Triangle ABC is congruent to triangle DFE. Find y.

kirza4 [7]

Angles D and A are equal (from the statement bc the name of triangle starts with A and D)

Now set an equation of the angles so
45 = 5y -10

Add 10 on both sides

55 = 5y
divide by 5

y = 11

As given;

2.52x10^7 people are living in <span>4.05x10^5 km^2 area. then for 1km^2, the number of people can be calculated as:
people in 1km^2 = (2.52x10^7) / (</span><span>4.05x10^5)
=0.62x10^2

Solve for a if the line through the two given points has the given slope.(a,5) and (1,−5),m=−2

Luba_88 [7]

slope (m) = (y₂ - y₁)/(x₂ - x₁)

-2/1 = (a - 1)/(5 -(-5))

-2 = (a - 1)/10

-20 = a - 1

-19 = a

Answer: a = -19

3x^2+17x-9/x+4 what is the quotient

zvonat [6]

Answer:

The quotient of given expression is (3x+5).

Step-by-step explanation:

The given expression is

$\frac{3x^2+17x-9}{x+4}$

The coefficients of dividend are 3,17 and -9.

Use synthetic division to divide $3x^2+17x-9$ and $x+4$ .

The bottom row represents the coefficient of quotient and remainder.

The given expression can be written as

$\frac{3x^2+17x-9}{x+4}=3x+5-\frac{29}{x+4}$

Therefore the quotient of given expression is (3x+5).
