Write an equivalent expression using distributive property and simplify for each question

Lana71 [14]

Answer:

Check explanations

Step-by-step explanation:

For all real numbers a,b, and c, the distributive property states that:

$a(b + c) = ab + ac$

For Part A, we have

$2x + 10x = x(2 + 10) = x(12) = 12x$

$2x + 10x = 2x(1 + 5) = 2x(6) = 12x$

For Part B, we have

-4(3x-10)+5(2-6x)=-4*3x--4*10+5*2-5*6x

This simplifies to:

-4(3x-10)+5(2-6x)=-12x+40+10-30x

-4(3x-10)+5(2-6x)=-12x-30x+40+10

-4(3x-10)+5(2-6x)=-42x+50

For the C part, we have:

$2(x - 4) + x = 2 \times x - 2 \times 4 + x$

$2(x - 4) + x = 2x - 8+ x$

$2(x - 4) + x = 3x - 8$

For Part D, we have:

$-3-7(3-4x)+8x = - 3 - 7 \times 3 - 7 \times - 4x + 8x$

We simplify to get:

$-3-7(3-4x)+8x = - 24+28x + 8x$

Simplify further to get:

$-3-7(3-4x)+8x =-24+36x$

The variables x and y vary inversely. When y is 10, x is 10. What is x when y is 20

dezoksy [38]

inversely
y = k/x
k = yx
k = 10*10 = 100

when y = 20

20 = 100/x
20x = 100
x = 5

answer
 x = 5 when y is 20

A segment in the coordinate plane has an endpoint with coordinates (1,2) and midpoint with coordinates (4,3). What are the coord

Serga [27]

Answer:

(7,4)

Step-by-step explanation:

midpoint formula (x1+x2)/2 , (y1+y2)/2

Look at x and y for the endpoints separately

midpoint x value = ( 1 + x)/2

4= (1 + x)/2

8 = 1 + x

x = 7

midpoint y value = (2 + y)/2

3 = (2 + y)/2

6 = 2 + y

y = 4

endpoint (x,y) = (7,4)
