Study the equations:

f(x) = 6x + 7

g(x) = 4x – 2

What is h(x) = f(x)g(x)?

h(x) = 24x2 – 14
h(x) = 24x2 + 40x + 14
h(x) = 24x2 + 16x – 14
h(x) = 24x2 + 12x – 14

Answers

Answer 1
h(x) = (6x + 7)(4x - 2)

Use FOIL Method (First, Outer, Inner, Last)

h(x) = 24x^2 - 12x + 28x - 14

Combine like terms.

h(x) = 24x^2 - 16x - 14
Answer 2

Answer:

h(x)=24X^2+40x+14

The morning low tide at the beach is 12 inches. After 6 hours, the afternoon high tide is 57 inches. What is the average number of inches the tide changed per hour?

Answers

Answer:

7.5 inches per hour

Step-by-step explanation:

Given that:

Morning low tide at beach = 12 inches

Afternoon tide after 6 hours = 57 inches

Average number of inches tide changed per hour :

(Afternoon tide - morning tide) / number of hours

(57 inches - 12 inches) / 6 hours

45 inches / 6 hours

= 7.5 inches per hour

14)   C (-2, 4)

15)   D (-3, -3)

Step-by-step explanation:

-6x + 4y = 28

6x + 9y = 24

-6x + 4y = 28

4y = 28 + 6x

y = 7 + 1.5x

6x + 9y = 24

6x + 9(7 + 1.5x) = 24

6x + 63 + 13.5x = 24

19.5x + 63 = 24

19.5x = -39

x = -2

-6x + 4y = 28

-6(-2) + 4y = 28

12 + 4y = 28

4y = 16

y = 4

____________

4x - 4y = 0

-4x + 3y = 3

4x - 4y = 0

4x = 4y

x = y

-4x + 3y = 3

-4(y) + 3y = 3

-4y + 3y = 3

-1y = 3

y = -3

4x - 4y = 0

4x - 4(-3) = 0

4x + 12 = 0

4x = -12

x = -3

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement

Answers

Answer:

r+c=80

.50r+.10c=20

Step-by-step explanation:

each rose costs $0.50

each carnation costs $0.10

The number of roses is r, and the number of carnations is c.

the arrangement has a total of 80 flowers, so we have that:

r + c = 80

the cost is $20, so we have:

r*0.5 + c*0.1 = 20

so our system of equations is:

r + c = 80

r*0.5 + c*0.1 = 20

and we can also solve it; for this isolate one of the variables in the first equation:

r = 80 - c

now let'r replace this in the second equation:

(80 - c)*0.5 +c*0.1 = 20

40  - c*0.4 = 20

c = 20/0.4 = 50

this means that we have 50 carnations, and the other 30 are roses.

Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?

Answers

Answer: I think the answer is 32 bacteria after 40 minutes.

Step-by-step explanation:

I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

for m(x)=-2x+7, find the value of x for which m(x)=13

Answers

Answer:

x = -3

Step-by-step explanation:

m(x) = -2x + 7

13  = -2x + 7

6 = -2x

x = -3

The answer is x= -3




The explanation if you need it is since m(x)=13 we get the equation 13=-2x+7. Then we use the equation to find x.


13= -2x+7
-7 -7
6= -2x
— —
-2 -2

-3=x

You then want to check your answer by substituting -3 for x

13= -2(-3) +7
13= 6+7
13=13
If your answers match then your answer is correct
