Please help me sole this equation !!

Answers

Answer 1

Answer: $(9x - 15)/(4) = x$ / * 4 (both sides)
9x - 15 = 4x / - 9x (both sides)
-15 = -5x / ÷ (-5) (both sides)
x = 3

Answer 2

Answer: (9x-15)/4=x /*4...... 9x-15=4x........ 5x=15........ x=3

The graph shows the functions f(x), p(x), and g(x):Part A: What is the solution to the pair of equations represented by p(x) and f(x)?

Part B: Write any two solutions for f(x).

Part C: What is the solution to the equation p(x) = g(x)? Justify your answer.

Answers

The function f(x) is:

f(x)=x

This is because the line f(x) passes through the points (-1,-1), (0,0), (1,1) etc.

The function p(x) is:

p(x)=mx+C

Whereby (m) is the slope and (C) is a constant.

m=-4/3, as m=tan(ω)=O/A=-4/3 as slope is negative.

Now when y=-3, x=-3.

So:

-3=-4/3 *(-3) +C

-3= 4 + C

C=-7

This means that:

p(x)=-4/3x -7

Now, where p(x)=g(x), x=-6.

p(-6)=-4/3 * (-6) -7

p(-6)=24/3 -7

p(-6)=8-7

p(-6)=1

Therefore:

p(x) and g(x) meet at (-6, 1) and the solution to p(x)=g(x) is x=-6.

What is the radius of a circle with center (2,1) and containing point (0,1)

Answers

Answer:

The radius is 2 or The simplified radius is 4 ( if needed).

Step-by-step explanation:

- The equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$ where the center is $(h,k)$ , the point as $(x,y)$ and the radius $r^2$ .

-Put both the center and the point onto that equation:

$(0-2)^2+(1-1)^2=r^2$

-Then, solve them up:

$(0-2)^2+(1-1)^2 =r^2$

$(-2)^2+0=r^2$

$4 + 0=r^2$

$4 = r^2$

$√(4) =√(r^2)$

$2=r$

A similarity transformation maps polygon ABCD to polygon PQRS. If the length of is 6 and the length of the corresponding side, , is 12, what is the scale factor of dilation

Answers

For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:
$k = (L1)/(L2)$
Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:
$k = (6)/(12)$
Rewriting we have:
$k = (1)/(2)$
Answer:
The scale factor of dilation is given by:
$k = (1)/(2)$

$(6)/(12)$ = $(1)/(2)$ from the larger polygon to smaller one

$(12)/(6)$ = 2, from the smaller polygon to the larger one.
