Y = 1/4x....slope here is 1/4. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, " flip " the number and change the sign. So the negative reciprocal for our perpendicular line is -4.
y = mx + b
slope(m) = -4
(2,-5)...x = 2 and y = -5
now we sub and find b, the y int
-5 = -4(2) + b
-5 = -8 + b
-5 + 8 = b
3 = b
so ur perpendicular equation is : y = -4x + 3
Answer:
15 degrees, 75 degrees
Step-by-step explanation:
Call the first angle's measurement m
∠
1
.
The second angle is 5 times this, or 5
(
m
∠
1
)
.
Since the two angles are complementary (have a sum of 90
˚
), we can relate the two angles him as follows:
m
∠
1
+
5
(
m
∠
1
)
=
90
6
(
m
∠
1
)
=
90
m
∠
1
=
15
Since m
∠
2
is 5
times this, m
∠
2
=
15
×
5
=
75
.
I'M NOT TO SURE ABOUT THIS ANSWER BUT I HOPE THIS CAN HELP SOME PEOPLE.
F(4)=6(4) +3
= 24+3=27
F(4)=27.
Answer:
55.56 or 55 5/9
Step-by-step explanation:
To find the time it takes to type a report, you need to divide the number of words in the report by the words the typist can type in a minute.
2500/45 = 55.56
It takes 55.56 minutes or 55 5/9 minutes to type a 2500 word report.
