y = 4x - 9
y = x - 3
Step 2: Solve for x
Substitute in y: 4x - 9 = x - 3Subtract x on both sides: 3x - 9 = -3Add 9 to both sides: 3x = 6Divide 3 on both sides: x = 2Step 3: Solve for y

If C is the midpoint of BD, what is the coordinate of point C if point B is at 0?
Answer:
It depends on where point D is placed so C > 0
Step-by-step explanation:
As i said above
We want to find the coordinate of C given that it is the midpoint of BD.
We know that B is at 0, so we can assume that each letter represents a position on the number line.
Then we can assume that D is located at a number different than zero, let's assume that D is located at the value d.
Then the segment BD goes from 0 to d, so its length is d.
Then the midpoint is at the middle, at d/2 plus the smallest value, 0:
C = d/2 + 0 = d/2

x = 3 and y =

UIN
x = 3 and y =
OM
Answer:
3y = 6 - 2 ( 0 ) take
x zero and find value of y
3y = 6 - 2 ( 0 )
3y = 6 - 0
3y = 6
both sides divide by 3
ans : y = 2
now we can find so the value of x
3y = 6 - 2x
3( 0 ) = 6 - 2x
when we find the value x we take y ( 0 ) zero
3 ( 0 ) = 6 - 2x
0 = 6 - 2x
0 + 6 = - 2x
6 = -2x
both sides divide by -2
ans or value of x is 3
Step-by-step explanation:
first
- find one of the values of x and y
two :
- when you solving this
take y ( 0 ) if you search / find the value of X

Answer:
y=3x+3
How I got it:
from the graph, you can tell that the slope is 3/1, or 3 by counting up 3 on a point, then over 1.
Slope = 3
then you can tell the y intercept is 3 by.. well looking at where the line intercepts the y axis.
Y intercept = 3
the slope-intercept formula is:
y=mx+b
m being the slope, b being the y intercept. now you just plug in what you know!
y=3x+3, which is the answer
solve
log5(2)+log5(x)-log5(x-1)=log5(3)

An airplane makes a round-trip supply run that takes a total of 6 hours and is 350 miles each direction. The air current going to the destination is
in the direction of the plane at 20 miles per hour. The air current traveling back to the starting point is against the plane at 20 miles per hour. Let
x represent the speed of the airplane, in mies per hour, when there is no wind.
Replace the values of a, b and c to create the equation that describes this situation.
Answer:
the anwser is x and it represents 350
Step-by-step explanation:
The speed of the airplane when there is no wind will be 116.67 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
An airplane makes a round-trip supply run that takes a total of 6 hours and is 350 miles in each direction.
The air current going to the destination is in the direction of the plane at 20 miles per hour.
The air current traveling back to the starting point is against the plane at 20 miles per hour.
Let x represent the speed of the airplane, in miles per hour, when there is no wind.
Then the speed of the airplane when there is no wind will be given by the average speed.
Then we have
x = (350 + 350) / 6
x = 700 / 6
x = 116.67 miles per hour

6.8x+9.3= -9.4+3.4(2-5x)
Answer: the answer to this is x=0.5
Step-by-step explanation:
In order to solve this you have to combine the multiplied terms into a single fraction so its going to look like this - 34x/5 + 9.3= -9.4+3.4(2-5x)
The reposition your terms and put together your multiplied terms into a fraction,Once you have that done distribute them
Subtract 9.3 on both sides.you may simplify and then multiply all the terms with the same value to get rid of the denominators from the fractions
also add 85x to both sides then finally divide both side by the same term which get you -59.5/119 and then simplify and you get -0.5
so x= -0.5
Answer:
x=-0.5
Step-by-step explanation:
step 1
6.8x+9.3=-9.4+3.4(2-5x)
6.8x+9.3=-9.4+(3.4)(2)+(3.4)(-5x) distribute
6.8x+9.3=-9.4+6.8+-17x
6.8x+9.3=(-17x)+(-9.4+6.8) combine like terms
6.8x+9.3=-17x+-2.6
6.8x+9.3=-17x-2.6
step 2
add 17x to both sides.
6.8x+9.3+17x=-17x2.6+17x
23.8x+9.3=-2.6
step 3
subtract 9.3 from both sides.
23.8x+9.3-9.3=-2.6-9.3
23.8x=-119
step 4
divide both sides by 23.8
23.8x/23.8= -11.9/23.8
The answer is =-0.5

a cow heart beat 325 in 5 minutes. about how many times does a cow's heart beat in 2 minutes?
Answer:
130
Step-by-step explanation:
You can make a ratio - 325:5, then we can simplify it to 65:1, where we are comparing # of beats in 1 minute. Now, we can just multiply both sides by two, getting us 130:2, which is just 130 beats.
