Answer:
y=17/3
Step-by-step explanation:
So you should make one -3y positive to cancel them out.
So multiply 2x-3y=43 by -1 and you get
-2x+3y=43
4x-3y=83
now +3y -3y cancel each other out
4x-2x=83-43
2x=50
x=25
Now enter 25 into the equation as x to find y
4(25)-3y=83
100-3y=83
100-83=3y
3y=17
y=17/3
Hey there!
First, find the slope of the actual original pair of points.
The slope formula is:
So now, substitute the points in, whichever order you substitute the points into the equation doesn't matter, as long as the ones substituted in with the same subscript number.
\
Once you subtract, you get:
So the slope is 11/10.
A line that is parallel to another has the exact same slope that that another line has.
So therefore the line that is
parallel has a slope of 11/10.
Perpendicular is another story. You take the reciprocal of the slope of the other line, and then change the sign before it: ex: negative would become positive.
So therefore the line that is
perpendicular has a slope of -10/11.
0.40x + 55 = 0.15x + 80
0.40x - 0.15x = 80 - 55
0.25x = 25
x = 25 / 0.25
x = 100 minutes <=
Answer: 6w^3 - 16w^7
Explanation:
2w^3(3 - 8w^4)
= 6w^3 - 16w^7
Answer:
discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions. Hope its Helps:):)
Step-by-step explanation:
Given : he quadratic equation −1 = 5x² −2x.
To find : What is the value of the discriminant .
Solution : We have given that −1 = 5x² −2x.
−1 = 5x² −2x.
On adding by 1 both sides
0 = 5x² −2x +1
On switching sides
5x² −2x +1 = 0
Compare it standard form of quadratic equation ax² +bx +c = 0.
Here, a = 5, b= -2, c = 1
By Discriminant formula:
D =
Substituting the values
D = .
D = 4 - 20
D = -16.
Therefore, discriminant of the quadratic equation is -16, The resulting number is less than zero so there are no real number solutions.
