Answer:

Julie is 4

Step-by-step explanation:

First you need to do 8 divided by 2 because she is half as old.

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:

10.2% but there is a chance of it being 8.8%

Step-by-step explanation:

there are total of 18 marbles to start

of this at the begining there is a 8/18 chance to draw a marble, now here is where it can get tricky so ive organized them into different groups, A and B

Option A: The Marbles are removed after

this would make the problem be 8/18 x 7/17 x 6/16

4/9 x 7/17 x 3/8 or 84/1224

simplify 42/612

simplify 21/306

(21/306) x 100 = 10.2%

Option B: The Marbles arent removed after

8/18 x 8/18 x 8/18

4/9 x 4/9 x 4/9

64/729 = .08779

.08779 x 100 = 8.8

8.8%

It depends on what youve learned in class, i would go with option A

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

Answer:

Its in the picture so you can understand it better.

Step-by-step explanation:

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

Answer:

the last one

Step-by-step explanation:

I took the test

We know that :

Ф  Product of the slopes of two lines perpendicular to each other should be equal to -1

Let the slope of the line perpendicular to given line be : M

Given equation of the line : y = -1/2x + 4

This line is in the form : y = mx + c, where m is the slope and c is the y intercept

Comparing with y = mx + c :

we can notice that slope of the given line is -1/2

⇒   M × -1/2 = -1

⇒   M × 1/2 = 1

⇒   M = 2

Answer : Slope of the line perpendicular to given line is 2

Answer:

The correct answer is Adam rowed faster in the men's 500-meter kayak race.

Step-by-step explanation:

To find the speed he rowed in both races, you need to divide the distance of the race by the time it took him to finish. In the first race, he rowed 500 meters and did it in a time of 1 minute 37.9 seconds, so the speed in that race would be [tex]\frac{500}{97.9}[/tex] or approximately 5.10725 meters per second. In the second race, Adam rowed a distance of 1000 meters and did it in a time of 3 minutes 28.2 seconds, which means his speed in that race would be [tex]\frac{1000}{208.2}[/tex] or approximately 4.80307 meters per second. Since his speed in the first race was faster than his speed in the second race, Adam rowed faster in the first race would be the correct answer.

Answer:

Step-by-step explanation:

Answer:

$207.66

Step-by-step explanation:

30% off is the same as saying there is 70% not off, and 70% is the same as 0.70

0.70*349= 244.30

15% off is the same as saying 85% is not off, and

85% is the same as 0.85

0.85*244.30=207.655

because it's money, you round to 2nd decimal place

$207.66

hope this was helpful :)

Answer:

15 mL?

Step-by-step explanation:

Answer:

(-2^2)^-6 / (2^-5)^-4  --->  2^-32

(2^2)^2  x  (2^3)^-3   --->  2^-5

2^4  x  (2^2)^-2  --->  1

(-2^-4)^-2  x  (2^2)^0  --->  2^8

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!

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 !

Ok I will watch out:3

Thnx for telling us :3

I hope you are having a great day ❤️❤️❤️❤️

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 )
