Answer:

-2.2y - 1.8

Step-by-step explanation:

We are to simplify the expression:

1.2y + 4.5 - 3.4y - 6.3

Collect like terms:

1.2y - 3.4y + 4.5 - 6.3

Simplify:

-2.2y - 1.8

That is the answer.

For what values of K does x2+kx+9=0

Airida [17]

Answer:

$k = 6$

Step-by-step explanation:

$x {}^{2} + kx + 9 = 0$

here,

a = 1,

b = k

c = 9

now,

$D = b {}^{2} - 4ac$

$k {}^{2} - 4(1)(9) = 0 \\ k {}^{2} - 36 = 0 \\ k {}^{2} = 36 \\ k = 6$

Question 4 of 5

Arturiano [62]

Answer:

D. 9 cm

Step-by-step explanation:

The radius of the sphere can be found by solving the volume equation for the radius.

V = 4/3πr³

3V/(4π) = r³

r = ∛(3V/(4π)) = ∛(3×3052/(4×π)) ≈ ∛728.611

r ≈ 9.0 cm

The radius of the sphere is about 9 cm.
