The problem statement says "the graph is shown," but you haven't shared it. Please do that if possible. Thank you.
<span>Heather was asked to graph 2x + 4y = 12 by using slope and y-intercept.
We can quickly put this into slope-intercept form:
12 - 2x
Subtract 2x from both sides: 2x - 2x + 4y = 12 - 2x => y = ------------
4
In simplest form, this is y = 3 - (1/2)x, or (-1/2)x + 3. The slope is -1/2 and the y-intercept is (0,3).</span>
we are given with two points: (-8,8) and (0,1). in this case, we are asked for the equation of the line connecting the two. we first solve for the slope that is (8-1)/(-8-0) equal to 7/-8 or -7/8. We substitute to the point-slope form equation y-y1 = m (x-x1) that is y - 1 = -7/8 * x ; y = -7/8 x + 1
We need to find the value of n in the first equation, so you would do:
- 17 = -3 - 2n
Add 3 to both sides to cancel the -3 in the side of the n variable
- 14 = -2n
Next divide to get rid of the -2 because it is multiplied by the -2
7 = n
54 = 17n - (-3)
Since you know that a negative times a negative transforms into a positive this is what it would look like:
54 = 17n + 3
Subtract 3
51 = 17n
Divide by 17 and n would be
n = 3
Answer:
b = 5
Step-by-step explanation:
The given equation is :
.......(1)
It is in the form of quadratic equation. The general form of a quadratic equation is as follows :
.....(2)
Comparing equations (1) and (2), we get :
a = 0.3, b = 5 and c = -7
Hence, the value of b is equal to 5.
