Answer:

D

Step-by-step explanation:

The equations are

● 4x + 2y = 10 (1)

● 4x - 2y = -10 (2)

● 4x + 2y = 10

Add - 4x to both sides

● 4x + 2y -4x = 10 -4x

● 2y = 10 -4x

Divide both sides by 2

● 2y/2 = (10 - 4x)/2

● y = 5 - 2x

● y = -2x + 5 (1)

● 4x - 2y = -10

Add -4x to both sides

● 4x -2y -4x = -10 - 4x

● -2y = -10 - 4x

Divide both sides by -2

● -2y/-2 = (-10 -4x)/-2

● y = 10 + 2x

● y = 2x + 5 (2)

So the equation are

● y = 2x + 5

● y = -2x + 5

Graph them

The lines intersect at (0,5) but aren't perpendicular

So the answer is d

Find the value of x in each case:
kotykmax [81]

9514 1404 393

Answer:

  x = 14°

Step-by-step explanation:

The triangle's interior angle at C is the supplement of the exterior angle marked 124°.

  C = 180° -124° = 56°

The exterior angle at B is the sum of the remote interior angles:

  6x = 56° +2x

  4x = 56° . . . . . . subtract 2x

  x = 14° . . . . . . . . divide by 4

a pitcher of fruit punch holds 2 gallons if 9 people share the entire pitcher equally how much punch does each person get
katrin2010 [14]
2×9= 18

18÷9= 2

Answer: 2 cups of fruit punch.

----------

Explanation: so, you divide. why do I know this? because it doesn't say "times," (multiplication word) "more than," (addition word) "less than/ left over." (subtraction word) so what your looking for is "equally," and "each."

So, can you do 2÷9? no, you cant. so you have to multiply 2×9 to get the answer. and what's the answer? 18!

so, now, can you divide 18÷9? yes!! why? because you can only divide big numbers like 18. and you can't divide small numbers like 2 or 9. do you get what I'm saying?

so, what's 18÷9? 2!!


I hope this helps! :) if you still don't understand it just please let me know :)

A balloon is released from a height of 10 feet. The balloon climbs an additional 70% of its previous height as each minute passe
Ainat [17]
The initial height of the balloon is 10 feet which then increases by 70% to (10 ×1.7) = 17 feet, then to (17 × 1.7) =28.9 feet, and so fourth if the rate of increase is kept constant. Therefore, forming a geometric sequence such that to get any term in the sequence we use the formula ar∧(n-1), where a is the first term, r is the common ratio, and n is the term in the sequence. In this case a is 10 and r= 1.7 , to get the height in the fourth minute it means n =5 (for the first term there is 0 minutes, such that for 0 minutes n= 1)
Thus, 10 × 1.7 ∧ 4 = 83.521 feet.
Therefore, the answer is 83.521 feet
