Answer:
3.37= true 3.38=false
Step-by-step explanation:
3.37. fill in the blanks
then multiply them together
and you get your answer
3.38. fill in the blanks
then find the exponent of 2
then times that by 3
And you get your answer
3.40. write down your order of operations PEMDAS
so first you do the parentheses (7+3)=10
then you see if there is any exponents
there is so you do that next (10^2)=100
then you see if there is any multiplication
there is so you do 2×100= 200
there now you got you answer
Y=x^2+13x
complete the square to get it into form y=a(x-h)^2+k whre (h,k) is the vertex
y=x^2+13x
y=(x^2+13x)
13/2=6.5, 6.5^2=42.25
y=(x^2+13x+42.25-42.25)
y=((x+6.5)^2-42.25)
y=(x-(-6.5))^2+(-42.25)
the vertex is (-6.5,-42.25)
Answer:0.2419218956
Step-by-step explanation:
Answer:
x= 2,
,y = 5
Step-by-step explanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 5
// Plug this in for variable y in equation [2]
[2] -4x + 2•(5x-5) = 2
[2] 6x = 12
// Solve equation [2] for the variable x
[2] 6x = 12
[2] x = 2
// By now we know this much :
x = 2
y = 5x-5
// Use the x value to solve for y
y = 5(2)-5 = 5
Solution :
{x,y} = {2,5}
In this equation, p=27 because it is the last term and q=3 because it is the coefficient of the first term. First find all divisors of these numbers:
27: 1, 3, 9, 27
3:1, 3
Then use +/- p/q to find all possible combinations
+/-1, +/-3, +/-9, +/-27, +/- 1/3
Or your answer can be written as: 1, -1, 3, -3, 9, -9, 27,-27, 1/3, -1/3
Hope this helps!
