Answer:
4, 5.6, 4.5
Step-by-step explanation:
a:
5x + 2 = 22
5x = 20
x = 4
b:
2(5x-3) = 50
10x - 6 = 50
10x = 56
x = 5.6
c:
5(2x + 1) = 50
10x + 5 = 50
10x = 45
x = 4.5
Answer:
"moderate negative"
Step-by-step explanation:
When two variables are correlated, a tendency, negative or positive, can be distinguished in the dispersion chart.
When the trend is positive it means that one variable increases when the other also increases.
When the trend is negative it means that one variable decreases as the other increases ..
The relationship between both variables can be strong or weak.
If the relationship is strong, the points in the scatter diagram will increasingly resemble a line (if it is a linear relationship).
If the relationship is weak, the points will be more and more scattered without any relation between them.
In this case it is observed that when the years increase the population decreases. Therefore it is a negative relationship. The distribution of the points resemble moderately to a straight line. Therefore, the correct option is "moderate negative"
If u multiply and simplify the answer is 1/16.
Nancy grew the largest pumpkin since it weight more than Karen’s pumpkin
Minus 6 both sides
7x²-x-6=0
hmm
using ac method we get
7x²-7x+6x-6=0
group
(7x²-7x)+(6x-6)=0
7x(x-1)+6(x-1)=0
undistribute
(7x+6)(x-1)=0
set to zero
7x+6=0
7x=-6
x=-6/7
x-1=0
x=1
x=-6/7 or 1
