The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]
Step-by-step explanation:
In this question we need to find the equation of the graph in factored form.
The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]
where a is y-intercept and r₁, r₂ are x-intercepts
X-intercepts
When y=0, the values of x axis are known as x-intercepts
Y-intercepts
When x=0, the values of y-axis are known as y-intercepts.
Looking at the graph finding x-intercepts
When y=0 x=-2 and 1
So, we have
r₁ = -2
r₂ = 1
Looking at the graph finding y-intercepts
When x=0, y=-4
So, a = -4
Putting values in the formula we will get:
[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]
So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]
i need to know what the answer is we have to combine like terms 10-4+6(4-2)
Answers
Answer:
18
Step-by-step explanation:
Solve the separate part of the equation first
6(4) 6(-2) would equal 24-12
Add it back in to get: 10 - 4 + 24 - 12
-4-12 and 10+24 are the like terms so
10+24 = 34 and -4-12 = -16
Equation in the end: 34-16
Simplify that to: 34-16 = 18
Answer: 18

Two groups of people need to get across a lake. The first group has 36 people. Its boats can carry 5 passengers. The second group has 24 people. Its boats can carry only 4 passengers.
Which group needs more boats?
follow the steps to solve the problem.
1. Group 1 is represented by the equation 5x = 36. Solve this equation for x. Show your work.
2. How many boats does group 1 need? Explain your answer.
3. Write and solve an equation to find how many boats group 2 needs. Show your work.
Answers
Answer:
Both groups need more boats
1.) 5x=36
36/5
=7.2 boats
2.) 7.2 but you can't split a boats nor can you decrease the amount of people so 8 boats.
3.)4x=24
24/4
=6 boats

Answers
What point is on both lines y=12x+3 and y=x+1
(no graph)
Answers
Step-by-step explanation:
by having two equations that have the same point, you can set the two equations equal to each other
y = 12x + 3, y = x + 1
12x + 3 = x + 1
11x = -2
x = -2/11
when you find the the x value, plug it back into either one of the equations
y = x + 1
y = (-2/11) + 1
y = 11/11 - 2/11
y = 9/11
the point (solution):
(-2/11, 9/11)
Answer:
(-2|11, 9|11)
