2. Simplify the expression 3(x - 6) + 3(8) *

Answer:

No solutions

Step-by-step explanation:

Simplify both sides of the equation as much as possible:

9r + 5 - 4 = 4r + 5r - 12

9r + 1 = 9r - 12

Both sides have "9r" which when cancel out, leave the equation as:

+1 = -12

This means there are no solutions.

Answer:

blue

Step-by-step explanation:

270° moves by 3 quadrants

Answer:

Blue

Step-by-step explanation:

Rotate 1/2 circle (180°) counterclockwise and you go through the yellow to the green.

Go another 1/4 circle (90°) and you get to the blue.

180° + 90° = 270°

Answer:

total -70

Step-by-step explanation:

x =18

y=-28

Z = -60

An Arithmetic series: 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)

The Total value is =  -70

x = 18

y = -28

Z = -60

An Arithmetic series: 14 + 6 + (–2) + (–10) + (–18) + (–26) + (–34)

1st an 2nd element difference is = 14 - 6 = 8

2nd and 3rd element difference is = - 6 - 2 = -8

3rd and 4th element difference is = - 2 + 10 = 8

4th and 5th element difference is = -10 + 18 = 8

The difference (x,y and z) is 8 and also it's negative because the series is lowering the previous value.

Now, Proof of x,y and z = - 8

14 - 8 = 6

6 - 8 = - 2

- 2 - 8 = - 10

- 10 - 8 = - 18

- 18 - 8 = - 26

-26 - 8 = -34

Therefore, The value is = total -70

x = 18

y = -28

Z = -60

Hello! :)

The function pictured is a straight line, so it has a constant slope for all x values.

A function that has the same slope on its domain and when graphed is a straight line is a linear function.

Answer:

20 gallons of 15% solution must be mixed with 5 gallons of 40% solution.

Step-by-step explanation:

40% of 5 gallons is 2 gallons of sugar

x represents the number of gallons of solution to be added.

15% of x is sugar.

The total amount of sugar must be equal to 20% of the final mixture.

The end mixture will be x + 5 gallons

Change percent to decimal for the equation:

.2(x +5) = .15x +2

.2x +1 = .15x +2

.2x - .15x = 2 -1

.05x = 1

x = 20

Check:

.2(20 +5) = .15(20) +2

.2(25) = 3 + 2

5 = 5 true

This means that adding 20 gallons of the 15% solution is adding 3 gallons of sugar [along with 17 gallons of water] to the 2 gallons of sugar in the original mixture.

20% of the 25 gallons, 5 gallons, of the final mixture is sugar. 80% [ 3+17 = 20 gallons] is water.

Answer:

x=−7.974656,0.038604

Step-by-step explanation:

4x4+13x3−124x2+212x−8=0

Brainleist please

The possible rational solutions for the given equation are x= −7.974656 and 0.038604.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is [tex]4x^4+13x^3-124x^2+212x-8=0[/tex].

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Substitute x= ±1, ±1/2, ±1/4, ±2, ±4, ±8 in the given equation and verify

When x=1,

[tex]4(1)^4+13(1)^3-124(1)^2+212(1)-8=0[/tex]

⇒ 4+13-124+212-8=0

⇒ LHS ≠RHS

When x= -1

[tex]4(-1)^4+13(-1)^3-124(-1)^2+212(-1)-8=0[/tex]

⇒ 4-13-124-212-8=0

⇒ LHS ≠RHS

When x=1/2

[tex]4(\frac{1}{2} )^4+13(\frac{1}{2} )^3-124(\frac{1}{2} )^2+212(\frac{1}{2} )-8=0[/tex]

⇒ 1/4 +13/8 -31+106-8=0

⇒ LHS ≠RHS

When x=-1/2

[tex]4(-\frac{1}{2} )^4+13(-\frac{1}{2} )^3-124(-\frac{1}{2} )^2+212(-\frac{1}{2} )-8=0[/tex]

⇒ 1/4 -13/8 -31-106-8=0

⇒ LHS ≠RHS

Similarly Find every combination of ±p/q, where p is a factor of the constant and q is a factor of the leading coefficient.

Here, x= −7.974656 and 0.038604

Therefore, the possible rational solutions for the given equation are x= −7.974656 and 0.038604.

sorry, but I dont know the answer

Answer:

Ok, so this is a word game, basically. The answer would be no, he is not correct BECAUSE...⬇

Step-by-step explanation:

It looks to be asking "Is Jesse correct in saying that he has EXACTLY one liter left?" That would be a no because even though 10L-7L= 3L, the problem asks if he does have exactly ONE liter left, and Jesse says he DOES. But, according to my little equation above, if he drank 7L, he would have 3L left, NOT 1L. Soo, my answer would be "No, Jesse is not correct because 10L-7L=3L and if he says there is 1L left, he would not be correct because there are 3L left." Hope that helps!

Step-by-step explanation:

Answer:

Hey kroy21; the answer is 23°.

Step-by-step explanation:

Angle YAO and angle KAT are both complementary to angle OAK.

Angle OAK= 90°- Angle YAO

                  = 90° - 23°

                  = 67°

Then:

Angle KAT= 90° - Angle OAK

                 =90° - 67°

                 =23°

Answer:

The points are: (16.12,0),(-8.12,0).

Step-by-step explanation:

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

[tex]ax^{2} + bx + c, a\neq0[/tex].

This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:

[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

Distance between two points:

Suppose we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Find all points on the x-axis that are 14 units from the point (4, -7).

Being on the x-axis mean that they have y-coordinate equal to 0, so the point is (x,0).

The distance is 14. So

[tex]\sqrt{(x-4)^2+(0-(-7))^2} = 14[/tex]

[tex]\sqrt{x^2 - 8x + 16 + 49} = 14[/tex]

[tex]\sqrt{x^2 - 8x + 65} = 14[/tex]

[tex](\sqrt{x^2 - 8x + 65})^2 = 14^2[/tex]

[tex]x^2 - 8x + 65 - 196 = 0[/tex]

[tex]x^2 - 8x - 131 = 0[/tex]

So [tex]a = 1, b = -8, c = -131[/tex]

[tex]\bigtriangleup = (-8)^{2} - 4(1)(-131) = 588[/tex]

[tex]x_{1} = \frac{-(-8) + \sqrt{588}}{2} = 16.12[/tex]

[tex]x_{1} = \frac{-(-8) - \sqrt{588}}{2} = -8.12[/tex]

The points are: (16.12,0),(-8.12,0).
