Answer:
See answers below
Step-by-step explanation:
Given the following functions:
r(x) = x - 6
s(x) = 2x²
r(s(x)) = r(2x²)
Replacing x with 2x² in r(x) will give;
r(2x²) = 2x² - 6
r(s(x)) = 2x² - 6
(r-s)(x) = r(x) - s(x)
(r-s)(x) = x - 6 - 2x²
Rearrange
(r-s)(x) = - 2x²+x-6
(r+s)(x) = r(x) + s(x)
(r-s)(x) = x - 6 + 2x²
Rearrange
(r-s)(x) = 2x²+x-6
The length and width of the terrace are 15 feet and 6 feet respectively.
The area of the terrace is 90 ft²
The scale of the plan is 2 inches : 6 feet.
Therefore, 2inches represents 6 feet.
According to the drawing;
- length = 5 inches
- width = 2 inches
Therefore,
- length of the terrace = 5 × 6 / 2 = 30 / 2 = 15 feet
- width of the terrace = 2 × 6 / 2 = 12 / 2 = 6 feet
The area can be found as follows:
<h3>Area of a rectangle:</h3>
where
l = length
w = width
Therefore,
area = 15 × 6 = 90 feet²

Answer:
Ivette is wrong and by a lot. The spaceship should be 23.59 feet high
Step-by-step explanation:
The relationship between the spaceship's height and width = 184 feet : 78 feet ≈ 92 : 39 ≈ 9.2 : 3.9. This means that for every 3.9 feet wide, the cake should be 9.2 feet high.
In this case, the spaceship is 10 feet wide, so it should be (10 / 3.9) x 9.2 = 23.59 feet high.
When you make scale drawings or scale cakes, you must keep the same proportions as the original model.
Answer:
Infinite solutions
Step-by-step explanation:
x + 4y = 7 --------------(I)
8y = 14 - 2x
⇒ 2x + 8y = 14 -----------(II)
So, infinite solutions
