Answer:
z = 4/5
Step-by-step explanation:
3(5z + 7) = 33
Divide each side by 3
3/3(5z + 7) = 33/3
5z+7 = 11
Subtract 7 from each side
5z+7-7 = 11-7
5z = 4
Divide by 5
5z/5 = 4/5
z = 4/5
Answer:
y=15
Step-by-step explanation:
y=mx+b
slope(y2-y1)/(x2-x1)
(15-15)/(6-13)
0/-7=0
y-intercept 15=0(15)+b
b=15
y=15
Answer:
x = - 2
Step-by-step explanation:
The axis of symmetry passes through the vertex, is a vertical line with equation equal to the x- coordinate of the vertex, that is
equation of axis of symmetry is x = 1
The zeros are equidistant from the axis of symmetry, on either side
x = 4 is a zero and is 3 units to the right of x = 1, so
3 units to the left of x = 1 is 1 - 3 = - 2
The other zero is therefore x = - 2
Answer:
x= 4
Step-by-step explanation:
We do like:
5x+2(1-x)=2(2x-1)
5x + 2 -2x = 4x -2
or 3x +2 = 4x -2
3x-4x +2 = -4x+4x -2
or -x +2= -2
and -x+2 -2 = -2 -2
or -x = -4
and x = 4 is the solution.
Have a good day.
