There's no equation to solve, until you tell us
what that expression is equal to.
Answer:
5
Step-by-step explanation:
1) Solve for the slope(m):
(y2-y1) / (x2-x1)
pick any
(-3 - (-5) )/ (1 - 0)
(-3 + 5) / (1 - 0)
2/1 = 2
2) b(intercept) value is found when x = 0:
x = 0, y = -5,
b = y
b = -5
3) Plug it in:
y = mx + b
y = 2x - 5
4) when the value is 5, x = 5:
y = 2x - 5
y = 2(5) - 5
y = 10 -5 = 5
so, this is a quadratic equation, meaning two solutions, and we have a factored form of it, meaning you can get the solutions by simply zeroing out the f(x).
so the zeros/solutions are at x = 3 and x = -11, now, bearing in mind the vertex will be half-way between those two, checking the number line, that midpoint will be at x = -4, so the vertex is right there, well, what's f(x) when x = -4?
Answer:
Option C is correct.
Equation of a line passing through (0,6) and (9,0).
Explanation:
Given the two points (0, 6) and (9 ,0).
To find the equation for the given two points and is,
; where m is the slope and is given by:
First find the slope m:
Substitute this value in equation of line:
or
⇒
Therefore, the equation for the given point is:
We need the perimeter of the window for framing
The window is in the shape of a rectangle with the height of
feet and width of
. The diagram of the shape is shown below
The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.
The perimeter of the window is
=
We have two whole numbers 18 and 12 and two fractions
and
Adding the two fractions that have different denominator
, which is an improper fraction which we can change into a mixed number
So the perimeter of the window is
and the length of wood needed for the frame is
feet
