f(x) = 3x + 2

g(x) = - 2x + 1

f(x) - g(x) = 3x + 2 - ( - 2x + 1 ) = 3x + 2 + 2x - 1 = 5x + 1

Write an equation of a line that passes through the point (8,4) and is parallel to the y=4x+2

fomenos

Answer: $y=4x-28$

Step-by-step explanation:

The Slope-intercept form of the equation of the line is:

$y=mx+b$

m: is the slope.

b: the intersection of the line with the y-axis.

The equation of the line $y=4x+2$ has:

$m=4\\b=2$

If both lines are parallel, then their slopes are equal. So the slope of the other line is:

$m=4$

To find "b", substitute the given point and the slope into $]y=mx+b$ and solve for "b":

$4=4(8)+b\\4-32=b\\b=-28$

Then the equation of this line is:

$y=4x-28$

If the combined area of the white and orange regions is 100π, what is the area of ONLY the orange region?

7nadin3 [17]

64π is correct, since the area of the white circle is 36π, and 100π - 36π = 64π.

Is -0.75 bigger or less than -0.4?

masya89 [10]

Answer:

Because they are both negative that means they are on the left side so -0.4 is closer to the 0 so less.
