The coefficient is 7

schepotkina [342]3 years ago

In 1 * 4 + 7y, 7 is the coefficient of y. The coefficient of a variable is a constant (number) that is before the variable and multiplies itself and the variable. Since 7 is the number before y multiplying itself by y, 7 is the coefficient of y.

Can anyone please help me?

Answer:

B. x =1 , y = -5

Step-by-step explanation:

So, what we can do is to simply plug in all of the equations and see which one fits. Equation: x - y = 6

A. x =1 , y = -6

1 -(-6) = 6

1 + 6 = 7

A would be incorrect.

B. x = 1, y = -5

1 - (-5) = 6

1 + 5 = 6

Therefore, B would be correct.

Lemur [1.5K]

Answer:

Value of h greater than 5.4 will make inequality false.

Step-by-step explanation:

This question is incomplete; here is the complete question.

The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel 750 ≥ 75 + 125h. What value of h does NOT make the inequality true?

From the given question,

Per night expense (expected) = $125

If Jones family stays in the hotel for 'h' days then total expenditure on stay = $125h

Charges for scuba diving = $75

Total charges for stay and scuba diving = $(125h + 75)

Since Jones family has saved $750 for the vacation trip so inequality representing the expenses will be,

125h + 75 ≤ 750

125h ≤ 675

h ≤ \frac{675}{125}

h ≤ 5.4

That means number of days for stay should be less than equal to 5.4

and any value of h greater than 5.4 will make the inequality false.

ILL GIVE BRAINLEST Determine whether the two angles in each figure are complementary, supplementary, or neither
Firdavs [7]

Answer:

Step-by-step explanation:

If the sum of two angles = 180°

Then the pair of angles will be supplementary.

If the sum of two angles = 90°

Then the pair of angles will be complementary.

Sum of angles having measures 98° and 82° = 98° + 82°

                                                                          = 180°

Therefore, both the angles will be supplementary.

Sum of angles having measures 134° and 36° = 134° + 36°

                                                                            = 170°

Therefore, these angles are neither supplementary nor complementary.

So the answer is NEITHER.
