Answer:

Step-by-step explanation:

The graph increasing over the given entire interval: -3 < x < 0.

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=2x+5. Where:

m= the slope.

b= the constant term that represents the y-intercept.

Here, we have,

For the given example: m=2 and b=5.

A function can be classified as:

  increasing - when the values of y increase with the increasing of x-values

  decreasing - when the values of y decrease with the increasing of x-values

The question gives the entire interval where the function increases. Thus, from the graph is possible to see that the function increases when x is between –3 and 0 because the values of y increase with the increasing of x-values.

Hence, The graph increasing over the given entire interval: -3 < x < 0.

The center of a circle lies on the line y=6x+2 and is tangent to the x-axis at (-2,0)

What is the equation of the circle in standard form?⇩

-Standard form for the equation of a circle is (x−h)2+(y−k)2=r2. The center is (h,k) and the radius measures r units. To graph a circle mark points r units up, down, left, and right from the center.

Answer:

251 = 130 + q

This is d equation

Answer:

251 = q + 130

Step-by-step explanation:

251 is equal to 130 added to q,

→ 251 = q + 130

Let's solve the equation,

→ 251 = q + 130

→ q = 251 - 130

→ [ q = 121 ]

So, the answer is 121.

Answer:

B

Step-by-step explanation:

Look at the expression inside the log( ).  Work from the outside in, so to speak.  First, there's a quotient (the cube root divided by 3x).

[tex]\log \left( \frac{\sqrt[3]{2-x}}{3x} \right) = \log\left(\sqrt[3]{2-x}}\right) - \log{3x}[/tex]

The cube root can be written using a rational exponent.

[tex]\log\left(\sqrt[3]{2-x}}\right) - \log{3x} = \log \left( (2-x)^{1/3} \right) - \log{3x}[/tex]

Use the exponent property to move the exponent 1/3 out.

[tex]\log (2-x)^{1/3} - \log{3x} = \frac{1}{3} \log{(2-x)} - \log{3x}[/tex]

This now matches answer choice B.

g(x) = -16^x + 8

Step-by-step explanation:

This reflection is accomplished by putting a negative sign in front of 16^x, and the upward translation by adding 8:

f(x)=16^x  becomes  g(x) = -16^x + 8

Answer:

I assume you are looking for the x and y values of the two equations? if not message me!

y=–2

x=1

Step-by-step explanation:

Multiply the first/top tearm by –3 so we can "get rid of" the X's with the addition of both equations. we are then left with: 14y=-28

We can now divide both sides by 14 to get y by itself so we are left with: y=–2

plugging our y value back into the first equation we get: 3x+8=11. we subtract 8 from both side and are left with: 3x=3. dividing both side by 3 we can get x by itself and are left with: x=1

To check, we plug x and y both into the first equation we get: 3+8=11 (which it does). Or we can plug both of them into the second equation and we get:9-4=5 (which it does)

Answer:

Below in bold.

Step-by-step explanation:

3x-4y=11

9x+2y=5

Multiply the first equation by 3:

9x - 12y = 33

Subtract the above from the second equation:

2y - (-12y) = 5 - 33

14y = -28

y = -2.

Now plug y = -2into the first equation:

3x - 4(-2) = 11

3x = 11 - 8 = 3

x= 1.

do parenthesis first

6(4x-3)-9x

24x -18 -9x

15x-18

The simplified expression after applying the distributive rule for the expression 6(4x - 3) - 9x becomes 15x - 18

The given expression is:

6(4x-3)-9x

Expanding the expression using the distributive rule

24x - 18 - 9x

Collect like terms

24x - 9x - 18 (since 24x and 9x are similar)

The resulting expression becomes:

15x - 18

x = price per video game

y = price per CD

164 = 5x + 3y

and then we know

x = y + 12

now we can use this as substitute in the first equation :

164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60

104 = 8y

y = $13

x = y + 12 = 13 + 12 = $25

so, each CD costs $13.

Answer:

r= -11

Step-by-step explanation:

11r + 60=16

we can see that 11x r + 60 = 16

but thats the problem ! we don't know what r is so

lets get r on its own

11r + 60 =16

subtract 60 from each side

60 -60 =0

left side = 11r

16-60 = -44

right side = -44

11 r = -11

divide both sides by 11

11r divided by 11 = r

-44 divided by 11 = -11

r=-11

Answer:   y = 2x, D.

Step-by-step explanation:  We can calculate the slope of the line between these two points:  Rise/Run:

Rise: (10-0)=10

Run:  (5-0) = 5

Rise/Run = 10/5 = 2

The y-intercept is zero (it is the value of y when x=0, which we are given as (0,0)).

The line between these two points is thus y=2x+0, or

y = 2x.  Looks like D.

Answer:

D. y=2x

Step-by-step explanation:

0x2=0 and 5x2=10. That's really it, simple math

Answer:

12

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 60-30)/(6-0)

   = 30/6 = 5

Now using a second set of points and the slope we can find p (0,30) and (p,90)

5 = ( y2-y1)/(x2-x1)

5 = (90-30)/(p-0)

5 = 60/p

Multiply each side by p

5p = 60

Divide by 5

p =60/5

p = 12
