graph the line that passes through the point (0, -3) and is perpendicular to another line whose slope is 2

Answers

Answer:

y = -1/2x -3

Step-by-step explanation:

The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:

y = mx + b

where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...

y = -1/2x -3

Answer:

M = C

BC = LM

B = L

Step-by-step explanation:

We can see that there are double lines between BC and LM, and a triple line curves at Angle B and Angle L.

We can conclude that:

A = K

B = L

C = M

C = K (NO)

BA = MK (NO)

M = C (YES)

BC = LM (YES)

B = L (YES)

Which fraction is close to zero?
a. 5/12 b. 8/12 c. 2/12 d. 4/6

Answers

Answer:

2/12

Step-by-step explanation:

Answer:

C) 2/12

Step-by-step explanation:

You need to convert the fractions to decimals (by dividing the top number by the bottom number).

5/12 = 0.416...

8/12 = 0.666...

2/12 = 0.166...

4/6 = 0.666...

As you can see, 2/12 in decimal form is closer to 0 than the other fractions.

Answer:

36/40 or 90%

Step-by-step explanation:

First convert it to a fraction, which in this case is 36/40.

To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.

36/40 × 100/100

= (36 × 100/40) × 1/100 = 90/100

Therefore, the answer is 90%.

If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.

How many square yards of carpet are needed to cover the floor of a related 15 feet long and 12 feet wide

Answers

Answer:

20 yards squared.

Step-by-step explanation:

First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.

The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.

Solve:
3x-5/2 +x+ 2x-3/3 = 5/6 - 3x/2

Answers

Answer:

x = 26/45

Step-by-step explanation:

Answer:

Given Question

Solve for x :

[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3} = \dfrac{5}{6} - \dfrac{3x}{2} [/tex]

[tex] \green{\large\underline{\sf{Solution-}}}[/tex]

Given expression is

[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3} = \dfrac{5}{6} - \dfrac{3x}{2} [/tex]

On taking LCM of (2 and 3 = 6) on LHS and Taking LCM of ( 2 and 6 = 6) on RHS, we get

[tex]\rm :\longmapsto\:\dfrac{3(3x - 5) + 6x + 2(2x - 3)}{6} = \dfrac{5 - 9x}{6}[/tex]

[tex]\rm :\longmapsto\:9x - 15 + 6x + 4x - 6 = 5 - 9x[/tex]

[tex]\rm :\longmapsto\:(9x + 6x + 4x) - 15 - 6 = 5 - 9x[/tex]

[tex]\rm :\longmapsto\:19x - 21 = 5 - 9x[/tex]

[tex]\rm :\longmapsto\:19x + 9x = 5 + 21[/tex]

[tex]\rm :\longmapsto\:28x = 26[/tex]

[tex]\rm :\longmapsto\:x = \dfrac{26}{28} [/tex]

[tex]\bf\implies \:x = \dfrac{13}{14} [/tex]

VERIFICATION

Consider LHS

[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3}[/tex]

On substituting the value of x, we get

[tex]\rm \: = \: \dfrac{\dfrac{39}{14} - 5}{2} + \dfrac{13}{14} + \dfrac{\dfrac{13}{7} - 3}{3}[/tex]

[tex]\rm \: = \: \dfrac{39- 70}{28} + \dfrac{13}{14} + \dfrac{13 - 21}{21}[/tex]

[tex]\rm \: = \: \dfrac{ - 31}{28} + \dfrac{13}{14} - \dfrac{8}{21}[/tex]

[tex]\rm \: = \: \dfrac{ - 31 + 26}{28} - \dfrac{8}{21}[/tex]

[tex]\rm \: = \: \dfrac{ -5}{28} - \dfrac{8}{21}[/tex]

[tex]\rm \: = \: \dfrac{ -15 - 32}{84}[/tex]

[tex]\rm \: = \: - \: \dfrac{47}{84}[/tex]

Consider RHS

[tex]\rm :\longmapsto\: \dfrac{5}{6} - \dfrac{3x}{2} [/tex]

On substituting the value of x, we get

[tex] \rm \: = \: \dfrac{5}{6} - \dfrac{39}{28} [/tex]

[tex] \rm \: = \: \dfrac{70 - 117}{84}[/tex]

[tex] \rm \: = \: - \dfrac{47}{84}[/tex]

Hence, LHS = RHS

Hence, Verified.

What is the decimal equivalent of 4/5

Answers

Answer:

0.8

Step-by-step explanation:

to find the decimal equivalent we must get the denominator to 100

to do that we must multiply it by 20, 4/5 * 20/20 is 80/100

80/100 is also 80%, which is also 0.80 (which can be simplified to 0.8)
