These Algebraic Expressions Are Not Equivalent. Explainwhy They Are Not Equivalent.+ 8x X2 - 6x2x 2xx2-1

Answers

Answer 1

Answer:

If you simplify the first expression, you will not get the second expression. In the first expression, the x2 terms have coefficients of 1 and –1 and, when combined, the result is 0. Also, the x terms have coefficients of 8 and –6 and, when combined, the result is 2. Finally, the constant from the first expression is not in the second expression.

How do i solve this slope of a line from a graph?​

Answers

Answer:

How you solve it is you pick two points on a line and figure out their coordinates. Determine the difference in the y-coordinates of those two points. Then you also do the same thing with the x-coordinates. Then you divide the difference in the Y and X coordinates .

How do you solve
8.4-6.8=-3.2y+16.4

Answers

Answer:

  y = 4.625

Step-by-step explanation:

Subtract 16.4 from both sides and collect terms.

  8.4 -6.8 -16.4 = -3.2y +16.4 -16.4

  -14.8 = -3.2y

Divide both sides by -3.2.

  -14.8/-3.2 = (-3.2y)/-3.2

  4.625 = y

The solution is y = 4.625.

Answer:

y=4.625

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

X+Y=4.25
16.90X+4Y=36.35
What are the values of X and Y

Answers

Answer:

Y = 2.75X = 1.5

Step-by-step explanation:

X+Y=4.25

16.90X+4Y=36.35

That means that;

X = 4.25 - Y

Substituting X into the second equation is;

16.90 * (4.25 - Y) + 4Y = 36.35

‭71.825‬ - 16.90Y + 4Y = 36.35

‭71.825‬ - 12.90Y = 36.35

‭71.825‬ - 36.35 = 12.90Y

Y = ‭35.475‬/12.90

Y = 2.75

X = 4.25 - Y

= 4.25 - 2.75

= 1.5

From the computation done, the value of X is 2.75 and Y is 1.5.

The following information can be depicted:

X + Y=4.25 .... i

16.90X + 4Y=36.35 ..... ii

From equation i

X = 4.25 - Y

We'll substitute X into the second equation and this will be:

16.90(4.25 - Y) + 4Y = 36.35

‭71.825‬ - 16.90Y + 4Y = 36.35

‭71.825‬ - 12.90Y = 36.35

Collect life terms

‭71.825‬ - 36.35 = 12.90Y

Y = ‭35.475‬/12.90

Y = 2.75

Since X = 4.25 - Y

X = 4.25 - 2.75

X = 1.5

Adjacent angles that form a linear pair are supplementary angles. True or false?

Answers

Answer:

FALSE

Step-by-step explanation:

Answer:

Step-by-step explanation:

It's true. If you have a straight line and you put the endpoint of a ray on that line and let the ray go in the direction it is pointing, 2 angles will be formed unless the ray is part of the line.  

The way the question is worded, you have a linear pair which means there are 2 distinct angles whose vertex is on a line.

That's the very definition of supplementary.

Write an equation in slope-intercept form for the line that passes through (−2, 3) and is parallel to
the line with the equation 3x + 2y = 6.

Answers

y= (-3x+6)2

For parallel lines, slopes are the same,

y = mx + c

Substitute the values,

3 = (-3/2)(-2) + c

3=3 + c,

c = 0

Thus, the equation is y= -3/2x
