Answer:
±2sqrt(10) = x
Step-by-step explanation:
40 - x^2 = 0
Add x^2 to each side
40 - x^2+x^2 = x^2
40 = x^2
Take the square root of each side
sqrt(40) = sqrt(x^2)
±sqrt(40) = x
±sqrt(4) sqrt(10) = x
±2sqrt(10) = x
Answer: I would think
6-0
12-1
30-2
Step-by-step explanation:
Answer:
We can infer a cause-and-effect relationship because multiple variables were included.
Step-by-step explanation:
The multiple attributes for the divorced ones are
1) less physically active
2) an unhealthy weight,
3) smokers.
The attribute showing the % of the married is
1) death
So when we compare the two groups married and divorced we see different variables are involved in evaluating the percentage.
This shows a cause and effect involving multiple variables.
In cause and effect one variable is dependent and the other is independent.
The cause is the independent variable and effect is the dependent variable.
CAUSE EFFECT
Married Death
Divorced 1) less physically active
2) an unhealthy weight,
3) smokers.
Y=3x+7
Formula- y=mx+b
B is y intercept
M is slope
Hope this helps!!
So we set it up like beofre
c=number of calzones
s=number of slices
total of 59 so
c+s=59
total money was 456
9c+6s=456
we can divide both sides by 3 to simplify
3c+2s=152
use subsitution
c+s=59
minus s both sides
c=59-s
subsitute 59-s for c in other equation
3c+2s=152
3(59-s)+2s=152
177-3s+2s=152
177-s=152
minus 177 both sides
-s=-25
s=25
sub back
c=59-s
c=59-25
c=34
34 calzones
25 slices
