system, Jun determines that the value of y is
- a negative fraction only
- a positive fraction only
- a negative integer
- a positive integer

Answer:

trapezoid

Step-by-step explanation:

y = 4x     slope = 4

y' = 4x -16   slope = 4

TA // OM

TA: -1 ≤ x ≤ 0   (limited value)

OM: 3 ≤ x ≤ 5

TA and OM limited in different range, their length is not equal

The shape is a trapezoid

Answer:

B - The values of both x and y will be real numbers greater than or equal to 0.

The answer choice that best describes the values of x and y is B - The values of both x and y will be real numbers greater than or equal to 0.

Given that peaches are being sold for $2 per lb.

If we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:

y = $2*x

Therefore, the best description of the values of x and y is found in option B. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

28

Step-by-step explanation:

find 35% off 80 cakes

35% * 80

Converting percent to decimal:

35%/100 = 0.35

0.35 * 80

28

Therefore the baker sold 28 cakes out of the 80 cakes she baked. Hope this helps!

I think 35% of 80 is 28.

Answer:

Noah answer is the correct answer

Step-by-step explanation:

The solution to the above question is given as:

Total Volume = Volume of the prism + Volume of the cube

Volume of the prism = 20 cubic units

Volume of a cube = (Side length)³

= 10³ = 1000 cubic units

Hence: The total volume =

20 cubic units + 1000 cubic units

= 1,020 cubic units

Therefore, I agree with Noah's answer.

Answer:

The plane can fly 760 miles in 4/3 hours.

Step-by-step explanation:

Given that:

An airplane can cruise at 570 miles per hour.

We have to find the distance travelled by train in 4/3 hours.

Distance = Speed * Time

Distance = [tex]570*\frac{4}{3}[/tex]

Distance = [tex]\frac{2280}{3}[/tex]

Distance = 760 miles

Hence,

The plane can fly 760 miles in 4/3 hours.

Answer:

x^2+4x-32=0

(mid-term breaking---4 x 8=32)

x^2+8x-4x-32=0

x(x+8)-4(x+8)

x+8=0 or x-4=0

So x=+4 or x=-8

Answer:

BQ = 16

QE = 8

Step-by-step explanation:

Centroid of a triangle divides the median in the ratio 2 : 1

Here, let BQ = 2x and QE = x

BQ + QE = BE

2x + x = 24

3x = 24

x = 24/3

x = 8

2x = 2*8 = 16

BQ = 16

QE = 8

Answer:

The expression is given as:

Total amount = 8 + 2x

Total amount = $20

Step-by-step explanation:

Let the number of rides Elizabeth goes on be represented by x

The expression used to find the total amount =

$8 + $2 × x

= 8 +2x

Elizabeth goes on 6 rides

Total amount =

8 + 2 × 6

= 8 + 12

= $20

Answer:

  152 feet

Step-by-step explanation:

A triangle modeling the situation has the unknown length as its hypotenuse, and the given platform height as the side opposite the angle. The relevant trig function is ...

  Sin = Opposite/Hypotenuse

  sin(30°) = (76 feet)/(escalator length)

  escalator length = (76 feet)/sin(30°) = (76/0.5) feet

  escalator length = 152 feet

Answer:

24 cm

Step-by-step explanation:

We can set up a ratio of 18 m / x cm = 3 m / 4 cm because we know that it's a scale.

Cross multiplying, we get 3x = 72. Divide both sides by 3 and we have x = 24 cm.

We can also consider it by just dividing 18 m by 3 m to find the scale factor, which is 6. We then multiply the 4 cm by 6 to get 24 cm as well.

Answer:

Step-by-step explanation:

The figure is a parallelogram, so ...

  AB ≅ DC = 16

Opposite angles are congruent, so ...

  ∠DAB ≅ ∠DCB = 120°

The diagonals cross at their midpoints, so ...

  ED ≅ EB = 10.2

Adjacent angles in a parallelogram are supplementary, so ...

  180° -∠DAC = 180° -120° = ∠ADC = 60°

The sum of angles in ∆ABD is 180°, so ...

  180° -120° -43° = ∠ABE = 17°

Answer:

[See Below]

Step-by-step explanation:

For 5 hours: f(5)

f(5) = 9(5) + 10

f(5) = 45 + 10

f(5) = 55

Bill would work earn $55 if he worked for 5 hours.

For 12 hours: f(12)

f(12) = 9(12) + 10

f(12) = 108 + 10

f(12) = 118

Bill would work earn $118 if he worked for 12 hours.

Answer:

x = 6

Step-by-step explanation:

Assuming the equation is

[tex]\frac{2x+3}{3}[/tex] - [tex]\frac{3x}{2}[/tex] = - 4

Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions

2(2x + 3) - 9x = - 24

4x + 6 - 9x = - 24

- 5x + 6 = - 24 ( subtract 6 from both sides )

- 5x = - 30 ( divide both sides by - 5 )

x = 6

Answer:

x=5

Step-by-step explanation:

If the sum of the measures of angle M and R is 90 degrees, and you know that angle R is 55 degrees, subtract angle R from the total angle. Then, solve for M

90 - 55 = 35

5x + 10 = 35

5x = 25

x = 5

Answer:

the answer is (4,6)

Step-by-step explanation:

Answer: x = -6

Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.

y = x - 6

y = 2x

2x = x - 6 (substitute the y value into the equation)

1x = -6 (subtract x on each side)

x = -6 (1x is basically saying x so you do not need to divide)

Answer:

f(-10) = -1/2

f(0) = -3

Step-by-step explanation:

Here, given the equation for f(x) we want to get the value of f(x) for each value of x supplied

We proceed as follows

f(-10) = 6/-10-2 = 6/-12 = -1/2

f(0) = 6/(0-2) = 6/-2 = -3
