Freddy reads an equal number of pages of a book every week. The graph below shows the number of pages of the book left to read, y, after x weeks:Which equation best models the relationship between x and y?

y = −5x + 40
y = −40x + 280
y = −40x + 200
y = −5x + 200

Answers

Wow, the only thing i can think of is that it gives you y and x, so you're basically plugging in the other numbers. So y = 200 and x = 5, and if you were to plug those numbers into each equation they give you, you would come up with 15, 80, 0, and 175. But you're trying to get y to equal 200, so the closest one is c. I'm sorry that's the only thing i can come up with. The rest just aren't close.

The linear equation that best models the relationship between x and y is y = -40x + 200.

What is the graph of a linear equation?

The graph of a linear equation is a straight line graph and the function of a linear equation assumes a slope-intercept form y = mx + b

where;

  • Slope = m
  • y-intercept = b

The slope = rise/run

From the graph, we need to rise 200 units to the origin and run 5 units to the horizontal positive axis.

So,

  • Slope = -200/5
  • Slope = -40

The y-intercept is the region at which the line cuts the vertical axis.

  • y-intercept = (0,200)

Now, putting it all together and using the slope-intercept form, the equation that best models the relationship between x and y is:

y = -40x + 200

Step-by-step explanation:

Two equations are given below:a – 3b = 16
a = b – 2

What is the solution to the set of equations in the form (a, b)? (5 points)


(–2, –6)
(–7, –9)
(–11, –9)
(–12, –10)

Answers

Asking the Math Gods...


a=-11
b=-9
Since a = b - 2, we can substitute this value into the other equation to find the value of b.  Once we have a value for b, we substitute it back into one of the equations to find the value for a.

a - 3b = 16
b - 2 - 3b = 16
-2 - 2b = 16
-2b = 18
b = -9

Now substitute back into the equation

a = b - 2
a = -9 - 2
a = -11

Solution set in the form (a, b) is...

(-11, -9)

Prove:
sin^2x (sec^2x + csc^2x)=sec^2x

Answers

sin^2x (sec^2x + csc^2x) = sec^2x

I would convert the functions in the parentheses to their reciprocals.

sin^2x (1/cos^2x + 1/sin^2x) = sec^2x

Now distribute the sine.

sin^2x/cos^2x + sin^2x/sin^2x = sec^2x

Remember that sine divided by cosine is always tangent.

tan^2x + sin^2x/sin^2x = sec^2x

The remaining fraction is simply 1.

tan^2x + 1 = sec^2x

Use the Pythagorean identity to add the left side.

sec^2x = sec^2x
