We have the following expression:
 4x + 1 = 6x - 2
 We clear x of the expression.
 We pass the variables to the right and the constant terms to the left:
 1 + 2 = 6x-4x
 We rewrite the expression:
 3 = 2x
 We passed the 2 to divide:
 3/2 = x
 Answer:
 
The value of x is:
 
x = 3/2

If a turtle walks 7/8 of a mile in 50 mins how far will he govin 60 mins​
max2010maxim [7]

50 min = 7/8 miles

1 min

= 7/8 ÷ 50 miles

= 7/8 × 1/50 miles

= 7/400 miles

So, 60 min

= 7/400 × 60 miles

= 7/40 × 6 miles

= 7/20 × 3 miles

= 21/20 miles

= 1.05 miles

Hola que es <br> 34+34+34+34+3+43+4+34+3+4+3
natka813 [3]

Answer: 230. 34 times five is 170. Then you are left with 170 + 3 + 43 + 4 + 3 +4 + 3. You can combine the 3's and you get 9. You are left with 179 + 4 +4 + 43 You combine the 4's and you get 187. 187 + 43 = 230.

If f(x) is a third degree polynomial function and g(x) = f(–2x), which of the following is NOT true?
valina [46]

Answer:

f(x) and g(x) have the same x-intercepts (is <em>not true</em>)

Step-by-step explanation:

g(x) is a reflection across the y-axis and a horizontal compression of f(x). In general those transformations will move the x-intercepts. (The y-intercept and the number of x-intercepts will remain unchanged.)

_____

<em>Comment on the question/answer</em>

f(x) = x^3 is a 3rd degree polynomial. When transformed to g(x) = -8x^2, its only x-intercept (x=0) remains the same. The answer above will not apply in any instance where the only x-intercept is on the line of reflection. (The question is flawed in that it does not make any exception for such functions.)
