Explain why the equation 5z+2=5z has no solution

2 answers:

6 0

Minus 5z from both sides
2=0
false
there is no solution because no matter what value you choose for z, they will cancel out and you will be left with
2=0

Subtracting 5z from both sides leaves 2=0, with this there is no solution...hope this helped :)

Which statement best describes the effect on the graph of y = (x – 9)2 if the equation is changed to y = (x + 9)2? The graph mov

alexandr402 [8]

Answer:

Third option: The graph moves left 18 units.

Step-by-step explanation:

Some transformations for a function f(x) are shown below:

If $f(x)+k$ , the function is shifted up "k" units.

If $f(x)-k$ , the function is shifted down "k" units.

If $f(x+k)$ , the function is shifted left "k" units.

If $f(x-k)$ , the function is shifted right "k" units.

In this case, we can observe that graph of $y = (x - 9)^2$ is changed to $y = (x + 9)^2$

Since:

$-9+18=9$

We can conclude that the function $y = (x - 9)^2$ is shifted left 18 units to get the function $y = (x + 9)^2$ .

Part A: A highway's path can be found using the equation 2x - 3y = 21. Use the graphs of the functions to determine the number o

EastWind [94]

Answer:

Step-by-step explanation:

Part A

2x-3y =21 in slope-intercept form is y=2/3x-7 one you graph the equation it would be a parallel to the equation shown above so there are no intersections

PART B

y=1/3x^2 and y= 2/3x - 5

1/3x^2 = 2/3x-5

1/3x^2=2/3x-5

then u multiply everything by 3

1/3x^2*3 =2/3x *3-5*3

the three for 1/3*3 cancels out so you are left with

1x^2= 2x -15

1x^2-2x+15=0

You can not factor it and well i guess there is no intersection

im sorry if i got this wrong bc i had a similar question just different numbers and i tried to solve this one the way i sloved mine so im not sure of my answer for part b

Three of the vertices of a trapezoid are A(3,-3), B(12, 6) and C(4,8). The fourth vertex is labeled D. One of its bases is AB

miskamm [114]

Answer:

y = x + 4

I graphed all the points, and the line that goes through AB is y = x - 6. The bases of a trapezoid are parallel, so the slope on the line CD has to be the same. I graphed the point C and just tried different y-intercepts to see which line would go through C.
