what is -21.6 simplified?

Answer:

-28

Step-by-step explanation:

y/3-x = x+9

x=5

=>y/3-5=5+9

=>y/-2=14

=>y = - 28

Answer:

[tex]9.25[/tex]

Step-by-step explanation:

So we have the equation:

[tex]15-2(3-2x)=46[/tex]

First, distribute the -2:

[tex]15-2(3)-2(-2x)=46[/tex]

Multiply:

[tex]15-6+4x=46[/tex]

Subtract:

[tex]9+4x=46[/tex]

Subtract 9 from both sides:

[tex]4x=37[/tex]

Divide both sides by 4:

[tex]x=37/4=9.25[/tex]

And we're done!

answer is v=5

Step-by-step explanation:

10v-3v=7v

7v=35

v=35/7

v=5

Answer: [tex]v=5[/tex]

Simplify both sides of the equation

[tex]10v+-3v=35[/tex]

[tex](10v+-3v)=35[/tex] (Combine Like Terms)

[tex]7v=35[/tex]

Divide both sides by 7

[tex]7v/7=35/7\\v=5[/tex]

Answer:

-27

Step-by-step explanation:

(g+ 12) = 5(9 - 12)

g = 45 - 60 - 12

g = - 27

Answer:

g = 3

Step-by-step explanation:

- (g+ 12) = 5(9 - 12)     (remove parentheses by distributive property. See attached for reference)

g(-1) +  12(-1) = 9(5) -12(5)

-g - 12 = 45 - 60

-g - 12 = -15    (add 12 to both sides)

-g = -15 + 12

-g = -3   (multiply both sides by -1)

g = 3

Answer:

Answer:

x = 2

Step-by-step explanation:

Five to the power of quantity nine minus three x equals one hundred and twenty five.

----------------------

Plus a negative value becomes subtraction:

-12 + -23 = -12 -23 = -35

Let's try some integer values of x to see what volumes we get

We do not get 15 as a result in that list above. So there are no integer solutions to x^3 = 15

In other words, the value [tex]\sqrt[3]{15}[/tex] is not an integer.

Answer:

ahhhhhhhhhhhhh

Step-by-step explanation:

Answer:

  see below

Step-by-step explanation:

A graphing calculator is useful for this.

__

To find the x-intercept, set y=0 and solve for x:

  0 -3x = 12

  x = -4 . . . . . . divide by -3

To find the y-intercept, set x=0 and solve for y:

  4y - 0 = 12

  y = 3 . . . . . . divide by 4

Plot the x- and y-intercepts on their respective axes and draw a line through them.

Utilize PEMDAS to solve the problems.

[tex]\frac{-44.288-31.6}{-3.1(6-1.2)}[/tex]

[tex]\frac{-75.888}{-3.1(4.8)}[/tex]

[tex]\frac{-75.888}{-14.88}[/tex]

[tex]5.1[/tex]

Hope this helps.

頑張って!

Answer:

5.1

Step-by-step explanation:

first you subtract -44.288 - 31.6= -75.888

then subtract 6-1.2= 4.8

then multiply -3.1x4.8= -14.88

then divide -75.888/-14.88= 5.1

Answer:  The distance is about 9.43

Step-by-step explanation:

To find the distance between these numbers find the difference in the x and y values then square them and add them together and finally find the square root of the number you got after adding them.

-5 - 0 = -5

-6 - 2 =  -8

-5^2 + -8^2 = d^2   where d is the distance

25 + 64 = d^2  

89 = d^2

d = [tex]\sqrt{89}[/tex]

d= 9.43

Answer:

  x = -7y/(4 +5y)

Step-by-step explanation:

You can treat y as though it were a constant. As in any 2-step linear equation, you separate the variable term(s) from the constant term, then divide by the coefficient of the variable.

  4x +5xy = -7y . . . . . subtract 7y

  x(4 +5y) = -7y . . . . . factor out x, so we can see its coefficient

  x = -7y/(4 +5y) . . . . divide by the coefficient of x

Step-by-step explanation:

Answer:

10020

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the points R(-4, 5) and S(2, -1), to get the distance between the points, we will use the formula;

D = √(x2-x1)²+(y2-y1)²

Given x1= -4, y1 = 5, x2 = 2 and y2 = -1

RS = √(2-(-4))²+(-1-5)²

RS = √(6)²+(-6)²

RS = √36+36

RS = √72

RS = √2×36

RS = 6√2units

To get the midpoint, we will use the formula M(X,Y) = (x1+x2/2, y1+y2/2)

(X,Y) = (-4+2/2, -1+5/2)

(X,Y) = (-2/2, 4/2)

(X,Y) = (-1,2)

Hence the midpoint is (-1,2)

To get a point P 1/3 of the distance of RS, we will multiply 1/3 with the the distance RS as shown

P = 1/3 × 6√2

P = 2√2

Answer:A=8

Answer: c

Step-by-step explanation:

Answer:

Step-by-step explanation:

To get the length of segment HJ if H lies at (-1,7) and J lies at (8,-5)​, we will use the formula for calculating the distance between two points as shown;

D = √(x₂-x₁)²+(y₂-y₁)²

From the coordinates x₁ = -1, y₁ = 7, x₂ = 8, y₂ = -5

HJ = √(8-(-1))²+(-5-7)²

HJ = √(8+1)²+(-12)²

HJ = √81+144

HJ = √225

HJ = 15

Hence the length of segment HJ is 15 units
