Answer 1

Answer:

-1 and 6

Step-by-step explanation:

The zeros of the function f(x) is where f(x) hits the x axis (or also known as x-intercepts)

In this case, the points where the graph f(x) touches the x axis are (-1,0) and (6,0).

Therefore, the zeros of the function are -1 and 6.

you could bowl 3 times (it starts off at 6.75 because I took away the cost of the shoes)

Answer:
3 games.

Explanation:
$2.50 is a one time cost so we want to subtract that from $9.25 to see how many games we can play. This leaves us with $6.75.
Next, we divide $6.75 / $2.25 = 3.
This means the total amount of games one can play is 3.

Priyanka drives at 45km/h and reaches Delhi in 5 hours.What time will she take to complete the same journey if she increases her speed by 5km/h ?​

Answers

Answer: Increasing her speed  by 5km/h, she will take 4.5 hours to complete the journey.

Step-by-step explanation:

Step 1

Speed= Distance  / TIme

Given Speed = 45km/h

and Time = 5 hours

Distance covered = Speed x Time

= 45 km/h x 5 hours

=225 kilometres.

Step 2

Increasing her speed by 5km/h makes the new Speed = 45 +5 = 50 km/h

At the same Distance of 225 km

Therefore she will complete the journey in

Time = Distance/ Speed

=225km/ 50km/h

=4.5 hours

find the product (3x - 5) (3x + 5)​

Answers

Answer:

9x ^2 − 25

 

Explanation:

( a + b ) ( a − b ) = a ^2 − ^b 2

substitute  a  with  3 x  and  b  with 5:

( 3 x + 5 ) ( 3 x − 5 ) = ( 3 x ) 2 −5^ 2 = 9 x ^2 − 25

( 3 x + 5 )( 3 x − 5 ) =  9 x ^2 − 25

Answer:

9x² - 25

Step-by-step explanation:

(a - b)(a + b)= a² - b²

a = 3x   ; b = 5

(3x - 5 )(3x + 5)= (3x)² - 5²

                        = 3²x² - 25

                        = 9x² - 25

Kayla bought 8 hot dogs and hamburgers for her and her friends. Hot dogs cost $1.50 and hamburgers cost $1.75. If she spent a total of $13.25, how many hot dogs did she buy?

Answers

Answer:

5 hamburgers and 3 hot dogs

Step-by-step explanation:

D = number of hot dogs

H = number of hamburgers

D + H = 8    then  D = 8 - H

1.50D + 1.75H = 13.25

substitute for D

1.50(8-H) + 1.75H = 13.25

12-1.50H + 1.75H = 13.25

subtract 12 from each side

-1.50H + 1.75H = 1.25

0.25H = 1.25

divide both sides by 0.25

H = 5

D = 8-5

D = 3

Answers

Answer:

56

Step-by-step explanation:

1:8= 7:?

1*?=7

/1   /1

1*7=7

8*7=56

1:8 = 7:56

Answer:

7:56

Step-by-step explanation:

1:8

we need to turn the one into seven. Turn the ratio 1:8 into the fraction 1/8.

multiply by 7/7 to turn the one into seven and 8 into 56

7/56 can now be turned into ratio 7:56. You could omit the turning of the ratio into the fraction at the beginning, but I find it makes it simpler.

t(x)=2x^2

Answers

Answer:

(s+t)(x) = s(x) + t(x)

(s*t)(x) = 2x³ + 4x²

Step-by-step explanation:

(s+t)(x) = s(x) + t(x)

= x + 2 + 2x²

= 2x² + x + 2

(s*t)(x) = s(x) * t(x)

= (x + 2) * 2x²

= 2x³ + 4x²
