Which expression is equivalent to -3(4x-0.50)? PLEASEEEEEEEEEEEEE HELPPP

Misha Larkins [42]

Final Answer: $-12x + 1.5$

Steps/Reasons/Explanation:

Question: Which expression is equivalent to $-3(4x - 0.50)?$

Step 1: Expand by distributing terms.

$-3$ × $4x - 3$ × $-0.50$

Step 2: Simplify $-3$ × $4x$ to $-12x$ .

$-12x - 3$ × $-0.50$

Step 3: Simplify $3$ × $-0.50$ to $-1.5$ .

$-12x - (-1.5)$

Step 4: Remove parentheses and add.

$-12x + 1.5$

classify each angle pair using all the names that apply using the diagram on the left , answering 1 2 3 4 and 5 , explain why.(

vredina [299]

Answer:

see the attachment

Step-by-step explanation:

1. Two angles that sum to 90° are complementary, whether they are adjacent or not. Angles LMN and NMP are also adjacent.

2. Vertical angles created by two distinct lines are never adjacent. The sides of the angles are created by the same lines, and the angles share a vertex, but there is no ray that is a side common to both angles.

3. Angle GMK is supplementary to angle JMG.

4. Vertical angles are congruent. See question 2.

5. See question 1.

Find the midpoint between the points (7, -2) and (-4, 2). Write your answer in the proper form using parentheses

Elan Coil [88]

Answer:

( 1.5, 0)

Step-by-step explanation:

1. Find the coordinates ; in this case (7,-2) and (-4, 2)

2. Plug it into the formula (x1 + x2 ÷ 2 ) , (y1 + y2 ÷ 2)

3. ( 7 + -4 ÷2) = 1.5 And ( -2 + 2 ÷ 2) = 0

4. Therefore, the midpoint is ( 1.5, 0 )

x^2+1/2x+1/16=4/9 Factor the perfect-square trinomial on the left side of the equation. (x + )² = 4/9

Nezavi [6.7K]

The missing number is the square-root of the constant term on the left-hand-side, which equals sqrt(1/16)=1/sqrt(16)=1/4.
Check:
(x+1/4)^2=x^2+2*(1/4)x+(1/4)^2=x^2+x/2+1/16. ok

Answer: x= 1/4

Solve the simultaneous equations x + 6y = 20 x + 3y = 14 x = Y=

xxTIMURxx [149]

Answer:

x = 8, y = 2

Step-by-step explanation:

Multiply the second equation by -2:

x + 6y = 20

-2x - 6y = -28

Add the equations and simplify:

-x = -8

x = 8

Plug x = 8 back into the first equation and solve for y:

8 + 6y = 20

6y = 12

y = 2
