a im not to sure but tjats what I got

Answer:

(g°f)(4) = -1296

Step-by-step explanation:

It is given that:

g(x) = -6x² - 86x - 8

f(x) = 4x - 2

First find the equation of (g°f)

(g°f) = g [ f (x) ]

(g°f) = g [ 4x-2 ]

Substitute 4x-2 for x in formula of g(x)

g(x) = -6x² - 86x - 8

g(4x-2) = -6(4x - 2)² -8(4x - 2) - 8

g(4x-2) = -6(16x² + 4 - 2(4x)(2)) - 32x + 16 - 8

g(4x-2) = -96x² - 24 +96x - 32x + 16 - 8

g(4x-2) =  -96x² + 64x - 16

(g°f)(x) =  -96x² + 64x - 16

Substitute x=4 into the equation:

(g°f)(4) =  -96(4)² + 64(4) - 16

(g°f)(4) = -1296

Answer A is correct. C is correct.

Answer:

hello

Thanh have 3,5 meters of fabric. i can say

3,5/1 for it.

and i can say 35/10

now he used three-fourths of a meter of fabric.

its equal to 3/4

now i have to remove 3/4 from 35/10.

35/10 - 3/4

denominators have to be same thats why im expanding them to 20.

35×2/10×2 = 70/20

3×5/4×5 = 15/20

now i can remove 15/20 from 70/20!

70/20 - 15/20 = 55/20

we cannot see 55/20 in the options.

thats why im dividing them with 5.

55÷5= 11 20÷5=4

the answer is 11/4

11/4 = 2and 3/4

so its option 2

good luck(:

Answer: $2400

Step-by-step explanation:

SI = Prt / 100

SI = 2000 x .04 x 5

SI = 400

FInal Amount = 2000 + 400 = $2400

Step-by-step explanation:

[tex]\frac{55}{4} y=\frac{-69}{4}[/tex]

[tex]y=\frac{-69}{55}[/tex]

[tex]x=\frac{-9(-69/55)-11}{4}\\x=\frac{4}{55}[/tex]

Answer:

(- 4, - 3 )

Step-by-step explanation:

Given the 2 equations

- 4x + 9y = - 11 → (1)

- 3x + 7y = - 9 → (2)

Multiplying (1) by 3 and (2) by - 4 and adding will eliminate the term in x

- 12x + 27y = - 33 → (3)

12x - 28y = 36 → (4)

Add (3) and (4) term by term to eliminate x

- y = 3 ( multiply both sides by - 1 )

y = - 3

Substitute y = - 3 into either of the 2 equations and evaluate for x

Substituting into (1)

- 4x + 9(- 3) = - 11

- 4x - 27 = - 11 ( add 27 to both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4

Solution is (- 4, - 3 )

Answer:

$78,000

Step-by-step explanation:

Because their are 52 weeks in a year and 52 X 1500 is $78,000

Answer:

Since there are 52.14 Weeks in a year you would multiply how many weeks there are in a year and how much Mr.white gets paid weekly and you get $78,210 in year.

Answer:

Step-by-step explanation:

When we plan an effective budget, we certainly need to gather some data about the theme, which includes, prices, description of the stuff we need. Once we have the data we need, then we must organize it to set priorities, to make the budget effective.

Additionally, estiamting and finding averages are important skills, because we need to estimate how effective is the budget. In fact, maybe we would desing different budgets to compare them and analyse, using averages, which one is the most effective.

Answer:

35/80

u want to find a number that is proportional to 35/80, then all u need is a number that is equivalent...another words, if it is proportional, it is an equivalent fraction to 35/80.

there can be several answers to this...such as 35/80 reduces to 7/16...so 7/16 is proportional....or if u multiply numerator and denominator by the same number, u will find a proportional number...

example :

35/80 * 2/2 = 70/160...this is proportional

35/80 * 3/3 = 105/240...this is proportional

35/80 * 4/4 = 140/320...this is also proportional

and so on....

so without giving us any answer choices, there can be many numbers to choose from

Answer:

its a slope....

Answer:

One solution

Step-by-step explanation:

-t+5=7

-t=2

t=-2

Answer:

One solution: t = -2.

Step-by-step explanation:

To figure out how many solutions an equation has, it would be best to compute the solution first.

Given:

3t + 5 = 4t + 7 // Subtract 3t from both sides.

5 = t + 7 // Subtract 7 from both sides.

t = -2.

Answer:

12 miles

Step-by-step explanation:

6 times 2 = 12

Answer:

The distance between the 6th and 10th seat is approximately 126m

Step-by-step explanation:

First of all, we will need to calculate the circumference of the circular fair ride.

This is [tex]2\pi r= 2 \times \pi \times 60=377m[/tex]

hence the circumference of the circle is 377m

At this point, we will have to take note that the pods are equally spaced.

To get the distance between the sixth pod and the tenth pod, we will have to use the principle of fractions of a whole.

There are 12 seats in total, the distance between the 6th and tenth seat is 4 seats. Expressing this distance in terms of seats, as a fraction is 4/12 equally spaced seats.

This ratio can be related to the circumference of the circle as

[tex]\frac{4}{12} \times377=125.66m \approx 126m[/tex]

Therefore, the distance between the 6th and 10th seat is approximately 126m

Answer:

B) They will have the same amount in week 4.

Step-by-step explanation:

Jose:  y = -25x +250

Martin: y = 30x + 30

Plug in 6

Jose: y = -25(6) + 250    y = 100

Martin: y = 30(6) +30      y = 2100

Plug in 4

Jose: y = -25(4) + 250      y = 150

Martin: y = 30(4) + 30         y = 150

Answer:

D.) 68 units²

Step-by-step explanation:

The formula for the area of a triangle is:

A = bh/2

where b is the base and h is the height

Substitute the given values into this formula:

A = bh/2

A = (17)(8)/2

Solve:

A = (17)(8)/2

A = 136/2

A = 68

Therefore, the area is 68 square units.
