The formula for slope is (x2-x1)/(y2-y1).
we label the points accordingly:
(-7,3) as (x1, y1)
and
(4,-2) as (x2, y2).
now just plug it into the formula.
(-2-3)/(4-(-7))
(-5/11)
the slope is -5/11.
hope this helps! (:
Answer:
Width = 9 cm, length = 14 cm
Step-by-step explanation:
Width = w; Length = L
2(W+L) = 46, W+L = 23, W= 23-L
W*L = 126, (23-L)*L = 126
W = 9, L = 14
Answer:D 2 1/7
Step-by-step explanation: you can put 7 into 15 two times and that gives you 2 holes and you then have 1/7 leftover therefore you have 2 1/7.
Answer:
θ = 67.4°
Step-by-step explanation:
using the <u>SOHCAHTOA </u>method,
Here opposite is 12 cm, hypotenuse is 13 cm, adjacent is 5 cm.
Using the formula:
β = 67.4°
Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
