Answer: 44 years
Step-by-step explanation:
Let Brita's age be x and the daughter's age be y , then from the first statement :
From the second statement :
solving the resulting linear equation , add the two equations , we have
substitute 74 into equation 1 to find the value of y
Therefore :
Eva = 44 years
Answer:
Step-by-step explanation:
Step 1. Find the slope (by using the slope-formula)
m = slope
Step 2. Write the equation (using the slope and the points)
Here's how to do it:
Slope-intercept Formula whrere m = slope and b = y-intercept
Plug in the slope into the Slope-intercept Formula
Find the y-intercept (b) by using a point and substituting their x and y values
Point: (3, 7)
Step 3. Write the equation in Slope-intercept form
