Answer:
For Question 3, all you have to do is subtract 5 from both sides of the equation, then divide by -3, which will leave you with 5 as the answer.
-3x + 5 = -10
-3x = -15x
x = 5
-5 -5
Subtract-5 from both sides because the opposite +5 is -5 so they cancel out.
-3x=-15
3. 3
Divide -3 from both sides so they can cancel each other out. So -15 divided by -3 would equal 5 because a negative and a negative makes a positive.
Which equals:
x=5
And to check your work you can just plug in 5 into x because 5 is X.
-3(5)+5=-10
Negative 3 times 5 equals -15 and plus 5 equals -10.
-10=-10
Which mean it is right cause they are the same number (-10) but if it were to be a different number it would be wrong. That’s how you can check your work. Just plug in X into the (x) equation. hope it help!! :))

Step-by-step explanation:
1. Use this [tex]\frac{f(b)-f(a)}{b-a}[/tex] to find the average rate of change
2. Average rate of change = [tex]\frac{f(8)-f(6)}{8-6}[/tex]
3. [tex]f(8) = - 4[/tex] and [tex]f(6) = -10[/tex] (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))
4. Replace -4 to f(8) and -10 to f(6)
5. So it will look like[tex]\frac{-4-(-10)}{8-6}[/tex]

[tex]y+3=\frac{2}{5} (x+5)[/tex]
Step-by-step explanation:
First, let's find the slope using the 2 given points and the slope equation.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Enter in the points:
[tex]m=\frac{-3--1}{-5-0}[/tex]
Simplify:
[tex]m=\frac{-2}{-5}[/tex]
[tex]m=\frac{2}{5}[/tex]
Now that we have slope we can just use one of the points given. Remember point-slope form:
[tex]y-y1=m(x-x1)[/tex]
I'll use the point (-5,-3) in this case.
So, your solution is
[tex]y+3=\frac{2}{5} (x+5)[/tex]
Hope this helps!

All of the ingredients are purchased in bulk sizes. The butter comes in 12-cup containers. How many recipes will each container of butter be able to make?
Answers
Answer:
some information is missing, so I looked for similar questions and found the attached image:
since each recipe requires ¹/₂ cup of butter, you are able to make 12 ÷ ¹/₂ = 24 recipes with one container of butter (assuming you have all the other ingredients).
One-half, ¹/₂, is a fraction that can also be written in decimal form as 0.5. Two times ¹/₂ is equal to 1, and similarly, twenty four times ¹/₂ is equal to 12.
Starting from the same place a plane took 1 hr longer to fly 705 mi to Atlanta, than to fly 470 mi to New Orleans. If the plane flew at the same rate for the entire trip, what was the flying time for the shorter leg? a. 1 2 hr c. 1 1 2 hrs b. 1hr d. 2 hrs
Answers
Answer: d. 2 hrs
Step-by-step explanation:
Let x = Time taken(in hours) to fly 470 mi to New Orleans. (Shorter leg)
Then Time taken to fly 705 mi to Atlanta= x+1 (longer leg)
Since the plane flew at the same rate for the entire trip.
i.e. Speed 705 mi to Atlanta = Speed to fly to New orleans
[tex]\Rightarrow\ \dfrac{705}{x+1}=\dfrac{470}{x}\ \ \ \ \ \ \ [\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}]\\\\\Rightarrow\ 705x=470(x+1)\\\\\Rightarrow\ 705x=470x+470\\\\\Rightarrow\ 705x-470x=470 \\\\\Rightarrow\ 235x=470\\\\\Rightarrow\ x=\dfrac{470}{235} \\\\\Rightarrow\ x=2[/tex]
hence, the flying time for the shorter leg = 2 hours

Willy Wonka has x chocolate bars in his factory. He gives one third of the chocolate bars to Charlie, and eats one half of the remaining chocolate bars. If he is left with 90 chocolate bars in the factory, what is the value of x?
Answers
Answer: The value of x= 270
Step-by-step explanation:
Given: Willy Wonka has x chocolate bars in his factory.
Chocolates he gave = [tex]\dfrac13 x[/tex]
Remaining chocolates = [tex]x-\dfrac{x}{3}=\dfrac{2x}{3}[/tex]
Half of the remaining chocolate bars = [tex]\dfrac12\times\dfrac{2x}{3}=\dfrac{x}{3}[/tex]
Now , Chocolate left [tex]x-\dfrac{x}{3}-\dfrac{x}{3}=\dfrac{3x-2x}{3}=\dfrac{x}{3}[/tex]
As per given , [tex]\dfrac x3=90[/tex]
[tex]\Rightarrow\ x=90\times3=270[/tex]
Hence, the value of x= 270

Step-by-step explanation:
Given that f(x)=4x3-12x2+10 and g(x)=x3 – 2x2 + 5x
The value of f(x)- g(x)= ax'+bx?+ cx+d. What are the values of the coefficients a,b,c,d?
Answers
Answer:
The values of a,b,c and d are as follows:
a = 3, b = -12, c = -5, d = 10
Step-by-step explanation:
Given functions are:
[tex]f(x) = 4x^3-12x^2+10\\g(x) = x^3-2x^2+5x[/tex]
We have to find the value of f(x) - g(x). This means we have to subtract function g(x) from function f(x)
So,
[tex]f(x) - g(x) = (4x^3-12x^2+10)-(x^3-2x^2+5x)\\= 4x^3-12x^2+10-x^3+2x^2-5x[/tex]
Combining alike terms
[tex]= 4x^3-x^3-12x^2+2x^2-5x+10\\= 3x^3-10x^2-5x+10[/tex]
Now it was given that:
f(x)- g(x)= ax^3+bx^2+ cx+d
By comparing both we get
a = 3, b = -12, c = -5, d = 10
Hence,
The values of a,b,c and d are as follows:
a = 3, b = -12, c = -5, d = 10
