Answer:
if this is in an inequality problem no because you can only combine like terms such as combining m and m and no variable numbers together you cannot subtract a variable from a number unless you have what the variable is equal to. correct me if im wrong
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
x- intercept is where the equation intersect the x-axis. So, at x-axis y = 0
2x + 4*0 = 20
2x = 20
Divide both sides by 2
2x /2 = 20/2
x = 10
Answer:
c. There is no difference in the length between male and female babies
Step-by-step explanation:
When a confidence interval contains a zero, then there is no statistically significant different between the two group means because this means that there is a zero in the difference between the groups and a zero in the difference means there is no difference.
Properly formula based step solved
So, you can do this one of two ways.
The first is knowing what the numbers in your equation represent:
For example: y=mx+b in this case "b" is 9. b is the y-value when x=0. So the first point on our graph is (0,9). Next we have to pick an xvalue to solve for another y-coordinate.
I chose x= -3. Plug x into the equation to get y.
y=3x+9
y=3(-3)+9
y=(-9)+9
y=0
So, our second point is (-3,0).
