Which expression is equivalent to 2 (t-4) +1. A 2t-5 B.2t-7 C. 2t-9 D. 2t -3
seraphim [82]

Answer: 2t + -8

Step-by-step explanation: Let's simplify this problem using the distributive property.

The first thing we want to do is change this minus to plus a negative.

Now we can distribute or multiply this 2 times

each of the terms inside the set of parentheses.

So we get 2(t) + 2(-4) and this simplifies to 2t + -8.

2t + -8 is the same thing as 2t -8.

Derivative of this function<br> <br>Y= -7X³ -8X² +6X +3
zaharov [31]

In general, the derivative of a single term  Ax^(n)  is  A n x^(n-1) .

And the derivative of a sum of many terms is the sum of the derivatives
of the individual terms.  

Using these two rules, the derivative (with respect to 'x') of the expression
in the question is . . .

<em>            Y' = -21x² - 16x + 6</em>

Help me out please???
xenn [34]

Answer:

(x,y) => (x+3, y+4)

Step-by-step explanation:

Given a triangle DEF, D(4,2), E(3,3), F(2,1).

Centroid of the area (and the vertices) equals the mean of the coordinates, namely ( (4+3+2)/3, (2+3+1)/3 ) = (3,2)

To translate (3,2) to (6,6), we need the rule

(x,y) => x+(6-3), y+(6-2), or

(x,y) => (x+3, y+4)
