Answer:
5 5/8 inches
Step-by-step explanation:
Set up and solve an equation of ratios:
x 1
------- = -------
30 ft 64
Then 64x = 30 ft, and x (the length of the model car) is 30/64 ft, or
x = 0.469 ft, or 5 5/8 inches
Answer:
~Re-write the equation~
SOLVE:
5x(3)+4x (2-9)+(2x+1)+(2x2+x-3)
5(1)(3)=15
4(2-9)=8+36=44
2x+1=3
2x2+x-3:4(1)-3=1
15+44+3+1
ANSWER=63x
Step-by-step explanation:
I wasn't quite sure because of the way you wrote it but here's an answer!
Answer:
A. (The first one)
Step-by-step explanation:
The line is reasonable if it follows a closely similar or identical path to the dots on a graph. In this particular graph, the line seems to be a close fit, since it goes through a majority of the points and follows a simliar path.
Thus, the answer is A. (The first option choice)
I hope this helps!
Hello there. To solve this question, we'll simply have to make x => x + 5 in the function.
Given the function:
We have to determine f(x + 5)
By making x => x + 5 in this function, we get:
Now remember the binomial expansion of order 2:
Therefore we have:
Multiply the terms inside parentheses and calculate the square.
Apply the distributive property
Multiply and add the numbers
This is the answer we're looking for.
A way of showing this is the correct answer is to make x = 1 and x = 6 in the former function:
Then making x = 1 in the expression we found after:
As expected.
