Answer:
4 and 1/4
Step-by-step explanation:
3/4 =6/8 and 6/8 plus 6/8 plus 7/8 plus 7/8 = 26/8 = 4 and 1/4
Answer:
x=8a
Step-by-step explanation:
(3/a) x - 4 = 20
add 4 to both sides
(3/a) x = 24
Divide by 3/a
x = 24 / (3/a)
Use KCF (keep change flip)
x = (24/1) x (a/3)
x = 24a / 3
simplify
x = 8a

Step-by-step explanation:
Question 3: (4, -3)
Solving through elimination: Multiply the first equation by -3.
-3x+6y=-30
3x-5y = 27
Add. The x drops out.
y= -3
Substitute -3 in for y.
x-2y=10
x-2(-3)=10
x+6=10
x=4
Question 4: (2,5)
Solve through elimination: Multiply the second equation with 3.
![\frac{3}{2} x+y=8](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20x%2By%3D8)
![\frac{9}{4} x-y=-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B4%7D%20x-y%3D-%5Cfrac%7B1%7D%7B2%7D)
3/2= 6/4
15/4x=7.5
x=2
3/2 (2) + y = 8
3+ y =8
y=5
Question 5: (6,4)
Use your graph to graph.
![y=-\frac{1}{3} x+6](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B3%7D%20x%2B6)
Slope of -1/3
Y-intercept of 6 (0,6)
X-intercept of 18 (18,0)
![y=\frac{3}{2} x-5](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B2%7D%20x-5)
Slope of 3/2
Y-intercept of -5 (0,-5)
X-intercept of
(
,0)
Question 6: (5, -7)
![Ax+2By=-41](https://tex.z-dn.net/?f=Ax%2B2By%3D-41)
![4Ax-By=88](https://tex.z-dn.net/?f=4Ax-By%3D88)
![3A+2B(4)=-41](https://tex.z-dn.net/?f=3A%2B2B%284%29%3D-41)
![4A(3)-B(4)=88](https://tex.z-dn.net/?f=4A%283%29-B%284%29%3D88)

Step-by-step explanation:
Graph Of The Cubic Function
The cubic function can have one or three real zeros. Each zero corresponds to a point in the x-axis where the value of y is zero. When the coefficient of the cubic term is positive, the function is increasing, then decreasing and finally increasing.
The given function is
f(x)=(x - 3)(x - 1)(x + 1)
There are no options to choose from but I'm including a graph with a plot of f(x) plus the table of values to improve the sketch with more details. The zeros, maximum and minimum values can be clearly seen
