y = 8-5x
Step-by-step explanation:
When two lines are parallel, it means their gradients are the same.
from the given equation
y = 9-5x
and comparing with the general equation of a line
y = mx+c, where m is the gradient, and c is the <em>y-intercept, </em>
m = -5
you can form a line parallel to that using the points (0,8)
(y-8)/(x-0)= -5
this would give you
y = 8-5x
Answer:
x - a smaller number
(x+1) - a larger number
3(x+1) - 2x = 34
3x + 3 - 2x = 34
x= 31
(x+1) = 32
Step-by-step explanation:
The greatest value of y is 2y+3=11 => y=4
Answer:
around 8 or 8.5 miles a day for 7 days
Step-by-step explanation:
60 divided 7 equals 8.5
The inverse of function f(x) = 9x+7 is f-1(x) = x/9 - 7/9
<h3>How to determine the inverse of the function?</h3>
The function is given as:
f(x) = 9x + 7
Express f(x) as y
y = 9x + 7
Swap the positions of x and y in the above equation
x = 9y + 7
Subtract 7 from both sides
9y = x - 7
Divide through by 9
y = x/9 - 7/9
Express as an inverse function
f-1(x) = x/9 - 7/9
Hence, the inverse of function f(x) = 9x+7 is f-1(x) = x/9 - 7/9
