Mathematics
2 answers:
Leni [432]3 years ago
6 0

a)X + Y = 20

b) X * Y = 36

Isolate Y in a: X= 20 - Y

Plug into b: (20-Y) * Y=36

20 Y - Y^2 = 36

0 = Y^2 - 20Y + 36

0 = (Y -18)(Y-2)

Y-18= 0, Y=18

Y-2= 0, Y= 2

Final answer: 2 and 18

Hope it’s clear :)

Explain how to find 27% of 16 using multiplication by
just olya [345]

Answer:

4.32

Step-by-step explanation:

You can multiply 16 by 0.27 to get the answer.

16*0.27=4.32

You can check your work with estimation because 27% is about 1/4 of the number, and just by looking at the number, 4 is 1/4 of the number.

This is some bull help
slamgirl [31]

To find y you need to insert x into the equation. The equation is y=2x+2, so insert the x on the table to find the y.

y=2(-4)+2=-6

y=2(-2)+2=-2

y=2(0)+2=2

y=2(1)+2=4

y=2(3)+2=8

These follow the equation's rule so it is correct.

Two plot the values of x and y you need to put it in (x,y) then plot it. Then you can check it by using the equation, y=mx+b, the b is the y intercept, so check to see if it starts there, and then check and see if it followings the slope

(-4, -6), (-2, -2), (0, 2), (1, 4), (3, 8)

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

Tickets to a sporting event cost $125 each. What's a reasonable domain and range.
djverab [1.8K]

The domain and the range of a function is the set of input and output values of the function.

The domain is the set of all whole numbers.

The range is the set of all whole numbers.

Let the number of tickets be x, and the revenue be y.

So, the revenue function will be:

y = 125

The number of tickets cannot be less than 0.

So, the domain of the revenue function is

domain=0,∞

The above means that, the domain is the set of all whole numbers

Similarly, the revenue cannot be less than 0.

So, the range of the revenue function is

range = 0,∞

The above means that, the range is also the set of all whole numbers (in multiples of 125).

The proper height of a highway guardrail is 27 inches, but 3 inches higher or lower is acceptable. Which inequality represents t
andriy [413]

Answer:

Step-by-step explanation:

27 is the "center" of a range of measurements of the height of the guard rail.  The height could be as much as 30 inches or as little as 24 inches.  The absolute value operator encloses "x - 27," where 27 is the "center."  The acceptable excess or acceptable deficiency is 3 inches.  

So now we can eliminate possible answers B and C, in both cases because 27 is inappropriately greater than 3.

Narrowing down our choices, we have h + 27 and h - 27 inside the absolute value operator.  27 is a positive quantity (height of the guard rail), so the inequality showing +27 as the "center" is correct; that is

D:  |h - 27| ≤ 3 (measurements in inches).
