Answers

Answer:

The slope-intercept form: y = mx + b

m - a slope

b - y-intercept

We have a slope m = 1/4. Substitute: y = 1/4 x + b

We know, the line passes through point (8, 3) → x = 8, y = 3.

Put the values of x and y to the equation of the line:

1/4 · 8 + b = 3

2 + b = 3 |-2

b = 1

Answer: y-intercept is (0, 1)

Answer:

g(x) = (x-8)^2 - 5

Step-by-step explanation:

subtracting from x inside of the square translates the function to the right and adding to x inside of the square translates it to the left.

(x-8)^2 - 1  translates the function 8 units to the right

subtracting from the constant translates the function down and adding translates it up.

x^2 - 5 translates the function 4 units down

Therefore, (x-8)^2 - 5 translates the function 8 units to the right and 4 units down

A 20 ft tall ladder standing next to a statue casts a 12 ft shadow. If the statue casts a shadow that is 9 ft long then how tall is it?

Answers

Given that,

Length of the ladder = 20 ft

It casts a 12 ft shadow

To find,

If the statue casts a shadow that is 9 ft long then how tall is it?

Solution,

Let the ladder be x ft tall.

20 ft tall ladder = 12 ft shadow

9 ft tall ladder =

This is also coincidentally what the right side of this graph looks graphically. However, the line of 3x does continue past x=0, so the other side of this graph, -3x, fits this better.

a acute and scalene. c. right and isosceles.
b right and scalene. d. obtuse and isosceles.

Answers

Answer:

C. Right and isosceles

Explanation:

Since two sides of the triangle are equal in length ([tex]DE[/tex] and [tex]DF[/tex]), this means that the triangle is an isosceles triangle. Since [tex]EF[/tex] is the hypotenuse of this triangle, it also means that the triangle is a right-angle triangle (the hypotenuse refers to the longest side of a right triangle). Therefore, we can conclude that ΔDEF is right and isosceles.
