Answer:

F(x) = 43/16 (43 over 16)

Answer:

1024

Step-by-step explanation:

Assuming you mean [tex]4^{5}[/tex] , then

[tex]4^{5}[/tex] = 4 × 4 × 4 × 4 × 4 ( 4 multiplied by itself 5 times )

  = 16 × 16 × 4

   = 256 × 4

   = 1024

Answer:

9 cm because 69

Step-by-step explanation:

Answer: −8x+24y+72

-8(x - 3y - 9)

=(-8)(x + -3y + -9)

=(−8)(x)+(−8)(−3y)+(−8)(−9)

=−8x+24y+72

Step-by-step explanation:

im not entirely sure but i hope this helps

:) have a nice day !!

Answer:

y variable will be elimited when adding the system of equations

x = 2 or y = 3

Step-by-step explanation:

- x + 6y = 16

8x - 6y = -2

Add both equations

(-x + 8x) + {6y + (-6y)} = 16 + (-2)

7x + 6y - 6y = 16 - 2

7x + 0 = 14

7x = 14

x = 14/7

x = 2

- x + 6y = 16

- 2 + 6y = 16

6y = 16 + 2

6y = 18

y = 18/6

y = 3

the x variable will be eliminating when adding the system of equations and the

y variable will be elimited when adding the system of equations

or the sum of the system equations is negative 8X = 14 or

x = 2 or y = 3

or there's only one solution to the system equations

Answer:

1.8b

Step-by-step explanation:

Hi there!

1.Subtract both terms:

[tex]6.5b-4.7b=1.8b[/tex]

2.Fraction form:

[tex]1.8b=1\frac{8}{10}b[/tex]

3.Simplifly the fraction term:

[tex]1\frac{8}{10}b*2=1\frac{4}{5}b[/tex]

Therefore, 6.5b-4.7b=1.8=1 8/10=1 4/5..

Answer:

yellow is 16% and purple is 20%

Step-by-step explanation:

Answer:

c/2=-4

c=-8

Step-by-step explanation:

Answer:

c = -8

Step-by-step explanation:

Okay, so this is a standard equation, so we have to do the thingy thing on each side:

c/2 + 5 - 5 = 1 - 5

c/2 = -4

c/2 x 2 = -4 x 2

c = -8

So, c = -8

Answer: 41/50

Step-by-step explanation:

Step 1: Write down the percent divided by 100 like this:

282% = 282/100

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As 282 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(282,100) = 2. So,

(282÷2)/(100÷2) = 141/50 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 282/100 is also equal to 2 41/50 when expressed as a mixed number.

Answer:

other root: x = 9

p = 7

Step-by-step explanation:

first, find p:

(8)² - (3p - 4)8 + 11p -5 = 0

64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0

91 - 13p = 0

-13p = -91

p = 7

plug in p to find the polynomial:

x² - (3(7) - 4)x + 11(7) - 5 = 0

x² - (21 - 4)x + 77 - 5 = 0

x² - 17x + 72

find the roots:

we know that 8 is one of the roots, so one factor is (x - 8)

the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8

that number is -9

so the poly nomial factors to be: (x-8)(x-9)

so the roots are x = 8 and x = 9

Answer:

p = 7

Step-by-step explanation:

x²-(3p-4)x+11p-5=0    ...(1)    Root: 8, x-8 is factor

(x-8) (x- (11p-5)/8) = 0

x² -8x - ((11p-5)/8)*x + (11p-5) = 0

x² - (8 + (11p-5)/8) x + 11p-5 = 0   ----(2)

compare(1) and (2): 3p-4 = 8 + (11p-5)/8

24p - 32 = 64 + 11p - 5

13p = 91

p = 7

check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

Answer:

its a fraction but you use proportions to find x

18. Not Linear

Step-by-step explanation:

Answer:

Bc = √63 ft

Step-by-step explanation:

Here, we want to get the length of BC

As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side

So we want to get the third leg which is BC

we can use the Pythagoras’ theorem here

And that states that the square of the hypotenuse equals the sum of the squares of the two other sides

let the missing length be x

12^2 = x^2 + 9^2

144 = x^2 + 81

x^2 = 144-81

x^2 = 63

x = √63 ft

Answer:

1:4

Step-by-step explanation:

Given

3: 12

To express in the form 1:n

Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3

3:12

= 3/3:12/3

= 1:4

Comparing with 1:n, it is safe to say that n = 4

Answer:

20x=y

Step-by-step explanation:

20 lawns times (x) number of lawns she mows is (y) the amount she makes.

Answer:

4.85

Step-by-step explanation:

Given :

Negative 0.2 (x minus 4) = negative 1.7

-2(x - 4) = - 1.7

-2x + 8 = - 1.7

-2x = - 1.7 - 8

-2x = - 9.7

Divide both sides by - 2

-2x / 2 = - 9.7 / - 2

x = 4.85
