What is the slope of the line y = 2x + 1 ?

Answers

y = 2x + 1

The slope of the line y is 2.

In the formula: y = mx + b

m is the slope while b is the y-intercept. Since 2 is the number that is in the place of m, it is the slope of the line while 1 is the y-intercept.

y=mx+b

M is the slope, and B is the Y-intercept.

y=2x+b

In this case, 2 is m.

The slope is 2/1, or 2.

If a square had a perimeter of 78.4. What is the length of each side

Answers

We know that all the sides of a square is Equal.
And we also know that a square has 4 sides.
So we take the measurement of the perimeter, which is 78.4 and divide it by 4, which is the number of sides.
to find the length of each side= $(78.4)/(4)$
= 19.6

In conclusion 19.6 units is the length of each side.
Note: if the unit of measurement is given(for e.g: in,m,cm...), we have to include it.
Quick Check: 19.6+19.6+19.6+19.6=78.4

Divide 6/13 by 6/12 .

A. 9/16 B. 1/12 C. 13/12 D. 12/13

Answers

$((6)/(13))/((6)/(12))$

first simplify
$(6)/(12)$ = $(1)/(2)$

$((6)/(13))/((1)/(2))$
make bottom number equal to 1
multiply whole thing by $((2)/(1))/((2)/(1))$
(since 1/2 times 2/1=2/2=1 so bottom number will be equal to 1)

$((6)/(13))/((1)/(2))$ times $((2)/(1))/((2)/(1))$ = $((12)/(13))/((2)/(2))$ = $((12)/(13))/(1)$ = $(12)/(13)$

easy way is
a/b divided by c/d=a/b times d/c
invert and multiply

answer is 12/13

answer is D

Subtract 5x+2x-11 from 3x+^2+8x-7

Answers

A = 3x² + 8x - 7 - (5x² + 2x - 11)
A = 3x² + 8x - 7 - 5x² - 2x + 11
A = 3x² - 5x² + 8x - 2x - 7 + 11
A = - 2x² + 6x + 4

Accumulated depreciation of a particular plant asset refers to: half-yearly depreciation total depreciation. or neither?

Answers

Accumulated depreciation of a particular plant asset refers to neither the half-yearly depreciation nor total depreciation.

Accumulated depreciation is the total depreciation expense reported since the plant asset was bought. Its amount is used to determine the book value or carrying value of the plant asset.

When the plant asset is fully depreciated, that is only the time when accumulated depreciation is equal to the total depreciation.
