Answer:
20x-13/10
Step-by-step explanation:
change made to your input should not affect the solution
1) 1.7 replaced by (17/10).
2) simplify 17/10
then it equals to 3/10x - 13/10 + 17/10x
3) simplify 13/10
4) simplify 3/10
5) combine the numerator together put the sum or difference over the common denominator then reduce to lowest terms if possible
3x-13/10
6) add it back to 17x/10
3x-13/10 + 17x/10
you will get my answer mentioned above
hope this is helpful to you

One of the roots of the equation x2−bx+c=0 is equal to 5. Find c in terms of b.
Answer:
c=5b-25
Step-by-step explanation:
Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
The value of c in terms of b is 5b - 25
What is a polynomial?Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
Example:
x² + 3x + 9 is an equation.
x³ + 6x² + 6x + 8 is an equation.
We have,
x² - bx + c = 0
One of the roots of this equation is 5.
This means,
5² - 5b + c = 0
25 - 5b + c = 0
Adding 5b on both sides.
25 + c = 5b
Subtracting 25 on both sides.
c = 5b - 25
Thus,
The value of c in terms of b is 5b - 25

Rewrite the absolute value function y=|x|-3 as two linear functions, one that has the domain x<0, and one that has the domain x≥0.
Two linear functions, one that has the domain x < 0 is y = - x - 3
And, one that has the domain x ≥ 0 is y = x + 3.
What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
We have to given that;
The absolute value function is,
⇒ y = |x| - 3
So, The linear function which has the domain x < 0 is,
⇒ y = - x - 3
And, The linear function which has the domain x ≥ 0 is,
⇒ y = x - 3

Answer:
I am pretty sure it's the first one with the table
Step-by-step explanation:
All of the numbers from the x side can be times by 4 to get the y value and that goes for all of the x values which means that it is proportional
Answer:
I think its either the first one

Darius created a factor tree and wrote the prime factorization of 60 shown here.
A factor tree of 60. 60 branches to 4 and 15. 4 branches to 2 and 2. 15 branches to 3 and 5.
60 = 2 × 3 × 5
What is Darius’s error?
Answer: he needs to finish factoring the 4s.
Step-by-step explanation:
4x15 is 60, so that is right, 3x5 is 15, so that’s is right, 2x2 is 4, so that is right, but he didn’t finish factoring. 1x1 is 2, so he should have 1 and 1 coming from each 2 on the tree. Hope this helps.
