Answer:
1. C 2.D 3.D 4.A
Step-by-step explanation:
The first one would be C because the slope is -1, which can also be -x and the y-intercept is 0, meaning you don't need to add or subtract anything.
The second one is D because the slope is -3, meaning it's -3x, and the y-intercept is positive, meaning you add 5.
The third one is D because the slope is 5/4, which is 5/4x and the y-intercept is positive 3, meaning you add 3.
And the fourth one is A because there is no slope, so y would just equal 3.
Answer:
7x+6 = 5(x+6)
Step-by-step explanation:
x represents Harry's age now, so 7x represents Nick's age now. (Nick is 7 times as old as Harry.)
In 6 years, Harry's age will be x+6.
In 6 years, Nick's age will be 7x+6, which is 5 times Harry's age at that time, 5(x+6). Hence an appropriate equation is ...
... 7x+6 = 5(x+6)
_____
Please note that finding the value of x does not give the answer to the question. We are asked for Harry's age in 6 years, so the answer is x+6 (=18).
Answer: 21
steps:
1) 6(4) - 3
2) 24 - 3
3) 21
-5x^5 * -8x^4 - 5x^5*-9x - 5x^5*-9
= 40x^9 + 45x^6 + 45x^5
Answer with explanation:
The given mathematical expression to solve : 
The prime factorization of each term can be written as follows :-


We can see that the greatest common factor of both the terms = 
So we rewrite the given expression as :-

By using distributive property :-
, we have
