Answer:
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]

PROBLEM: Juan hires an electrician. Juan pays a one-time fee of $30. Juan also pays $45 for each hour the electrician works. A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours. Y=mx+b B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job? (Vou should have 9 answers in question 2
Answers
Answer:
A: C=45h+30
B: C=$322.50
Step-by-step explanation:
A: We'll start with the equation for the total charge. Juan is saying he will pay a one time fee of $30, meaning there is 30 dollars added to what ever the hourly wage is. This can be represented by the +30. Now if "h" represents the variable for which the hourly wage will be calculated, and he pays $45 dollars per hour this will be represented as 45h. As an example if I pay you 2 dollars per hour using the same variable "h", this would be represented as 2h. So if you worked for two hours you would get 4 dollars, this is proven by the fact the 2(2) (remeber im replacing the "h" with the hours you worked) obviously 2 times 2 is 4 proving my point. This information will give you the equation you see above.
B: Onto solving for how much Juan will pay. Now you say youre supposed to have 9 answer but this can't be true. All you need to do is plug the hours given into "h" and solve the equation. It should look something like:
C=45h+30
C=45(6.5)+30
Im using a decimal because it should be clear 1/2=0.5
C= 292.5+30
45x6.5 always go with PEMDAS, we are multiplying first. Then add 292.5 plus 30
This results in the answer of:
C=$322.50

Events A and B are independent. The probability of A given B has occurred is 0.43, and the probability of B given A has occurred is 0.35.
What is the probability, to the nearest hundredth, that A and B occur?
Answers
Answer:
0.43* 0.35 = 0.1505 or 0.15 after rounding
Step-by-step explanation:
Based on the probabilities of A and B occurring with conditions, the probability of A and B occurring is 0.15.
What is the probability that both A and B occur?This can be found by the formula:
= Probability that A occurs if B occurs x Probability of B occurring if A occurs
Solving gives:
= 0.43 x 0.35
= 0.15
In conclusion, the probability is 0.15.

What is the solution to -(4x-3) = -7(9+x) ???
Answers
Answer:
The solution is -22
Step-by-step explanation:
The solution of an equation is the value of the variable of the equation
∵ -(4x - 3) = -7(9 + x)
→ Simplify each side
∵ -(4x) - -(3) = -7(9) + -7(x)
∴ (-4x) - (-3) = -63 + (-7x)
→ Remember (-)(-) = (+) and (-)(+) = (-)
∴ -4x + 3 = -63 - 7x
→ Add 7x to both sides
∴ -4x + 7x + 3 = -63 - 7x + 7x
∴ 3x + 3 = -63
→ Subtract 3 from both sides
∵ 3x + 3 - 3 = -63 - 3
∴ 3x = -66
→ Divide both sides by 3
∴ x = -22
∴ The solution is -22

Recall that all angles in a triangle sum up to 180°, therefore:
(9x + 3) + (5x - 2) + (11x - 21) = 180
Combine like terms:
9x + 5x + 11x + 3 - 2 - 21 = 180
25x -20 = 180
Add 20 to both sides:
25x = 200
Divide both sides by 25:
x = 8°
Answer:
Step-by-step explanation:
we know that the sum of the angles in a triangle is 180
(5x-2)+(9x+3)+(11x-21)=180
=5x-2+9x+3+11x-21=180
25x=180+20
25x=200
x=8

David is buying a cheese wheel priced at $ 14 $14dollar sign, 14 before tax. The store charges 8 % 8%8, percent sales tax. What is the total price, including tax, David pays for the cheese wheel? $
Answers
Answer:
$15.12
Step-by-step explanation:
{10 * 0.08 = 0.8
4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)
[0.8 + 0.32 = 1.12]
14 + 1.12 = 15.12
David is buying a cheese wheel priced at $14 on 8% sales tax.
David's pays for the cheese wheel is $15.12 .
Given:
Before-tax, the price of cheese wheel = $ 14
Sales tax on cheese wheel = 8%
Sales tax is 8% of $14
[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]
So, the sales tax on the cheese wheel is $1.12
The total price of the cheese wheel, including tax = $ 14 + $1.12 = $15.12
Therefore, David's pays for the cheese wheel is $15.12 .

Slove the system of equations by useing the substitution method. 2x - 3y=9 y=x-4
Answers
Answer:
x = 3
y = -1
Step-by-step explanation:
in this system, we are given that y = x - 4
this means that we can take the other equation and replace y with x - 4:
so 2x - 3y=9 turns into
2x -3 (x - 4) = 9
distribute -3 to x and -4:
2x - 3x + 12 = 9
add like terms and subtract 12 from both sides
-x = -3
divide both sides by -1 to get rid of the negative on x:
x = 3
now we have the value of x, so we can replace the x in y = x - 4 with the value we just got
so y = x- 4 turns into
y = (3) - 4
solve and you get
y = -1
