Answer:

a.9

b. ay=9

xy= 18

Step-by-step explanation:

a. xa=ay (since a is a midpoint that means xa and ay are the same amount).

3x=5x-6

subtract 5x from both sides

-2x=-6

inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)

x=3

so xa=3x. fill in x

3*3 is 9

b. fill in the x

5*3-6

5 times 3 is 15.

15-6=9

(also xa is 9 and they are congruent so both are 9)

ay= 9

add both sides to find xy

9+9=18

xy=18

Answer:

FALSE
TRUE
TRUE

Step-by-step explanation:

1.

Non-standard units can be used to measure volume
Examples : m³, in³, cm³, mm³, L

2.

The volume of a rectangular prism can be found by multiplying the length, width, and height
V = lwh

3.

If there are smaller units, then naturally more of the units will be used
If there are larger units, then less of the units will be used

MODELING WITH MATHEMATICS A farmer plants a garden that contains corn and pumpkins. The total area (in square

laiz [17]

Answer:

The equation in standard form that models area of pumpkins is:

$A_p = A_G - A_c$

and the area is: $x^2+8x+2$

Step-by-step explanation:

Given that the garden has corn and pumpkins

The expressions are:

Total area of garden: $A_G = 2x^2+5x+4$

Area of Corn: $A_c = x^2-3x+2$

Area of Pumpkins: $A_p = ?$

The sum of areas of corn and pumpkins is the total area of the garden.

It can be expressed mathematically as:

$A_G = A_c+A_p$

If we have to find the area of pumpkins,

$A_p = A_G - A_c$

Putting the values

$A_p = (2x^2+5x+4) - (x^2-3x+2)\\A_p = 2x^2+5x+4-x^2+3x-2\\A_p = 2x^2-x^2+5x+3x+4-2\\A_p = x^2+8x+2$

The equation in standard form that models area of pumpkins is:

$A_p = A_G - A_c$

and the area is: $x^2+8x+2$

6) Triangle RST has vertices R(2,3), S(5. -1), and T(3, -4). The triangle is rotated 90° counterclockwise about the origin. Whic

Contact [7]

Answer:

T'(4, 3)

Step-by-step explanation:

The rule of 90° counterclockwise rotation about the origin:

(x, y) → (-y, x)

Apply the rule to the point T:

T(3, -4) → T'(4, 3)
