For the function f(x) = –5x, which ordered pair will be a point on the graph of the function? A. (–5, 1) B. (2, 10) C. (15, –3) D. (0, 0)

It's D: (0,0)
This is because when you put 0 in for x your y value will equal 0 and that is one of your answers, so it's the point (0,0)

(08.01)Consider the following system of equations: y = 5x + 6 y = −x − 7 Which description best describes the solution to the system of equations?

If you want an answer to question: You can make the equations equal to each other and solve for x. So, since the y values are the same, we can do 
(+x)5x+6 = -x-7. (+x)
(-6)6x+6= -7(-6)
  (1/6) x 6x= -13 x (1/6)
x= -13/6
Substitute −13/6 for x in y=5x+6:
y=5x(−13/6) + 6
y = -29/ 6.
y= -29/6  and x= -13/6

QUESTION POSTED AT 28/03/2020 - 12:33 PM

Anna adds (8x + 12y) and (ax − 6y). If the correct answer is 5x + 6y, what is the value of a? A) −3 B) −5 C) 13 D) 3

Answer:

A) -3

Step-by-step explanation:

Given,

When (8x + 12y) is added to (ax − 6y) the answer is (5x + 6y)

(8x+12y)+(ax-6y)=(5x+6y)

8x+12y+ax-6y=5x+6y

(8+a)x+6y = 5x+6y      ( By combining like terms )

By comparing,

8+a = 5

\implies a = 5 - 8 = -3

Hence, the value of x is -3,

Option A is correct.

What is the value of x? 5x = 16

To determine the value of x in our equation, "5x = 16", we need to divide both sides by 5 to get x by itself.
Divide 5 and 16 by 5.
5x/5 = x, 16/5 = 3.2.
x = 3.2

QUESTION POSTED AT 28/03/2020 - 11:21 AM

Someone please help me!? 4x-2y=16 4x-5x=8 Please enter answer as an ordered pair.

I'm assuming the 5x should be a 5y.

4x - 2y = 16
4x - 5y = 8

I would use the elimination method since the coefficients on the x variable are the same.
Subtract the second equation from the first equation.
  4x - 2y = 16
-(4x -5y = 8)
-------------------
       3y = 8
     y = 8/3
Plug */3 back in for y and solve for x.
4x -2y = 16
4x -2(8/3) = 16
4x - (16/3) = 16
add (16/3) to both sides.
4x = (16/3) + (48/3)
4x = (64/3)
multiply both sides by (1/4) to clear the 4
x = (64/3)(1/4)
x = 16/3
(16/3, 8/3)

→LM=18, NO=4, and LN=10.

Use angle bisector theorem

If a line bisects an angle, the ratio of two connecting sides with that angle which is bisected,is equal to ratio of the length of segments where the angle bisector is intersecting the third side.

\frac{NL}{LM}=\frac{NO}{OM}\\\\ \frac{10}{18}=\frac{4}{x}\\\\ 10 x=72 \\\\ x=7.2

Solve equation for 5x-14=8x+4

Remember, you can do anything to an equation as long as you do it to both sides


get 1 of the x on one side

5x-14=8x+4
minus 5x both sides (we want on left side because 8>5 and I like positive stuff)

5x-5x-14=8x-5x+4
0-14=3x+4
-14=3x+4
minus 4 both sides
-14-4=3x+4-4
-18=3x+0
-18=3x
divide both sides by 3
remember, negative/positive=negative
-18/3=(3x)/3
-6=x(3/3)

Solve the logarithmic equation. Be sure to reject any value that is not in the domain of the original logarithmic expressions. Give the exact answer. log6x2 = log6(5x + 36)

Answer:x=-4 or 9

Step-by-step explanation:

Given

log_{6}( x^2)=log_{6}(5x+36)

This log will be defined when

5x+36>0

x>-\frac{36}{5}

L.H.S=R.H.S

thus x^2=5x+36

x^2-5x-36=0

x^2-9x+4x-36=0

\left ( x+4\right )\left ( x-9\right )=0

thus x=-4 or 9

as these two values are in the domain therefore -4 & 9 are the solution of the Given system.

Ava's age is 5 years less than 4 times Amy's age. If Amy's age is x years, which expression best shows Ava's age? x x − 1 4x − 5 5x − 4

Answer:

Hi!

The correct answer is 4x-5.

Step-by-step explanation:

  1. X is the years of Amy.
  2. If you want to multiply by four the years of Amy, then you have 4X.
  3. If you want to substract five years at four the years of Amy, then you have 4X - 5.

Example:

Amy's age 20, so X = 20.

Ava's age is Y.

  • Y = 4X - 5
  • Y = 4*20 - 5 = 75.

The figure below shows the graph of f ', the derivative of the function f, on the closed interval from x = -2 to x = 6. The graph of the derivative has horizontal tangent lines at x = 2 and x = 4. Find the x-coordinate of each of the points of inflection of the graph of f. Justify your answer.

The inflection points are when acceleration is equal to zero.  If the above graph is dy/dx, acceleration will be equal to zero when the slope of it is zero because that will mean velocity is constant at that point.

So if the graph of dy/dx has horizontal slopes at x=2 and 4, they are the x-coordinates of the inflection points of f(x).
