Answer:
A
Step-by-step explanation:
To express 4/5 as a decimal, you divide 4 by 5. Here is long division image at the bottom. You can just input it into a calculator (4 divdie 5) or notice that 4/5 = 8/10 = 0.8.
I hope this helps!
Step-by-step explanation:
the line equation
y = ax + b
gives us slope (a) and y-interception (b).
4x + 3y = 5
3y = -4x + 5
y = -4/3 × x + 5/3
the slope of the original line is therefore -4/3.
a perpendicular slope flips x and y upside-down and flips the sign.
so, the perpendicular slope of -4/3 is 3/4.
the desired line looks like
y = 3/4 × x + b
b we get by using the given point and its coordinates :
-3 = 3/4 × 3 + b = 9/4 + b
-12/4 = 9/4 + b
b = -21/4
so our full line equation is
y = 3/4 × x - 21/4
or
4y = 3x - 21
-3x + 4y = -21
Answer:
x > 8

Answer:
y = 5x
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportionality
To find k use the condition that y = 30 when x = 6
k =
=
= 5
y = 5x ← equation of proportion
The distance will be 11.1803.
