Find the x-intercept(s) of the equation: y =3x^2-3x-6

a. x-intercepts: (-1,0) and (2,0)

b. x-intercepts:(0,-3) and (0,2)

c. x-intercept: (-6,0)

d. x-intercept: (0,-6)

Answer:

x = -3

Step-by-step explanation:

If the equation is correctly written as 15·x = -27 + 6·x

Then we have;

15·x = -27 + 6·x

We subtract 6·x from both sides to have all the variables (x) on one side as follows;

15·x - 6·x= -27 + 6·x - 6·x

Which gives;

x·(15 - 6) = -27 + x·(6 - 6)

We note that 6 - 6 = 0, therefore, we have;

x × 9 = -27 + x × 0

We not that x × 0 = 0, therefore;

x × 9 = -27

We now divide both sides with the 9 to get the value of x alone as follows;

x×9/9 = -27/9

Which gives;

x = -27/9 = -3

x = -3

Answer:

117°

Step-by-step explanation:

Arc ABC (AB + BC) is intercepted by angle D.

Therefore, Arc ABC is 2 × m<D. (Inscribed Angle Theorem)

AB = 91°

m<D = 104°

Let BC = x

Arc ABC = (91° + x)

Thus,

91° + x = 2 × 104°

Solve for x

91 + x = 208

Subtract 91 from both sides

91 + x - 91 = 208 - 91

x = 117

Measure of arc BC = 117°

Answer:

  70, 140, 280, 350

Step-by-step explanation:

Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.

Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...

So, the four smallest numbers with prime factors of 2, 5, and 7 are ...

  70 = 2·5·7

  140 = 2²·5·7

  280 = 2³·5·7

  350 = 2·5²·7

Answer:

I can't give a full answer because I can't see the image whilst giving an answer but I'll try so....

Step-by-step explanation:

Angles in a straight line add to 180° so when you have one of two of them angles are them together and take away from 180°

Angles around a full point add to 360° so add angles together and take away from 360°

On A I think it is you have a 360° angle and have to work out 3 and you have one already done and the opposite angle is the same as that so you basically have two angles then you add them together then take from 360 then divide the answer by two and then that would be the angles for a and x

And for the last one you have been given two angles with a right angle and a right angle equals 90 so add them together and take from 180 to get the missing angle

Answer:

(7x + 27) units

Step-by-step explanation:

A rectangle is a quadrilateral (has four sides) in which opposite sides are equal and parallel, also all the angles are equal. The area of a rectangle is given as:

Area = Length × Width

Given that the area of the rectangle is 21x + 81 and the width is 3 unit, to find the length of the rectangle, we have to use the formula of the area and then get the length. Therefore:

Area = Length × Width

21x + 81 = Length × 3

Length  = (21x + 81) /3

Length  = 7x + 27

The length of the rectangle is 7x + 27 units

Answer: g=-3

Step-by-step explanation: 2-4g=14

                                             -2       -2

                                              -4g=12

                                              -4g/-4=g 12/-4=-3

Answer:

g = -3

Step-by-step explanation:

2-4g=14

Subtract 2 from each side

2-2-4g=14-2

-4g = 12

Divide each side by -4

-4g/-4 = 12/-4

g = -3

Answer:

3rd option is correct

Step-by-step explanation:

If the table represents a function, that means that it is proportional. But the value increases and decreases, showing no proportional relationship.

So, the answer could be 1st or 3rd as they tell that the table doesn't represent a function.

1st answer says the table doesn't represent a function because the 2 (y-values) are similar;

Their x-values are different so, this answer is wrong.

3rd answer says that the table doesn't represent a function x-value increases, while y-value increases and decreases;

The statement is correct because it this table doesn't represent a proportional relationship as its y-values are increasing and decreasing while its x-values are only increasing.

So, the 3rd option is correct.

Answer:

[tex]\huge\boxed{x = -\frac{5}{6}}[/tex]

Step-by-step explanation:

[tex]f(x) = -12x+7[/tex]

Given that f(x) = 17

[tex]17 = -12x+7[/tex]

Subtracting 7 to both sides

[tex]17-7 = -12x[/tex]

10 =  -12 x

Dividing both sides by 12

[tex]x = - \frac{10}{12}[/tex]

[tex]x = -\frac{5}{6}[/tex]

Answer:

-5/6 =x

Step-by-step explanation:

f(x) = -12x+7

We want to find x when f(x) = 17

17 = -12x+7

Subtract 7 from each side

17-7 = -12x +7-7

10 = -12x

Divide each side by 12

10/-12 = -12x/-12

-5/6 =x

Answer:

2x - 10 = 44 + 8x

7x - 4 = 20 =3x

2(x-3) = -20

15 - 4x + 5 = 32

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*x-10-(44+8*x)=0

Pull out like factors :

  -6x - 54  =   -6 • (x + 9)

  -6   =  0

 Solve  :    x+9 = 0

Subtract  9  from both sides of the equation :

                     x = -9

x = -9

Move all terms containing

divide each term by 4

x = 6

2(x−3)=−20

Step 1: Simplify both sides of the equation.

2(x−3)=−20

2x−6=−20

Step 2: Add 6 to both sides.

2x−6+6=−20+6

2x=−14

Step 3: Divide both sides by 2.

x=−7

−4x+20=32

Answer:

x = 5

Step-by-step explanation:

The measure of an arc equals the measure of the central angle that intercepts it.

The measure of an arc intercepted by a diameter is 180 deg.

m(arc)EH = 180

m(arc)EF + m(arc)FG + m(arc)GH = m(arc)EH

10x + 8 + 67 + 11x = 180

21x + 75 = 180

21x = 105

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = [tex]\frac{x}{x-7}[/tex]

The denominator cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be.

solve

x - 7 = 0 ⇒ x = 7 ← excluded value

Thus

x = - 7 → in domain

x = 0 → in domain

x = 7 → not in domain

Answer:

-7= in domain

0= in domain

7= not in domain

Answer:

12

Step-by-step explanation:

(whole secant) x (external part) =    (whole secant) x (external part)

( 7+x+2) * 7 = ( 6+8) * 6

Combine like terms

(9+x) *7 = 14*6

Distribute

63 +7x = 84

Subtract 63

63 +7x -63 = 84-63

7x =21

Divide by 7

7x/7 = 21/7

x = 3

KM = x+2+7

      = 3+2+7

      =12

Answer:

[tex]\huge\boxed{KM = 11}[/tex]

Step-by-step explanation:

According to secant - secant theorem:

(MK)(ML) = (MR)(MN)

Where

MK = 7 + x+ 2 = x + 9

ML = 7

MR = 8 + 6 = 14

MN = 6

=> (x+9)(7)= (14)(6)

=> 7x + 63 = 84

Subtracting both sides by 63

=> 7x = 84 - 63

=> 7x = 21

Dividing both sides by 7

=> x = 3

Now,

KM = x + 9

KM = 3 + 9

KM = 11

Answer:

the window would be 72ft²

Step-by-step explanation:

A window is rectangular in shape.

the area of a rectangle is give as length * breadth

but this question say that the manufacturer wants to enlarge the window by 1.5

therefore we are going to multiply the length by 1.5 and the breadth also by 1.5 to get the new area of the bigger window.

length = 8 * 1.5

= 12

width = 4 * 1.5

= 6

The new area would be = l * b

= 12 * 6

= 72ft²

Answer:

$ 23,145

Step-by-step explanation:

This is a compound interest question where the interest is compounded continuously. Hence, the formula for the value of total amount of investment is:

A = P×e^rt

Where:

A = Total value of investment after t years

P = Principal or Initial amount invested = $6,000

e = Exponential function

r = interest rate = 9% = 0.09

t = time in years = 15

So:

A = $6000 × e^15 × 0.09

A = $6000 × e^1.35

A = $23,144.553184

Approximately , A ≈$23,145

Therefore, the value (in dollars) to the nearest cent of Rochelle's investment in 15 years if the investment is earning 9% per year and is compounded continuously is $23,145.

Answer:

5 feet

Step-by-step explanation:

Since Jackson's bedroom is a rectangle, it has dimensions of length times width. Suppose the length is l and the width is w.

The area of a rectangle is given by A = lw, where l is the length and w is the width. Here, we know the area is 90, so:

lw = 90

We also know that this area of 90 square feet is 9 times that of the closet, so suppose the area of the closet is c. Then:

9c = 90

Divide by 9:

c = 90/9 = 10 square feet

So, the area of the closet is 10 square feet. Since the width is 2, we know the length will be:

A = lw

10 = lw

10 = 2 * l

l = 10/2 = 5

The length is thus 5 feet.

~ an aesthetics lover

Answer:

5 ft

Step-by-step explanation:

If his bedroom is 9 times of his closet, then that means you divide the area of his bedroom by 9.  So, 90 divided by 9=10.  That means the closet has an area of 10 sq. ft.  As we all know, the area is the length times width.  So if the width is 2 ft, then we need to multiply it by a number so it will equal 10.  You can do 10 divided by 2 to find it, which equals 5.  That means the length of the closet is 5 sq. ft.
