Follow these steps to get your answer!

Divide 36/9 and multiply -6(7)

25 - 5 + 4 - 42

Subtract 25-5

20 + 4 -42

Add 4 to 20.

24-42

Subtract 42 from 24.

-18
Answer 2
Answer:

Answer:

-18

Step-by-step explanation:

start with the figure in brackets. 6(7)=42

then do division. 36/9=4

our expression now is 25-5+4-42

addition first 25+4=29

finish with subtraction. 29-5-42=-18

answer=-18

a technician charges 25$ per hour plus 50$ for a house call to repair home computers. make a table and a graph to show the cost for 1,2,3, and 4 hours of home computer repair service. is there a direct variation?

Answers

Answer:

75$

Step-by-step explanation:

because 25+50=75

Answer:

The graph starts at $75 since the price for call is $50 and 1 hour of work costs $25.

Direct variation is only noticeable at the beginning of the graph after that the function is linear.

What is the length of the hypotenuse of the right angle defined by the points (-3,-1),(1,-1),and (1,2)?A)square root of 3
B)square root of 3
C) 2 timessquare root of 3
D)5

Answers

To find the length of the triangle first find the two coordinates with a common x coordinate, (1,-1) and (1,2). Now find the difference between their y coordinates, -1 and 2. This means that the length of the triangle is 3.
To find the width of the triangle first find the two coordinates with a common y coordinate, (-3,-1) and (1,-1). Now find the difference between their x coordinates, -3 and 1. This means that the width of the triangle is 4. 
By Pythagoras' theorem, we know that hypotenuse = \sqrt{ width^(2) + length^(2) }. Inserting our newfound values into this equation, we an find thelength of the hypotenuse:
hypotenuse = \sqrt{ 4^(2) +3^(2)} hypotenuse = √(16+9) hypotenuse = √(x) 25hypotenuse = 5
Therefore, your answer is D0 5. To visualise this question better, you can plot the points on a graph.

Answers

Answer:

The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"

Step-by-step explanation:

Given values:

2xy =6.....(a)\n\nx-y= 3.....(b)\n\n

After solve equation (a) we get

\ equation: \n\n2xy= 6\n\nxy =(6)/(2) \n\nxy = 3.....(x)\n\n

After solve equation (b) we get

\ equation: \n\nx-y =3\n\nx= 3+y....(x1)\n

put the value of x in to equation (x)

(3+y)y = 3\n

y^2+3y-3=0\n\n\ compare \ the \ value \ with \ ay^2+by+c=0\na= 1\nb=3\nc=-3\n\ Formula: \ny= (-b\pm√(b^2-4ac))/(2a)\ny= (-3\pm √(9+12))/(2)\ny= (-3\pm √(21))/(2)\n

The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29
