Mason wrote the expression shown below 5(y+2). Write an expression that is equivalent to Mason’s expression
rusak2 [61]

Answer:

5y+10

Step-by-step explanation:

The best way to rewrite this equation is to use the distributive property.

5y+10

Or, we can just use the commutative property to switch the numbers around, but I recommend the distributive.

5(2+y)

Hope this helps!

After spending $3750 for tables and $3650 for chairs a convention center manager finds that the furniture cost 6% more than last
pshichka [43]

Answer:

$6981

Step-by-step explanation:

Let's find the answer by using the following formula:

(this year cost)=(last year cost)+((last year cost)*(percent increase of cost)) so:

3750+3650=X+0.06X where X=last year cost, then:

7400=1.06X

6981.13=X

In conclusion, last year he spent $6981.

A point M on a segment with endpoints X(1, −2) and Y(10, 3) partitions the segment in a 4:1 ratio. Find M. You must show all wor
kow [346]

Answer:

(8.2,2)

Step-by-step explanation:

1.

4:1 ratio means XY divided into 5 equal sections. (5 = 4+1)

4:1 ratio means (4/(4+1))

4:1 ratio means (4/5)

2.

4:1 ratio means M is 4/5 of the way from the initial point X(1, −2)

3.

get the x and y distances between (1, −2) and  (10, 3)

x2-x1=9

y2-y1=5

4.

since  initial point is (1, −2)

you add 1 to the new x value and

you add -2 to the new y value

ANSWERS:

x-coordinate of M = 1 + (4/5)(9) = 1 + 7.2 = 8.2

y-coordinate of M = -2 + (4/5)(5) = -2 + 4 = 2

As we move along XY from X to Y,

x increases by 9 and

y increases by 5

M is the point on XY that is 4/5 of the way from X to Y.

M is 4/5 of the distance from (1,-2) to (10,3).

To find M x and y coordinates 4/5 of distance between (x1,y1) and (x2,y2):

To find M x and y coordinates 4/5 of distance between (1,-2) and (10,3):

x-coordinate of M = 1 + (4/5)(9) = 1 + 7.2 = 8.2

y-coordinate of M = -2 + (4/5)(5) = -2 + 4 = 2

√-225 • √-36 . show work.
Darya [45]

Answer:

±90

Step-by-step explanation:

√(-225) · √(-36) = (15i)·(6i) = 90i² = 90·(-1) = -90

_____

On the other hand, ...

... √(-225) · √(-36) = √((-225)·(-36)) = √8100 = 90

___

If you consider all the roots at each stage, the result is ±90. Since you're working with complex numbers here, it is reasonable to recognize every number has two square roots.

... √(-225) = ±15i

... √(-36) = ±6i

... √(-225) · √(-36) = (±15i)·(±6i) = ±90i² = ±90
