Answer:find the solution to the system of equations below.start by adding the equation

{-2x+2y=-8

{2x+y=5

Step-by-step explanation:The given system of equation are:

1----  y= x -4

2----- y=4 x+2

Equation (1) - Equation (2)

→0= x -4 - (4 x+2)

→0=  -3 x -6-----[Adding and subtracting like terms]

Adding 3 x on both sides

→3 x= -6

Dividing by 3 on both sides

→x = -2

→Substituting the value of x in equation 1, we get

y= -2 -4

y =-6

→Solution set =(x,y)=(-2, -6)

Don't used the graph to find the solution.

If my answer is wrong so I am really sorry for it

Answer:

2.2

Step-by-step explanation:

If you know your derivative rules, then

d/dx [1/x] = -1/x ²

so that when x = 6, the derivative has a value of -1/36.

If you have to use the definition of the derivative, then

d/dx [1/x] = lim {h → 0} (1/(x + h) - 1/x) / h

… = lim {h → 0} (x - (x + h)) / (hx (x + h))

… = lim {h → 0} (-h) / (hx (x + h))

… = lim {h → 0} (-1) / (x (x + h))

… = -1/x ²

and at x = 6, you again get -1/36.

Alternatively, use the definition of the derivative at a point:

d/dx [1/x] (6) = lim {x → 6} (1/x - 1/6) / (x - 6)

… = lim {x → 6} ((6 - x) / (6x)) / (x - 6)

… = lim {x → 6} -(x - 6) / (6x (x - 6))

… = lim {x → 6} (-1) / (6x)

… = -1/36

Given:

The geometric sequence is

[tex]4, -12, 36,...[/tex]

To find:

The sum of first 8 terms of the given geometric sequence.

Solution:

We have,

[tex]4, -12, 36,...[/tex]

Here, the first term is 4 and the common ratio is

[tex]r=\dfrac{-12}{4}[/tex]

[tex]r=-3[/tex]

The sum of first n terms of a geometric sequence is

[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]

Where, a is the first term and r is the common ratio.

Putting n=8, a=4 and r=-3, we get

[tex]S_8=\dfrac{4((-3)^8-1)}{-3-1}[/tex]

[tex]S_8=\dfrac{4(6561-1)}{-4}[/tex]

[tex]S_8=-6560[/tex]

Therefore, the sum of first 8 terms is -6560.

Answer:

circumference=15.7 feet

Step-by-step explanation:

5x3.14=circumference=15.7

Answer:

15.7 feet

Step-by-step explanation:

The formula for circumference is [tex]2\pi r[/tex].

The radius is half of the diameter: 2.5 in this case.

2.5 x 2 is 5.

3.14 x 5 is 15.7.

Answer: 75.75°

Step-by-step explanation:

Sine is the opposite of the angle divided by the hypotenuse. The opposite side of the angle is 12.6 and the hypotenuse is 13.

sin(Ф) = 12.6/13

Take the inverse sine of both sides, this requires a calculator.

Ф = 75.75°

What is fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

According to questions, Last year Zack had two jobs.

Zack worked  in an office for [tex]12[/tex] months and earned  £[tex]2600[/tex] per month

and at a gym for [tex]39[/tex] weekends and earned £[tex]80[/tex] per weekend.

We have to find the fraction of his total income last year came from his work at the gym.

Office Income[tex]=[/tex]£[tex](2600[/tex]×[tex]12[/tex][tex])[/tex]  [tex]=[/tex]£[tex]31200[/tex]

Gym Income[tex]=[/tex]£ [tex](80[/tex]×[tex]39)[/tex][tex]=[/tex] £[tex]3120[/tex]

Total Income[tex]=[/tex]£ [tex]34320[/tex]

Fraction of his total income last year came from his work at the gym  

[tex]=\frac{3120}{34320} \\=\frac{1}{11}[/tex]

[tex]=0.909[/tex]

Hence, we can conclude that [tex]\frac{1}{11}[/tex] [tex]=0.909[/tex] of his total income last year came from his work at the gym.

Answer: y=-2x+6

Step-by-step explanation:

The equation for slope-intercept form is : y=mx+b

----------------------------------------------------------------

First Step: find the slope

- (y2-y1)/(x2-x1)

GIven

x1=0

y1=6

x2=4

y2=-2

Solve

 (y2-y1)/(x2-x1)

=(-2-6)/(4-0)

=-8/4

=-2

Second Step: find the y-intercept

Given

y=-2x+b

Substitute one of the points into the equation

y=-2x+b

(-2)=-2(4)+b

-2=-8+b

b=6
