Answer:
x = 1/5, y = 6
Step-by-step explanation:
5x + y = 7
y = 7 - 5x
Set equations equal to each other to eliminate y
7 - 5x = 20x + 2
7 = 25x + 2
5 = 25x
x = 1/5
y = 7 - 5(1/5)
y = 7 - 1
y = 6

Step-by-step explanation:
The centroid divides the length of each median in 2:1 ratio.
The length of the part between the vertex and the centroid is twice the length between the centroid and the mid-point of the opposite side.
When CD is the median, C is the vertex and D is the midpoint of AE.
CG = 2 × DG
6.5= 2(3x- 11)
6.5 = 6x -22
6x= 6.5+22
6x= 28.5
x= 28.5/6
x= 4.75
optionB
Answer:
f(-3) = -7
Step-by-step explanation:
Given:
f(x) = 4x + 5
x = -3
Plug in -3 for x in the equation:
f(-3) = 4(-3) + 5
Remember to follow PEMDAS. First multiply, then add:
f(-3) = 4(-3) + 5
f(-3) = -12 + 5
f(-3) = -7
f(-3) = -7 is your answer.
