D(x) = 2x − 4 and c(x) = 2x − 7 Find (d + c)(3)

Mathematics

Rasek [7]1 year ago

Answer: 1

Step-by-step explanation:

Find (d + c)(3) The x value is 3 so you plug in 3 for the x's in the equation

d(x) = 2x − 4

d(3) = 2(3) - 4

d(3) = 2

c(x) = 2x − 7

c(3) = 2(3) - 7

c(3) = -1

Now you plug in the value of d and c into your original equation which is (d+c)(3)

(2 + (-1)) = 1

This means (d+c)(3) = 1

A trapezoid is generally defined as a quadrilateral with <em>exactly one</em> pair of parallel sides. That means a rhombus is not a trapezoid. (No)

A parallelogram has two pairs of parallel sides. (No)

A rectangle may not have equal-length sides, so a rectangle may not be a rhombus. (No)

A rectangle has two pairs of parallel sides, so a rectangle is always a parallelogram. (Yes)

The population of a town is 81,712 and declines continuously at a rate of 4.1% each year. What is the approximate population of
Ganezh [65]
Data:

P (Final population) = ?
Po (Initial population) = 81712
r (rate) = 4,1% = 0,041
t (time in years) = 17

P = Po - (Po*r*t)
P = 81712 -(81712*0,014*17)
P = 81712 - 56953.264
P =24758.736
\boxed{P \approx 24759}

Answer:
B) 24759
