find the value of a if the line joining the points (3a,4) and (a,-3) has a gradient of 1
Answers
Recall that the slope or gradient of a line segment through two points is the ratio of the change in the y coordinate to the change in the x coordinate.
If the gradient is 1, then
1 = (-3 - 4) / (a - 3a)
Solve for a :
1 = -7 / (-2a)
1 = 7/(2a)
2a = 7
a = 7/2

From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985
Answers
The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]
Given that:
[tex]R(t) = t^2 + 7t + 159[/tex]
[tex]c(t) = t^2 + 131[/tex]
The profit function P(t) is calculated as follows:
[tex]P(t) = R(t) - c(t)[/tex]
So, we have:
[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]
Open brackets
[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]
Collect like terms
[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]
[tex]P(t) = 7t + 28[/tex]
Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Jane is solving the equasion -2x + 4 = 18. She tells her partner that they should add two to both sides first since that is the inverse of -2. Did Jane start this equation correctly? Explain your reasoning
Answers
Answer:
No
Step-by-step explanation:
Given
- 2x + 4 = 18
note the inverse of - 2 is - [tex]\frac{1}{2}[/tex] not - 2
However , the first step is to isolate the term in x by subtracting 4 from both sides.
- 2x = 18 - 4 = 14 ( divide both sides by - 2 )
x = - 7

Answers
Answer:
26
Step-by-step explanation:
It says find f(f(2)), so we need to find f(2) and then input that into the same function. f(2)=5 so then we input that into the function again and get 26. Boom.
Answer:
26
Step-by-step explanation:
Ok first u find f(2) so for that u have to input 2 into the value of x. So 2^2 +1 =5
When we get 5 we input THAT into f(x)
So:
F(5) = 5^2 +1
=26

6.7x10 =
Answers
Answer: 67
Step-by-step explanation:
When you multiply with numbers like 10, 100, 1000, 10000, and so on you just have too right or left (division : left)(multiplication : right) according to the zero's. Like 100 has 2 zero's so then if you're multiplying with that you will go 2 to the right, and dividing you will go 2 to the left. Lets apply the same logic here, the question is 6.7 x 10, 10 has 1 zero and we are multiplying here so then, we have to go to the right, so 6.7 will become 67.
