The formula of a slope:
We have the points (4, -4) and (k, -1) and the slope m = 34.
Substitute:
Answer:
a)
Step-by-step explanation:
5x - 4 = −2x + 3
-5x - 5x
____________
−4 = −7x + 3
- 3 - 3
_________
−7 = −7x
__ ___
−7 −7
1 = x [Plug this back into both equations above to get the y-coordinate of 1]; 1 = y
I am joyous to assist you anytime.
For this case, the first thing we must do is define variables.
We have then:
x: Maggie's age
y: Age of Maggie's brother
We write the system of equations that models the problem.
We have then:
We solve the system of equations.
For this, we use substitution:
From here, we clear the value of x:
Answer:
