the value of y varies directly with x. when y = 7.5, x = 5. what is the value of y when x = 80?.

Answers

Answer:

120:80 = 3:2

The image of point (-2,3) under translation T'is
(3,-1). What is the image of point (4,2) under the
same translation?

Answers

Answer:

Step-by-step explanation:

REF: 060309a

ANS:

(9,−2)

(x,y)-->(x+5,y-4)

Transformation involves changing the position of a point.

The image of the translation is (9,-2).

The point is given as:

[tex]\mathbf{A= (-2,3)}[/tex]

The image of the point is:

[tex]\mathbf{A'= (3,-1)}[/tex]

The translation rule is calculated as:

[tex]\mathbf{T = <x + 3--2,y-1-3>}[/tex]

[tex]\mathbf{T = <x + 5,y-4>}[/tex]

So, the image of (4,2) is:

[tex]\mathbf{Image = (4 + 5, 2 -4)}[/tex]

[tex]\mathbf{Image = (9, -2)}[/tex]

Hence, the image of the translation is (9,-2).

Answer:

  A)  29/40

Step-by-step explanation:

The formula for this is ...

  P(A or B) = P(A) + P(B) - P(A and B)

Filling in the given values, you have ...

  P(A or B) = 9/20 +1/2 - 9/40

  P(A or B) = 18/40 +20/40 -9/40 = (18+20-9)/40

  P(A or B) = 29/40 . . . . matches choice A

What is the slope and y-intercept of x/3= -y+2 and how?????

Answers

subtract 2 from both sides

then you get -y equals 1/3x -2 so you have to flip the sign of the entire equation because you can’t have a negative line

so you get y = -1/3x + 2

the y-intercept is (0,2)

the slope is -1/3x (aka -x/3)

-5 2/3 + 3 1/4 + -7 1/3

PLEASE HELP!!! Find the slope of each side of the triangle.

Answers

9514 1404 393

Answer:

AB: -3BC: 2/3AC: -1/4

Step-by-step explanation:

The slope of a given segment is the ratio rise/run. The "rise" is the number of vertical divisions between the points. The "run" is the number of horizontal divisions between the points. The "run" is positive left-to-right. The corresponding "rise" is positive up.

Here are the segment slopes (rise/run).

  AB = -3/1 = -3

  BC = 2/3

  AC = -1/4

Tony bought 255 1-inch nails and 5 boxes of 2-inch nails. Each box of 2-inch nails had equal amounts of nails in them. He bought a total of 620 nails. Find the number of nails in each box of 2-inch nails.

Answers

Answer:

73 nails

Step-by-step explanation:

Number of 1 inch = 255

Boxes of 2 - inch = 5

Each box of 2 _inch has equal amount of nails

Total number of nails = 620

Number of nails in each box of 2_inch nails:

Let Number of nails in each box = b

Number of 1_inch + 5 * number of 2_inch = 620

255 + 5b = 620

5b = 620 - 255

5b = 365

5b / 5 = 365 / 5

b = 73

Hence, there are 73 nails in each box of 2_inch nails

Julio ​says, "If you subtract 13 from my number and multiply the difference by -3​, the result is -54 ​." What is Julios​'s ​number?

Answer:Julios​'s ​number is 31

suppose: Julios​'s ​number is x

because Julio ​says, "If you subtract 13 from my number and multiply the difference by -3​, the result is -54 ​"

=> we have: (x - 13).(-3) = -54

                 <=>  x  - 13 = (-54):(-3) = 18

                   <=> x = 18 + 13 = 31
