Step-by-step explanation:
Answer:
y=mx+b
Step-by-step explanation:
m=slope B= y intercept
(2-2) y=(mx+b)
Answer:
4.4 t = 13.2
t = 13.2 / 4.4 = 3
t = 3
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
If ΔMNO ≅ ΔPST, their corresponding sides must also be ≅(congruent).
NO is corresponds to TS, thus sides NO and side TS are ≅.
=> 20 = 3x - 7
=> 3x = 27
=> x = 9
Answer:
see explanation
Step-by-step explanation:
Given x varies directly as y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition x = 9 when y = 4
k =
=
= 2.25
x = 2.25y ← equation of variation
When y = 8, then
x = 2.25 × 8 = 18
