Answer:

commutative - addition

associative - addition

Step-by-step explanation:

commutative is when you can move them in any order and associative can be added in any order.

So you move (x+5) to look like (x+5)+6 (commutative)

then switch parenthesis : x+(5+6) (associative)

then x+11.

Associative means that you can move the parenthesis around the problem and still get the same answer. like (4+2)+3=4+(2+3)
first & sixth are the true

Ax-c=2x+5 solve for x

Dmitriy789 [7]

Ax - c = 2x + 5
ax - c + c = 2x + 5 + c
ax = 2x + 5 + c
ax - 2x = 2x - 2x + 5 + c

ax - 2x = c + 5
X(a - 2) = c + 5
X(a - 2)/(a - 2) = c+5/(a-2)

X = c+5/a-2

I believe this would be the solution.

Someone help please!!!!

LUCKY_DIMON [66]

Answer:

x = -2

TU = 4

UB = 2

Step-by-step explanation:

you can add x^2 with 4x+10 and equate it to 6:

x^2 + 4x + 10 = 6

x^2 + 4x + 4

then u can use the roots formula : x = (-b ± √ (b2 - 4ac) )/2a

so it'll be x = {-4±[√16 - 4(4)]}/2

x= -2

then u can substitute it and find TU and UB

TU= (-2)^2 = 4

UB= 4(-2)+10 = 2

What is the volume of a hemisphere with a diameter of 3.7 m, rounded to the nearest

lidiya [134]

Answer:

volume of the hemisphere ≈13.3 m³

Step-by-step explanation:

To find the volume of the hemisphere, we will follow the steps below;

volume of a hemisphere = volume of a sphere/2

= $\frac{4}{3}$ πr³ /2

= $\frac{2}{3}$ πr³

from the question given, the diameter is 3.7 m, but diameter = 2×radius

radius = diameter /2 = 3.7/2 =1.85 m

π is a constant = 3.14

volume of a hemisphere = $\frac{2}{3}$ πr³

≈ $\frac{2}{3}$ ×3.14 ×1.85³

≈13.3 m³

Therefore, volume of the hemisphere ≈13.3 m³

Answer:

$M(x,y) = (4.8,4.4)$

Step-by-step explanation:

Given

$P(x_1,y_1) = (6,2)$

$Q(x_2,y_2) = (3,8)$

$m:n = PM:MQ = 3 : 2$

Required

Determine the coordinates of M

To solve this, we make use of the following partition formula:

$M(x,y) = (\frac{nx_2+mx_1}{n+m},\frac{ny_2+my_1}{n+m})$

Substitute values for m, n, x's and y's

$M(x,y) = (\frac{2*3+3*6}{2+3},\frac{2*8+3*2}{2+3})$

$M(x,y) = (\frac{24}{5},\frac{22}{5})$

$M(x,y) = (4.8,4.4)$

<em>Option D is correct</em>
