Answer choice A is incorrect as it is missing the variable 'x' in it.
Let's test answer choice B.
y = mx + b
m is the slope
b is the y-intercept
m = 2/3
b = -5
y = (2/3)x - 5
B is one of the answers.
Let's test answer choice C.
6y = 4x -30
y = (4/6)x - 30/6
y = (2/3)x - 5
Answer choice C is also correct.
Let's test answer choice D now.
y = (2/3)x - 5
Plug in (3,-3)
-3 = (2/3)(3) - 5
-3 = 2 - 5
-3 = -3
This is correct, so therefore D is also one of the answers.
Your answer is B, C and D.
Answer:
x=5, y=41
Step-by-step explanation:
Because both equations are equal to Y, you can set them equal to each other like this:
8x+1=3x+26
From here, solve for x:
1. 5x+1=26
2. 5x=25
3. x=5
Once you have x, plug it back in to one of the original equations:
y=8(5)+1
y=41 and then you have your answer

Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.
