Solve for x: -2|4x + 12| = -32 (5 points)
no solution
x = 1, x = -1
x = 1x = -7
x = -1, x = 7
Answer:
x = 1, x = -7
Step-by-step explanation:
Step 1: Divide both sides by -2.
[tex]\frac{-2(|4x+12|)}{-2} = \frac{-32}{-2}[/tex] [tex]|4x + 12| = 16[/tex]Step 2: Solve absolute value.
We know either 4x + 12 = 16 or 4x + 12 = -16.1st Possibility:
4x + 12 = 164x + 12 - 12 = 16 - 12 (Subtract 12 from both sides)4x = 44x/4 = 4/4 (Divide both sides by 4)x = 12nd possibility:
4x + 12 = -164x + 12 - 12 = -16 - 12 (Subtract 12 from both sides)4x = -284x/4 = -28/4 (Divide both sides by 4)x = -7Therefore, the answer is x = 1, x = -7.

are 9 and 1/9 reciprocals?
Answer:
yes
Step-by-step explanation:
9 can be represented as 9/1, which is the reciprocal of 1/9.
Answer:
yes, they are
Step-by-step explanation:
Since a reciprocal is basically an inverse fraction,
9 is also known as 9/1
whn inverted, you get 1/9.
the same applies vice versa
1/9 --> 9/1
therefore, making then reciprocals

Answer:
417,808
Step-by-step explanation:
original weight = x
A 27% decrease is the same as multiplying by 0.73
27% = 0.27
1 - 0.27 = 0.73
x × 0.73 = 305,000kg
To find x, divide 305,000kg by 0.73
305,000 ÷ 0.73 = 417,808.2192 ≈ 417,808
Find the value of y+1 given that 2y+8=4.
Answer:
[tex]2y + 8 = 4 \\ 2y = 4 - 8 \\ 2y = - 4 \\ y = \frac{ - 4}{2} \\ y = - 2 \\ y + 1 = - 2 + 1 \\ \boxed{y + 1 = - 1}[/tex]
Therefore, the value of (y+1) is -1
(y+1) = -1 is the right answer.please explain the problem to me step by step
[tex] \frac{4y}{9} - \frac{2y}{3} = 10 \\ = > \frac{4y - 6y}{9} = 10 \\ = > \frac{ - 2y}{9} = 10 \\ = > y = 10 \times \frac{9}{ - 2} \\ = > y = - 5 \times 9 \\ = > y = - 45[/tex]

Identify the segment bisector of —
XY
Answer:
line n
Step-by-step explanation:
Line 'n' is the segment bisector.
We have a line segment XY given in figure.
We have to identify its segment bisector.
Define Segment bisector.A segment bisector divides a line segment into two equal parts.
According to the question, we have -
Line Segment XY and its Mid - Point M. It can be seen that the line 'n' is the segment bisector of the segment XY.
Hence, line 'n' is the segment bisector.

Answer:
Continuous graph:
- The height of a plant as it grows
- Amount of fuel and distance traveled.
Discrete graph:
- Number of students per teacher
- Amount of chairs for each table
Step-by-step explanation:
In mathematics "discrete" means specific points that do not possess a continuous line but only the plotting of points above certain integer values. On the other hand, the word "continuous" in mathematics would be a graph that has a constant smooth line that lacks jumps between values and sometimes decimal numbers.
"The number of students per teacher" would be discrete as the amount of students per teacher would be a fixed integer value.
"The height of a plant as it grows" would be continuous as the height of the plants increases the longer it grows. This would be represented by a straight continuous line.
"Amount of fuel and distance traveled" would be continuous as the amount of fuel used correlates with the distance traveled, which can be represented with a continuous line.
"Amount of chairs for each table" would be discrete as it would be a set integer value for the amount of chairs at each table, not a continuous line.

What re linear angles
Answer:
In geometry, a linear pair of angles is a pair of adjacent angles formed when two lines intersect each other. The linear pair of angles are always supplementary as they form on a straight line. In other words, the sum of two angles in a linear pair is always 180 degrees.
