Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4
Answer:
lol
Step-by-step explanation:
Answer:
Answer is x= 15
Step-by-step explanation:
2= 7/4 + 1/4x
step 1: Add 7/4 on both sides
step 2: multiply both sides by 4
In the triangle XYB
cos(x)=XY/XB
in the triangle AYZ
cos(z)=YZ/AZ
we know that
cos(x)=cos(z) and XY=YZ
therefore
XY/XB=YZ/AZ-------------- > (XY/YZ)=(XB/AZ) remember that XY=YZ
1=(XB/AZ)---------- > XB=AZ---------- > the statement was proved
Actually the given equation 15 + 5x is a linear equation.
We can see that the equation is in the form of:
y = mx + b
where,
m = slope = 5
b = y intercept = 15
Since the slope is 5, therefore this means that changing
the value of x by 1 changes the value of the cost of the permit by 5. So for
every 1 change in x, there is a corresponding 5 change in the cost of the
permit.
