An equation which is parallel to 4x - 6y = -36 passing through points (2, 3) is y = 2x/3 + 5/9.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

In Geometry, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts.

This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Simplifying the equation, we have:

4x - 6y = -36

6y = 4x + 36

Dividing both sides by 6, we have:

y = 2x/3 + 6

m₁ = m₂ = 2/3.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

At point (2, 3), we have:

y - 3 = 2/3(x - 2)

y - 3 = 2/3(x - 2)

y - 3 = 2x/3 - 4/3

y = 2x/3 - 4/3 + 3

y = 2x/3 + 5/9

Statements A and C are correct.

Here, we are given that Arika and Savroop have 19 ½ cups of flour. Arika had a recipe for banana bread that calls for 1 ⅞ cups of flour. Savroop has a recipe that calls for 1 ½ cups of flour.

Let us evaluate each option one by one-

A. Arika's recipe will make 10 whole loaves of banana bread.

Arika's recipe requires 1 ⅞ cups of flour = (8 + 7)/8

= 15/8

Total flour they have = 19 ½ = (19 × 2 + 1)/2

= 39/2

Thus, Arika's recipe will make = 39/2 ÷ 15/8

= 39/2 × 8/15

= 13 × 4/ 5

= 52/5

= 10.4

Thus, the given statement is correct.

B. Savroop's recipe requires 1 ½ cups of flour = (2+ 1)/2

= 3/2

Thus, Savroop's recipe will make = 39/2 ÷ 3/2

= 39/2 × 2/3

= 13

Thus, the given statement is incorrect. Savroop's recipe will make only 13 whole loaves.

C. As we can see above, Arika's recipe will make 10.4 loaves and thus 0.4 cups of flour will be left over. Whereas, in case of Savroop, no flour will be left over. Thus, the given statement is true.

D. By the same reasoning given above, the given statement is false as there will be less flour leftover if Savroop's recipe is used.

E. The given statement is again false as Arika's recipe will make only 10 loaves whereas Savroop's recipe will make 13.

Answer:

$42,857.14

Step-by-step explanation:

12% = 12/100 = 0.12

If the teller's current salary is D and it increases by 12% in one year, the salary next year would be

X(1+0.12) = 1.12X

We know that salary next year is 48000

Using this fact,

1.12X = 48000

Dividing by 1.12 on both sides,

X = 48000/1.12 = 42,857.14

Proportions: A proportion is an equation that can be solved and is made up of two ratios that have been set equal to one another.

When I state that a proportion is the product of two ratios that are equal to one another, I mean that two fractions must also be equal to one another.

Also, the sun doesn't go down for another 4 hours

Answer:

x = 9

m<H = 38 degrees

Step-by-step explanation:

Answer: 9

Step-by-step explanation: sub in 9 for x in 5x-7. we get 38. add 38 and 89 and then subtract that sum from 180, which is 53. now add 53 to 14x+1 and make it equal to 180. To solve for x, subtract 54 from both sides, which gives us 14x=126. Divide both sides by 14 and we get x =9. Now that we know that 9 works for x in both equations, the answer is 9.

Answer:

Step-by-step explanation:

a) this graph is that of a parabola that opens up.  As is the case for all parabolas, the domain is the set of all real numbers.  The range begins with the smallest y-value, which is -4, extending upwards from there:  [-4, infinity)

b) this graph's shape most closely resembles that of a polynomial; as we move from left to right, y increases, reaches a local maximum, decreases to a local minimum, and then continues to increase with x.  As is the case for all polynomials, the domain is the set of all real numbers.  As we move from x = 0 to the left, y decreases without bound; from x ≥ 12 onward, y increases without bound; thus, the range is (-infinity, +infinity).

c) The graph represents a quarter of an ellipse for which x begins at -40 and ends at [4, -16].  Thus, the domain is [-40, 4].  By inspection we see that the smallest y value is -16 and the largest is 4; thus, the range is [-40, 4].

Answer:

y= -3 or just -3

Step-by-step explanation:

The total time they will be driving the second day is 8 hours

The total distance they are planning to go  = 900 miles

Distance travelled on first day = 420 miles

Distance yet to be  travelled on second day = Total distance - distance covered = 900 miles- 420 miles= 480 miles

The speed of the car = 60 miles per hour

60 miles of distance covered in time = 1 hour

1 mile of distance covered in time = 1 hour /60 miles = 1 minute

This is solved using Unitary Method

1 hour = 60 minutes

480 miles can be covered in time = 1 minute × 480 miles

                                                         = 480 minute

                                                         =8 hours

Hence, The total time they will be driving the second day is 8 hours

Distance and displacement are two quantities that appear to mean the same thing but have very different meanings and definitions. Distance is defined as "how much ground an object has covered during its motion," whereas displacement is defined as "how far out of place an object is."
