Answer:

-[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Step-by-step explanation:

1/3 with both sides multiplied by two in order to have same denominator of both fractions, which is 6.

(1/3) x (2/2) = 2/6

Replacing 1/3 with 2/6,

the [ 1/3 - 5/6] becomes [2/6 - 5/6]

2/6 - 5/6 = -3/6

Simplify -3/6 by dividing both sides with 2,

-3/6 becomes -1/2

ANSWER: -1/2

Answer:   [tex]\huge\boxed{\ m=7 }[/tex]

Step-by-step explanation: We can break this problem down to understand it.  Let the number be m. Three times the number 'm ' is 3.m or 3m. 3 ( m ) - 6 = 15. 3m -6 = 15 add 6 to both sides; 3m -6 + 6 = 15 + 6 3m = 21 dividing both the sides by 3 ,and  we get; 3m /3 = 21 / 3 m=7 .

Answer:

26/20

Step-by-step explanation:

y2-y1 divided by x2-x1

4-24= -20

3-29= -26

-20/-26= m

perpendicular means to switch the numbers and change the sign

a perpendicular slope to -20/-26 is 26/20.

Answer:

∠ GJK = 22°

Step-by-step explanation:

∠ HJI = ∠ JHG ( alternate angles ), then

7x - 16 = 5x + 8 ( subtract 5x from both sides )

2x - 16 = 8 ( add 16 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12 , so

∠ KJI = 7x - 16 = 7(12) - 16 = 84 - 16 = 68°

Then

∠ GJI = 90° ( vertex of a rectangle )

∠ GJK = 90° - 68° = 22°

Answer: 4

Step-by-step explanation:

Use the triangle to the right to find the measure of the side the two triangles share. That side is 8.06 roughly and squared it’s 65. I used the 65 to solve for b in a^2 + b^2 = c^2

65 + b^2 = 81

b^2 = 16

b = 4

Answer:

v = 20 Sundaes

Step-by-step explanation:

Total number of sundaes = 25

Let the number of mint = m = 1/5 of total

= 1/5 of 25 = 1/5 × 25 = 5

∴ m = 5

Remainder = 25 - 5 = 20 Sundaes

let the number of chocolate = c = 1/2 of the remainder

1/2 of remainder = 1/2 of 20 = 20 ÷ 2 = 10 sundaes

∴ c = 10

let the number of vanilla = v

Therefore, finding v

25 = m + c + v

25 = 5 + 10 + v

25 = 15 + v

25 - 15 = v

v = 20 Sundaes

Step-by-step explanation:

The equation of the red graph is [tex]x^{2} +2[/tex].

The equation of the parabola whose vertex is (h, k) is

[tex]y = a(x-h)^{2} + k[/tex]

According to the given question.

We have a graph for the function f(x) and g(x).

[tex]f(x) =x^{2}[/tex]..(i)

⇒ the equation of parabola whose vertex is (0, 0)

Since, we know the standard form of the  equation of parabola is

[tex]y = a(x-h)^{2} +k[/tex]

Substitute h = 0 and k = 0 in the above equation.

⇒ [tex]y = a(x-0)^{2} +0[/tex]

⇒ [tex]y = ax^{2}[/tex]..(ii)                          (where, y = f(x))

On comparing the first two equations we get a = 1.

From the graph we can see that g(x) is a equation of parabola, whose vertex is (0, 2).

Therefore, the equation for red graph is given by

[tex]g(x) =a(x-0)^{2} + 2[/tex]

[tex]g(x) = 1x^{2} +2[/tex]                 (because a = 1)

⇒ [tex]g(x) = x^{2} +2[/tex]

Hence, option c is correct.

Answer:

There will be 10 cats in 5 years

Step-by-step explanation:

Since x means the number of years, x = 5

According to PEMDAS, we take care of the exponents first

So the exponent is x, so the exponent is actually 5

So we apply that to 0.28

0.28^5 = 0.002

0.002 x 5719 = 9.84

But... that would be impossible and just plain creepy if there were 9.84 cats lol

So I rounded it to 10 cats

Answer:

[tex]\Large\boxed{\sf 10 \ cats}[/tex]

Answer:

Cameron will do 79 jumping jacks on Sunday

Step-by-step explanation:

So on Wednesday, he did 4 jumping jacks. On Thursday, he did 5 more jumping jacks than he did on Wednesday (9 total ). On Friday, the difference between Wednesday and Thursday doubled, and it has a difference of 10 new jumping jacks(19 total). On Saturday, the difference between Thursday and Friday doubled from 10 to 20, (39 total). So if the difference keeps up, which it should, The difference between Saturday and Sunday should double from the diffeerence from Friday to Saturday (a difference of 20). So if the difference is doubled, it will be a difference of 40. so 39+40=79.

Answer:

8 boxes of tissues

5 bags of cough drops

Step-by-step explanation:

You need to write a system of equations.

x = number of tissue boxes

y = number of cough drop bags

x (number of tissue boxes) + y (number of cough drop bags) = 13 (total number of tissues and cough drops combined.

So, your first equation is

x + y = 13

Then, you need to write the second equation.

(1.69 [cost of 1 tissue box] * [number of tissue boxes]) + (1.19 [cost of one bag of cough drops] * [number of cough drop bags] = 19.47 [total cost of tissues and cough drops]

That's a lot to read, so here's the equation simplified!

1.69x + 1.19y = 19.47

Now, you have two equations:

x + y = 13

1.69x + 1.19y = 19.47

I would solve with the substitution method.

the first equation can be changed to x = 13 - y by subtracting y from both sides.

Then, your two equations are:

x = 13 - y

1.69x + 1.19y = 19.47

Now, you can plug in that value of x into the second equation!

1.69(13 - y) + 1.19y = 19.47

21.97 - 1.69y + 1.19y = 19.47

subtract 21.97 from both sides

-1.69y + 1.19y = -2.5

Add the y values

-0.5y = -2.5

divide both sides by -0.5

so, y equals 5 bags of cough drops

now that you know what y equals, plug it back into your original equation to find x!

x + y = 13

plug in y

x + 5 = 13

x = 8

so, x = 8 boxes of tissues

Answer:y=7(2)^x

Step-by-step explanation:

The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.

Exponential functions are functions where the independent variable, x is in the exponent.

The general form of exponential function is,

f(x) = abˣ

The function passes through (0,7) and (9, 3584).

Substituting (0, 7),

7 = a b⁰

7 = a  (since b⁰ = 1)

So, a = 7

Function is f(x) = 7bˣ

Now Substituting (9, 3584),

3584 = 7 b⁹

b⁹ = 3584 / 7

b⁹ = 512

b⁹ = 2⁹

b = 2

So the function is f(x) = 7(2)ˣ

Hence the function is f(x) = 7(2)ˣ.
