After 2014 the sales of new cell phones without cameras began declining. The number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240, where x is the number of years after 2014

Answer:

All real numbers

Step-by-step explanation:

Given: 10x-2-6x=2(2x-1)

Distribute: 10x-2-6x=4x-2

Simplify like terms: 4x-2=4x-2

Subtract 4x to both sides: -2=-2

Add 2 to both sides: 0=0

All real numbers

4g+4=2g+12

or , 4g-2g=12-4

or , 2g = 8

or, g=8/2

g= 2

x=0 I think not 100% sure though

Answer: The equation has infinitely many solutions.

Step-by-step explanation:

With George's end result of 3=3, you can assume that the equation is set up in such a way that no matter what you plug in, you will get the same number on both sides of the equals sign, which means the solution is valid. Therefore this means that there are an infinite number of solutions.

Answer:

See below

Step-by-step explanation:

I hope you wrote down the right equation using a minus sign instead of a plus.

Rounding 96.26 off to just 96  and then rounding 62.74 off to 62, you can subtract the two in your head real quick.

96 - 62 = 34

So using this estimation you can see that the answer of 159 is no where near correct.

Answer: 2/5

Explanation: Ask if you want an explanation!

      The question gives us two points, (-2, 1) and (8,5), from which we can find the slope and later the equation of the line.

Finding the Slope

The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)      

                                          =  (5 - 1) ÷ (8 - (-2))    

                                          =   ⁴/₁₀

                                          = ²/₅  

Checking my answer:

We can check to see if the answer is correct by drawing the line and seeing if it passes through both points. If it does, then the slope is correct.

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                                ⇒  y - 1 =  ²/₅ (x + 2)

In the graph below (created using Desmos), the line passes through both points. This suggests that we calculated the slope correctly.

Answer:

Slope = 2

Step-by-step explanation:

(1,3) and (3,7)

m = (7-3)/3-1)

= 4/2

= 2

Answer:

x = 128 degrees

Step-by-step explanation:

So we know that a triangle's interior angles should add up to 180 degrees.

We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.

With these clues, we can figure out that the last interior angle is equal to:

180 - (38+90) = 52, however this isn't the answer we are looking for.

We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:

180 - 52 = 128

x = 128

What is remainder R when the polynomial p(x) is divided by (2x - 1)? is (2x - 1) factor of p(x)?

p(x) = 2x² + 3x + 1

Answer :

R = 3

and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

∴ so the answer is option A

Answer:

y=3/2x+3/2

Step-by-step explanation:

point at (-6,-5)

slope = m = 3/2

y = mx+b

(-6)=(3/2)(-5)+b >>> substituting x & y to solve for b

-6 = (-15/2)+b >>> simplify previous equation

-6 + (15/2) = b >>> isolate and solve for m

3/2 = b

therefore, the equation of the line passing through the point (-6,-5) with a slope of 3/2 is y=(3/2)x+(3/2)
