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

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 answer should be $30.

Answer:

30 * t

Step-by-step explanation:

The garden club earned $15 per hour by weeding neighborhood gardens for t hours.

A generous donor has agreed to double their earnings.

Double their earnings means we multiply by 2

So earning 15 per hour becomes 2*15 = 30 per hour

Given the number of hours is t

Earnings = $30 times number of hours

Earnings = 30 * t

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:

[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.

Hope this helps.

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:

2/4 = 1/2

Step-by-step explanation:

slope = rise / run

rise = 2

run = 4

thus slope = 2/4 = 1/2

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^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

Step-by-step explanation:

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.

Step-by-step explanation:

7x-4+3x+14=180°

10x+10=180

10x=180-10

10x=170

x=170

10

x=17

hope it helps.

Answer: x = 17

Step-by-step explanation:

Alternate interior angles add up to 180°

3x + 14 + 7x - 4 = 180°

Combine like terms

10x + 10 = 180

Subtract 10 from both sides

10x = 170

Divide both sides by 10

x = 17

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:

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:

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
