Does Someone Know The Answers To Question 12 And 13 ??? GIVING 30 POINTS

Answers

Answer 1

Answer:

Step-by-step explanation:

For 12 if its a parrell line then the slope of the two lines have to be the same. Since the slope is 3/5 then the answer is A because the slope in A is  also 3/5

for 13 if its perpendicular, then the slope has to be the opposite sign and flipped. so for example if its a negative then the slope has to be a positive and if the slope is 1/2 you have to flip it which is 2/1 and 2/1 equals 2.

so in this one if the slope is 3/5 we have to flip it making it 5/3 and the opposite of a positive is a negative so it would be -5/3, so the answer is C.

Answer 2

Answer:

12. A

13. C

Step-by-step explanation:

12. to be parallel needs same slope

13. to be perpendicular flip slope and if positive change to negative

Find the value of x.


Answers

Answer:

x = 19

Step-by-step explanation:

The sum of both angles will be equal to a supplementary angle. A supplementary angle is when two angles add up to be 180°. Write an equation and solve for x.

3x + 5 + 7x - 15 = 180

~Combine like terms

10x - 10 = 180

~Add 10 to both sides

10x = 190

~Divide 10 to both sides

x = 19

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

Given that: 3 groups of 1/8

Then the number 3 and 1/8 is multiplied. Then the expression will be

⇒ 3 × 1/8

⇒ 3 / 8

Then the 3 groups of 1/8 will be 3/8.

Answers

Answer:

Step-by-step explanation:

Given: c(x) = 2x – 6
Find c(x) = 18

Answers

18 = 2x -6 (Subtract 18 on both sides then subtract 2)
-2x = -6 -18
-6 -18 is = -24 (you add negative numbers together)
-2x = -24 (divide both numbers by -2)

X = 12

Answer:

18

X = ---- , y = 12

c

Step-by-step explanation:

Solve for x, y

X = 18

__

c

Y = 12, c ≠ 0

Consider the first equation. Subtract 2y from both sides.

cx - 2y = -6

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

cx = 18, cx - 2y = -6

Pick one of the two equations which is more simple to solve for x by isolating x on the left hand side of the equal sign.

cx = 18

Divide both sides by c.

18

X = __

c

Substitute 18/c for x in the other equation,

c x - 2y = - 6.

18

c x ( ---- ) - 2y = - 6

c

18

Multiply c times ----

c

18 - 2y = - 24

Subtract 18 from both sides of the equation.

- 2y = - 24

Divide both sides by -2.

y = 12

The system is now solved.

X = ---- , y = 12

A factory needs to produce 1,800 jars of peanut butter on a certain day.
They start production at 8:30 A.M. By 10:30 A.M., they have produced 600 jars of peanut butter. At what time will they complete the total number of jars that they need to produce?

Answers

Answer:

2:30 am

Step-by-step explanation:

There is a 2 hour gap in between 8:30 and 10:30 and since they only made 600 jars throughout those 2 hrs you can divide 600 by 2 so you can fins out how many jars they make every hr.

Or you can multiply 600 and 2 to find out how much they make within the next 2 hrs.

600 * 2 = 1200

1200 jars were made at 12:30

1200 * 2 = 1800

1800 jars were made at 2:30

There are two hours between 8:30 A.M. and 10:30 A.M. If they make 600 jars of peanut butter per two hours, then they will make 300 jars per hour. 1800 divided by 6 is 300, so they need six hours to make 1800 jars of peanut butter. So, if they begin production at 8:30 A.M., the factory will have produced 1800 at 4:30 P.M.
