What is the initial value of the equation shown?y = −7x − 6

A. −13
B. −7
C. −6
D. −1

Answers

Answer:

Option C  -6

Step-by-step explanation:

we  know that

The initial value is the value of the function when the value of x is equal to zero

The initial value is the y-intercept of the function

In this problem we have

y=-7x-6 -----> equation of the line into slope intercept form

therefore

m=-7 -----> the slope

b=-6 ----> the y-intercept

The initial value is -6

Mario travels 180 miles in 2.5 hours of Mario travels at the same right how far can Mario travel in 12.5 hours

Answers

12.5/2.5=5
5x180= 900

Answer:

900 miles

Step-by-step explanation:

well if you have 12.5 and you divide it by 2.5 you get 5. I do this because you need to find out how many time 2.5 goes into 12.5 so you can then multiply 180 by that number. 180*5=900

A line passes through the points (8, 7) and (5, 1). What is its equation in slope-intercept form?

Answers

Answer:

y=2x-9

Step-by-step explanation:

The slope is 2 and the y-intercept is -9

Answer:

y = 2x - 9

Step-by-step explanation:

Y2 - Y1/X2 - X1

7 - 1/8 - 5

6/3

= 2

y = 2x + b

1 = 2(5) + b

1 = 10 + b

-9 = b

y = 2x - 9

A firefighter is attempting to escape a burning building. If the window is of the man's apartment is 18 feet above the ground and the ladder is 25 feet long, what is the angle of elevation?

Answers

Answer:

37.75⁰

Step-by-step explanation:

Height of the building = 18 feet (vertical height)

Height of the ladder = 25 feet (Hypotenuse)

We solve this using tan θ = (adjacent)/(hypotenuse)

therefore θ = tan⁻¹ ((18)/(25))

θ (Angle of elevation) = 37.75⁰
