−5x + y = −3
3x − 8y = 24

Answers

Answer 1

Answer:

x = 0

y = -3

Step-by-step explanation:

-5x + y = -3 --------------(I)

3x - 8y = 24 ------------(II)

Multiply the equation (I) by 8

(I)*8    - 40x + 8y = -24

(II)         3x -  8y   =  24   {Add and y will be eliminated}

           -37x          = 0

                     x     = 0

Plugin x = 0  in equation(I)

-5*0 + y = -3

     0 + y = -3

           y = -3

Answer 2

Answer:

- 5x + y =-3    ......1

3x -8y = 24.........2

eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3

-40 x +8 y =-24 ...........3

3 x   - 8y  = 24     ......... 2

·································

-37 x +0 = 0

··························

x =0

put x = 0 in equation 2

3 x -8 y =24

3×0 -8 y = 24

0 -8 y=24

-y =24÷8

-y =3

y = -3

ans ;

x = 0

y = -3

In the xy-plane, the graph of which of the following equations is perpendicular to the graph of
the equation above?
•y=-3/2x-10 •y=-2/3x+10 •y=2/3x+10 •y=3/2x-10

Answers

Answer is y=-2/3x+10
Explanation
Subtract 2x to 10
3y= -2x + 10
Divide by 3
Y= -2/3x+10

The graph formed by equation y= -2/3x+10 will be perpendicular to the graph by equation y=3/2x-10.

What is the slope of any line?

A line in the form of ax + by + d = 0 will be a linear equation and if we convert it into the form of y = mx + c where m will be the slope of that equation.

If two lines are perpendicular to each other then the product of their slope of them will be (-1).

⇒  m₁ ₓ m₂ = -1

The slope of line 2x + 3y = 10 will be -2/3

To be any line perpendicular whose slope m with the 2x + 3y = 10

⇒ -2/3 × m = -1

⇒   m = 3/2 so the slope of that line should be 3/2

Hence, line y=3/2x-10 will be perpendicular to the 2x + 3y = 10.

x + 15x + 24 = -21 - 4x​

Answers

Answer:

x= -9/4

Step-by-step explanation:

1) Isolate X

2) This will give you x+15x+4x=-21-24

(moving terms to another side will make it opposite, in this case positive 24 moving to the right will become negative 24)

3) Add the like terms

x+15x+4x = 20x

-21-24= -45

this will give you 20x=-45

4)Find the value of X by moving the 20 multiplier to the other side (this will become the opposite, division of 20)

x= -45/20

5) Simplify your answer

Answers

Answer:

37.6 in

48.2 yd

Step-by-step explanation:

The are of a circle is given as :

Area = pi(d²) /4

Area = 1110.4in²

1110.4 = 3. 14 * d² / 4

1110.4 * 4 = 3.14 * d²

4441.6 = 3.14d²

d² = 4441.6 /3.14

d² = 1413.8051

d = 37.600

d = 37.6

8.)

Area, A = 1824.7yd²

1824.7 = 3. 14 * d² / 4

1824.7 * 4 = 3.14d²

7298.8 = 3.14d²

d² = 7298.8 / 3.14

d² = 2323.2801

d = sqrt(2323.2801)

d = 48.200

Hence, diameter = 48.2 yd

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn

Answers

The question is incomplete. The complete question is :

Nate starts a lawn-mowing business. In his business, he has expenses and revenue. Nate's expenses are the cost of the lawn mower and gas, and his revenue is $25 per lawn. At what point will Nate's revenue exceed his expense?

Cost of lawn mower = $ 200

Cost of gasoline = $ 2 per lawn

Solution :

Given :

Cost of the lawn mower = $ 200

The cost of gasoline expense for one lawn = $ 2

The revenue generated for one lawn = $ 25

So let the number of lawn to be mowed = x

Therefore the total expenses = [tex]$200+2x$[/tex]

So, the total revenue = [tex]$25x$[/tex]

The point for which the revenue will exceed the total expenditure will be :

[tex]$25x \geq 200+2x$[/tex]

So at [tex]x=9, \ 225 > 218[/tex]

Thus the revenue exceeds the total expenditure after mowing 9 number of lawns.

Answer:

For part a and b of this question

Step-by-step explanation:

x= # of lawns cut      y= total cost

revenue: y=25x

cost: y= -2x-200

He earns 25 per lawn, but loses $200 for his lawnmower and $2 per lawn.

b.  y=25x            y=-2x-200                    y=25x              

    y=-2x-200     25x=-2x-200                y=25(-7.40)

                              27x= -200                 y=-185

                                   x=-7.40

I believe this is correct.

Answers

Answer: D (3,4) trust and believe

Step-by-step explanation:

When a line or shape or point is rotated, it must be rotated around a point.

The image of the point is D. (3,4)

The point is given as:

[tex]\mathbf{(x,y) = (-3,-4)}[/tex]

A 180-degree rotation across the origin is represented as:

[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]

Substitute values for the coordinates of the point (x,y)

[tex]\mathbf{(-3,-4) \to (-(-3),-(-4))}[/tex]
