Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

40 = 29 + x

Answer:

61 miles

Step-by-step explanation:

1 / 6 = 1/6

1/6 * 366 = 61

1/6 of 366 is 61

We can check our answer by multiplying 61 and 6 since we divided 366 and 6

61 * 6 = 366

Now that we have checked our answer, we can comfirm that 366 divided by 6 is 61 therefore, our answer is 61 miles in 1 hour

Answer:

[tex]x^{2}[/tex]-25

Step-by-step explanation:

formula for areas of rectangles= width x height

width=x-5

height=x+5

(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25

since the 5x's cancel out each other

              =[tex]x^{2}[/tex]-25 will be the answer

The area of rectangle is [tex](x^{2} -25)[/tex] unit square.

The area of rectangle is product of length and width.

         [tex]Area = length*width[/tex]

Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].

    [tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]

Hence, the  area of rectangle is [tex](x^{2} -25)[/tex] unit square.

Answer:

-6<-2?

Step-by-step explanation:

Answer: I think it’s

f ` (x) = - 8 / x²

f ` (11) = - 8 / 121

The value of the derivative at x = 11 is 8/121

The equation of the function is given as:

[tex]f(x) = -\frac 8x[/tex]

Rewrite the above equation as:

[tex]f(x) = -8x^{-1}[/tex]

Using the first principle, the derivative of f(x) is:

[tex]f'(x) = -1 \times -8x^{-1-1}[/tex]

[tex]f'(x) = -1 \times -8x^{-2}[/tex]

Evaluate the product

[tex]f'(x) = 8x^{-2}[/tex]

Rewrite the above equation as:

[tex]f'(x) = \frac{8}{x^2}[/tex]

Substitute 11 for x

[tex]f'(11) = \frac{8}{11^2}[/tex]

[tex]f'(11) = \frac{8}{121}[/tex]

Hence, the value of the derivative at x = 11 is 8/121

Answer:

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(a)

The angle around the centre O of the circle = 360°, then

∠ AOB = 360° - 260° = 100°

Δ AOB is isosceles ( the radii OA and OB are congruent )

The altitude from O bisects ∠ AOB , thus

y = 50°

Since the triangle is isosceles the 2 base angles are congruent, so

x = [tex]\frac{180-100}{2}[/tex] = [tex]\frac{80}{2}[/tex] = 40°

(b)

∠ POR = 360° - 254° = 106°

Δ POR is isosceles (the radii OP and OR are congruent ) , then

the 2 base angles are congruent , thus

a = [tex]\frac{180-106}{2}[/tex] = [tex]\frac{74}{2}[/tex] = 37°
