Answer: No, x+3 is not a factor of 2x^2-2x-12

========================================================

Explanation:

Let p(x) = 2x^2 - 2x - 12

If we divide p(x) over (x-k), then the remainder is p(k). I'm using the remainder theorem. A special case of the remainder theorem is that if p(k) = 0, then x-k is a factor of p(x).

Compare x+3 = x-(-3) to x-k to find that k = -3.

Plug x = -3 into the function

p(x) = 2x^2 - 2x - 12

p(-3) = 2(-3)^2 - 2(-3) - 12

p(-3) = 12

We don't get 0 as a result so x+3 is not a factor of p(x) = 2x^2 - 2x - 12

----------------------------------------

Let's see what happens when we factor p(x)

2x^2 - 2x - 12

2(x^2 - x - 6)

2(x - 3)(x + 2)

The factors here are 2, x-3 and x+2

Bisect means that the angles are split equally.

RTV would be half of RTS

RTV = 1/2(RTS)

16x-6 = 1/2(26x+18)

Simplify:

16x - 6 = 13x +9

Subtract 13x from both sides:

3x - 6 = 9

Add 6 to both sides:

3x = 15

Divide both sides by 3:

x = 5

Now you have x, replace x in the equation for RTV:

RTV = 16x -6 = 16(5) -6 = 80 - 6 = 74

RTV = 74 degrees.

Answer:

40 feets

Step-by-step explanation:

Given that :

Observer's height = 5 feets

Observer's distance from the mirror = 3 feets

Distance of tree away from the mirror = 24 feets

To obtain the height of tree:

Observer's distance (Od) / tree distance (Td) = Observer's height(Oh) / tree height (Th)

Od / Td = Oh / Th

3 / 24 = 5 / Th

3 * Th = 24 * 5

Th = 120 / 3

Th = 40 feets

Hence, the height of tree is 40 feets

Step-by-step explanation:

Time taken to earn $385 = 35 hours

Time taken to earn $1 = [tex] \sf \dfrac{35}{385} [/tex] hours

[tex] \sf = \dfrac{1}{11} \ hours [/tex]

Time taken to earn $143 = [tex] \sf \dfrac{1}{11} \times 143 [/tex] hours

[tex] \sf = 13 \ hours [/tex]

x=2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

b. The total sum of the money was $330

Step-by-step explanation:

#b

∵ A sum of money is divided among John, Paul, and Robert

∵ The ratio of the shares of John, Paul, and Robert is 2: 4: 5

→ Multiply the ratio of each share by x

∴ The share of John = 2x

∴ The share of Paul = 4x

∴ The share of Robert = 5x

→ Find their sum

∴ The sum of the money = 2x + 4x + 5x = 11x

∵ The sum of the money is divided equally among them

→ That means dividing the sum by 3 to find the share of every one

∵ The sum of the money = 11x

∴ The share of every one = [tex]\frac{11x}{3}[/tex] = [tex]\frac{11}{3}[/tex]x

∴ The share of John is larger by $50

→ That means the difference between his shares is 50

∵ [tex]\frac{11}{3}[/tex]x - 2x = 50

∴ [tex]\frac{5}{3}[/tex]x = 50

→ Divide both sides by [tex]\frac{5}{3}[/tex]

∴ x = 30

→ Substitute it in the sum of the money to find it

∵ The sum of the money = 11(30)

∴ The sum of the money = $330

∴ The total sum of the money is $330

Answer:

≈0.68

Answer:

Each property is mentioned with the corresponding expression.

Step-by-step explanation:

Writing the property in front of every expression:

1. Additive Identity: 11+0 = 11

2. Associative Property of Multiplication: x*(y*z) = (x*y)*z

3. Additive Identity: 8+(-8) = 0

4. Commutative property of Addition: 14+20=20+14

5. Multiplicative Inverse: 2*1/2 = 1

6. Multiplicative Identity : 22*1 = 22

7. Associative Property of Addition: (19+12)+8=19+(12+8)

8. Commutative Property of Multiplication: a*9=9*a

9. Distributive Property: 7(4+11) = 7(4)+7(11)

Answer:

5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)

Step-by-step explanation:

Let's find out how much each tractor can plow each hour.

[tex]\frac{600^{2} }{3*2}=60,000m^{2}[/tex] per tractor per hour

[tex]1,000^{2}=1,000,000m^{2}[/tex] is the area of the field of side length 1,000 meters

5 tractors can plow [tex]300,000m^{2}[/tex] per hour.

[tex]\frac{1,000,000}{300,000}=3.33[/tex] hours

Answer:

4.99 ft/sec

Step-by-step explanation:

1 mile = 5280 feet

3.4 miles = 17952 feet              or           (3.4 x 5280= 17952)

1 hour = 3600 seconds        (60 minutes per hour x 60 seconds per minute)

17952 feet / 3600 seconds = 4.99 feet per second

Answer:

The slope is 3/4 and the y-intercept is -5.

Step-by-step explanation:

Your equation is already in slope-intercept form, so all you have to do is look at it. Slope-intercept form looks like y = mx + b, where m is the slope and b is the y-intercept. Hope that helps!

Answer:

6x + 5y + 13 = 0.

Step-by-step explanation:

y = 5/6x + 7/6

Gradient = 5/6

Since the line is perpendicular to y = 5/6x + 7/6

then its gradient is -6/5.

Hence its equation is: point (-8,7).

y - 7 = -6/5(x -(-8))

multiplying through by 5 we get;

5y - 35 = -6(x + 8)

5y - 35 = -6x - 48

6x + 5y + 13 = 0
