Answer:

x = 2

Step-by-step explanation:

Since we know one root is -3, we know one factor of the equation is (x+3)

From there we can use the factor we know to factor the rest of the equation:

x^2 + x - 6 = (x+3) * ?

Since know -6 is just 3 * -2 and since 3-2 is 1,

(x+3)(x-2) = x^2 + x - 6

From there,

x - 2 = 0

x = 2

(2x - 20) = 20

(4x - 10) = 70

Answer:

first, simplify the equation, 5x-8x is -3x. So 6-7x = -3x+10

now subtract 6 from both sides, -7x = -3x+4

now add 3x on both sides. -4x = 4. now divide 4/-4 is -1. Thus X=-1

Answer:

x=-1

Step-by-step explanation:

6 - 7x = 5x - 8x + 10

First move the variables (x) to one side:

6 - 7x = 5x - 8x + 10

  +7x                +7x

6 = 5x - 8x + 7x + 10

Subtract 10 from both sides:

6 = 5x - 8x + 7x + 10

-10                           -10

-4 = 5x - 8x + 7x

Simplify:

4x = -4

Divide by 4 to isolate x:

4x = -4

÷4     ÷4

x=-1

Step-by-step explanation:

y = x² + x + 5

y = x + 1

x² + x + 5 = x + 1

x² + 4 = 0

x² = -4

x = ±√-4 undefined

Answer:

39

Step-by-step explanation:

6x6=36+3=39

Answer:

49

Step-by-step explanation:

<EDA + <ADC = 180 (half an angle)

So:

180 - 61 = 119 = <ADC

The interior angles of the quadrilateral add up to 360- we already know three of them, so:

73 + 119 + 119 + C = 180 ->

311 + C = 180 ->

C = 180 - 311 ->

C = 49

Answer:

a < -1

Step-by-step explanation:

    The question is asking what coefficient a could possibly be. By comparing the blue and red parabolas, it can be observed that the red parabola has been flipped and vertically stretched. Let's break this down.

    First, in order for the red parabola to mirror the blue parabola, it needs the opposite sign. The blue parabola's coefficient is positive. In order to mirror this, the red parabola's coefficient will need to be negative.

    Lastly, the red parabola has been stretched. In order for the red parabola to stretch, its coefficient has to be greater than 1.

    In conclusion, the red parabola needs to be negative and have a value greater than 1. Therefore, the answer is a < -1.

Answer:

Answer:   3024

Step-by-step explanation:  

4x3=12

12x6=72

72x6=432

432x7=3024

Answer:

Firstly, we are told that the value we are supposed to convert is "330 meters per second." When we see the word "per," we know that the unit should be divided.

So, really, the value is:

[tex]330\ \frac{meters}{second}[/tex]

Which can be abbreviated to:

[tex]\frac{330\ m}{1\ sec}[/tex]

We can scratch off the last two answers because they involve an x, and that is not our given value.

We can also eliminate the second answer because we are supposed to convert to kilometers, which is abbreviated by "km."

So, the answer is A or:

[tex](\frac{330\ m}{1\ sec})(\frac{1\ km}{1000\ m})[/tex]

The equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Speed is the rate of change of distance over time

The speed in meter per second is given as:

[tex]Speed =330m/sec[/tex]

To convert from meters to kilometers, we simply multiply the distance by 0.001.

So, we have:

[tex]Speed =\frac{330m}{sec} \times 0.001[/tex]

Express 0.001 as 1/1000

[tex]Speed =\frac{330m}{sec} \times \frac{1}{1000}[/tex]

Rewrite as:

[tex]Speed =\frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Hence, the equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Answer:

x=-7

Step-by-step explanation:

Answer:

x = -7

Step-by-step explanation:

1/6(2 + x) = -5/6

~Simplify left side

1/3 + 1/6x = -5/6

~Subtract 1/3 to both side

1/6x = -7/6

~Multiply 6 to both sides

x = -7

Step-by-step explanation:

-9y - 10 = x

x = -9y - 10

5x + 6y = -11

5(-9y - 10) + 6y = -11

-45y - 50 + 6y = -11

(-45 + 6)y = -11 + 50

-39y = 39

y = 39/-39

y = -1

x = -9y - 10

x = -9(-1) - 10

x = 9 - 10

x = -1

Answer:

[tex]1\frac{1}{2}[/tex]

Step-by-step explanation:

The first step to solving this problem is to convert these into improper fractions.

[tex]7\frac{2}{3} =\frac{21+2}{3}=\frac{23}{3}[/tex]

[tex]5\frac{1}{9} =\frac{45+1}{9}=\frac{46}{9}[/tex]

The second step is to determine the reciprocal of the second term.

Reciprocal of [tex]\frac{46}{9} =\frac{9}{46}[/tex]

The third step is to multiply the first term by the reciprocal of the second term.

[tex]\frac{23}{3}*\frac{9}{46}=\frac{207}{138}[/tex]

The fourth step is to reduce this fraction.

[tex]\frac{207}{138}=\frac{3(69)}{3(46)}=\frac{23(3)}{23(2)}=\frac{3}{2}=1\frac{1}{2}[/tex]

Answer:

1 1/2 or 3/2

Step-by-step explanation:

First you need to make your fractions improper.

7 times 3 + 2 = 23, so the fraction is 23/3

5 times 9 + 1 = 46, so the fraction is 46/9

Since this is division, flip the second fraction.

So instead of 46/9, it's now 9/46

Now you can multiply.

23/3 + 9/46 = 207/138

207/138 simplified is 3/2, or  1  1/2

Answer:

V = 268 cubic inches

Step-by-step explanation:

[tex]V = \frac{4}{3} \pi r^{3}[/tex]

[tex]V = \frac{4}{3} \pi (4^{3} )[/tex]

[tex]V =\frac{4}{3}\pi (64)[/tex]

V = 268.0825731

V = 268

The volume of the sphere with radius 4 inches is V = 268.08 inches³

A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere = ( 4/3 ) πr³

where r is the radius of the sphere

Given data ,

Let the radius of the sphere be r = 4 inches

Let the volume of the sphere be V

So , Volume of a Sphere = ( 4/3 ) πr³

Substituting the given value of the radius, r = 4 in, we get:

V = (4/3)π(4³)

V = (4/3)π(64)

V = 268.08 inches³

Hence , the equation that finds the volume of the sphere is

V = (4/3)πr³ = (4/3)π(4³) = 268.08 inches³

what is part 2?? ey? ;)

Step-by-step explanation:

Answer:

At the end of 4 years, your savings will have grown to $6,077.

Step-by-step explanation:

Answer:

D^2 = (x^2 + y^2) + z^2

and taking derivative of each term with respect to t or time, therefore:

2*D*dD/dt  =  2*x*dx/dt  + 2*y*dy/dt  + 0 (since z is constant)

divide by 2 on both sides,

D*dD/dt = x*dx/dt + y*dy/dt

Need to solve for D at t =0,  x (at t = 0) = 10 km,  y (at t = 0) = 15 km

at t =0,

D^2 =  c^2 + z^2 = (x^2 + y^2) + z^2  =  10^2 + 15^2 + 2^2  = 100 + 225 + 4  = 329

D = sqrt(329)

Therefore solving for dD/dt, which is the distance rate between the car and plane at t = 0

dD/dt = (x*dx/dt + y*dy/dt)/D  =  (10*190 + 15*60)/sqrt(329)  = (1900 + 900)/sqrt(329)

= 2800/sqrt(329) = 154.4 km/hr
