The 3 consecutive numbers are 41, 42, and 43 : 41+42+43= 126
Answer:
y = - 2x + 8
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 9 ← is in slope- intercept form
with m =
given a line with slope m then the slope of a line perpendicular to it is
= - = - = - 2
y = - 2x + c ← is the partial equation
to find c substitute (3, 2 ) into the partial equation
2 = - 6 + c ⇒ c = 2 + 6 = 8
y = - 2x + 8 ← equation of perpendicular line
Answer:
71.8° F
Step-by-step explanation:
Given 75° and 4 times 0.8° drop = 3.2°, so the temperature is 75° - 3.2°
= 71.8° F
Answer:
BC=23
Step-by-step explanation:
Use sine rule:
x/sinX=y/sinY
BC/sinA=AB/sinC
BC/sin61=9/sin20
BC=26.3142396015*sin61
BC=23.0149525338
Answer:
43
Step-by-step explanation:
7x+ 3 - 2x x=8
Replace x with 8
7(8)+ 3 - 2(8) multiply first
56+ 3 - 16 then solve
43 is the overall answer
