Which choice shows y = 3x + 2 and y = 3x² correctly paired with their graphs?

Answer:

D

Step-by-step explanation:

Answer:

72 in

Step-by-step explanation:

a square has 4 sides so you divide 288 by 4 and get 72

the equation t² = 3 x + 1 will be written as x = t² / 3 - 1 / 3 with the subject as x.

We are given an equation:

t² = 3 x + 1

We need to solve it so that the subject becomes x.

For this, we will first subtract 1 from both the sides:

t² - 1 = 3 x + 1 - 1

3 x = t² - 1

Now, we will divide both the sides by 3

3 x / 3 = (t² - 1) / 3

x = t² / 3 - 1 / 3

So, the subject is being made as x now.

Therefore, we get that, the equation t² = 3 x + 1 will be written as x = t² / 3 - 1 / 3 with the subject as x.

Answer:

D. m = -15/1

Step-by-step explanation:

Slope Formula-

m = (y2-y1)/(x2-x1)

Using two random points-

(-1, 13) (0,-2)

-1 = x1

13 = y1

0 = x2

-2 = y2

m = (-2 - 13)/(0-(-1))

m = -15/1

Step-by-step explanation:

Step 1: Define

4/9 = x/36

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 4/9 does indeed equal 4/9.

∴ x = 16 is the solution to the equation.

Answer: 0 and -5

Step-by-step explanation:

Answer:

-5 and 0 make the inequality true.

Step-by-step explanation:

-5 and 0 are less than 1, making 1 and 5 greater than one (so 1 and 5 don't apply to this situation)

Given:

[tex]\ln(y-8)=-2x+\ln C[/tex]

To find:

y as a function of x.

Solution:

We have,

[tex]\ln(y-8)=-2x+\ln C[/tex]

It can be written as

[tex]\ln(y-8)=\ln e^{-2x}+\ln C[/tex]           [tex][\because \ln e^x=x][/tex]

[tex]\ln(y-8)=\ln (Ce^{-2x})[/tex]           [tex][\because \ln (ab)=\ln a+\ln b][/tex]

On comparing both sides, we get

[tex]y-8=Ce^{-2x}[/tex]

Adding 8 on both sides, we get

[tex]y=Ce^{-2x}+8[/tex]

Therefore, the equation function is [tex]y=Ce^{-2x}+8[/tex].

Answer:

Step-by-step explanation:

Answer:

(2x + 3)(x - 7)

Step-by-step explanation:

Given

2x² - 11x - 21

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 21 = - 42 and sum = - 11

The factors are - 14 and + 3

Use these factors to split the x- term

2x² - 14x + 3x - 21 ( factor the first/second and third/fourth terms )

= 2x(x - 7) + 3(x - 7) ← factor out (x - 7) from each term

= (2x + 3)(x - 7) ← in factored form

Answer:  Choice B.  k(h(g(f(x))))

For choice B, the functions are k, h, g, f going from left to right.

===========================================================

Explanation:

We have 4x involved, so we'll need f(x)

This 4x term is inside a cubic, so we'll need g(x) as well.

So far we have

g(x) = x^3

g( f(x) ) = ( f(x) )^3

g( f(x) ) = ( 4x )^3

Then note how we are dividing that result by 2. That's the same as applying the h(x) function

[tex]h(x) = \frac{x}{2}\\\\h(g(f(x))) = \frac{g(f(x))}{2}\\\\h(g(f(x))) = \frac{(4x)^3}{2}\\\\[/tex]

And finally, we subtract 1 from this, but that's the same as using k(x)

[tex]k(x) = x-1\\\\k(h(g(f(x)))) = h(g(f(x)))-1\\\\k(h(g(f(x)))) = \frac{(4x)^3}{2}-1\\\\[/tex]

This leads to the answer choice B.

To be honest, this notation is a mess considering how many function compositions are going on. It's very easy to get lost. I recommend carefully stepping through the problem and building it up in the way I've done above, or in a similar fashion. The idea is to start from the inside and work your way out. Keep in mind that PEMDAS plays a role.

The frequency tree will be 9 girls and 18 boys don't have a voucher.

Boys = 38

Girls = 22

Total = 60

Children who have a voucher = 33

Children who don't have a voucher = 60-33 = 27

Twice as many boys as girls do not have a voucher

Girls who don't have a voucher: x

Boys who don't have a voucher: 2x

Girls without voucher + boys without voucher: x + 2x = 27

3x = 27

x = 27/3

x = 9

Girls who don't have a voucher: x=9

Boys who don't have a voucher: 2x = 2(9) = 18

For frequency tree:

Total students: 60

Boys : 38

Boys who don't have a voucher : 18

Boys who have a voucher: 38 - 18 = 20
