Answer:
y = -5/7x - 55/7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
Slope <em>m</em> = -5/7
Random point (-4, -5)
y = -5/7x + b
Step 2: Find y-intercept <em>b</em>
-5 = -5/7(-4) + b
-5 = 20/7 + b
b = -55/7
Step 3: Write linear equation
y = -5/7x - 55/7
Answer:10.51inches
Step-by-step explanation:
circumference=66
Radius=circumference ➗ (2xπ)
Radius=66 ➗ (2x3.14)
Radius=66 ➗ 6.28
Radius=10.51inches
Answer:
B
Step-by-step explanation:
when we factor completely, we take a look at what is the biggest common factor of 7x³y⁴ and 7x²y⁵. In this case it is 7x²y⁴.
7x³y⁴-7x²y⁵ = 7x²y⁴(x-y) which is B.
Answer:
C. 14 feet
Step-by-step explanation:
Cos (60) = Adjacent / Hypotenuse
Cos (60) = 7/x
x = 7 / Cos(60)
x = 7 / 0.5
x = 14
Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
