You can change it to Slope-Intercept form. That’s what I do as it’s easier to tell what is the slope and the y-intercept.
y=mx+b
2x + 3y = 6
3y = -2x + 6
y = -2/3x + 2
Steps:
Isolate y (move 2x to the other side) and change the sign of 2x (positive to negative). Divide everything in the equation by 3 in order to get y by itself.
Now that you have the equation, the slope is -2/3 and the y-intercept is 2. What I would do it start at 2 on the y axis and go down 2 units and to the right 3 units. The other way would be start at 2 on the y axis and go up 2 units on the y axis and then to the left 3 units. Your line should be a straight, diagonal line going down (in \ <— direction).
Hope this helped!! Tried to be as informative as possible.
Answer:65.6
Step-by-step explanation:
So $0.25 per yard
16.4/$0.25=65.6
Answer: -231 ft
<u>Step-by-step explanation:</u>
The submarine started at sea level = 0
It submerged 140 ft = -140 ft
It traveled 40 miles horizontally so it is still at -140 ft
It dove down an additional 120 ft = -260 ft <em>(-140 + -120)</em>
It traveled 25 miles horizontally so it is still at -260 ft
It rose 29 ft = -231 ft <em>(-260 + 29)</em>
Note: submerged and dove are negative values and rose is positive
0 - 140 - 120 + 29 = -231
Answer:
x = –7, x = 2, or x = 4 are factors of f(x).
Step-by-step explanation:
Given : f(x) = 5x³ +5x²-170x +280 and x + 7 is one factor .
To find : What are all the roots of the function.
Solution : f(x) = 5x³ +5x²-170x +280 .
We have given that x + 7 is factor that mean x = -7 is factor of f(x )
When we divide f(x) by x +7 we get
5x² -30x +40 =0
Taking common 5 from equation
5( x² -6x +8) =0
On dividing by 5 both sides
x² -6x +8 = 0
On factoring
x² -2x -4x +8 = 0.
Taking common x from first two terms and -4 from last two terms
x ( x -2) -4 (x -2) = 0
On grouping
(x-2) (x-4) = 0
x -2 =0
x =2
x-4 =0
x = 4
Therefore, x = –7, x = 2, or x = 4 are factors of f(x).
