Solve: -x + 4 = -9 and -3x + 7 = 1

Answer: 3000 Kelvin

Step-by-step explanation

Let the surface temperature of the red giant star = x

Surface temperature of a white dwarf star = 4x

4x = 1.2 × 10^4 K

    = 1.2 × 10,000 K

    = 12,000 K

4x = 12,000 K

x = 12000 ÷ 4

  = 3,000 K

Answer C:  112

Step-by-step explanation:

The product of two negative numbers is a positive number.  Thus, we omit possible Answers A and B.  Using mental math or a calculator, find 8 • 14; it is 112 (Answer C).

Answer:

70-79 is the answer

Step-by-step explanation:

Answer:

A. f(x+3)

Step-by-step explanation:

The vertex form is y=a(x-h)^2+k. To move left, your 'h' value has to be negative, so in this case, it'd be -3, but wait. Since it already tells you to subtract the 'h' value, subtracting -3, (-(-3), would be the same as adding 3. So inside the form, it has to be (x+3) to make sense. A is the correct answer.

B is incorrect because that just shifts the function 3 units up.

C is incorrect because that shifts the function 3 units down.

D is incorrect because that shifts the function 3 units right.

Hope this helps.

Perimeter is 2/7+2. which is 2.2

Step-by-step explanation:

Im not completely sure, but hope this helps XP

Answer:

You have to add the perimeter of [tex]x^{2}[/tex] + 4 and 5[tex]x^{2}[/tex] + 1.

Step-by-step explanation:

Remember when it says "area" that means multiply but "perimeter" means addition.

Answer:

Tiffany just got an aquarium for her rare turtle. She wants to fill it with water but it came without the volume measurement on it. She measures and finds aquarium's length is 30 inches, width is 12 inches, and height is 18 inches. How many cubic inches of water does she need?

Step-by-step explanation:

The formula for right rectangular prism is Length×Width×Height

30×12×18 = 6480

So she needs 6,480 in³ of water

4: 102*

5: 47*

6: 43*

7: 35*

Step-by-step explanation:

1. Alternate Interior Angles are angles made and formed when two parallel or non-parallel lines are intersected by a transversal

2. Corresponding Angles are angles that are in the same position relative to lines intersected by a transversal

3. Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

4. Using the Corresponding Angle formula, we know that angle x is equivalent to the corresponding angle above it

5. Using the Alternate Exterior Angle formula, we know that the angle y is equal to the 47* angle

6. Supplementary Angles are two angles whose measures add up to 180 degrees.

7. Using the Alternate Exterior Angle formula, we know that the angle w is equal to the 35* angle

Answer:

18 x 10 x 9 = 1620

+

9 x 5 x 24 = 1080

= 2700m3

Answer:

2700

Step-by-step explanation:

You first find the area of each shape:

1st: 9*5*24= 1080

2nd: 18*10*9= 1620

Then you add the two together:

1080 + 1620 = 2700

That is your answer.

Answer:

14 meters²

Step-by-step explanation:

Since the formula to find the diameter is [tex]d=2r[/tex], we need to first find the radius, which can be [tex]r=\frac{\sqrt{A\pi}}{\pi}[/tex] if we take the formula for the area of a circle and isolate the radius. After simplifying [tex]r=\frac{\sqrt{153.86\pi}}{\pi}[/tex] to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!
