Answer:
y=x+1
Step-by-step explanation:
rise of 1, run of 1, and y-intercept is one
Answer:
26.25 cm²
Step-by-step explanation:
The area of the shaded part is the area of the shaded triangle subtract the area of the white triangle.
Since the triangles are similar then the ratios of corresponding sides are equal.
let the height of the white triangle be h, then
=
( cross- multiply )
12h = 90 ( divide both sides by 12 )
h = 7.5
shaded area =
× 12 × 10 -
× 9 × 7.5 = 60 - 33.75 = 26.25 cm²
Answer:
x = 16/9
Step-by-step explanation:
81x - 122 = 22
81x = 144
x = 16/9
Answer:
i think the point is (2, -5)
Step-by-step explanation:
m = slope
y - y1 = m(x - x1)
replace:
y - (-5) = 3(x - 2)
simplify:
y + 5 = 3(x-2)
point:
y1, x1
replace:
-5, 2
