Find the slope of line:6x+3y=21

Answers

Answer 1

Answer:

-2

Step-by-step explanation:

6x+3y=21

Bring the equation to y=mx+c form

3y=21-6x

y=-2x+7

When comparing, m=-2

Slope m=-2

Answer 2
first, subtract 6x from both sides: 3y= -6x+21
next, divide everything by three: y= -2x + 7, the slope would then be -2 & the y-intercept would be 7

Two men can do a work in 4 days and 6 days respectively how many days will it take if they work togatherpls tell with steps ill mark brainlist

Answers

Answer:

The answer is 12/5 days

Step-by-step explanation:

The First Man (FM) takes 4 days to complete the work

In one day he does (1/4)th portion of the work

The Second Man (SM) takes 6 days to complete the work

In one day he does (1/6)th portion of the work

The FM and SM together do [ (1/4 ) + ( 1/6) ] th portion of the work

So , [ (3+2 )/12] = ( 5 / 12 ) = 5/12 th portion in one day

Hence, FM and SM together complete the work in 12/5 = 2.4 days

Answers

Answer:

B.

Step-by-step explanation:

When you move right or left it's inside the parentheses and the opposite so right is - and left is + when you move up or down its the same so up is + and down is -.

Answer:

B

Step-by-step explanation:

It's asking for moving right 3 and down 2. To move right three, you have to subtract 3 (It's switched up). This goes inside the parenthesis, because if it was outside of the parenthesis, it would be going up or down. Now, to go down 2, you have to subtract 2 outside of the parenthesis (It's normal). That leaves you with f(x-3)-2. Therefore, the answer is B.

Suzy went to a department store and brought 3 pairs of shoes. The first pair of shoes were not too expensive, but the second pair was twice as much as the first pair. The third pair of shoes were $5 more than the first pair. She paid with a $100 bill and got $3 in change. How much did each pair of shoes cost?

Answers

Answer:

Cost of first pair shoe = a = $23

Cost of second pair shoe = b = $46

Cost of third pair shoe = c = $28

Step-by-step explanation:

Let

Cost of first pair shoe = a

Cost of second pair shoe = b

Cost of third pair shoe = c

The first pair of shoes were not too expensive, but the second pair was twice as much as the first pair.

b = 2a......... Equation 1

The third pair of shoes were $5 more than the first pair.

c = a + 5...... Equation 2

She paid with a $100 bill and got $3 in change.

a + b + c = $100 - $3

a + b + c = 97........... Equation 3

Substitute 2a for b and a + 5 for c in Equation 3

a + 2a + a + 5 = 97

4a = 97 - 5

4a = 92

a = 92/4

a =$23

The cost of the first pair of shoe = $23

b = 2a......... Equation 1

b = 2($23)

b = $46

The cost of the second pair of shoe = $46

c = a + 5...... Equation 2

c = $23 +$5

c = $28

The cost of the third pair of shoe = $28

Product of two sets a x b;

Solution:

Set A =  (2 3 8)

Name The Angle Pair And Find The Missing Value.

Answers

Answer:

Angle 1 and angle 2

x=9

Step-by-step explanation:

The angle pair is complementary since it makes a right angle, so you could technically name it anything like angle 1 and angle 2. You make the equation 4x+8+5x+1=90. Then, you combine like terms and get 9x+9=90. Then, subtract the 9 from 90, 81. 9x=81. Then, divide the 9 from 81. X=9.

Question 6

are similar
61
101
a
26 ft
30 ft
b
С
45 ft
27 ft
d

Answers

Answer:

Option (D)

Step-by-step explanation:

From the figure attached,

Since, ΔABD and ΔECD are the similar triangles,

Their corresponding sides will be proportional.

[tex]\frac{AB}{EC}=\frac{BD}{CD}[/tex]

[tex]\frac{h}{6}=\frac{(x+10)}{10}[/tex]

10h = 6(x + 10)

Since, the person is standing 35 feet from a street light,

x = 35 feet

By substituting the value of x in the equation,

10h = 6(35 + 10)

10h = 270

h = 27 ft

Therefore, height of the street light will be 27 feet.

Option (D) is the answer.

If the m∠A is less than 90°, then ∠A is an acute angle. M∠A=75° . What can you logically conclude using the Law of Detachment? ∠A is acute. ∠A is acute. ∠A is right. ∠A is right. ∠A is obtuse. ∠A is obtuse. Not enough information. Not enough information.

Answers

Answer:

∠A is acute. ∠A is acute.

Step-by-step explanation:

Given that

m∠A is lower than 90°

So, it is an acute angle

And, M∠A=75°

The acute angle is the angle that measures between 0 degrees and 90 degrees on the other case the obtuse angle should be more than 90 degrees till 180 degrees

So as per the law of detachment the first option is correct and the same is to be considered
