Answer:

- 25 and - 623

Step-by-step explanation:

Using the term to term rule with u₀ = - 3 , then

(a)

u₁ = u₀³ + 2 = (- 3)³ + 2 = - 27 + 2 = - 25

(b)

u₂ = u₁³ + 2 = (- 25)³ + 2 = - 625 + 2 = - 623

Answer:

the answer is A

Step-by-step explanation:

Because

Multiply the first equation by 2  

6x-y=18

Both side multiply 2

12x-2y=36

And then subtract the second equation form the result,

12x-2y=36

4x+2y=26

16x=62

x=3.8

Answer:

I’m pretty sure it’s Triangle ABC is congruent to Triangle DEF.

Step-by-step explanation:

If you rotate Triangle DEF to where the 90 degree angle is on the bottom right, you can the compare the two triangles. You can divide 300/25, 240/20, and 180/15. They all result in 12 meaning they are congruent and similar in that way. (I’m only 90% this is right btw)

Answer:

-29/11

Step-by-step explanation:

i used a calculator lol

The point (-8, -3) is reflected on x-axis, we have (-8, 3) and the point is reflected on y-axis, we have (8, -3). Therefore, options A and E are the correct answers.

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

The given coordinate point A is (-8, -3).

Reflection on x-axis, we get

(-8, -3)→(-8, 3)

The reflection of point (x, y) across the y-axis is (-x, y).

Reflection on y-axis, we get

(-8, -3)→(8, -3)

Therefore, options A and E are the correct answers.

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]24x+10y\ge 200\\ \\ 12x+5y\ge 100[/tex]

Answer:

C. Neither

Step-by-step explanation:

The first equation is

This equation is already in the slope-intercept form;

The slope of this equation is 2.

The second equation is .

This equation is also already in the slope-intercept form.

The slope of this equation is .

Since the two slopes are not the same, the two lines are not parallel.

If these two lines are perpendicular, then the product of their slopes is -1.

But which is not equal to -1.

Therefore the two lines are also not perpendicular.

The correct choice is C.

and Length  of the lunch area is 6 1/2 times it's width.= 6 1/2  x Width

Length =   6 1/2 x 10 6/13

changing to improper fraction foe easy solving

13/2 x 136/13

13 cancels out 13, we are left with

136/2 =68 feet

Answer:

52 seeds.

Step-by-step explanation:

So, 3/4 of his plants have grown. SO, 3/4 = 39 plants, and if we divide by 3, we get 1/4 of the plants are 13 plants. SO, if we want to find 4/4, we can multiply 13*4=52 seeds.

Quincey planted 52 seeds in total.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

75% grew into mature plants.

If Quincey has 39 tomato plants in his garden.

let x number of seed he planted.

So, 75% of x= 39

75x/100= 39

75x = 3900

x = 52

Hence, He planted 52 seeds.
