Answer:-4

Step-by-step explanation:

it bc the line crosses on -4

Answer:

Neither, if they are parallel they slope would be the same, and if they were perpendicular one of the slopes would be -1/5 so I am pretty sure it is neither. (I also graphed it and it didn't look perpendicular or parallel)

The required work done is 38.82 joules.

Work done to be determine for force of 10 newton on angle of 75° for 15 meters.

Work done is define as the force required to move an object by some displacement.

Here, work done = force x displacement x cosФ
                          =  10 x 15 x cos75°
                          =   150 x 0.25

                           = 38.82 joules

Thus, the required work done is 38.82 joules.

Answer:

∠c=90°, ∠b=47.5°, a=85°

Step-by-step explanation:

∠c is inscribing a semicercle so is half of the intercepted arc and the whole circle is 360 , half will be 180 and the angle will be 90°

∠b is inscribing a 95°arc so is half of that 95/2=47.5°

arc a is part of a semicircle so is 180-95 =85°

Given :

For the school's sports day, a group of students prepared 12 1/2 litres of lemonade. At the end of the day they had 2 5/8 litres left over.

To Find :

How many litres of lemonade were sold.

Solution :

Initial amount of lemonade, I = 12 1/2 = 25/2 litres.

Final amount of lemonade, F = 2 5/8 = 21/8 litres.

Amount of lemonade sold, A = I - F

A = 25/2 - 21/8 litres

A = 9.875 litres

Therefore, 9.875 litres of lemonade were sold.

Hence, this is the required solution.

I believe the answer is -28

Step-by-step explanation

I gotchu bro

The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go

6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given sentence is  Six times a number x is at least −24.

Whenever there is a word times means it is a product.

Atleast means greater than or equal to.

Let x be the number in inequality.

Six times a number x is 6x.

Six times a number x is atleast −24.

6x≥-24

6x≥-24 is the required inequality

Divide both sides by 6

x≥-4

Hence, 6x≥-24 is the inequality of sentence Six times a number x is at least −24 and x≥-4 is the solution of inequality.

Answer:

x = -2

Step-by-step explanation:

x+8 = 2x +10

-2x + x = 10-8

-x = 2

divide both side by -1

answer -- x = -2

Answer:

First number --> x

Second number --> y

x + y = 14 --> x = 14 - y

x - y = 4

so

14 - y - y = 4

14 - 2y = 4

2y = 10

y = 5

so

x = 14 -5

x = 9
