Answer:
<em>The options are not visible enough (See Explanation)</em>
Step-by-step explanation:
Given
x:- 1 || 2 || 3 || 4 || 5
y:- 13 || 22 || 37 || 58 || 85
Required
Determine if the function is quadratic
Calculate the difference between the values of y
<em>The resulting difference are: 9 || 15 || 21 || 27</em>
Next; Calculate the difference between the difference of values of y
<em>The resulting difference are: 6 || 6 || 6</em>
<em>For the function to be quadratic, the above difference must be the same and since they are the same (6), then the function represents a quadratic function.</em>
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
Answer:
a. 150
b. y=150x+1200
Step-by-step explanation:
a. 1350-1200=150
b. if he opened it in 2005 he started his tutoring fee at 1200 that makes 1200 the y intercept
Answer: There are 667 owls for every 1000 squirrels.
Step-by-step explanation:
Since we have given that
Number of owls = 30
Number of squirrels = 45
If the number of owls and squirrels will continue to increase.
If there are 1000 squirrels, then the number of owls would be
Hence, there are 667 owls for every 1000 squirrels.
