Answer:
Step-by-step explanation:
The domain will be 0<x<6 and the range will be 0<y<72.
<h3>How to illustrate the information?</h3>
The information given implies that this would be a continuous relationship.
The process of elimination can be used to rule out the sets of numbers that are used in discrete relationships.
X is the amount of days that he was studying the plants.
The inequality is written like this for x: 0<x<6.
For the range, y is the plant food that was used which is 72 milliliters.

Answer:
5192.3 rounded off to nearest ten
Step-by-step explanation:
We get the number:
- 5190
- 3 dropped as a decimal fraction smaller than 1
- 2 dropped and replaced with zero as we round of to ten
- kids missed to replace 2 with zero and lost unit digits by doing that

Answer:
x = -5
, y = 0
Step-by-step explanation:
Solve the following system:
{4 x + 7 y = -20 | (equation 1)
2 x - 5 y = -10 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 7 y = -20 | (equation 1)
0 x - (17 y)/2 = 0 | (equation 2)
Multiply equation 2 by 2/17:
{4 x + 7 y = -20 | (equation 1)
0 x - y = 0 | (equation 2)
Multiply equation 2 by -1:
{4 x + 7 y = -20 | (equation 1)
0 x+y = 0 | (equation 2)
Subtract 7 × (equation 2) from equation 1:
{4 x+0 y = -20 | (equation 1)
0 x+y = 0 | (equation 2)
Divide equation 1 by 4:
{x+0 y = -5 | (equation 1)
0 x+y = 0 | (equation 2)
Collect results:
Answer: {x = -5
, y = 0
The perimeter is the sum of all the sides so we can add all the sides and set it equal to 35:
Now we have a quadratic so we can use the quadratic formula to find x=
. Now you can plug that into each x to find each side:-)
