Answer:
$18
Step-by-step explanation:
Given:
y = 0.9x - 4.5
Where,
x = age in years
y = hourly pay in dollars
what is the best prediction for the hourly pay of a 25 year old?
That is, find y when x=25
y = 0.9x - 4.5
= 0.9(25) - 4.5
= 22.5 - 4.5
= 18
y = $18
The prediction for the hourly pay of a 25 year old is $18
Answer:
65/4 or 16.25
Step-by-step explanation:
Because a=8 b=4 c=16, so this equation would be:
c^2/b^2+b^2/a^2
= 16^2 / 4^2 + 4^2 / 8^2
= 256 / 16 + 16 / 64
Times 256/16 by 4 and you would get:
= 1024 / 64 + 16/64
= 1040 / 64
Divide both side by 8, we got:
130/8
Divide both side by 2, we got:
65/4 or 16.25
Hope this helped :3
Answer: (55,9) Explanation is below.
Step-by-step explanation:
What you want to do is try to mutliply one of your equations so that either y or x will be canceled out.
Here is the example:
Say you want to get rid of x, you can multiply the first equation: x-5y=10 by -2 to match the second equation: -2x+6y=-16.
Therefore, the first equation would become -2(x-5y=10)=> -2x+10y=-20
Then subtract the first equation from the second:
(-2x+6y= -16)
- (-2x+10y = -20)
-------------------------
=> 0x-4y= -36
Simplify and then you get y=9.
To find x, plug in y into one of the equations: x-5(9)=10 => x-45=10 => x=55
Sorry if I didn't explain it correctly.
Have a nice day! :D
The line is rising up to the left and it starts at -2,-2
If you were to continue the line to cross the y a is it would cross at (0,-3)
Find the slope
Slope = (-2 - -1) / (—2 - -4) = -1/2
It would be y= -1/2x-3 when x<-2
