Answer:
96 ft/s toward home plate
Step-by-step explanation:
because I Know this because I actually teached a class about this
Use desmos.com/calculator and use the graph to figure out which one represents the function. Just type each one in individually and you will find your answer.
Answer:
x² + 1 = 0
Step-by-step explanation:
You can form any with discriminant negative (B²-4AC < 0)
An example could be:
x² + 1 = 0
x² = -1 which has no real roots/solutions
Answer:
2x + 5y = -15
Step-by-step explanation:
First, find the <em>Rate of change</em> [<em>Slope</em>]:
-y₁ + y₂\-x₁ + x₂ = m
1 - 7\5 + 10 = -⅖
Apply the Point-Slope Formula, <em>y - y₁ = m(x - x₁)</em>, since we are given points. It does not matter which one you choose. NOTE: All negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the coordinates into the formula with their CORRECT signs:
y + 7 = -⅖(x - 10)
y + 7 = -⅖x + 4
- 7 - 7
_________________
y = -⅖x - 3 >> Line in <em>Slope-Intercept Form</em>
Here it is in <em>Standard Form</em>:
y = -⅖x - 3
+⅖x +⅖x
____________
⅖x + y = -3 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅖x + y = -3]
2x + 5y = -15 >> Line in <em>Standard Form</em>
__________________________________________________________
y + 1 = -⅖(x + 5)
y + 1 = -⅖x - 2
- 1 - 1
________________
y = -⅖x - 3 Line in <em>Slope-Intercept</em><em> </em><em>Form</em><em> </em>
y = -⅖x - 3
+⅖x +⅖x
___________
⅖x + y = -3 [We do not want fractions in our Standard Equations, so multiply by the denominator to get rid of it.]
5[⅖x + y = -3]
2x + 5y = -15 >> Line in <em>Standard Form</em>
** You see? I told you it did not matter which ordered pair you choose because you will always get the EXACT SAME RESULT.
