Your question has been heard loud and clear.
let the ratio be m:n
From section formula
(-3n + 4m)/(m+n) = 2
-3n + 4m = 2m+2n
5n = 2m
m/n = 5/2
m:n = 5:2
Answer:
y = -2x + 9
Step-by-step explanation:
The general shape of the equation is y = ax + b, you just have to find a and b.
b is simple, it is the y coordinate where the line crosses the y axis, i.e., b=9.
a is the slope of the line. This is the change in y when you take one step to the right. The change is -2.
Hence y = -2x + 9
3x+2y=11
y=5x-1
Substitute the y in the first equation:
3x+2(5x-1)=11
y=5x-1
3x+10x-2=11
y=5x-1
13x=13
y=5x-1
Now substitute the x to find the y:
x=1
y=5-1=4
Answer:
x = -3
Step by step explaination-
3(2(-3) + 4) = -6
23°F
Step-by-step explanation:
f=1.8c+32
f=1.8×-5 +32
= -9 +32
=23°F.
