The right answer is Option A.
Step-by-step explanation:
Given,
Heart rate goal = I
Heart rate reserve = H
70% of H = 
Resting heart rate = R
According to given statement,
70% of heart rate reserved is added to resting heart rate to calculate heart rate goal, therefore,
I = R + 0.7H
I=R+0.7H represents the given situation.
The right answer is Option A.

Answer:
55.75
Step-by-step explanation:
find the area of 1 side using the base and height and divide that answer by 2
5x6=30 30 divided by 2=15
all sides are equal so each side is 15
the base you do the same thing.
base is 5, height is 4.3
4.3 x 5= 21.5
divide it by 2 10.75
side 1=15
side 2= 15
side 3=15
base 1= 10.75
add all together
55.75

is equal to 2x, since it is the derivative of

.
Answer:
Part A: one solution:
Part B: x = 3, y = 4.
1) Part A: how many solutions does the pair of equations for lines A and B have?
The solution of a system of equations in a graph is given by the intersetion of the curves that represent the equations.
In this case, there are two straight lines, which intersect in one and only one point.
Hence, the system has one solution.
2) Part B: what is the solution to the equations of lines A and B?
The solution is the pair of coordinates of the intersection point. It is (3, 4).
Therefore, the solution is x = 3, y = 4.
