Answer:
The product of two rationalnumber is (-20/40 ).If one ofthe number is (4/5), then the other number is -5/8
4/5*-5/8 = -20/40
x= the number
4*x/5 =-20/40
4x*40 = -20*5
160x=-100
x=-100/160 = -5/8
Answer:
Simplified expressions which represents the area of the floor of the conference room in square meters is:
3x²-13x+4
Step-by-step explanation:
A conference room is in the shape of a rectangle.
Its floor has a length of (x − 4) meters and a width of (3x − 1) meters.
we know that Area of rectangle=Length×Breath
Area of floor of the room=(x-4)(3x-1)
(x-4)(3x-1)=x(3x-1)-4(3x-1) (Distributive property)
= 3x²-x-12x+4 (Distributive property)
= 3x²-13x+4 (On combining the like terms)
Hence, simplified expressions which represents the area of the floor of the conference room in square meters is:
3x²-13x+4
y=-9/5x+3 ??
Answer:
sample response:
Step-by-step explanation:
Partial and negative tickets cannot be sold, so the minimum number values of e and s are 0. If s = 0, then e = 16, and if e = 0, then s = 20. Therefore, the values of s are whole numbers from 0 to 20 and the values of e are whole numbers between 0 and 16. The greatest number of student tickets sold was 20 and the greatest number of nonstudent tickets sold was 16.
To begin this problem, we need to use the two points that we are given to find the slope of the line. Slope is defined as the change in y values divided by the change in x values, or rise/run, and is represented by the variable m.
m = (y1-y2)/(x1-x2) = (8-0)/(3-6) = 8/(-3) = -8/3
Now, we can use the slope and one of the points from our given values to create an equation of the line in point-slope form.
y = m(x-h) + k, where a point on the line is (h,k)
y = -8/3(x - 3) + 8
Now, we can distribute our slope and simplify through addition.
y = -8/3x + 8 + 8
y = -8/3x + 16
Therefore, your answer is y = -8/3x + 16.
Hope this helps!
