Answer:
x=109 degrees
Step-by-step explanation:
so 33+39+x=180 degrees because of sum of angles in a triangle theorem. Then now you solve because of algebra
Answer:
The value of y that satisfies the system of equations is 20
Step-by-step explanation:
we have


we know that
The solution of the system of equations is the intersection point both graphs
using a graphing tool
the intersection point is (-3,20)
see the attached figure
therefore
The value of y that satisfies the system of equations is 20
Answer:
A. The increase in the number of pounds a boy gains each year.
Step-by-step explanation:
A medical student is conducting a study to track boys’ weight from age 5 to age 18. The student graphs some data and determines the line of best fit is
y = 1.73x + 80.13 ............ (1)
where x represents the age of the boys and y represents the weight of the boy corresponding to his age.
Therefore, the slope of the equation (1) represents the increase in the number of pounds a boy gains each year. (Answer)
7 squared equals 7 times 7
