Find the slope-intercept form of the equation of the line that passes through the points (2,-5)

n200080 [17]

Answer:

-3

Step-by-step explanation:

(

$(2,-5)=(x_1,y_1) \\ (4,-11)= (x_2,y_2) \\$

$m = \frac{y_2 - y_1}{x_2 - x_1} \\$

Plug in values into the given equation

$m = \frac{ - 11 - ( - 5))}{4 - 2} \\ \\ m = \frac{ - 11 + 5}{2} \\$

Simplify

$m = \frac{ - 6}{2} \\ m = - 3$

A book store has twice as many history books as science books. The store has 81 history and science books altogether how many of

atroni [7]

let h= history books

science books = s

h=2s there are 2 times as many history as science so to get them equal we double the science

h+s=81 there are 81 total history and science books

2s+s=81 substitute 2s for h in the above equation

3s = 81 combine like terms

s = 27

There are 27 science books

h=2s

h=2(27)

h=54

there are 54 history books

A skateboard ramp has a height of 3 feet and a horizontal of 7 feet. What is the angle of 0 of the ramp?

lisov135 [29]

When we have a right triangle with sides and angles, we use basic trigononemetry. Since we know the vertical leg (height of ramp) and horizontal leg (base length of ramp), we use the inverse tangent function to find the angle.

θ = tan-1(height of ramp / base of ramp) θ = tan-1(2.5 / 6) θ = tan-1(5 / 12)
