Mrs. Miner has a coupon for a 30 percent discount on any electronic item. she wants to buy an Xbox one s. The original amount of the item is $250. How much will she pay if she uses the 30 percent off coupon A. $75.00 B. $175.00 C. $220.00 D. $325.00 HELP ASAP I WILL GIVE OUT BRAINLYIST
Answer:
B. $175.00
Step-by-step explanation:
Since the coupon is 30% off, to find how much it costs after the coupon, use the opposite: 70%
Which equals 0.7
Multiply that by 250:
250 × 0.7 = 175
So the answer will be $175.00

what is 5/6 x 3 in fraction form?
Answer:
The answer is 5/2
Step-by-step explanation:
5/6 times 3
15/6=
5/2
The fraction form of (5/6)×3 after simplification is 5/2.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, (5/6)×3.
= (5/6)×(3/1).
Now in fraction multiplication, we simply multiply the numerator with the numerator and the denominator with the denominator.
= (5×3)/(6×1).

Help!Write the equation in slope- intercept form of the line that passes through (−1, 11) and is parallel to the graph of y = −8x − 2
Answer:
y = -8x + 3
Step-by-step explanation:
plug in the point and the slope into the slope intercept formula (y=mx+b)
the slope will be the same since you want the line to be parallel
11 = -8(-1) +b now solve for b
11 = 8 + b
-8 -8
3 = b
now write the equation with only the slope and the y intercept
y = -8x + 3
The equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.
What is the slope intercept form of a line?The slope intercept form of a line is given by -
y = mx + c
m is the slope of line
c is the y - intercept
Given is a line that passes through (-1, 11) and is parallel to the line -
y = − 8x − 2.
Since, the line is parallel to the line → y = − 8x − 2, therefore, their slope will be same and is equal to m = - 8.
Now, in the slope intercept form, assume that the equation of line looks like -
y = - 8x + c
Now, the line passes through the point (-1, 11), we can write -
11 = -8 x -1 + c
11 - 8 = c
c = 3
Hence, we can write the equation of the line as -
y = - 8x + 3
Therefore, the equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.

What is the slope of the line parallel to y=2/5x-1?
I really need help with this fast please
Answer:
The slope will be 2/5.
Step-by-step explanation:
[tex]y = 2/5x -1[/tex] is written in slope-intercept form.
This formula looks like:
[tex]y=mx+b[/tex]
where:
M = Slope x = independent variableb = y-interceptSo:
[tex]2/5[/tex] is our slope[tex]x[/tex] remains our independent variable[tex]-1[/tex] is our y-intercept.1 ). For two lines to be parallel they must have the same slope.
Slope would remain 2/52 ). For two line to be perpendicular they must have slopes that are opposite reciprocals.
. Slope would become -5/2As the question states, we must find the slope of a line parallel to the equation given. This means that the slope will remain 2/5.
Lets check our work!
Choose a random ordered pair. I will choose (5, 6).
Now, using point slope-form we can find out if what was said above is true!
This formula looks like:
[tex]y - y1 = m (x-x1)[/tex]
Let us substitute:
[tex]y - 6 = 2/5(x-5)[/tex]
Distribute:
[tex]y-6=2/5x-2[/tex]
Add 6 to both sides:
[tex]y= 2/5x+4[/tex]
Now using both equations I will plot them on a graph to see if they a parallel.
As you can see from the graph below, these lines are parallel. Where the equation you were given is in blue and the equation I made is in red.
Based on all of the evidence, the slope will be 2/5.
Hope this helped! :)
