Answer: -9 degrees Fahrenheit

Step-by-step explanation:

Given: Temperature at 6:00 AM = -12 degrees Fahrenheit

Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit

Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

= -12+3 degrees Fahrenheit

= -9 degrees Fahrenheit

Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

Answer:

(72 divided by 6) + 6

Step-by-step explanation:

78 divided by 6 is 13. The question (72 divided by 6) + 6 does not equal to 13, it equals to 14, therefore (72 divided by 6) + 6 is not equivalent.

Answer:

x is less than -3 so it would be the top one

Step-by-step explanation:

Answer:

x < -3

Step-by-step explanation:

it must be less than -3 but not equal so x < -3 is the correct answer.

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

Answer:

x = 4

y = 5

Step-by-step explanation:

4x = x + 12

^(subtract x from both sides)^

3x = 12

^(divide both sides by 3)^

x = 4

3y = 15

(divide both sides by 3)

y = 5

Answer:

x=28°

Step-by-step explanation:

2x+3x-10+50=180

5x+40=180

5x=180-40

5x=140

x=140/5

x=28°

The angle measure of a triangle are shown in the diagram.

What is the value of x?

As, In a triangle measure of all three angles is always 180°.

[tex] \sf : \implies \angle A + \angle B + \angle C = 180\degree[/tex]

[tex] \sf : \implies 50\degree + (2x)\degree + (3x - 10)\degree = 180\degree[/tex]

[tex] \sf : \implies 50 + 2x + 3x - 10 = 180\degree[/tex]

[tex] \sf : \implies 40 + 5x = 180\degree[/tex]

[tex] \sf : \implies 5x = 180\degree - 40\degree[/tex]

[tex] \sf : \implies 5x = 140\degree[/tex]

[tex] \sf : \implies x = \cancel{\dfrac{140\degree}{5}}[/tex]

[tex] \sf : \implies x = 28\degree[/tex]

[tex] \large \underline{\boxed{\bf{x = 28\degree}}}[/tex]

Hence, value of x is 28°.

Answer:

3 rd one

Step-by-step explanation:

The conic section represented by the given equation is Circle.

Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.

Standard form of a circle is,

(x - h)² + (y - k)² = r²

where, (h, k) is the center of the circle and r is the radius of the circle.

Expanding, we get,

x² - 2hx + h² + y² - 2ky + k² = r²

x² - 2hx + y² - 2ky + (h² + k² - r²) = 0

The given equation is,

5x² – x + 5y² – 3y + 4 = 0

This is same as the standard form of the circle.

Hence the given equation is that of a circle.

Sample Response: Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator

Answer:

This is what it says to include in your response..." Each base has a negative exponent" and "Both powers should be in the denominator".

Step-by-step explanation:

This is the Exact sample response,

Each base must be treated separately. Since each base is raised to a negative exponent, they should both be in the denominator of the fractions. The simplified form of the expression has 1 in the numerator and r to the 8th power times s to the 5th power in the denominator.

Answer:

angle 1 is = 124 angle 2 is = 56

Step-by-step explanation:

supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.

Answer:

A

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2

Answer:

20, 68%, 0.687

Step-by-step explanation:

If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.
