Which line is parallel to the line whose equation is 4x + 3y = 7 and also passes through the point (-5,2) ?
A. 4x + 3y = -26
B. 4x + 3y = -14
C. 3x + 4y = -7
D. 3x + 4y = 14

Answer:

3

Step-by-step explanation:

A ( 2, 2 )

( x1, y1 ) = ( 2, 2 )

Here,

x1 = y1 = 2

B ( - 2, - 2 )

( x2, y2 ) = ( - 2, - 2 )

Here,

x2 = y2 = - 2

Distance formula : -

d = √ ( x2 - x1 )² + ( y2 - y1 )²

AB = √ ( - 2 - 2 )² + ( - 2 - 2 )²

= √ ( - 2 )² + ( - 2 )²

= √ 4 + 4

AB = √8

The value of √8 is 2.828.

Roundoff to nearest 10 is 3.

Answer:

Its a function

Step-by-step explanation:

The ansswer is B

Answer:

a) 251.33 cm

b) 40 times

Step-by-step explanation:

C = d x r

a) C = 80 cm x 3.14 = 251.33 cm

b) 100 m = 10,000 cm

10,000cm/251.33cm = 40 times

Answer:

132 minutes

Step-by-step explanation:

If you see that 1 mile is 22 minutes, then you would know 2 miles is double, three miles is triple and so on. So you would do 22x6 for the six miles to get your answer of 132, or you can even do 22 plus 22 six times.

Answer:

132 minutes = 2 hours and 12 minutes

Step-by-step explanation:

22 x 6 = 132 (minutes)

to find it in hours:

132 divided by 60 = 2.2 (2 hours)

2 x 60 = 120

132 - 120 = 12 (minutes)

Step-by-step explanation:

2 ft / 1 second

and now

x/10 foot / 1/4 second

we need to multiply the original ratio by 1/4 to get the same denominator :

2/1 × (1/4)/(1/4) = (2/4) / (1/4) = (1/2) / (1/4)

how many 10th foot are 1/2 ?

we need to bring 1/2 to the denominator of 10.

1/2 = x/10

10 = 2x

x = 5

so, 1/2 = 5/10

therefore, or answer is

5/10 foot / 1/4 second

Answer:

5.3 of both lengths, if the lengths are the same

Step-by-step explanation:

28 squared equals 5.29... which rounds up to 5.3 if you're trying to find a number rounded up to the tenths. I also tried with 5.2 and 5.4, but they weren't in btw. 28 and 29, so the answer must be 5.3

Answer: The answer is 17.4

Answer:

single egg

Step-by-step explanation:

0.20 x 12 = 2.40

regular = 2.50

Answer:

one egg a time

Step-by-step explanation:

We know a dozen eggs consists of 6eggs and in total it costs $2.50

Now 1 egg is $0.20 when you buy 5 more eggs separately it gives you a total amount of $1.25 so you save more money when you buy one egg at a time

Answer:

It is called a negative number. For example, -4   -976   -23   -21

Answer:

x= 6

Step-by-step explanation:

12+3x=30

3x+12=30

3x+12-12=30-12

3x=30-12

3x=18

3x divided by 3 = 18 divided by 3

x=18 over 3

18 divided by 3 is 6

x=6

Answer:

x = 6

Step-by-step explanation:

12 +3x = 30

Subtract 12 from both sides

3x = 30 - 12

3x = 18

Divide both side by 3

x = 18/3

x = 6

3)-3(v + 25) = 111

Use distributive property

-3v + (-3)*25 = 111

-3v - 75 = 111

Add 75 to both sides

-3v = 111+ 75

-3v = 186

Divide both sides by (-3)

v = 186/(-3)

v = -62

Answer:

(-2,-4)

Step-by-step explanation:

Graph it and you would find that (-2,2) is 3 units higher than the line y=-1. So you would reflect it across by starting at (-2,-1) and count downwards, 3 to get (-2,-4).

Answer:

  (b)  2y ≤ 25x and y ≥ 245

Step-by-step explanation:

You want the teacher/student ratio to be at least 2/25, so ...

  x/y ≥ 2/25

  25x ≥ 2y . . . . . multiply by 25y

  2y ≤ 25x . . . . . swap sides to get the form used in answer choice B

The other inequality says the number of students is at least 245:

  y ≥ 245

Answer:

B- 2y ≤ 25x and y ≥ 245

Step-by-step explanation:

2(7x +8)=12

2(7x +8)/2 =12/2

7x +8 =6

7x=6-8

7x = -2

x= -2/7

Hi there! :)

12=2(7x+8)

Use the Distributive property:

12=14x+16

Move all the numbers to the right side and the variables to the left side:

-14x=16-12

-14x=4

Divide both sides by -14 to isolate x:

x=[tex]-\frac{4}{14} \\-\frac{2}{7}[/tex]

⇛ 1/2

LHS ≠ RHS

a÷b ≠ b÷a

⟨ii⟩

LHS = (a÷b)÷c

⇛ (-20÷-10)÷5

⇛ 2÷5

⇛ 2/5

RHS = a÷(b÷c)

⇛ -20÷(-10÷5)

⇛ -20÷-2

⇛ -20/-2
