Based on the graph, how many calories will Ian burn if he walks 4 miles?

A. 750
B. 800
C. 850
D. 900

Given x+x-¹ = 11

now square both the side

(x+x-¹)² = 11²

now open the bracket of RHS and apply (a+b)²

you'll get,

x²+2x/x+ 1/x² =121

simplify above equation you'll get,

x²+ 2 + x-² = 121

shift the equation,

x² + x-² = 121 - 2

x² + x-² = 119 !

Answer:

this is the correct answer

Answer:

Smaller number: 12

Greater number: 31

Step-by-step explanation:

Hi there!

Let x equal to the smaller number.

Let y be equal to the greater number.

1) Translate the information into equations

"One is 7 more than twice the other"

⇒ [tex]y=2x+7[/tex]

"The sum of the numbers is 43"

⇒ [tex]x+y=43[/tex]

2) Use substitution to solve for the smaller number

[tex]x+y=43[/tex]

Plug the equation [tex]y=2x+7[/tex] into the above equation

[tex]x+(2x+7)=43\\x+2x+7=43\\3x+7=43[/tex]

Subtract both sides by 7

[tex]3x+7-7=43-7\\3x=36[/tex]

Divide both sides by 3 to isolate x

[tex]\frac{3x}{3} = \frac{36}{3} \\x=12[/tex]

Therefore, the smaller number equates to 12.

3) Use substitution to solve for the greater number

[tex]x+y=43[/tex]

Plug in x as 12

[tex]12+y=43[/tex]

Subtract both sides by 12 to isolate y

[tex]12+y-12=43-12\\y=31[/tex]

Therefore, the greater number equates to 31.

I hope this helps!

Answer:

a) 42

b) -24

Step-by-step explanation:

Recordar las reglas de los signos:

(-)*(-) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(+)*(+) = (+)

Tambien la propiedad distributiva:

A*(B + C + D) = A*B + A*C + A*D

Queremos calcular:

a) (-7)*(+3)*(-2)  

Los primeros dos terminos dan:

-(7*3)*(-2) = -(21)*(-2) = (-21)*(-2) = +(21*2) = +42

b) -4*( + 3 - 2 + 5)

= (-4)*(3) + (-4)*(-2) + (-4)*(5)

= - 12 + 8 - 20 = 8 - 32 = -24

D) 5.65

Answer:

The sequence is geometric

The common ratio is 0.5

Step-by-step explanation:

In the arithmetic sequence, there is a common difference between each two consecutive terms

In the geometric sequence, there is a common ratio between each two consecutive terms

Let us check the given sequence

∵ The first 3 terms are 12, 6, 3

∵ 6 - 12 = -6

∵ 3 - 6 = -3

∵ There is no common difference between the consecutive terms

∴ The sequence is not an arithmetic sequence

∵ 6 ÷ 12 = 0.5

∵ 3 ÷ 6 = 0.5

∴ There is a common ratio between each two consecutive terms

∴ The sequence is a geometric sequence

∴ The common ratio is 0.5

Answer:

36

Step-by-step explanation:

the first sequence starts

4 12 (3*4) 36 (3*12) 108 (3*36) ...

the second sequence starts

20 28 (8+20) 36 (8+28) 44 (8+36) ...

so, just by writing down a few elements you can see it already.

I knew it already before that just by thinking "the first sequence has only numbers that can be divided by 3. what is the first number of the second sequence that can be also divided by 3 ? oh, yeah, 36 !"

Answer:

2nd option

Step-by-step explanation:

Consider the coordinates of A and A'

A (2, - 2 ) → A' (- 4, 1 )

This is a shift of - 6 in the x- direction and + 3 in the y- direction

Then the translation rule is

(x, y ) → (x - 6, y + 3 )

Answer:

Paul is 16 years old.

Julie is 8 years old.

Step-by-step explanation:

If Julie is 8 years old and Paul is 16 yearss old, this makes Julie half as old as Paul but also makes Paul 8 years older than Julie.

Answer:

y = -1/4x^2 - x + 3

Step-by-step explanation:

(-6,0)

(-4,3)

(2,0)

36a - 6b + c = 0

16a -4b + c = 3

4a + 2b + c = 0

c = -4a - 2b

36a - 6b - 4a -2b = 0

16a - 4b -4a - 2b = 3

32a -8b = 0

12a - 6b = 3

4a - b  = 0

4a - 2b = 1

b = -1

4a + 1 = 0

4a = -1

a = -1/4

c = 1 + 2 = 3

y = -1/4x^2 - x + 3

Answer:

Step-by-step explanation:

y = ax² + bx + c

( - 6)²a - 6b + c = 0 ⇒ 36a - 6b + c = 0

( - 4)²a - 4b + c = 3 ⇒ 16a - 4b + c = 3

2²a + 2b + c = 0 ⇒ 4a + 2b + c = 0

A = [tex]\left[\begin{array}{ccc}36&-6&1\\16&-4&1\\4&2&1\end{array}\right][/tex] = - 96

[tex]A_{a}[/tex] = [tex]\left[\begin{array}{ccc}0&-6&1\\3&-4&1\\0&2&1\end{array}\right][/tex] = 24

[tex]A_{b}[/tex] = [tex]\left[\begin{array}{ccc}36&0&1\\16&3&1\\4&0&1\end{array}\right][/tex] = 96

[tex]A_{c}[/tex] = [tex]\left[\begin{array}{ccc}36&-6&0\\16&-4&3\\4&2&0\end{array}\right][/tex] = - 288

a = [tex]\frac{A_{a} }{A}[/tex] = [tex]\frac{24}{-96}[/tex] = - [tex]\frac{1}{4}[/tex]

b = [tex]\frac{A_{b} }{A}[/tex] = - 1

c = [tex]\frac{A_{c} }{A}[/tex] = 3

y = - [tex]\frac{1}{4}[/tex] x² - x + 3
