Answer: A

Step-by-step explanation:

f(x)=3x-7\\g(x)=2x^2

(f-g)(x)=3x-7-(2x^2)\\(f-g)(x)=3x-7-2x^2\\(f-g)(x)=-2x^2+3x-7

Point U has Coordinates (-5,1) and point V has coordinates (7,9) find the coordinates of the midpoint of UV
frutty [35]

The mid point of the given  Coordinates U= (-5,1) and point V = (7,9):

= ( -6 , 5).

Midpoint of a Line Segment:

A line segment's midpoint is a point that divides the line segment across two equal sections. The midpoint of a line segment with coordinates at both ends X₁ , Y₁ and  X₂, Y₂ is calculated using:

<h3>According to the given data:</h3>

Point U has Coordinates (-5,1).

point V has coordinates (7,9).

Find  coordinates of the midpoint of UV = ?

We know that to find Midpoint of a Line Segment:

                               = \left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

Where U

           X₁ = -5

           Y₁ = 1

Whare V

           X₂ = 7

           Y₂ = 9

Putting the value in the formula:

UV = \left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

       = (-5 + 7)/2 , (1 + 9)/2

       = -6 , 5

The mid point of the given  Coordinates U= (-5,1) and point V = (7,9):

= ( -6 , 5).

The area ofa rhombus is 240 cm and one of the diagonals is 16 cm. Find<br> diagonal
stich3 [128]

Answer:

measure of other diagonal is 30cm

Step-by-step explanation:

let the other diagonal be d .

  • area of rhombus = 1/2 × 16 × d
  • 240 = 8 × d
  • d = 240 / 8
  • d = 30

hence the other diagonal = d = 30 cm

Will and tommie bought a giant candy bar composed of 24 pieces. Will ate 1/4 of the bar and Tommie ate 2/3 of the bar. How many
hichkok12 [17]

Answer:

3/24 or 1/8

Step-by-step explanation:

1. convert 1/4 and 2/3 into fractions with common denominators of 24 (since there are 24 pieces.

2. find the multiples of 4 and 3

    4, 8, 12, 16, 20, 24  = 5

    3, 6, 9, 12, 15, 18, 21, 24 = 8

3. convert the fractions

    1/4 * 5/5 = 5/24

    2/3*8/8 = 16/24

4. add the fractions.

    5/24 + 16/24 = 21/24

5. subtract 21/24 from 24/24 = 3/24

6. reduce by dividing both terms by 3 = 1/8

Can someone help me with 1 2 3 and 4 i have to find the slope for each line
Hoochie [10]

Answer:

1) -1/3

2) 4

3) 5/2

4) 5/7

Step-by-step explanation:

To find slope, you must do rise/run, where rise is movement up and down, and run is movement left and right.

So just start from the left most point and count the little unit squares up or down to determine rise and then count them left or right to determine run, do this until you get to the next point. (If it's a positive slope then the line will go up to the right, and if it's negative then it will go down to the right).

For example: In the first graph, since the line is going down, the slope is negative. As you can see it goes down 1 and over to the right 3, so that's why it's presented as -1/3.

Hope this helps :)
