Answer:

Infinitely many solutions

Step-by-step explanation:

we need to simplify the equations

1/5(20x-25)=4x-5

distribute the 1/5

4x-5=4x-5

+5 to each side

4x=4x

divide each side by 4

x=x

since x=x there are infinitely many solutions.

Answer:

no real solutions

Step-by-step explanation:

1/5(20x-25)=4x-5

1/5(20-25)=4-5

1/5(-5)=1

-1=1

Ok, first you need to read a - g and mark down the information you know. Also, this continuous function can look pretty much like anything long as it has the a - g constraints/rule. 

A) We know the domain(x values) is between -10 to infinity
(-10,-9,-8,-7,-6,-5,-4,-3-,2,-1,0,1,2,3,4,5,6,7,8,9,10, to ---------> infinity)
B) We know the range(y values) is between -6 to infinity
(-6,-5,-4,-3-,2,-1,01,2,3,4,5,6,7,8,9,10, to ---------> infinity) 

C) Next we know f(0) = f(4) = 0
So we know when x = 0  that f(0) = 0 or we can say  y = 0. We also know when f(4) = 0 so when x = 4 y = 0. So we have two points (0,0) and (4,0) that our function will be on so plot the two points (0,0) (4,0)

D) It tells us that f(x) (y) is increasing between the x values (-10,-6)  or (-2,2) or (4, to infinity)

E) It tells us that f(x) (y) is decreasing between the x values (-6,-2) or between (2,4)

F) Tells us that f(x) (y) is greater than or equal to between the x values of [-8,-4] or between the x values [0, to infinity) so this lets us know our drawing is going to be above or equal to 0 when we are in the values [-8,-4] or [0, to infinity)

G) Tells us that f(x) (y) is less than 0 when the function / drawing is between the x values of (-10, -8) or (-4,0)  

The picture is what the function could look like. It can be different but needs to following the rules that are given

Wrote the equation of the line that passes through (3,4) and (2,-1) in slope intercept form
nordsb [41]
So the equation of a line is y=mx + b.

In order to find the slope given only two coordinates we have to use a formula to find slope. It is:
y2-y1/x2-x1.

So let’s get all the values first from (3,4) and (2,-1).

y2= -1
y1=4
x2=2
x1=3
Plug in the values now.
-1 - 4 = -5
-5/2-3=5

The slope is 5x.

Now let’s find the y intercept, to find the y intercept, we have to do a formula which is:
y-y1=m(x-x1)
So let’s plug in the values.
y-4=5(x-3)
y-4=5x-15
+4 +4
y=5x-11

The final answer is y=5x-11!!!

Find the coordinates of the intersection of the diagonals of parallelogram qrst with vertices q(-8,1), r(2,1), s(4,-3), t(-6,-3)
TiliK225 [7]

Answer:

Point of intersection is (-2, -1).

Step-by-step explanation:

The diagonals bisect each other so we only need to find the midpoint  of one of the diagonals. We'll use the diagonal qs:-

Midpoint = (-8 + 4)/2, (1 + -3)/2

= (-2, -1)
