Answer:
x = -8.5
Step-by-step explanation:
Let's rearrange the question to find x :)
-8x + 6x + 10 - 8 = 19
-2x + 2 = 19
-2 -2
-2x = 17
/-2 /-2
x = -8.5
Answer:
See below.
Step-by-step explanation:
1. 3 * 15 + 4 * 15 - 5 * 15
45 + 60 - 75
105 - 75
30
2. 3x + 4x - 5x
7x - 5x
2x
3. 3(x-2) + 4(x-2) - 5(x-2)
3x - 6 + 4x - 8 - 5x + 10
2x - 4
4. (I'm not typing that out)
7.5x + 19.5 + 10x + 26 - 12.5x - 32.5
5x+13

Answer: the domain of f(x)=2x+2 is all real numbers and the domain of g(x)=x^2 is (0, infinity)
Step-by-step explanation:
there is no horizontal asymptote given
In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.
In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.
(3963)^2 + b^2 = (4213)^2
b^2 = 2,044,000
b = 1430 miles.
The astronaut can see 1430 miles to the horizon.
Answer:
the truck will over load with 13 refrigerators and 8 pianos
Step-by-step explanation:
13 refrigerators is 2600 lbs
8 pianos is 4200 lbs
both added together is 6800 lbs
the truck can only hold 5900 so 13 refrigerators and 8 pianos is too heavy
