Answer:
There are 32 dogs and 72 animals in total.
Step-by-step explanation:
In order to find the amount of dogs, you need to set up an equation to solve for the missing variable. Let 'c' be the amount of cats and 'd' be the amount of dogs. We know that there are 40 cats, so c = 40. We also know that there are 25% more cats than dogs, so we can form an equation to express this difference: 1.25d = c, indicating that the number of cats is equal to the total number of dogs, plus an additional 25%. Since we know c = 40, we can set our second equation equal to 40: 1.25d = 40. Using inverse operations, we divide both sides by 1.25 to get d = 32. So, d + c, or 32 + 40 = 72 total animals.
Answer:
y=4x-1
Step-by-step explanation:
Slope-intercept form is written in y=mx+b
*m=slope
*b=y-intercept
From what I see,
the line hits the points (0,-1) and (1,3)
Slope is the rise (change in the y-coordinate) of the line divided by the run (change in the x-coordinate).
4÷1=4
Slope=4
y=4x+b now
The y-intercept is the value of y when the line meets the y-axis
It seems to meet at (0,-1)
So we end up with...
y=4x-1 as our equation
