We can rearrange 3x+y=9 to look more conventional by subtracting 3x from both sides and making it y= -3x+9.
Now we want to find a line that is parallel to this and goes through the point (0,-4). We know that -3 is the slope. With this in mind, if we want the other line to be parallel then it must have the same slope so that they never intersect. This gives us one of the numbers we need for the second line.
This means our second equation is looking like; y= -3x+b. This means we need to find b (the y-intercept) but we are also given a point it must go through and this is (0,-4). We simply plug this in into our new equation we need to solve and we get ; -4 = -3(0) + b . "since 0 is the x and -4 is the y" . From this we get that b= -4. This means the equation of a line parallel is:
y = -3x-4
It translated 4 up, 1 left
Answer: in this question the easiest way to find an answer is by cross multiplying ....i hope i am right
Step-by-step explanation:
1 hour=25miles
9hours=x
cross multiply which will give u
1x=25x9
1x=225
x=
x=225miles
hope this helps
OR
1hour= 25miles
9hours=x
so u know in 9hours the miles swam will obviously will be more so if it is more less will divide
which will be=×21 =225 miles
HOPE THIS HELPSSSSSSSSSS!!!!!!!!!!!!!
Answer:
101.00
Step-by-step explanation:
Given:
P=principal=$1
r=rate=1%=0.01
n=number of periods=12
t=time=1
Compound Interest (A)=P(1+r/n)^nt
=$1(1+0.01/12)^12×1
=$1(1+0.00083)^12
=$1(1.00083)^12
=$1(1.0100055)
=$1.0100055
Approximately
101.00
slope intercept form:
y = mx + b
m = slope
b = y-intercept
the y-intercept is the place on the y-axis (vertical) where the line crosses. In this problem, the line crosses at (0,4), meaning the y-intercept is 4.
y = mx + 4
the slope is technically the rate of change (rise over run) bewteen points.
If you take the distance from point (-1,3) and (0,4) you get a slope of 1/1, or just 1
y = 1x +4
this could also be:
y = x + 4
(because the 1 is invisible but still there)
