Answer:
a. x^2 - 1
b. x^2 - 6x + 9
c. [tex]\dfrac{3x + 1}{x^2 + x}[/tex]
Step-by-step explanation:
a.
(x + 1)(x - 1) =
= x^2 - x + x - 1
= x^2 - 1
b.
(x - 3)^2 =
= (x - 3)(x - 3)
= x^2 - 3x - 3x + 9
= x^2 - 6x + 9
c.
[tex] \dfrac{3 + \frac{1}{x}}{1 + x} = [/tex]
[tex] = \dfrac{x(3 + \frac{1}{x})}{x(1 + x)} [/tex]
[tex] = \dfrac{3x + 1}{x + x^2} [/tex]
[tex] = \dfrac{3x + 1}{x^2 + x} [/tex]

The graph shows the absolute value parent function.
Which statement best describes the function?
example of absolute value
F( x )=| x |
Step-by-step explanation:
In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign. Namely, |x| = x if x is positive, and |x| = −x if x is negative (in which case −x is positive), and |0| = 0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.
Share 96 sheep in the ratio 7:1:4
Answer:
56:8:48
Step-by-step explanation:
1] add th eratio numbers together
7+1+4=12
2} write the ratio as fractions
7/12 1/12 4/12
3] use the formula (ration number/total number * number of sheeps)
a] 7/12 * 96 = 56
b] 1/12 * 96 = 8
c] 4/12 * 96 = 48
3] write your answer as a ration
7 : 1 : 4 = 56 : 8 : 48
Answer:
The answer is 56 : 8 : 32
Step-by-step explanation:
7 + 1 + 4 = 12
7/12 x 96 = 56
1/2 x 96 = 8
4/12 x 96 = 32
Who’s is a graph Line with a negative slope and positive y-intercept
Answer:
The second one
Step-by-step explanation:
A sequence is shown below.
32, 26, 20, 14...
Which explicit formula can be used to determine the nth term in the sequence?
a^n =6n+38
a^n= -6n+38
a^n= -6n+32
a^n= 6n+32
Answer:
a^n = -6n + 32
Step-by-step explanation:
32 - 6 = 26
26 - 6 = 32 - 6.2 = 20
20 - 6 = 32 - 6.3 = 14
-> a^n = -6n + 32

Please classify the following equations as parallel, perpendicular, intersecting, or coinciding (same line):
y = 3x + 2
9x - 3y = -6
Answer:
Intersecting
Step-by-step explanation:
Parallel lines means it will have the same slope, and perpendicular means the slope will be it's reciprocal, so the slope would be 1/3 x instead of 9x. Conciding means it's the exact same equation, so the answer has to be intersecting.

What is the slope of a line parallel to the line whose equation is: -2x + y = - 7?
Answer:
2
Step-by-step explanation:
-2x+y=-7
Take the -2x and put it on the other side of the equation by changing the sign
y=-7+2x
Now put it in y intecpet form by putting the 2x first
y=2x-7
Slope is the number before the x.
so 2
Now knowing that parallel lines always have the same slope the answer is 2
PLEASE HELPWhich line has an equation of Y-5X+4 in slope-intercept form?
a line passing through the points (1, 9) and (3, 19)
a line passing through the points (2, -14) and (4,-24)
a line passing through the points (1, 1) and (3, 11)
a line passing through the points (2. -6) and (4, -16)
Answer:
a line passing through the points (2, -6) and (4, -16)
Step-by-step explanation:
y=-5x+4
you plug in the x value and put the y value on the left side of the equation
for example
-6 = -5(2) + 4
then solve to see if it works
-5(2) = -10 + 4 = -6
(2, -6) works
-16 = -5(4) +4
-5(4) = -20
-20 + 4 = -16
(4, -16) works
