Answer:
ali probley has a 50% chance
Step-by-step explanation:
The answer is to your question is B)4. Its y=mx+b and m is your slope and 4 is thw m.
Use completing the square:
Ex:
Now apply to your problem.
First factor out the '4' in front of the 'x^2' term
Apply completing the square:
![y = 4(x^2 + \frac{7}{4}x +(\frac{7/4}{2})^2 -(\frac{7/4}{2})^2) \\ \\ y = 4[(x^2 + \frac{7}{4}x+\frac{49}{64}) - \frac{49}{64} ] \\ \\ y = 4(x + \frac{7}{8})^2 - \frac{49}{16}](https://tex.z-dn.net/?f=y%20%3D%204%28x%5E2%20%2B%20%5Cfrac%7B7%7D%7B4%7Dx%20%2B%28%5Cfrac%7B7%2F4%7D%7B2%7D%29%5E2%20-%28%5Cfrac%7B7%2F4%7D%7B2%7D%29%5E2%29%20%5C%5C%20%20%5C%5C%20y%20%3D%204%5B%28x%5E2%20%2B%20%5Cfrac%7B7%7D%7B4%7Dx%2B%5Cfrac%7B49%7D%7B64%7D%29%20-%20%5Cfrac%7B49%7D%7B64%7D%20%5D%20%5C%5C%20%20%5C%5C%20y%20%3D%204%28x%20%2B%20%5Cfrac%7B7%7D%7B8%7D%29%5E2%20-%20%5Cfrac%7B49%7D%7B16%7D)
It is 5 becuase 5 times 1 is 5
<u><em>Answer: Addition property of equality, Subtraction property of equality, Multiplication property of equality, and Division property of equality.</em></u>
Step-by-step explanation:
Addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
Example: t-6=13
add 6 both sides of an equation.
t-6+6=13+6
answer: t=19
________________________________________________________
Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
11=x+5
switch sides of equation
x+5=11
subtract by 5 both sides of an equation.
x+5-5=11=5
answer: x=6
___________________________________________________________
Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
a*c=b*c
t/5=3
example:
5/1*t/5=3*5
then multiply on the right side.
t=3*5
answer: t=15
______________________________________________________
Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a/c=b/c for c≠0
10a/10=130/10
divide by 10 both sides of an equation.
10a/10=130/10
simplify.
130/10=13
answer: a=13
