Check your answer:

8-5(3)=-78-15=-7-7=-7

Answer 2

Answer:

A and C

Step-by-step explanation:

By letting x = 0 she is eliminating the terms in x , rather than simplifying

9x - 3x - 4 ← collect like terms

= 6x - 4

12x - 4 ← already in simplest form

5x + x - 4 ← collect like terms

= 6x - 4

Thus A and C are equivalent expressions

The average surface temperature of a red giant star is much cooler than that of a white dwarf star. Suppose a white dwarf has a surface temperature of 1.2 x 10*4 Kelvin (abbreviated K), which is 4 times the temperature of a red giant star. WHat is the surface temperature of the red giant star?

Answers

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

Answers

Answer:

4. 23

4. 206

5. 75 ft

7. 6 sections

8. 6 families

Step-by-step explanation:

4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23

4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206

5. Formula for area of triangle = 1/2 x base x height

So, it's 1/2 x 10 x 15 = 75

7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)

8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.

4. 3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.

X³ - 10. Substitute the X for 6. 6³-10= 216.

5. I'm not 100% sure but I believe that it is 75. I might be wrong.

Two lines, A and B, are represented by equations given below: Line A: y = x − 4 Line B: y = 3x + 4 Which of the following shows the solution to the system of equations and explains why? (1 point) a (−3, −5), because the point satisfies one of the equations b (−3, −5), because the point lies between the two axes c (−4, −8), because the point satisfies both equations d (−4, −8), because the point does not lie on any axis

Answers

Answer:

The answer is "C"

Step-by-step explanation:

Answer:

Answer C. This point lies between the two axes and its coordinates satisfy both equations

Step-by-step explanation:

Line A: y = x − 4

Line B: y = 3x + 4

Let's actually solve this system, using substitution: Equate

Line A: y = x − 4 to Line B: y = 3x + 4, obtaining:

x − 4 = 3x + 4

Subtract (x - 4) from both sides. Doing so yields

0 = 2x + 8, and so x = -4.

From Line A let's find y: Letting x = -4, we get: y = -4 - 4 = -8

and so the solution is (-4, -8). This matches Answer C. This point lies between the two axes and its coordinates satisfy both equations.
