2x-y=4 find the slope of the graph

Answers

$The\ slope-intercept\ form:y=mx+b\n\nm-slope\nb-y-intercept\n\n2x-y=4\ \ \ \ /-2x\n\n-y=-2x+4\ \ \ \ \ /\cdot(-1)\n\ny=2x-4\n\nSlope:m=2$

Change it to the form of y=mx+b where m = slope and b is the intercept. So to do this just move the x over, then you divide each side by -1, because the y is negative. So you finally get y=2x-4, the slope is 2!

A group of scientist study the effect of chemical on Various strains of bacteria. Strain A started with 6000 cells and decreases at a constant rate of 2000 cells per hour after the chemical was applied. strain B started with 2000 cells and decreased at a constant rate of 1000 cells per hour after the chemical was applied. when will just strains have the same number of cells? explain

Answers

so
number in a=6000-2000x where x=number of hours

number in b=2000-1000x

when will a=b
so set them equal to each other and solve
6000-2000x=2000-1000x
subtract 6000 from both sdies
-2000x=-4000-1000x
add 1000x to both sdies
-1000x=-4000
multiply -1
1000x=4000
divide by 1000
x=4

in 4 hours, they will be the same, but, their numbers will be negative, so there is actually no real life time when they will be the same observe
1 hour: a=4000, b=1000
2 hour a=2000 b=0
3 hour a=0 b=-1000
4 hour a=-2000 b-=-2000
but you can't have -2000 cells, you can only have 0 or more than 0

Final answer:

Strain A and Strain B will have the same number of cells after 2 hours.

Explanation:

To find out when the two strains of bacteria will have the same number of cells, we need to calculate the time it takes for each strain to reach the same cell count. Let's start with Strain A, which decreases at a rate of 2000 cells per hour. We can set up an equation:

6000 - 2000t = 2000

Solving for t, we find that it will take 2 hours for Strain A to reach the same cell count as Strain B. Therefore, the two strains will have the same number of cells after 2 hours.

If (-3, y) lies on the graph of y = 3x, then y =

Answers

y = 3 x
(-3, y ) , x = -3
y = 3 · ( -3 )
y = - 9
Thank you.

Answer:

The value of y=-9

Step-by-step explanation:

If (-3, y) lies on the graph of y = 3x

If any point satisfy the equation or graph. We get true for that point.

Now, we substitute the point into equation and left side is equivalent to right side.

Put x=-3 and to solve for y

y=3(-3)

y=-9

If x=-3 then y=-9

Hence, The value of y=-9
