PLEASE HELP ME IM IN NEEDD !

-3 - (-1) = -2     or:  -3 + 1= - 2

4- (-4) = 8       or:   4 +4 = 8

Step-by-step explanation:

subtracting a negative, is the same thing as adding a positive. so whenever you see a subtraction sign along with a number in parenthesis that has a negative sign, you add the numbers together

y -5 = (-1/4)(x + 8)

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
