Answer:

7) A

8) 1/2

9) 5000

Step-by-step explanation:

7)

(0, 0), (4, -10)

The line goes through point (0, 0), the origin, so its equation is of the form

y = mx, where m = slope

m = (-10 - 0)/(4 - 0) = -10/4 = -5/2

Equation: y = -5/2 x

Answer: A

8)

(0, 0), (2, 1)

The line goes through point (0, 0), the origin, so its equation is of the form

y = mx, where m = slope

m = (1 - 0)/(2 - 0) = 1/2

Equation: y = 1/2 x

Answer: 1/2

9)

The value of the house increases $5000 per year, so we multiply the number of years, x, by 5000 to find the increase after x years.

Equation: y = 5000x

Answer: 5000

We know that
∠ECD=∠ACB------> given in the problem
∠DEC=∠CAB------> 90°
so
∠EDC=∠ABC

therefore
triangles EDC and ABC are similar
<span>So
the ratio of the legs are equal</span>

 \frac{x}{9} = \frac{140-x}{81}  \\ 81*x=9*(140-x) \\ 81x+9x=1260 \\ 90x=1260 \\ x=14

AC=140-x \\ AC=140-14 \\ AC=126

the answer is
AC is equal to 126

Answer:

Area = 5x^2 +7x -26

Step-by-step explanation:

The area of the shaded region can be found if you substruct the small rectangle from the big one. The area of any rectangle is calculated if you multiply width and height.

In other words:

A_small = (x-3)(x-6) = x^2-9x +18

A_big = (2x+2)(3x-4) = 6x^2 -2x -8

A_big - A_small = (6x^2 -2x -8) - (x^2-9x +18)

= 6x^2 -2x -8 - x^2 + 9x -18

= 5x^2 +7x -26
