Answer:
y=
x-2
Step-by-step explanation:
Slope intercept form is a way to describe a function using its slope and y-intercept and is written as y=mx+b.
m=slope
b=y-intercept
Looking at the graph we can see it goes through x=0 at y=-2 making -2 the y-intercept.
Then we must solve for slope, slope is rise/run. From the point (0,-2) the function travels to (7,0).
This gives us a rise (change in x) of 2 and a run (change in y) of 7 and 2/7 as our slope.
Step by step explanation: I'm Sorry this answer is late but here! I don't really get number 2 I'm sorry.
question 1
x=-y
2x-y=-6
x=-y
2(-y)-y=-6
x=-y
y=2
x=-(2
y=2
(-2,2)
x=-2,
y=2
Question 2
-2x + 6y = 30
-2x + 6y + -6y = 30 + -6y
-2x + 0 = 30 + -6y
-2x = 30 + -6y
x = -15 + 3y
x = -15 + 3y
Answer: 2.8%
Step-by-step explanation:
On the first roll, probability to get a 3 is 1/6.
On the second roll probability to get a 4 is also 1/6.
To get both of these numbers together, you need to multiply the two probabilities.
1/6 x 1/6 = 1/36.
1/36 = ~2.8
2.8%
Answer:
The vertex is (3,4)
Step-by-step explanation:
f (x) = x^2 - 6 x + 13
Completing the square
-6/2 = -3 and squaring it = 9
= x^2 -6x +9 +4
= ( x-3) ^2 +4
The equation is now in vertex form
a( x-h) ^2 +k
where the vertex is ( h,k)
The vertex is (3,4)
