Answer:
x = -2 or x = 1/2
Step-by-step explanation:
First get the eq in standard form, which means:
x² should not have that 2 in front of it
move the other 2 to the left
so first let's divide by 2:
x² + 3/2 x = 1
now move the 1 to the left
x² + 3/2 x - 1 = 0
now look for two numbers that, when multiplied, give -1, and when added, give 3/2. This is a bit of trial-and-error if you want to solve in this way.
The numbers are 2 and -1/2, since 2*-1/2 = -1, and 2 - 1/2 = 3/2
The factorization thus is:
x² + 3/2 x - 1 = (x+2)(x-1/2) = 0
Either factor (x+2) or (x-1/2) can be zero to solve the solution, hence x = -2 or x = 1/2
Answer:
y = x/2 - 4 slope-intercept form
y = x/2 + 4 slope-intercept form
NO SOLUTION.
The graph is a pair of parallel lines one line through point (0, -4) and the other through point (0, 4)
Step-by-step explanation:
x - 2y = 8 and -2x+4y=-16.
we can easily convert these to slope intercept form
x - 2y = 8
-2y = 8 - x
2y = x - 8
y = x/2 - 8/2
y = x/2 - 4 slope-intercept form
------------------------------
-2x + 4y = 16
4y = 2x + 16
y = 2x/4 + 16/4
y = x/2 + 4 slope-intercept form
We have 2 lines that are parallel because they have the same slope
Volume = v, height = h, area of the base= B
v=h•b
144=h•48
h=144/48
h=3 inches
