3)^3 + 6(-3)^2 + 6(-3) + 9 = -3(-27) + 6(9) - 18 + 9 = 81 + 54 - 9 = 126.

Therefore, x + 3 is not a factor of the given function

Ratio, Rate, and Speed

Andre45 [30]

Answer:

10:12:15

Step-by-step explanation:

a/b=5/6

b/c=4/5

thus

c/b=5/4

LCM of 4 and 6=12

5/6=10/12

5/4=15/12

b is the 12 in both

thus ratio between a:b:c is 10:12:15

i can reply in comments if more explanation is needed

√70 is between which two numbers on the number line?

Leto [7]

Answer:

C) 8 and 9

Step-by-step explanation:

We know that 70 is between two perfect squares.

The square numbers 64 and 81 can help us solve this question.

64<70<81

We take square root to get:

$\sqrt{64} \: < \: \sqrt{70} < \sqrt{81}$

We simplify this to get:

$8 \: < \: \sqrt{70} \: < \: 9$

Therefore √70 is between 8 and 9.

The correct option is C.
