Answer 1

1. 1. 12a²b² , -7a²b² and 9a²b²

anwer ;

12a²b² - 7a²b² + 9a²b² = ( 12 - 7 + 9 )a²b²= 14 a²b²

2. 4x²y , -3xy² , -5xy² , 5x²y

answer ;

( 4x²y + 5x²y ) + (- 3xy² - 5xy² ) = (4 + 5)x²y + ( -3 - 5) xy² = 9x²y - 8 xy²

3. -10abc from 10abc

answer ;

10abc - ( -10abc ) = 10abc + 10abc = (10 + 10) abc 20abc

4. -5y from y²

answer ;

y² - ( -5y² ) = y² + 5y²= y² ( 1 + 5 ) = 6y²

the midpoint of (3 x, -2) and (-4, 5y) is (1,4). find x, -y​

Answers

Answer:

(x,-y): (2,-2)

Step-by-step explanation:

M=(x+x)/2,(y+y)/2

Given (1,4)=

[tex] \frac{3x - 4}{2} [/tex]

This implies:

[tex]1 = \frac{3x - 4}{2} [/tex]

[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]

In a similar way,

[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]

The question demanded (x,-y)

Hence(2,-2) is the answer

Rashid solves the following system of equations using the elimination method.

6x−5y=−31

5x+3y=10

What value does he correctly determine for x?

Enter you answer in the box. x =

Answers

Answer:

X = -1 & and for some additional information Y = -5

Step-by-step explanation:

6 x (-1) = (-6)

5 x (-5) = (-25)

(-6) - (-25) = (-31)

_____________

5 x (-1) = (-5)

3 x (-5) = (-15)

(-5) + (-15) = 10

Answer:

  x = -1

Step-by-step explanation:

Rashid may have used elimination to solve the problem, but we can use any method we like to find the correct value of x. One method we like is graphing. The attached graph shows the solution is (x, y) = (-1, 5), so we know Rashid found ...

  x = -1

__

If we go down Rashid's path, we multiply the first equation by 3 and add that to the second equation multiplied by 5. (This choice of multipliers results in a positive coefficient for x.)

  3(6x -5y) +5(5x +3y) = 3(-31) +5(10)

  18x -15y +25x +15y = -93 +50 . . . . . . eliminate parentheses

  43x = -43 . . . . . . . . . . . . . . . . . simplify

  x = -1 . . . . . . . . . . . . . . . . . divide by 43

S2x+3y=-12
(4x-4y=4

Answers

Answer:

I'll assume "S2x+3y=-12" is actually 2x+3y=-12 and that the question is to solve for x and y.

x = -(9/5)

y = -(14/5)

Step-by-step explanation:

2x+3y=-12

4x-4y=4

---

2x+3y=-12

8x+12y=-48  [Multiply the 1st equation by 4]

12x-12y=12   [Multiply the second equation by 3]

20x = -36     [Now we can add the two equations to remoce the y term]

x = -(36/20)  

x = -(9/5)       [The value for x]

====

2x+3y=-12        [Take either equation and s=use x=-(9/5) to find y]

2(-9/5)+3y=-12  

-(18/5) + 3y = -12

+ 3y = -12 + (18/5)

y = -4 + (6/5)

y = -(20/5)+(6/5)

y = -(14/5)          [This is the value of y that will work for both equations]

These equations both have the point (-9/5, -14/5) in common:  they intersect here.

This problem can also be solved by graphing each equation and finding the point they inersect on the graph (attached).

Find the slope between:
(4,5)
(3,5)

Answers

Answer:

If a line goes through both points, the slope of that line would be [tex]0[/tex].

Step-by-step explanation:

The slope of a line is equal to the ratio between the vertical change of this line "rise" and the corresponding horizontal change "run":

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}}\end{aligned}[/tex].

If a non-vertical line goes through two distinct points [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] where [tex]x_{0} \ne x_{1}[/tex], the vertical change (rise) would be [tex](y_{1} - y_{0})[/tex]. The corresponding horizontal change would be [tex](x_{1} - x_{0})[/tex]. Thus, the slope of that line would be:

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}}\end{aligned}[/tex].

In this question, [tex]x_{0} = 4[/tex] and [tex]y_{0} = 5[/tex] for the first point, whereas [tex]x_{1} = 3[/tex] and [tex]y_{1} = 5[/tex] for the second point.

The rise (vertical change) of this line from the first point to the second would be [tex](y_{1} - y_{0}) = 5 - 5 = 0[/tex]. The corresponding run (horizontal change) would be [tex](x_{1} - x_{0}) = 3 - 4 = -1[/tex].

Thus, the slope of this line would be:

[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}} \\ &= \frac{5 - 5}{3 - 4} \\&= \frac{0}{-1} \\ &= 0\end{aligned}[/tex].

In other words, the slope of this line is [tex]0[/tex]. Geometrically, a slope with a slope of [tex]0\![/tex] would be horizontal. The vertical coordinate of all points on such line would be the same ([tex]5[/tex] for points on the line in this question.)

In plane ABC the measure of angle A equals 42° the measure of angle B is five times the measure of angle C find the measure of angle B and the measure of angle C.

Answers

Step-by-step explanation:

I think what is meant in the triangle ABC we have the three angles.

the sum of all angles in a triangle is airways 180 degrees.

so,

180 = A + B + C

180 = 42 + B + C

now, we know also that

B = 5×C

so, we can use that above

180 = 42 + 5×C + C

138 = 6×C

C = 138/6 = 23 degrees

B = 5×C = 5×23 = 115 degrees

Divide 5 by 1,000 and round to the nearest whole number

Answers

Answer:

1

Step-by-step explanation:

5÷1000=0.005

0.005 ≈ 1 (1 is the nearest whole number)

Hope this helps!

The number 5 divided by 1,000 is approximately 0 when rounded to the nearest whole number.

To divide 5 by 1,000, we simply perform the division:

5 ÷ 1,000 = 0.005

Now, to round the result to the nearest whole number, we examine the first decimal place. Since it is less than 5, we round down to the nearest whole number.

Thus, the rounded result is 0.

Rounding is a process used to simplify numbers to a certain level of precision. When rounding to the nearest whole number, we look at the digit to the right of the decimal point (the first decimal place). If this digit is 5 or greater, we round up to the next whole number. If it is less than 5, we round down to the current whole number.

In this case, 0.005 is less than 0.5, so we round down to 0.
