Answer:

10 > -6x

Step-by-step explanation:

1/2(-2 x -10) > 3(4 - 6)

PEMDAS

do the work in the parentheses:

1/2(20) > 3(-2)

multiply (you multiply when a number is next to parentheses fyi):

1/2 x 20 = 10, 3 x -2 = -6

answer: 10 > -6x

Answer:

x>1

Step-by-step explanation:

\frac{1}{2} × (-2x - 10) > 3(4-6x)

-2x - 10 > 6(4-6x)

-2x - 10 > 24 - 36x

-2x + 36x > 24 + 10

34x > 34

x>1

A rectangular metal plate is measured to be 7.6cm long and 3.1cm wide, both correct to one decimal place.
ElenaW [278]

Answer:

We know that the rectangular plate has measures of:

length = 7.6 ± 0.05 cm

width = 3.1 ± 0.05 cm

(the error is 0.05cm because we know that both measures are correct to one decimal place)

First, the upper bound of the length is equal to the measure of the length plus the error, this is:

L = 7.6 cm + 0.05 cm = 7.65 cm

The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.

Remember that the area for a rectangle of length L and width W, is:

A = W*L

Then the upper bound of the area is:

A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2

Answer:

Answer:

y = -5(x - 7)^3 - 1

Step-by-step explanation:

You kind of just plug in the numbers.

a vertical stretch by a factor of ​5: y = 5x^3

a reflection across the​ x-axis: y = -5x^3

a vertical translation 1 unit down: -5x^3 - 1

a horizontal translation 7 units right: -5(x - 7)^3 -1

If the dimensions of a square based pyramid are tripled what happens to the volume?
11Alexandr11 [23.1K]
Plug in numbers. if originally, it was V=1/2 * 1 * 1 * 2=1 

<span>tripling the dimensions would be V=1/2 * 3 * 3 * 6=27 </span>

<span>it would be 27 times larger. this could also be found by 3^3, just as doubling would render 2^3
